Report presenting the results of a study on the movement patterns of blue crabs in Trinity Bay.

Report detailing the results of a study comparing the catch of eastern market oysters in .5 and 1 minute tows to determine if the interpretation of the data is affected.

Report on channel and blue catfish being stocked in Texas waters, including the techniques used to stock these fish.

Report on the results of a study examining the efficacy of immersing striped bass fingerlings in a solution of tetracycline as a marking method in order to gather accurate statistics on the survival rate of striped bass fingerlings.

The report includes annual pressure and landings estimates for a private boat, party boat and head boat fishing in Texas bays and passes.

Report on dealers reporting saltwater landings in Texas and compliance with the self-reporting law.

Report documenting statistics related to commercial fishery landings and ex-vessel value of statistics of finfish and shellfish harvested.

Report documenting statistics related to commercial fishery landings and ex-vessel value statistics of finfish and shellfish harvested from Texas bays and the Gulf of Mexico off Texas.

Report on study of spotted seatrout, including spawning trials, water quality influence, survival rates, and returns.

Report on the procedures used by Texas Parks and Wildlife Department to culture of red drum fingerlings for use in supplementing the stock in Texas water ways.

Abstract: In 1989, 82,139,452 red drum (Sciaenops ocellatus) fry and fingerlings were stocked into Texas bays. Matagorda and East Matagorda Bay received 74,313 fry and fingerling spotted seatrout (Cynoscion nebulosus). Galveston Bay received 5,049,000 striped bass (Morone saxatilis) fry and 349,240 fingerlings.

Abstract: In 1990, 183,896,448 red drum (Sciaenops ocellatus) fry and fingerlings were stocked into Texas bays. Upper Laguna Madre received 34,887 fingerling spotted seatrout (Cynoscion nebulosus). Galveston Bay and Sabine Lake received 337,880 striped bass (Morone saxatilis) fingerlings.

Report examining cultured paddlefish, their muscle proteins, and their eyes to see if protein electrophoresis is a useful way to study stock dynamics. The report indicates this is an inadequate means of study.

Report detailing studies on the white shrimp of Texas, including catch rates, mean length, and size comparison with past years.

Abstract: Eastern oysters (Crassostrea virginica) were collected from South Bay, Texas and induced to spawn in the laboratory. These oysters were conditioned for 12 weeks on continuous flow using Matagorda Bay water. Spawning procedures used resulted in approximately two million larvae. Results indicate that Eastern oysters from South Bay, Texas can be successfully spawned in the laboratory using established procedures.

Report on the results of a study to test whether Eastern Oysters could be induced to spawn out of season in Texas. The study concluded that successful spawning of Eastern oysters on a year round basis is possible using continuous flow procedures.

Report on study of commercial saltwater finfish fishermen, including their seine tag purchases, trotline tag purchases, and the counties these were bought in.

Abstract: Available literature concerning purse seine fisheries was reviewed. Literature was selected for this report if 1) it presented information that provided insight into the history and long-term trends in a fishery and 2) it presented information on purse seines unique to a fishery. Information found in the reviewed literature revealed that purse seines are a highly efficient fishing gear and without adequate regulation are potentially damaging to targeted fish populations.

Report examining the extent of predation on blue tilapia by catfish in Victor Bruanig and Calaveras reservoirs.

Abstract: Since 1971, approximately thirty-eight million Florida largemouth bass (Micropterus salmoides floridanus) were stocked into Texas waters. Fish for stocking were cultured using techniques described in this manual.

Report documenting statistics related to commercial fishery landings including trends in quantities and values of various species.

Report examining the thermal tolerance of three age groups of paddlefish including the methodology of the study and the experimental results of the study.

The objective of the report is to summarize catches of non-reef oyster samples collected in upper and lower Laguna Madre during January 1986- December 1988.
