Item Laguna Madre Project Quarterly Report - September 9, 1951 to December 31, 1951(Texas Game and Fish Commission, 1952) Miles, Dewey W.This report is the first of the present investigation known as Laguna Madre Project. The investigation covers the entire Laguna Madre from Corpus Christi to Port Isabel on the Texas Gulf Coast. The project is divided into three areas and each area is covered by a biologist. Mr. Ernest Simmons in the northern Laguna Madre covers the area from Corpus Christi to Yarborough Pass. Mr. Joseph Breuer covers the area comprising all of Baffin Bay and the waters south of the bay to the north end of the land lock. My area comprises that part of the Laguna Madre from the south end of the land lock to the town of Port Isabel. The respective areas are known as northern Laguna Madre, Baffin Bay, and southern Laguna Madre. It is our intention to correlate the findings of all three biologists into one conclusive paper at the termination of this project. This paper will attempt to answer many long sought questions regarding the high productivity of fish in the Laguna Madre.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 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 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 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 Report on Tagging at Eighth Pass(Texas Game and Fish Commission, 1952) Miles, Dewey W.No abstract available. Fish stock assessment of Eighth Pass in Mexico, 100 miles southwest of Port Isabel, Texas.
