Western North Atlantic Coastal Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Stock Structure of the Coastal Morphotype
A. Latitudinal distribution and structure along the coast The coastal morphotype is continuously distributed along the Atlantic coast south of Long Island, around peninsula Florida and along the Gulf of Mexico coast. On the basis of differences in mtDNA haplotype frequencies, however, Curry (1997) c...
