| Abstract |
Whole otoliths of 1,098 king mackerel, Scomberomorus cavalla, 410-1,802 mm fork length (FL) were examined. The fish were sampled from recreational and commercial fisheries operating in the Gulf of Mexico from Key West, Fl., to the Yucatan Peninsula, Mex., from 1980 through 1985. Most fish were collected off Key West, Northwest Florida, and Texas. The oldest fish was 14 years old and measured 1,802 mm FL. Rings formed on most otoliths during the late winter through spring (February-May) and are thus considered to be true annual marks. Back-calculated mean lengths of 947 fish ranged from 420 mm at age 1 to 1,269 mm FL at age 14. Females live longer and attain larger sizes than males. The von Bertalanffy growth equations for both sexes combined, for females, and for males, are formulated. King mackerel are fully recruited to the gillnet and purse-seine fisheries of south Florida at age 2, to the recreational hook and line fishery off northwest Florida at ages 1 or 2, and to the Texas recreational hook and line fishery at ages 2, or 3. |
