Sustainable Fisheries
32% of the world's fisheries are overexploited, depleted or recovering, which threatens the health, economy, and livelihoods of communities all over the world. The global fishing fleet is estimated to be 250% larger than needed to catch what the ocean can sustainably produce.

There are a number of issues that need to be addressed quickly in order to preserve fish stocks as a natural resource. These include among others:
Overfishing
Overfishing, formally defined as "situations where one or more fish stocks are reduced below predefined levels of acceptance by fishing activities", means that fish stocks are depleted to the point where they may not be able to recover. Areas such as the eastern coast of Canada and the northeastern coast of the U.S. have fished certain species to collapse, which consequently caused the fishing communities that relied on those stocks to collapse.
In some cases, depleted fish stocks have been restored; however, this is only possible when the species' ecosystem remains intact. If the species depletion causes an imbalance in the ecosystem, not only is it difficult for the depleted stocks to return to sustainable levels, other species dependent on the depleted stocks may become imbalanced, causing further problems.
Solutions
Access agreements through government deals are helping fisheries in developing nations negotiate better agreements with rich countries that will help protect the marine environment and livelihoods of fishing communities. These local people rely on fish to sustain their health and their livelihoods.

Foreign fishing fleets of enormous size and power from rich countries can overwhelm local people and deplete the fish stocks, causing further harm to the marine environment by disrupting the food chain. The more fish stocks become overexploited, the more fisheries must search for productive waters which are then quickly depleted.
The seafood industry, like all industries, is largely market driven. Seafood consumers are increasingly aware of the threats to global fish stocks, yet greater awareness is needed so that the market demands sustainable products from well-managed fisheries. A potentially powerful intervention is being implemented by organizations such as Blue Ocean Institute and the Monterey Bay Aquarium by publishing seafood guides to help consumers make informed choices when buying seafood. Furthermore, recent legislation requires fish sellers to identify the source of seafood. Some retail outlets such as Whole Foods Market are supposedly committed to preserving the ocean's resources by raising awareness and selling only products from well-managed fisheries. Organizations such as the WWF have worked with corporations such as Unilever, one of the world's largest consumer food companies, to form the Marine Stewardship Council (MSC), which provides a mechanism for identifying and certifying sustainable fisheries.
Seafood Summit brings together global representatives from the seafood industry and conservation community for in-depth discussions, presentations and networking with the goal of making the seafood marketplace environmentally, socially and economically sustainable.
Fish2fork is the world's first website to review restaurants according to whether their seafood is sustainable, and not just how it tastes. It is brought to you by the people behind the film, The End of the Line.
An independent, global charity, the MSC is headquartered in London and works to promote sustainable marine fisheries, and responsible, environmentally appropriate, socially beneficial and economically viable fishing practices. This is accomplished by the development of a set of standards, the MSC Principles and Criteria for Sustainable Fishing, to assess and certify fisheries. These standards are based on scientific data and were developed with relevant stakeholders. Third-party certifiers are used to assess MSC certified products. The MSC "seal of approval" should allow consumers to purchase fish and other seafood from well-managed sources though Daniel Pauly wrote in September, 2009 in his article titled Aquacalypse Now - The End of Fish:
At first, the MSC certified only small-scale fisheries, but lately, it has given its seal of approval to large, controversial companies. Indeed, it has begun to measure its success by the percentage of the world catch that it certifies. Encouraged by a Walton Foundation grant and Wal-Mart's goal of selling only certified fish, the MSC is actually considering certifying reduction fisheries, with the consequence that Wal-Mart, for example, will be able to sell farmed salmon shining with the ersatz glow of sustainability. (Given the devastating pollution, diseases, and parasite infestations that have plagued salmon farms in Chile, Canada, and other countries, this “Wal-Mart strategy” will, in the long term, make the MSC complicit to a giant scam.)

Fisheries News :: ScienceDailyMicroscope looks into cells of living fish
Microscopes provide valuable insights in the structure and dynamics of cells, in particular when the latter remain in their natural environment. However, this is very difficult especially for higher organisms. Researchers have now developed a new method to visualize cell structures of an eighth of a micrometer in size in living fish larvae.
Why omega-3 oils help at the cellular level
For the first time, researchers have peered inside a living mouse cell and mapped the processes that power the celebrated health benefits of omega-3 fatty acids. More profoundly, they say their findings suggest it may be possible to manipulate these processes to short-circuit inflammation before it begins, or at least help to resolve inflammation before it becomes detrimental.
The gut could reveal effect of climate change on fish
As sea temperatures rise, stocks of some fish species can decline while others may grow, reveals new research looking at gastrointestinal function in fish.
New species of fish in Sweden
Reticulated dragonet have been found in Väderöarna -- "Weather Islands" -- off the west coast of Sweden. It is not often that a new species of fish is discovered in Sweden.
Steelhead trout lose out when water is low in wine country
The competition between farmers and fish for precious water in California is intensifying in wine country, suggests a new study by biologists. The study links higher death rates for threatened juvenile steelhead trout with low water levels in the summer and the acreage of vineyards upstream.

New research offers a blueprint for the long-term sustainability of tuna caught using the pole-and-line method.
One-quarter of grouper species being fished to extinction
Groupers, a family of fishes often found in coral reefs and prized for their quality of flesh, are facing critical threats to their survival. Scientists report that 20 species are at risk of extinction if current overfishing trends continue, and an additional 22 species are near "threatened" status.
Virtual reality allows researchers to measure fish brain activity during behavior at unprecedented resolution
Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behavior.
Weed-eating fish 'help protect jobs, livelihoods'
Jobs, livelihoods and ecotourism industries can benefit from having a diverse supply of weed-eating fish on the world's coral reefs, marine researchers say. Despite their small size, relative to the sharks, whales, and turtles that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, say researchers.

An ancient killer coelacanth from Canada
Coelacanths are iconic fishes, well-known as 'living fossils.' A new extinct coelacanth is causing waves in the scientific community because it had a tuna-like forked tail and was probably a fast-moving, shark-like predator. This contrasts with living coelacanths, which are slow-moving fishes with peculiar broad tails bearing 3 lobes.
Escape response of small fish tested using a supercomputer
Researchers have for the first time succeeded in discovering the optimal escape response of fish using a supercomputer. The aim was to test whether the escape mechanism of small fish, developed in the course of evolution, is optimal for achieving the maximum escape distance in a short time.
Impaired recovery of Atlantic cod: Forage fish or other factors?
Biologists suggest the delay in recovery of Atlantic cod on the eastern Scotian Shelf could be attributed to increased predation by grey seals or other governing factors and not the effect of forage fish as previously thought.

Smalleye pigmy sharks' bellies shine: They glow for camouflage
Smalleye pigmy sharks have an eye-catching party trick: Their bellies glow. However, instead of being a giveaway, biologists have shown that the fish's shiny undersides probably provide camouflage. They also discovered that the pigmy shark and another glowing fish, the lantern shark, regulate their glow using the similar mechanisms, although the pigmy shark is probably more closely related to their common ancient ancestor.
Eight species of wild fish have been detected in aquaculture feed
Researchers have for the first time analyzed a DNA fragment from commercial feed for aquarium cichlids, aquaculture of salmon and marine fish in aquariums. The results show that in order to manufacture this feed, eight species of high trophic level fish have been used, some of them coming directly from extractive fisheries.
