Replacement of Fish Meal with Poultry By-Product Meal as a Protein Source in Sunshine Bass, Morone Chyrsops X Morone Saxatilis , Diets
(2008-09-09)
The sunshine bass Morone chrysops x Morone saxatilis has become an important fish to aquaculture in the United States favored as both a sport fish and a food fish. As with many cultured species, feed often accounts for ...
Developing a Long-Term Monitoring Protocol for the Pygmy Sculpin (Cottus paulus), a Spring Dwelling Imperiled Species
(2014-05-14)
Long-term monitoring protocols require adequate levels of precision in order to detect temporal changes in abundance or density. However, the ability to detect changes can be reduced by sampling variation, seasonal ...
Novel experimental technique to confirm fish hosts for “large river mussels”
(2014-07-02)
Unionid mussels are declining in North America. The larval stage (glochidium) represents a life-history bottleneck because glochidia are parasitic and require an appropriate fish host. However, appropriate fish host species ...
Differences in oxygen consumption and critical oxygen levels of five stream fishes
(2013-11-08)
Metabolic rate represents an integrated measure of a fish’s physiology, particularly as it relates to stressors. A metric that is commonly used to determine the hypoxia tolerance of fishes is the determination of animal ...
Identification and analysis of recently duplicated genes in channel catfish (Ictalurus punctatus) genome
(2013-12-04)
Gene duplication is an important source of genetic innovation and structure and usually associated to the lineage-specific adaptive trait during evolution, such as genes related to immunity, development and reproduction. ...
Study and evaluation of bigano snail (Stramonita haemastoma) as a marketable seafood species
(2013-12-03)
To evaluate whether a species is potentially edible, marketable and sustainable, we need to answer quite a few questions about what, why, where, who, when and how. This dissertation consists of five chapters. The basic ...
Shifting Relationships Between Crayfish and Symbiotic Worms in Surface Water and Subterranean Environments
(2013-08-22)
Branchiobdellidans are small annelids (Clitellata) that have neutral, positive, and negative effects on stream crayfishes. Host effects are context dependent, with positive effects (increased survivorship and growth) ...
Evaluation of soybean meal from selected cultivars of soybeans for use in practical diets for L. vannamei
(2013-11-08)
This study was designed to evaluate the efficacy of twelve sources of soybean meal (SBM), which included new soy varieties in practical feed formulation for Pacific white shrimp, Litopenaeus vannamei, using both digestibility ...
Effect of Ammonia Nitrogen on Production and Haemolymph of Pacific White Shrimp (Litopenaeus vannamei) Cultured in Low Salinity Ponds in Greene County, Alabama
(2014-07-24)
Water temperature, pH, and concentration of total ammonia nitrogen were measured on 12 sampling date in summer 2013 in eight shrimp ponds on an inland, low-salinity shrimp farm in Alabama. Shrimp haemolymph samples also ...
Evaluation of production characteristics of four strains of Nile tilapia Oreochromis niloticus and a red variety under two sets of intensive culture conditions
(2011-11-22)
The wide native range of Nile tilapia O. niloticus offers the possibility of genetic diversity within the species and variation among populations as to their suitability for aquaculture. But only a few populations have ...
