- Nearly one third of the world's fish stocks are overfished--the Atlantic is the hardest hit
- Majority of the world's fishing fleet is concentrated in Asian waters
- Trawling, though banned in many countries, bulldozes the seabed and catches sea life indiscriminantely--more than 50% that are caught are discarded
- In Africa, only the carcasses of the NIle perch are affordable sources of protein for some Tanzanians living around Lake Victoria
- Perch fillets are stripped in 35 lakeside processing plants and shipped north, mainly to Europe, but also Israel
- With years of overfishing in Africa, perch stocks have fallen drastically--imperiling the livelihoods of more than 100,000 fisherman, and depriving local people of food
- To suply the world's sushi markets, the giant bluefin tuna is fished in the Mediterranean at four times the sustainable rate
- The bluefin tuna is being fattened off the coast of Spain--69 ranches have been created in the Mediterranean Sea in the last 10 years--this is demolishing the fish stocks
- In Europe, fisheries management is difficult, due to the number of countries bordering the seas
- Aquaculture now contributes to nearly 50% of the world's seafood--filling the void left by declining stocks in the wild

Sushi Anyone?
One of my friends invited me to go out for sushi tonight (coincidence considering todays lecture!!)...fair enough, I am a vegetarian and I had class so I couldn't/wouldn't go....BUT I did want to mention Herring Worm Disease (after we discussed it in class today) to her...just to bug her a little!!
The presence of parasites in fish is very common, but most of them are of little concern with regard to economics or public health. Anisakiasis is a gastrointestinal parasitosis caused by the larval stages of anisakid nematodes. Humans acquire the disease by eating raw or improperly cooked or preserved seafood. Surviving worms will then penetrate the gut wall and enter the peritoneal cavity. Symptoms are often non-specific with abdominal pain, nausea and vomiting. Vague abdominal pain and possibly fewer may persist for weeks. Anisakiasis is common in Europe (the Netherlands), Japan and the US.

Lunenburg-The Fisheries Museum
My grandfather grew up as a fisherman, and I honestly didn't realize how difficult and dangerous of a job it was. I definitely attained a much greater respect for his work.
I asked Nancy what the general feeling was in Lunenberg in regards to bottom trawling was...she said that they are making great efforts to become more sustainable fishers, and they have developed a 2 tierd net, so when they are fishing haddock for example, there will be a barrier in one level, and the cod have a natural instinct to duck, therefore do not catch the cod.
The old way of fishing was intensely difficult, and really heoric, especially going out in the smaller boats, by themselves or with another mate. Hooking two miles of net by hand would be exhausting! I was also astounded that those small boats could hold up to 2000 lbs of fish at a time!!!
I didn't know much about the Bluenose Expeditions, but I do intend to do more research on that in another blog. ---Not to mention the massive size of that lobster crustacean...and the metamorphosism of Halibut! I have grown up working in a seafood restaurant and never knew that happened!!! It was really neat to see that the camoflauge themselves too!!!
Nancy's (our tour guide) last name is Knickle which seems to be a well known family in Lunenberg, from company's named after them, to many men in their family who lost their lives. I couldn't believe that 9 year olds or 13 year olds would be out working on these ships! What a different time it is today!!
Lunenberg was a beautiful town and is a great example of a self-sustaining coastal community! It is nice to see that not every place in the world has become inundated with commercialization....even if they do have a few tacky tourist shops!!!

Coral Reefs: The Rainforests of our Oceans
Coral reefs are estimated to cover 284,300 square kilometres of our oceans.
The Great Barrier Reef is the largest coral reef system in the world, located off the coast of Queensland, Australia. The Belize Barrier Reef is the second largest reef in the world, located off the coast of Belize, Central America. An abundance of reefs can be found around the Maldives as well. Coral reefs support an abundance of sea life and biodiversity. However, human activities are harming our coral reefs in a great way. Pollution, sea traffic and overfishing have caused the greatest destruction to our reef systems. if destruction increases at the current rate, 70% of the world’s coral reefs will have disappeared within 50 years. This loss would be an economic loss for peoples living in the tropics. It is estimated that about 60% of the world’s reefs are at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where an enormous 80% of reefs are considered endangered.

