Cooke aquaculture charged for banned pesticide
Cooke aquaculture, owners of Kelly Cove Salmon have been charged by Environmental Canada for its alleged release of a banned pesticide into the marine environment. The alleged release of cypermethrin-based pesticide is harmful to crustaceans and may have caused the death of lobsters in 2009. The charges are the results of two investigations by Environmental Canada carried out on December 22, 2009 and February 10, 2010. Read more ...

The Cohen commission has heard testimony for over 173 witnesses during the 125 days. Commissioner Bruce Cohen is due to write his report, and a key question is weather the salmon fish farms are incubators for disease that threaten wild stocks of salmon. During this commission the two opposing sides have argued and presented evidence to the commission. Gregory McDade, legal counsel for the Aquaculture Coalition "The real issue here is proof versus risk, the risk here is real. Don't wait for 10 years until this is proven and we have no fish left." But Alan Blair, counsel for the BC Salmon Farmers Association, said experts have already told the commission that properly managed aquaculture sites can co-exist with the marine environment.

Vegetables fed to farmed fish may have residual pesticides
Today farmed fish accounts for 50 percent of all fish consumed, a new test is being used to detect pesticide residue in farmed fish, has shown how high the risk of contamination is. With the rising cost of fish feed in the world and the ever growing shortage of ingredients for fishmeal, aquaculture is turning to crops like soya, maize and rape to use in fish feed. It is believed that the contamination comes from the vegetable matter being fed to farmed fish. Scientists at the Fraunhofer Institute for Molecular Biology and Applied Ecology IME in Schmallenberg have developed a system to test whether chemical substances accumulate in fish that are fed contaminated feed.

Important amino acids for advanced animal nutrition
Evonik Industries is the only company in the world to produce and market all four important amino acids for the advanced animal nutrition: MetAMINO® (Dl-methionine), Biolys (L-lysine), ThreAMINO® (L-threonine) and TrypAMINO® (L-tryptophan). MetAMINO® is DL-methionine manufactured at purity levels exceeding 99 percent and plays a central role in ensuring balanced nutrition and optimum growth of poultry, swine and various aqua cultured fishes and shrimps. MetAMINO® for aquaculture allows for reducing aqua feed costs by providing better options to balance the amino acid composition of pure vegetable and fishmeal containing aqua diets. While reduced nitrogen pollution will be a considerable contribution for environmental protection, an optimised diet will reveal better growth and feed efficiency. Due to its low water solubility, risk of leaching is minimised, particularly in comparison to competitor products. Particle size distribution ensures homogenous mixability in aquafeed and high availability to fish and shrimp confirmed by growth responses in various aquatic species. In over 100 countries of the world the company delivers innovative services and products, and contributes to customers’ profitability while enabling healthy and environmentally friendly animal nutrition.
