    Data on salp by-catch and green krill were analyzed based on Logbook data of Japanese krill trawlers. Inter-annual and seasonal variability of the timing, duration and strength of salp bloom were indicated. Salp by-catch and occurrence of green krill seemed to show reverse correlation, implying the competition for phytoplankton between krill and salps.
