King (Scomberomorus cavalia) and Spanish (Scomberomorus maculatus) mackerel migration and stock assessment study in the southern Gulf of Mexico. 1993 quarter V (January 1 - March 31, 1994) report.

Abstract

This is the quarter V report of a project conducted from January 1 - March 31, 1994 and describes the results of a study that was undertaken as part of an attempt to understand the migration and stock identity of the king and Spanish mackerel in the Gulf of Mexico. The goal was to report movement and migration of the mackerel, followed by length/frequency distributions and catch per unit efforts (CPUE) information, and to collect otoliths for stock assessment at specific Mexican locations. These locations were chosen so that the tagging effort would correspond with mackerel migration patterns off Mexico. During quarter V, work was concentrated off the state of Yucatan.
