| Summary: | and along the southeast coast of the United States. Stable and tag and recovery research suggest the Gulf of Mexico is as two stocks, an Atlantic migratory group and a Gulf of boundaries for the stocks are uncertain. Previous genetic comprised of two stocks of each species. King and Spanish conducted on collagen extracted from the dorsal fin spines. determine isotopic trends and isotopic ranges within the distinct groups for this species. Dorsal fin spines were divided into sections in order to mackerel made it difficult to differentiate isotopically mackerel were collected at ten sites in the Gulf of Mexico Mexican king mackerel. Limited sample collection of Spanish Mexico is unknown. Presently, both species are each treated Mexico migratory group. There is evidence for existence of nitrogen (81,5N) and carbon (613C) isotope measurements were significantly different, in nitrogen, from the Florida and Spanish mackerel (S. maculatus) that exist in the Gulf of spine. Stable nitrogen isotope results suggest that at least The northwestern Gulf of Mexico king mackerel were The number of stocks of king (Scomberomorus cavalla) and two groups of king mackerel exist within the Gulf of Mexico. two stocks of these species within the Gulf of Mexico, but |
