Abstract |
King mackerel, Scomberomorus cavalla (1,968) caught by hook and line off Grand Isle, Louisiana, were tagged with internal anchor tags and released between 1983 and 1985. Fifty-five tags were recovered, providing an overall return rate of 2.8 percent. King mackerel tagged in winter were returned in every month of the year, but always from the Grand Isle area or westward as far as Veracruz, Mexico. All but one summer-tagged fish were returned in winter months from the Grand Isle area, Key West, Florida, or from Mexico. Winter-tagged fish were mostly large and mostly remained in the northwest Gulf. Summer-tagged fish tended to stay in the northwest Gulf if they they were large, or migrated to south Florida or Mexico if they were small. The data indicate that the northwest Gulf maintains resident large king mackerel year round, and that these fish mix with smaller migrants from south Florida and Mexico to some degree in warmer months. |