Beach Clean Up
As I was walking home from the library that evening in the rain, I noticed the immense amount of garbage in our streets, and I thought if we are this lazy on land, how lazy are we with our garbage in the ocean?! In Monday's Ocean Use and Management class, Cathy mentioned in the 1950's parts of Nova Scotia dumped their waste into the ocean, over cliffs. I am sure that is still not all that far off with boats traveling in the sea.
A major societal wake up needs to occur. For example, the abundance of cigarette butts on the ground. Yes its a good thing that patrons aren't smoking in public venues and subjecting others to second hand smoke, but how is it okay to subject the public to your butts littering the ground? The city should put ash tray's around the city to deter this pollution. These get washed away by rainwater and enter our sewar system, which ultimately ends up in our oceans.
We need to WAKE UP!!!

Sea Shepard
The Sea Shepherd Conservation Society was founded in 1977 in Vancouver BC by Captain Paul Watson. The mandate of the organization was marine mammal protection and conservation with an immediate goal of shutting down illegal whaling and sealing operations.
Founder, Paul Watson, is born and raised in Canada, with a vast history of activism. He was a Canadian Coast Guard and was the co-founder of Green Peace. In June 1977, Paul Watson resigned from the Greenpeace Foundation because of disagreements with the emerging bureaucratic structure of the organization. Patrick Moore had replaced Robert Hunter and was opposed to direct action campaigns. Moore had informed Watson that he would not be allowed to lead another seal campaign. Paul left Greenpeace because he felt the original goals of the organization were being compromised, and because he saw a global need to continue direct action conservation activities on the high seas by an organization that would enforce laws protecting marine wildlife.
To answer that need, that same year, Paul founded the Sea Shepherd Conservation Society - dedicated to research, investigation and enforcement of laws, treaties, resolutions and regulations established to protect marine wildlife worldwide. In December 1978, with the assistance of the Fund for Animals, Paul purchased a North Atlantic trawler in Britain and converted her into the conservation enforcement vessel Sea Shepherd.
Paul Watson has dedicated his life to the conservation of animals, and as it seems will stop at almost nothing to achieve these results. As he says in the film, it only takes a few people to change the way the world works, for example, Ghandi. It is not our governements that change the world, it is mass movements of the generaly public.

Rip Currents
There are signs to look for in the water to see if a rip current is present. Rip currents can be recognized by unusually calm waters, caused by the channel of water flowing out. The color of the water may be different from the surrounding area. Also, the waterline is lower on the shore near a rip current. It is advisable to look for the existence of a rip current before heading into the water.
Rip currents can also be extremely useful for surfers as they save the effort of having to paddle out to catch a set. They can also be used by lifeguards, who can use them to get out from the shore to perform a rescue much quicker than they could by swimming/paddling through the waves.
While the precise conditions leading to a rip current are not known, the general picture is as follows. When wind and waves push water towards the shore, the previous backwash is often pushed sideways by the oncoming waves. This water streams along the shoreline until it finds an exit back to the sea. The resulting rip current is usually narrow and located in a trench between sandbars, under piers or along jetties. The current is strongest at the surface, and can dampen incoming waves, leading to the illusion of a particularly calm area, luring some swimmers in. Rip currents are stronger when the surf is rough (such as during high onshore winds, or when a strong hurricane is far offshore) or when the tide is low.

Trapped Whale in the Annapolis River
Sluice followed the sonar carrot for more than 4 kilometers, and swam within 35 metres of the Annapolis Royal Tidal Generating Station before turning around.
Due to the abundant supply of fish in the river, the whale most likely enjoyed his stay in Annapolis.
As a result of the changing tides, on some days there was only a 30 minute window for Sluice to make a run for it.
To understand their action plan, please view this video: http://www.cbc.ca/newsatsixns/media/20040826ns_whale_intvu.ram

"Symmetry in motion, two whales surface and exhale in union, emerging to the rarest of North Atlantic days—a clear sky and a glassy sea. Although small groups often maneuver in tight formation for a short time...research suggests that the social bonds of most bottlenose whales are as transient as a teenager's. A month from now these whales will be swimming in sync with new best friends."

