Spawning populations.

Abstract

During 1961, 17 cruises were made in the area between Galveston, Texas, and Cameron, Louisiana. At each of the 11 stations in the area, a 45-foot shrimp trawl was towed for 1 hour. Penaeid shrimps taken were counted, sexed, and measured, and predetermined numbers of females of each species were dissected to obtain samples of ovary tissue.
