Genetic studies suggest that many good year classes are actually the result of a small number (a few hundred) fish that happened to hit it right. Wipe out a single pre-spawning school of fish and we may wipe out an entire year class. George, i know for a fact that this happens with clams.have seen many areas were there are a few chowders and cherries and in following years the same areas are paved with clams.though this hasn't happened very often in recent years.that statement also makes me wonder why people think that taking less fish will do anything to help the stocks.my focus would be on why aren't the fish we have aren't reproducing at a greater rate.is it because we are killing the big fish or envoirmental factors.
