Some regularities of distribution of eggs and larvae of the Baltic cod
In the period from 1954 to 1965, quantitative samples on the distribution of eggs and larvae of cod Gadus morhua were collected. It was established that one of the most important reproduction area of cod was the Bornholm Deep (Baltic Sea). The maximum density of eggs was found in the central area of...
