Abstract

Brown and white shrimp were sampled twice each month at 9 sampling stations. This included 3 primary, 2 secondary and 4 tertiary bay stations. The first juvenile brown shrimp of the year were taken in the mid-April samples, 15 days later than in 1963. Shrimp as small as 25 mm were found in the May samples and again in June. In comparison with 1963, there was a slight decline in the brown shrimp catch per unit of effort. There was a corresponding decline in the commercial landings reported for the Corpus Christi Bay area. Juvenile white shrimp were first taken in the mid-June samples, about 30 days earlier than in 1963. This first wave of juveniles, ranging in size from 28 to 50 mm, was taken in Nueces Bay at a rate of about 20 per trawl sample. A peak of abundance was reached in October with 163.3 shrimp per unit of effort. White shrimp were more abundant in 1964 than in 1963. There was also a corresponding increase in rainfall in 1964.
