Notes on distribution, size, and ovarian development of some penaeid shrimps in the northwestern Gulf of Mexico 1961-62.

Between January 1961 and December 1962, shrimp were taken monthly using commercial shrimping gear at a series of offshore stations in the northwestern Gulf of Mexico. The general distribution of nine species not presently utilized commercially was determined. The relative abundance of these shrimp in various depths and areas are noted. General seasonal changes in catch per hour were reported for the more abundant species, and size distributions for each species were presented. Examination of ovaries revealed ripe females in nearly every month at all depths occupied by a species. Seasonal increases in the percentages of ripe females were noted for some species.
