A difference in seasonal peaks of abundance was noted in 1961. Cooler spring weather in 1961 is possibly a factor accounting for the later peaks that year. The efficiency of the twenty-foot otter trawl is believed to be greater than that of the ten-foot otter trawl by a factor larger than two.en-USforage fishesfish populationsspecies compositionTechnical Report
