Item Hydrographic and Meteorological Study of the Matagorda Bay System - Analysis of Populations of Sports and Commercial Fin-Fish and of Factors Which Affect These Populations in the Coastal Bays of Texas(Texas Parks and Wildlife Department, 1965) Munro, George J.; King, B. D., IIISalinities and the Matagorda Bay System increased in 1964 and rainfall was slightly below normal. Water temperatures were similar to those found in 1963. A hard freeze occurred in mid-January.Item Population Studies of the Sports and Commercial Fin-Fish of the Matagorda Bay System - Analysis of Populations of Sports and Commercial Fin-Fish and of Factors Which Affect These Populations in the Coastal Bays of Texas(Texas Parks and Wildlife Department, 1965) Munro, George J.Collections were made at fixed stations with trammel net, 60- foot seine and bar-seine to obtain information on adult and juvenile game fish. The juvenile stations at the Matagorda Club on Matagorda Peninsula and at Powderhorn Lake generally produced more game fish per acre than the other stations. Adult game fish were found to be more abundant in Powderhorn Lake and Carancahua Bay than they were in Turtle Bay or Coon Island Bay. Fish tags returned in this study were used in an effort to estimate natural mortality and fishing pressure.Item Study of the Juvenile Shrimp Populations of the Matagorda Bay System-Study of the Texas Shrimp Populations(Texas Parks and Wildlife Department, 1965) Munro, George J.Small brown shrimps Penaeus aztecus, were found at tertiary bay in April. Emigration began in June when the shrimp were about 81 mm long. A second wave was observed in August. Juvenile white shrimp, Penaeus setiferus,, appeared in the samples in early June, A second, but smaller, wave was observed in September. Shrimp caught in the 20-foot trawl samples were smaller than shrimp caught by commercial trawls. Thus data based on 20-foot trawl catches were considered invalid. The 1964 commercial brown shrimp catch, in the bay system increased 12 per cent over 1963. White shrimp landings increased. 60 per cent over 1963.Item Study on the Effects of the Closure of the Brown Cedar Cut - Analysis of Populations of Sports and Commercial Fin-Fish and of Factors Which Affect These Populations in the Coastal Bays of Texas(Texas Parks and Wildlife Department, 1965) Munro, George J.Brown Cedar Cut, a natural pass into East Matagorda Bay, closed in March 1964. A study was immediately begun to determine the effects of this closing on the fisheries of East Matagorda Bay. White shrimp, Penaeus setiferus; brown shrimp, P. aztecus; speckled trout, Cyniscion nebulosus; redfish, Sciaenops ocellata; black drum, Pogonias cromis; souther flounder, Paralichthys lethostigmus; sheepshead, Archosargus probatocephalus; and forage species were found in the study area.
