Marine products: the bright side and the dark side

The bright side:
“Taka Ashi Gani” (“Tall Leg Crab”), the largest crab in the world found in Suruga Bay, notably off the northwestern part of Izu peninsula has significantly in numbers in recent years.
Fishermen realized they were catching to many young specimen in the deep sea nets. They decided to preserve the caught crabs and with the help of Heda Marine Association taught local children about the importance to preserve marine resources and replenish existing stocks when they show the crabs to the kids every year before releasing them back to depths of 500 metres about one kilometre off Heda Harbour.

The dark side:

Poachers have increasingly caught “uni” (sea urchins) and “namko” (Sea slug/beche de mer) and the Japanese had to take drastic measures with boat confiscations, heavy fines (between 100,000 yen and 2,000,000 yen) and even prison sentences.
Sea urchins will find high prices on the Japanese markets while China and Hong Kong have an unquenchable craving for sea slugs.
Both command higher and higher prices, due to the decreasing catches and measures to preserve stocks.
As an indication, illegal poaching cases increased from over 900 in 2002 to more than 1,200 in 2004 and still on the way up!
On the other hand the legal export of sea slugs has increased by 43.5 % from 2004 to 2005 to reach 7,900,000,000 yen in sales of which China’s share amounts to 520,000,000 yen, an increase of 60% in one single year.
The total illegal catch was 32 tonnes last year in Hokkaido.

  1. I think it’s an “old wife’s tale” 🙂 I just recall a TV show with “The Two Fat Ladies” eating crab on the beach and some warning about that part. I had a rotten plateau de fruits de mer recently – the crab had been in a fridge for godness knows how long, and the flavour was disagreeable. Fresh or not at all seems to be a good maxim. for info on the dynamic duo.


  2. I wonder, because we never eat that particular part. But as far as I know I have never heard of poisining from crabs caught at deep depths!
    It could be that crabs caught in shallow waters suck in polluting agents like mussles do”


  3. Caviar also has a dark side! Before the USSR went under it was very common ( and cheap) here. The irony was in 1989 that you couldn’t get a decent meal in Prague, but you could seek comfort in real Russian vodka and cavair!

    I love crab 🙂 is it true that the “dead men’s fingers” are poisonous? They are the spongy bit.
