Size and density of krill layers fished by a Japanese trawler in the waters north of Livingston Island in January 1988
Abstract / Description:
The size and density of fishable krill layers in the northern waters of Livingston Island were determined during the co-operative survey carried out by RV Kaiyo Maru and a Japanese trawler. The mean values of layer length, thickness and surface density were 3.25 km, 13.3 m and 228.0 g wet weight/m2, respectively. The krill layers fished by the trawler during the co-operative survey were 44.5 times longer and 2.7 times thicker but 25% less dense than the typical swarms encountered during FIBEX surveys.
