Item Natural history and conservation of the redfish and other commercial sciaenids on the Texas coast.(1928) Pearson, J.C.; Manuscript submitted to Bulletin of the Bureau of FisheriesThe natural histories of the three leading foodfishes of coastal Texas- the redfish (Sciaenops ocellata), the black drum (Pogonias cromis), and the spotted seatrout (Cynoscion nebulosus)- have been little understood in any section the distribution of these species. Along the Texas coast serious debates often arise as to the habits of the redfish, drum and spotted trout, with reference to the location of young and adult fish.Item Construction and Operation of Lobster Fishing Gear(United States Department of the Interior, Fish and Wildlife Service, Bureau of Commercial Fishes, 1944-07) Firth, Frank E.No abstract available.Item Methods of Net Mending - New England(United States Department of the Interior Fish and Wildlife Service Bureau of Commercial Fisheries, 1947-05) Knake, Boris O.No abstract available.Item Annotated bibliography for the student of Texas fishes and fisheries with material on the Gulf of Mexico and the Caribbean Sea.(J.L. Baughman, 1948) Baughman, J.L.;A mimeographed annotated bibliography of 965 references from about 1800 to 1947 of the occurrence, stocking, sport and commercial fishing, natural history, etc., of the fish, oysters, crabs, shrimp, turtles, frogs, whales, etc., of Texan lakes and Gulf of Mexico coasts, principally Texas. Comments range from a few words to 3 pages, with quotations from some surveys reaching 30 pages. The value of the compilation is limited by the absence of an index and the listing in alphabetical order by author.Item Fish Trap Investigation(Texas Game, Fish and Oyster Commission, 1950) Simmons, Ernest G.For a number of years a clamor has been raised along the Texas coast that the lack of natural passes from the Gulf of Mexico to the bay areas is the limiting factor of the population of these bays. It has been believed by many that more passes should be cut through Mustang Island, Padre Island, St. Joseph's Island and Matagorda Island. Little heed has been given the fact that all attempts to dredge such channels have been dismal failures unless expensive jettying has accompanied the dredging operation. Silting and hurricane action inevitably nullify the effort. Nevertheless the theory still holds that the various species of marine life utilize the existing passes to repopulate the bays. It was primarily to test this theory that a fish trap was installed in Cedar Bayou. There were several other reasons for the installing of this trap, reason which may be summarized briefly.Item Blue Crab Investigation, 1949-50(Texas Game and Fish Commission, 1950) Daugherty, F. M., Jr.Basically, the blue crab investigation for 1949-50 was conducted in a manner similar to that employed in 1947-48 and 1948-49 (Daugherty, 1948, 1949). Objectives were essentially this same, however, methods of collection were different. Crab pots and the fish traps in Cedar Bayou were used extensively in sampling. Several new stations were established and the original stations were checked only when it was deemed advisable. Deviation from the exclusive use of permanent stations and accentuation on new and varied areas gave gratifying results. A broad program was originally planned for 1949-50, but as the year progressed work was automatically channeled along the lines of spawning, hatching, and migration. Emphasis was placed on the collection of crabs infested with the Rhizocephalid, Loxothylacus texanus. The Marine Laboratory was fortunate in having Dr. Edward G. Reinhard of Catholic University, Washington, D.C., work on this phase of the crab problem during the summer of 1950. Fishing experiments using crab pots and trotlines had been planned, however, this work did not develop in light of increasing demands of the spawning, hatching, and migration portions of the investigation. It was possible, even so, to formulate hypothetical catch expectancies based on routine crab pot sampling.Item Life Histories of the Spotted Sea Trout, Cynoscion nebulosus, and the Redfish, Sciaenops ocellatus(Texas Game and Fish Commission, 1950) Miles, Dewey W.The study of the life histories of the trout and redfish was initiated after some careful consideration of original ground work on these fish by John C. Pearson from April, 1926, to June, 1927. The study was proposed by the Copano Research Foundation as a cooperative project between themselves and the Marine Laboratory of the Texas Game, Fish and Oyster Commission. Enough credit cannot be given Mr. Pearson for his splendid work which made possible the basis of the present study.Item Oyster Investigation for the Fiscal Year 1949-1950(Texas Game, Fish and Oyster Commission, 1950) Baker, B. B., Jr.This investigation is a study of the environmental features which will determine the suitability of areas for production of market oysters. During the past three years emphasis has been placed upon studies of the effects of environment and ecological relationships involved in the transplanting of seed oysters. Five bays, (Aransas, Copano, Mesquite, Carlos, and Redfish) in the vicinity of Rockport have been utilized in the establishment of one acre test plots. This period emphasis has been mainly on a preliminary survey of the spawning and setting activities in the area, including some data on spat size and growth. Data was obtained on oyster quality and a monthly series of the three quality factors has begun at the close of the period. Routine collection of data on hydrography and plankton for correlation with oyster quality and productivity was continued.Item Oyster Investigation Quarterly Report - April 1, 1951 to July 1, 1951(Texas Game and Fish Commission, 1951) Parker, Robert H.This investigation has been designed to search out the reasons for the decline in oyster production during the