Researchers for the US agriculture research service (ARS) are working on a preventative vaccination for the parasitic infection known as white spot. This parasitic infection costs aquaculture and fish hobbyists about $50 million annually in losses. The idea is to use preventative treatment and rather than dosing fish individually. The aim is to create a vaccine that can be delivered in with the food or direct to the water. A new vaccine would not pose a threat to the environment like the treatment used today which can be harmful environmentally. Read more...
Chef says 'no' frankenfish debate goes on
Chef Rick Moonen is against genetically engineered fish; he does not believe that the new “fish is safe”, as has been suggested by Aquabounty Technologies. His concerns range from, if they escaped what damage would be done to the wild populations to the fact that there is no plan to label them in grocery stores. He also worries that this could cause a larger demand for smaller species to be used as feed for these frankenfish. Read more...
Farmed fish destroy wild fish
An essay found in this weeks Conservation Biology Journal, suggest that farmed fish are causing wild populations to decline. He suggests that a high density of caged farmed fish, promotes infection that affects wild populations near the fish farm. Sea lice is one example that impacts fish farms and also impacts the wild populations, even though the farmed fish survive the wild populations suffer. And if the sea-caged system is overstocked this can lead to extinction of the wild stocks near by. So do farmed fish destroy wild fish? Read more...