Using Seals, Sea Lions, Satellites Help Map Ocean
The information can then be used to create detailed 3-D models, such as this temperature profile of the North Pacific generated by seven elephant seals.
"Satellites provide a two-dimensional view of the ocean," team co-leader Yi Chao of JPL said in a NASA release. "Animals give us a slice of the ocean. They're like weather balloons in reverse."
"As we are getting more data from the sea and improving our computer models," he continued, "we should be able to make routine ocean forecasts, similar to what meteorologists have been doing in the past few decades. People who open the newspaper or turn on the TV in the morning will see the updated ocean forecast and make appropriate decisions as they plan their activities on the sea."
Team co-leader Daniel Costa, a marine biologist at UCSC, said the project will also help researchers better understand how animals interact with their ocean environments.
"Just as there are different habitats on land, the ocean has fine-scale features that are very important to animals," Costa said in the media release. "We want to be able to look at the ocean and say the equivalent of 'this is a grassland' or 'this is a forest.'"

Hydrothermal Vents
Water shoots out of the fastest and largest black smokers at about 300 gallons (1,135 liters) a minute—twice the flow from a typical fire hose and enough to fill a bathtub in a few seconds.
Most instruments used to measure flow, however, are short-lived when inserted in the scalding hot, acidic, and mineral-rich fluid.

Hybrid Cars
Exploding the myths about hybrid cars
Insuring your hybrid
Insuring a hybrid vehicle is no different than insuring a conventional car. There are no special steps or considerations and it doesn't cost extra. The premiums you pay will reflect the class of car, your driving record, how much you use your car, where you live, and how much coverage you want.
Today’s hybrid cars combine an electric motor with an internal gasoline combustion engine to produce a vehicle that gets awesome mileage.
But the misconceptions about hybrids are preventing some buyers from even considering a test drive. Here are five of the most common myths about these vehicles:
Myth #1: There isn’t much to choose from
“There are five different models of hybrids available today”, says Brad Berman, editor of www.hybridcars.com and a hybrid driver himself. They are:
Ford Escape Hybrid, the first SUV hybrid;
Honda Accord Hybrid, a family sedan;
Honda Civic Hybrid, a compact;
Honda Insight, a two-door coupe;
Toyota Prius, a mid-size sedan.
And soon there may be more. “There is a growing trend with car manufacturers”, notes Berman, “to add hybrid versions of their existing cars. For example, DaimlerChrysler and GM have announced plans to join the hybrid-car market”. Even luxury car manufacturers are jumping on the hybrid-wagon: the Lexus RX400h, billed as the world's first luxury hybrid SUV, is slated to be available this year.
Smart tip: “You may have to wait for the model of your choice”, cautions Berman, “since today supply simply doesn't meet demand”. He does stress, though, that a hybrid is well worth the wait.
Myth #2: You’ll save a bundle
“Hybrids are the most fuel-efficient cars in the world”, explains Berman. Depending on what, where and how much you drive, you may save anywhere from $200 to $1,000 a year on gas.
Smart tip: To compare the gas mileage of your conventional car with a hybrid model, use the gas mileage impact calculator at www.hybridcars.com/calculator.
The flip side, unfortunately, is that they cost more up-front. Whether the long-term fuel savings outweigh the higher sticker price will depend on a number of factors, including where you live, what you buy, and how much you drive.
But Berman advises to see beyond the cost savings at the pumps. “Since hybrids use less gas, dependency on foreign oil is reduced”, he explains. “This means that drivers will be less vulnerable to price shocks at the pumps”. The other reason, of course, is for the environmental benefits. “Simply put, less gas equals less pollution”, he says.
Myth #3: They’re expensive to maintain
“There’s no reason for maintenance to cost more for a hybrid than a regular car”, Berman declares. “One of the most popular misconceptions is that a hybrid’s rechargeable battery could wear out and be expensive to replace. But hybrid battery packs are designed to last for the lifetime of the car, and are covered by warranty for eight to 10 years”.
And you don't need to plug in your car every night to recharge the battery. “Energy is recovered during braking”, he explains.
Smart tip: For regular maintenance, take your hybrid to your dealer to get the best service. As hybrids become more and more popular, more independent mechanics will be able to provide expert care.
Myth #4: Hybrids are good for fair-weather driving only
Not so, says Berman. “Based on my own experiences, everything I’ve read and the experts I’ve consulted, there is no difference between driving a hybrid and a conventional car in bad winter weather or during scorching summer heat”.
Take a look at a manufacturer’s specifications if extreme cold or heat is a concern to you. Berman uses Honda as an example of what you can expect: “Honda specs indicate that their hybrids run just fine at temperatures as low as -30°C [-22°F] and as high as 60°C [140°F]”.
Smart tip: To provide maximum fuel efficiency, most hybrids come with low-resistance tires. As with any car, you may want to invest in snow tires.
Myth #5: Hybrids aren’t as safe as conventional cars
The misconception that hybrids aren’t as safe as conventional cars is because of their size. “People feel safer in larger cars”, says Berman. “But statistics don’t back up that claim”.
Today’s hybrids rank high in safety ratings for their weight class.
Smart tip: To check on the safety rating of most makes and models, visit the National Highway Traffic Safety Administration Website.

