18/11/13: Extracting oil from shrimp shells; threat to tuna in the Solomon Islands; controversy over cod stocks

Canadian seafood processor Quinlan Brothers Limited has been given CAD$100,000 in a bid to determine the economic viability of extracting Omega 3-enriched oil from shrimp waste.

Preliminary research by Quinlan Brothers Limited has shown that the oil derived from shrimp shell waste is a premium nutritional supplement.

The company has sought expert advice on how to extract the oil and bring samples to market. It is exploring ways to improve the oil collection and to pre-treat shell discards.

Pew Charitable Trust, one of the worlds' leading Tuna conservation groups has announced an urgent need to reduce the number of purse seine vessels currently fishing the Pacific.

The trust argues that he increasing number of fishing boats engaging in tuna fisheries in the country’s Exclusive Economic Zone (EEZ) is a threat to the sustainability of the country’s tuna fisheries.
 
It added that more vessels means more competition  for tuna which is likely to drive down catches of skipjack and yellow fin for everyone.

Seafish, the British authority on seafood has challenged new advice from the Marine Conservation Society (MCS) with regard to North sea cod stocks.

The MCS has advised consumers to avoid eating North Sea cod, blacklisting it on the 'Fish to Avoid' list.

However, Seafish argues that consumers can buy North Sea cod with confidence, secure in the knowledge that it has been sourced from well managed fisheries using methods and practices that fall within the set parameters of the Cod Recovery Plan.
"The facts are that North Sea cod stocks have been steadily recovering for a number of years now. Fishing pressure on the stock has been decreasing since the late 1990s and is now considered by International Council for the Exploration of the Sea (ICES) to be at an appropriate level," said Tom Pickerell, technical director at Seafish.
