Abstract
In order to study the micro-distributin of anchovy Engraulis japonica (HOUTTUYN) eggs and larvae, from the point of view of reproduction, consecutive net samplings were carried out by making distance of net towing as short as possible. The number of samplings was 20 times at each station. The distance of unit net towing was about 60 m at 2 knots per minute. Total number of stations was 23.
A unique concentrated distribution of eggs and larvae was observed in the area of collection formed by the ocean current.
Anchovy eggs are distributed in a concentrated from like a patchiness on both large and small scale
It is considered that the chance of encounter with the prey or predator are influenced by these concentrations of the eggs and larvae.
