Feeding and feed-processing by red drum (Sciaenops ocellatus) fed natural and formluated diets
(Texas A&M University, 2003)
Experiments with juvenile red drum, Sciaenops ocellatus, estimated 1) digestibility, 2) feed consumption and growth, and 3) gastric evacuation rate (GER) for two diets: shrimp tail-meat ("Shrimp"), representing natural ...
Evaluation of various sulphur amino acid compounds in the diet of red drum, Sciaenops ocellatus
(Texas A&M University, 2003)
Refinement of diet formulations to enhance the efficiency of red drum production continues to be pursued. Based on previous studies, the sulfur amino acid (SAA) requirement of red drum for methionine plus cystine appears ...
Occurrence, behavior and genetic diversity of bowhead whales in the Western Sea of Okhotsk, Russia
(Texas A&M University, 2002)
The Okhotsk Sea (OS) stock of bowhead whales was severely reduced by commercial whaling in the late 19th century and again by illegal Soviet pelagic whaling in the 1960s. Estimates of the population prior to exploitation ...
A model simulation of white-winged dove population dynamics in the Tamaulipan Biotic Province
(Texas A&M University, 2002)
I present the development, evaluation, and sensitivity analysis of a simulation model representing two components of population dynamics-natality and mortality-for the white-winged dove (Zenaida asiatica asiatica; WWDO). ...
Histological evaluation of pearl-sac development in the Concho Pearly Mussel (Cyrtonaias tampicoens)
(Texas A&M University, 2002)
The purpose of this project was to assess the wound repair properties and epithelial cell proliferation in the processes necessary to develop a pearl-sac in the mantle of the Concho Pearly Mussel (Uniodidea: Cyrtonaias ...
The influence of environmental factors on spatial and temporal variation of fish assemblages in the lower Brazos River, Texas
(Texas A&M University, 2003)
Large floodplain rivers are spatially heterogeneous and temporally dynamic ecosystems. However, few studies have quantified the variation or species-environment relationships of fish assemblages in the main-channel of ...
Habitat use and occurrence of the bull shark (Carcharhinus leucas) near the Sabine Pass inlet of Texas and Louisiana
(Texas A&M University, 2000)
The role of nearshore Gulf of Mexico habitats adjacent to Sabine Pass, a tidal inlet forming the southernmost border between Texas and Louisiana, in bull shark (Carcharhinus leucas) life history as well as the impact of ...
Three-dimensional photogrammetry as a tool for assessing morphometrics and estimating body mass of Steller sea lions
(Texas A&M University, 2000)
A technique was developed to indirectly assess morphometrics and to estimate body mass of Steller sea lions (Eumetopias jubatus using three- dimensional (3D) photogrammetry. 3D computer wireframes of thirty-five Steller ...
The relationship between ownership fragmentation and landscape structure in Bastrop County, Texas
(Texas A&M University, 2002)
Few formalized studies have documented the relationships between land ownership fragmentation and landscape structure. The increasing demand for rural land, especially near urban areas, is causing ownership fragmentation. ...
The occurrence, habitat use, and behavior of sharks and rays associating with topographic highs in the northwestern Gulf of Mexico
(Texas A&M University, 2001)
Some wide-ranging elasmobranch species are frequently reported to occur at topographic highs, which are topographic prominences that rise from the sea floor and provide significant positive and structural relief in an ...
