A euphusiid, Euphausia pacifica, as an important food source to demersal fishes in the eastern Korean water

초록

A large amount of euphausiids, Euphausia pacifica, is found to be distributed in the estern Korean water adjacent to Uljin, which often aggregates near the bottom in the depth range of 100-200m approximately. During the studies on euphausiids, we examined gut contents of several species of fishes destributed around the studied area to partially understand their ecological roles as a food source. Among the fishes caught in fishery nets set close to the region where euphausiids, aggregations were observed, only two fish species, arabesque greenling and spinyhead sculpin were available with sufficient amounts for data in the collection of Oct 2002, Mar 2003 and Jun 2003, while other species captured with small amounts also often included euphausiids in their guts.