past few decades, and to find means of rehabilitating the industry on the Texas coast. Experiments have been carried out to find new methods for increasing the size and rate of growth of oysters. A preliminary survey of the local bays was made for a good commercial source of edible clams.Item Life Histories of the Trout and Redfish Quarterly Report - April 1, 1951 to June 30, 1951(Texas Game and Fish Commission, 1951) Miles, Dewey W.The quarterly period of April, May, and June, 1951, was spent in the examination of this year's spawning sea-trout and further experimentation on the fertilizing of Copano Lake. Previous collections of trout ovaries and testes which had been preserved in Bouin's solution were embedded in paraffin, sectioned, and mounted for photographical purposes and further analysis of the trout and redfish sexual development. Some fish tagging was carried out in the field on trout of the second year class. Experimentation was begun on the analysis of age groups and year classes by the otolith method of determination.Item Survey of the Effects of a Natural Pass on Fish Populations Quarterly Report - October 1, 1950 to December 31, 1950(Texas Game and Fish Commission, 1951) Simmons, Ernest G.During the previous months of the year it was observed that the south trap was not successful in taking sea trout (Cynoscion nebulosus) and redfish (Sciaenops ocellatus). These species would often move up to the trap but would not enter. It was decided to build a spiral trap to combat this situation.Item Survey of the Effects of a Natural Pass on Fish Population Quarterly Report - January 1, 1951 to March 31, 1951(Texas Game and Fish Commission, 1951) Simmons, Ernest G.The primary objectives of the fish trap have been stated in previous reports. Determination of the role played by a natural pass is the key objective.Item Quarterly Report - January 1, 1951 to March 31, 1951(Texas Game and Fish Commission, 1951) Miles, Dewey W.The quarterly period of January, February, and March, 1951, was spent searching for adult sea-trout of the year class I and older. Ovaries and testes from spent, maturing, and mature sea-trout were collected in the field and preserved in Bouin's solution for histological sectioning in order to make late comparisons of developmental stages.Item Quarterly Report - April 1, 1951 to June 30, 1951(Texas Game and Fish Commission, 1951) Breuer, Joseph P.The months of April and May were spent in carrying out various miscellaneous projects at the laboratory and in becoming familiar with the Laguna Madre and the various oceanographic methods and techniques in preparation for the project now underway. On May 11, 1951, field headquarters were set up at Caroline Beach (Loyola Beach) on Baffin Bay from which an ecological survey of the Baffin Bay area will be conducted. Fish tagging operations will also be carried out. This project is part of the Laguna Madre program now underway.Item Life History of the Sea Trout, Redfish and Flounder(Texas Game and Fish Commission, 1951) Miles, Dewey W.The quarterly period of October, November, and December, 1950, was spent tagging trout and redfish and obtaining adult individuals for sex, maturity, and age determination. An intensive search for the eggs, larvae, and post larval forms of the redfish (Sciaenops ocellatus) was made from September 15, 1950 to December 1, 1950. Concentration for most of the quarter period was upon the collection of mature trout and redfish for sexual examination.Item Oyster Investigation Quarterly Report - January 1, 1951 to March 31, 1951(Texas Game and Fish Commission, 1951) Parker, Robert H.This investigation is designed to search out the reasons for oyster mortality in the past decade, and to find means of rehabilitating the industry on the Texas coast. A survey is being made of both live and dead oyster reefs in the coastal waters.Item Survey of the Effects of a Natural Pass on Fish Populations Quarterly Report - April 1, 1951 to June 30, 1951(Texas Game and Fish Commission, 1951) Simmons, Ernest G.The primary objectives of the fish trap have been listed in previous reports. Briefly, the trap was installed to determine the what, when, where and why of the movement of fish and other organisms.Item Shrimp Investigation Quarterly Report - November 1, 1950 to December 31, 1950(Texas Game and Fish Commission, 1951-01) McRay, E. D., Jr.The current shrimp investigation was initiated 26 November 1950. The purpose of the project is to conduct an investigation of the off-shore waters of the Texas coast with a view toward facilitating both the present work of the shrimp industry and its future expansion. The waters to be studied include those which are now being utilized by the commercial shrimpers as well as other waters which might either support an expansion of the industry or supplement any possible decrease in the future production of the present shrimping grounds. A secondary purpose of the study is to determine any trait or characteristic of the shrimp which could be utilized by the shrimp fishermen as a basis for locating or predicting the presence of significant concentrations of shrimp.Item Blue Crab Investigation Quarterly Report - October 1, 1950 to December 22, 1950(Texas Game and Fish Commission, 1951-01) Daugherty, F. M., Jr.The blue crab investigation is concerned with the life history in Texas waters, migration patterns, shedding grounds, crab parasites, and fishing methods.Item Oyster Investigation Quarterly Report - October 1, 1950 to December 31, 1950(Texas Game and Fish Commission, 1951-01) Parker, Robert H.This investigation is now being conducted for the purpose of rehabilitating the oyster industry in Texas, and to promote or determine the advisability of commercial oyster cultivation. Information is also being obtained as to the effects of environment upon growth, mortality, and spawning of Ostrea virginica Gmelin.
