Feeding habits of several mass shrimp species in the Sea of Okhotsk

Feeding habits of several mass shrimp species in the Sea of Okhotsk Information on the qualitative and quantitative characteristics of the feeding habits of two pandal shrimp—the humpy shrimp (Pandalus goniurus) and the northern shrimp (Pandalus borealis) and one species of crangonids (Crangon communis) is submitted.

Abstract

Information on the qualitative and quantitative characteristics of the feeding habits of two pandal shrimp—the humpy shrimp (Pandalus goniurus) and the northern shrimp (Pandalus borealis) and one species of crangonids (Crangon communis) is submitted. The materials were collected in April–May 2006 and 2007 during complex surveys at West Kamchatka. The size and sex composition of the shrimp, as well as the composition of their food were analyzed. The food of all the considered species basically consisted of polychaetes, amphipods and, to a lesser extent, other shrimp. The daily ration (DR) of a shrimp with a body length of 40–60 mm was calculated for the first time—it was 7.9% of the body weight. The DR of a northern shrimp 61–80 mm in length was 5.8% of its body weight. Individuals of the third species, Crangon communis, generally did not feed.
