Selectivity of Gill Nets on Spanish Mackerel, 'Scomberomorus maculatus', King Mackerel, 'S. cavalla', and Bluefish, 'Pomatomus saltatrix'

摘要

Information from experimental settings of gill nets reported in the literature and data taken from commercial fishermen in Florida from 1973 to 1981 were used to analyze gill net selection on Spanish mackerel, Scomberomorus maculatus, king mackerel, S. cavalla, and bluefish, Pomatomus saltatrix from Florida and Serra Spanish mackerel, S. braziliensis, from Brazil. The objectives of this study were to show relations between mesh sizes and sizes of netted Spanish mackerel, bluefish, and king mackerel and girth-length relations for each species.
