A global assessment of salmon aquaculture impacts on wild salmonids Ford JS.

These new results suggest that salmon farming could seriously threaten the persistence of the world’s salmonid populations.A global assessment of salmon aquaculture impacts on wild salmonids Ford JS, Myers RA PLoS Biol 6 : e33.

But until now there has been no assessment of the significance of these effects on the population level and across the world. Ford & Myers survival of salmon and trout that swim past salmon farms to the survival of fish that never pass a salmon farm compared. Combining these five regions across the world , Ford and Myers a significant decrease in the survival of wild salmon populations that are exposed to salmon farms. This decline was as farmed salmon production increased in each region. The combination of these regional estimates, the authors find that wild populations suffer a reduction in survival or abundance of more than 50 percent when associated with farmed salmon..You can tell, saying a billionth of a gram of said toxin in one drop of liquid in just five minutes, the researchers said. Reports on tests – the most sensitive so far for the detection ricin – in Analytical Chemistry, ACS, a semi – monthly journal appears.. An anti new Reviews for sensing bioterrorism agent castor.

In an history which help protect people of possible terrorist attacks using ricin, two groups of scientists into Georgia and in New York City reporting up development of, more sensitive tests for may collection the deadly poison.

By mass explorer allow to identify test are develops ricinene by protein recognition methods, by the existing tests are typically slow, cumbersome and inaccurate.. Observed The researchers on to new study in that ricin, a ribosomal inactivating protein Used in the castor beans, one of the agents most closely to be used in acts of the an aerosol or food-related biological terrorism. Castor be readily obtained and rapidly results in death, when inhaled or ate in small quantities. There is no known antidote. Quantification of ricin also has medical applications as ricin immunoconjugates can have been used as an anti – cancer agent.