Westport Innovations

This summer I worked for a company located in Vancouver, British Columbia which develops natural gas and hydrogen fuelled engines. Westport is a joint venture with Cummins, (Cummins is known for their diesel engines). Westport states on their website: The world faces major challenges in the 21st century that are significantly impacted by transportation growth: "oil supply security and the peak in global oil production, rising air pollution levels in the world's rapidly growing cities, and increasing greenhouse gas emissions linked to climate change and global warming. Vehicle growth and oil demand in China alone are expected to increase by more than 300% over the next 25 years" ( http://www.westport.com/the_big_picture/index.php). High transportation growth markets like China, India, and Brazil are driving the future energy picture for transportation. All three have been moving towards increased natural gas utilisation. Ultimately, Westport Innovations believes that the global deployment of natural gas vehicles with Westport technologies can be significant factors in:
- reducing dependence on oil, allowing many countries to use abundant, indigenous natural gas,
- mitigating the effects of air pollution in cities, and
- providing the bridge towards hydrogen-based transportation.
Westport engine technologies combine the power, fuel-efficiency, and performance of diesel engines with the low emissions and operating cost benefits achieved by replacing diesel fuel with natural gas.
Natural gas is a fuel that is extracted from our earth which does present dangers. However, as an alternative to petroleum it is definitely something that should be considered.
Over Christmas break while I was home, I noticed that Translink had purchased a new fleet of buses for the lower mainland district. I was disappointed to note that these buses were not lower emissions buses and were in fact run on diesel. A ground breaking company such as Westport Innovations not to mention Ballard (battery operated) are located in Vancouver. It is stunning that these would be overlooked. China who is leading in reducing emissions is currently implementing these buses throughout their major cities.

The Giant Squid

The fact that this specie was caught in a bottom trawler reitterates the fact that bottom trawlers are destroying ocean ecosystems by scooping up species which are not intended or needed to be caught.The Colosssal squid has one of the largest beaks known of any squid and also has unique swivelling hooks on the clubs at the ends of its tentacles. This combination allows it to attack fish as large as the Patagonian toothfish and probably to also attempt to maul sperm whales.

