Distribution of eggs and larvae of gadoid fishes from Stad to Lofoten during April 1976-1982. In: The propagation of cod Gadus morhua L.: an international symposium, Arendal, 14 - 17 June 1983

Abstract

Fish eggs and larvae have been sampled during the study of herring larvae distribution. Since 1976 these findings have been recorded. Most of the gadoid eggs are difficult to identify, but identification of larvae and knowledge of spawning periods and areas may reduce the errors in mapping distribution of eggs of a single species. Egqs with a diameter of 1.20 to 1.59 mm, most probably of cod, and eggs with a diameter of 1.0 to 1.19 mm, probably of saithe, Norway pout or blue whiting, were most abundant. Highest densities were found off Møre and in the Lofoten-Vestfjorden area. Both categories of eggs were usually found in highest numbers during the second half of April. Eggs and larvae of blue whiting were recorded from Stad to Træna.
