The recent post over at Dynamics of Cats, Pensive on Penzim, discusses the hype about a new cod-based cure for avian flu.
So, what is the big deal? Well, probably nothing, there are no clinical trials or safety studies yet, but since the stakes are high, it is worth contemplating.
Avoid Atlantic cod; it has been fished heavily for the past 50 years, resulting in massive population declines. Scientists agree that we are now fishing the last 10% of this population…Despite strict management in the U.S. and Canada, cod populations remain overfished. Canadian populations are so low that some are listed as endangered or threatened. Most stocks in the Northeast Atlantic, except for the Icelandic and Northeast Arctic cod stocks, are also in extremely poor condition.
So avoid all cod? No…
Other gear types, such as hook-and-line and bottom longline, do not damage the seafloor. Icelandic and Northeast Arctic (Barents Sea) cod caught with hook and line, Danish seine, gillnet and bottom longline gear are Good Alternatives to other Atlantic cod. Cod from these fisheries are at relatively better population levels and are caught with gear that does not damage the seafloor.
So in summary Atlantic Cod bad, unless Icelandic caught with hook and line (which you are unlikely to know or find out so just avoid).
Pacific Cod, Gadus macrocephalus, good…good from trawls, best from longline, trap or hook-and-line.
Thank God I can still have my fish and chips.
So back to Penzim (Dynamics of Cats)….
Ok – so there’s step from cold pressed cod liver oil, to enzyme from cod guts, but it is all same-same, eh?
Of course modern trawlers gut and discard the innards at sea, which pleases the sea gulls tremendously, I guess they’ll start keeping the guts, until a synthesis is found.
Currently the only source of Penzim is cod guts. Not bad because guts are discarded. Using the whole fish good. But how much Penzim can be obtained from a single gut? Is the current amount guts sufficient for a Penzim demand? Or will this increase cod demand? Will increased profitability for cod from Penzim lead to overdepletion?
Of course the other problem…The cod fishing industry get a new arguement, “We need to overfish cod because we are saving lives! And don’t forget about the children!”