Harbour cleanup delayed 3 months
By AMY PUGSLEY FRASER City Hall Reporter
Halifax Harbour’s sewage cleanup project is backed up by three months but the delay could save city hall $3 million, says the project director.
"From HRM’s point of view, this is a positive financial story," Brad Anguish told councillors Tuesday night at the regular weekly meeting.
"Albeit, nobody is happy that we’re not receiving the environmental benefits when we thought we would."
The $333-million Harbour Solutions project includes a $133-million contract to D&D Water Solutions Ltd. for the design, construction and commissioning of three sewage treatment plants in Halifax, Dartmouth and Herring Cove.
Mr. Anguish told council Tuesday night that the contractor, jointly owned by Dexter Construction Co. Ltd. and Degremont Ltee., has pushed the system startup to September 2008.
"But our water quality objectives are still on track for 2008," he said.
The delay is attributed to difficulties procuring equipment, design co-ordination and code interpretation with subcontractors and the availability of short-notice labour to make up the schedule, Mr. Anguish said.
"You can throw all kinds of money at this problem but the reality is, the labour isn’t always there when you want it anymore."
The confined space within the Halifax treatment plant also limits the work, he said.
Taxpayers won’t get dinged for the delay, he said.
In fact, everything is on budget and it could get cheaper.
"While it’s a penalty to the contractor, it’s a potential savings to HRM," Mr. Anguish said.
That’s because of a clause in the original contract that guarantees a maximum price and deletes the inflation adjustment for the developer if it goes over the project completion date.
"Given the very high inflation that’s happened in the construction index over the past three years, this is quite a substantial penalty," he said.
Rough calculations mean that D&D Water Solutions could lose as much as $2.5 million to $3 million, he said.
"So there is a significant financial incentive to continue to perform and meet schedule whenever possible."
As a result, he said, D&D could still finish on time.
"While it can get later, it can also get sooner," he said.
Mayor Peter Kelly, who named the cleanup of Halifax Harbour among his key issues in the last mayoral campaign in 2004, said the delay is not unusual.
"In a project of this scope with a time frame of almost five years, a delay of three months is not at all uncommon," he said Tuesday night.
"In this case, it demonstrates our contractor’s diligence in ensuring that every element of this massive project is completed to HRM’s very stringent specifications, as well as those of the federal and provincial governments."
The Harbour Solutions project is designed to stop the flow of more than 180 million litres of untreated waste water into Halifax Harbour every day.
( apugsley@herald.ca)
I had not realized that Mayor Peter Kelly had made it one of his key issues to resolve in his last mayoral campaign in 2004. I was happy to read that because the cleanup is much needed. It is important that environmental issues are being looked at as valuable and imperative to fix and maintain a better quality of our water.

The Pacific Ocean has a history of important migration routes, such as those of the Austronesians (specifically the Polynesians) from the Asian edge of the ocean to Tahiti, then to Hawaii, New Zealand, and much later to Easter Island. Spanish explorer, Vasco Núñez de Balboa (1513) discovered the Pacific ocean in the early 16th century when he crossed the Isthmus of Panama, followed by many other explorers who sailed to places such as the Philippines, New Guinea and the Solomon Islands. Important trade routes were later established.
The history of Vancouver is based around explorers who traveled by ships. For example, The coastline of Point Grey was first explored in 1791 by José María Narváez of Span, followed by George Vancouver, who also explored the harbour of Burrard Inlet in 1792. George Vancouver named various places British titles, despite the presence of Aboriginal peoples.
Due to Vancouver's location on the Pacific Rim and the western terminus of Canada's transcontinental highway and rail routes, Vancouver is one of Canada's largest industrial centres. The Port of Vancouver is Canada's largest and most diversified, participating in more than $43 billion in trade with more than 90 countries annually. These activities generate $4 billion in gross domestic product and $8.9 billion in economic output. Vancouver is becoming increasingly more populated and is surrounded by coastline and its scenic location.
Greater population and higher density brings the concern of pollution to our community, including our very important oceans, which feed the economy through the Port of Vancouver and the vast diminishing fisheries. On a global scale, the effects of global warming is causing dramatic weather events, which have become very apparent this year. For example, extremely intense windstorms, occurring at hurricane strength, heavy snowfall and extreme high temperatures in the summer and much colder than usual temperatures in the winter. Oceans regulate temperature and weather, especially in maritime regions.
