Abstract

MARINE teleost fishes typically produce large numbers of eggs. After the egg stage, which is usually planktonic, hatching liberates prolarvae which feed for some days on their supply of embryonic yolk. The larvae later feed actively in the plankton until metamorphosis, after which their mode of life may alter considerably. With high fecundity it is clear that mortality before the attainment of maturity must be enormous, and it has long been supposed that most of this mortality occurs during the egg and larval stages1. The pattern and causes of this mortality, however, remain obscure, constituting one of the most fundamental problems in contemporary fisheries biology.
