Seasonality and midscale spatial effects on Cichla ecology and fish species diversity in a neotropical floodplain river
(Texas A&M University, 1995)
The influence of seasonal fluctuations in water levels on tropical fish species from fluvial environments was evaluated by comparing the ecology of resident piscivores and habitat use of prey fish within a floodplain river. ...
Ecology of the river dolphin, Inia geoffrensis, in the Cinaruco River, Venezuela
(Texas A&M University, 1995)
The Cinaruco River is a tributary of the Orinoco River, and forms the southern boundary of Venezuela's newest national park, Santos Luzardo. Like other rivers of this region, the Cinaruco River undergoes an extreme seasonal ...
Waste treatment capacity of raft hydroponic lettuce production in an integrated fish culture system and the contribution of lettuce to treatment capacity
(Texas A&M University, 1995)
Two experiments were conducted to determine: 1.) the waste treatment capacity of raft hydroponic lettuce production in an integrated fish culture system and 2.) the contribution of lettuce plants, Lactuca saliva, cv. Paris ...
Spatial and temporal variation in fish assemblage structure at Village Creek
(Texas A&M University, 1995)
Fish assemblages were sampled seasonally at Village Creek, a blackwater tributary of the Neches River in Hardin County, Texas. Forty four fish species were captured at Village Creek from diverse aquatic mesohabitats, (e.g., ...
Fishery ecological survey of natural coastal lakes of Benin, West Africa
(Texas A&M University, 1995)
Fish assemblages were sampled and water physicochemistry was evaluated in Lake Nokoue and Lagoon Toho-Todougba in southern Benin. Various biological parameters (species richness, species diversity, abundance, relative ...
A survey of serum antibody titers to brucellosis and pseudorabies in feral swine in Texas
(Texas A&M University, 1995)
Serum samples were collected from 500 feral swine in 34 Texas counties. Swine Brucellosis (SB) testing with the standard brucellosis card test (CT) and the particle concentration fluorescence immunoassay (PCFIA) test, and ...
Ecology of large piscivorous fishes in Guri Reservoir, Venezuela, with notes on fish community structure
(Texas A&M University, 1995)
Venezuela's growing human population is accompanied by a growing need for electricity which has largely been met with hydroelectric power, and yet the full effects of river impoundment on river ecosystems are not known. ...
Composition, structure, and habitat associations of fish assemblages of the Dolan Falls Preserve
(Texas A&M University, 1995)
The composition and stability of fish assemblages at eight stations of the Devil's River at the Texas Nature Conservancy Preserve were quantified in four surveys over a one-year period. Data were analyzed to explore natural ...
Use of stable isotopes to assess king and Spanish mackerel groups
(Texas A&M University, 1995)
The number of stocks of king (Scomberomorus cavalla) and Spanish mackerel (S. maculatus) that exist in the Gulf of Mexico is unknown. Presently, both species are each treated as two stocks, an Atlantic migratory group and ...
An integrated study of dietary lipid manipulation and thermal-refuge technology for overwintering red drum (Sciaenops ocellatus) in outdoor ponds
(Texas A&M University, 1995)
A commercial diet containing 10% lipid and an experimental diet consisting of the commercial diet with additional menhaden oil to provide 14.5% lipid were fed to separate groups of juvenile (100 g) red drum (Sciaenops ...
