The caterer, which has businesses that often serve an upmarket clientele demanding rare and exotic fish, changed the number of slippery friends on its "Fish to Avoid" list, from 13 to 69.
The move comes at a time when dwindling fish stocks, especially that of the rare and tasty blue fin tuna, are constantly in the news.
The species on Compass's Fish to Avoid list have been identified by the MCS (Marine Conservation Society) as the most vulnerable to over-fishing and/or are fished using methods that cause damage to the environment or non-target species. The list includes four varieties of skate, five tunas and two types of plaice.
Compass created its Sustainable Seafood Guidelines, including its Fish to Avoid list, in October 2008. Blue fin tuna was included in the original list and in June 2009 swordfish was added, both in accordance with the MCS.
