    Notes: Abstract.— Meiotic gynogens were produced using hybrid striped bass (♀ white bass, Morone chrysops, ×♂ striped bass, M. saxatilis) eggs and white perch M. americana UV-irradiated sperm. Diploidy of the fertilized eggs was restored by application of hydrostatic pressure, which induced retention of the second polar body. Use of white perch sperm provided an unmistakable marker for detection of a paternal genetic contribution. Two assays were developed using the polymerase chain reaction (PCR) to amplify specific regions of the Morone genome. Primers for gene amplification were developed based on the DNA sequence of the striped bass growth hormone gene (SB-GH) or an anonymous striped bass locus (SBI-10). Control experiments using DNA from the three Morone species demonstrated that gene amplification yielded species-specific patterns of DNA fragments for both of these loci. Therefore, any progeny with a paternal contribution of a set of white perch chromosomes could be identified. Using these assays, we demonstrated that greater than 75% of the progeny obtained from successful experiments were true gynogens. These striped bass hybrid gynogens will provide the basis for future efforts to calculate gene-centromere distances and to identify markers linked to specific traits of interest to aquaculture.

    Composition and Quality of Aquacultured Hybrid Striped Bass Fillets as Affected by Dietary Fatty Acids (1994)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Five groups of reciprocal cross hybrid striped bass were fed semipurified isocaloric diets containing varying concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Fatty acid compositions of the edible muscle tissue generally reflected the fatty acid contents of the diets with greater concentrations of DHA being accumulated compared to EPA. Descriptive sensory evaluation of cooked fish fed diets containing at least 0.50% EPA and 0.24% DHA showed a significant increase in fishy flavor intensity compared to cooked fish fed diets containing trace amounts of these n-3 fatty acids. Hybrid striped bass can be a good source of nutritional n-3 fatty acids when sufficient quantities are incorporated into their diet.

    Comparative Stress Dynamics of Brood Stock Striped Bass Morone saxatilis Associated with Two Capture Techniques (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the World Aquaculture Society 23 (1992), S. 0

    Notes: Mature striped bass (Morone saxatilis) were collected from the spawning reaches of the Choptank River, Maryland for the purpose of evaluating stress effects associated with capture. Two commonly used capture devices were evaluated—gillnetting and electrofishing. Results indicated that stress, as measured by changes in plasma corticosteroid and chloride concentrations, was significantly lower and recovery time quicker in those fish captured by electrofishing compared to gillnetting. By the end of the study period (48 h), those fish captured by electrofishing had recovered from the initial capture shock as evidenced by corticosteroid levels returning to near baseline levels. Conversely, at 48 h post-capture, those fish captured by gillnetting exhibited severe hypochloremia and elevated corticosteroid levels approaching that of the initial stress associated with capture.

    Acceptance and Consumption of Food by Striped Bass and Hybrid Larvae (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the World Aquaculture Society 21 (1990), S. 0 
    Details
    ISSN: 1749-7345

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Food acceptance, consumption and weaning times were investigated for striped bass (Morone saxatilis) and hybrid striped bass (M. saxatilis×M. chrysops) larvae. Experimental treatments consisted of: control groups of striped bass (SC) and hybrids (HC) fed Artemia nauplii; hybrids fed formula food (HF); and hybrids weaned from Artemia nauplii to formula food at 11–15 days (HF1), and 18–22 days (HF2) posthatch. The formula diet did not support growth and resulted in total mortality of the HF hybrids by the third week posthatch. HF1 fish had significantly slower growth and lower survival than HF2 of HC. The HF2, HC and SC groups had similar growth and survival, which indicated no heterosis in hybrids. There were no differences in Artemia nauplii consumption by the SC and HC groups. Daily consumption increased exponentially for both groups (0.8 to 50–60 cal/day/larva between 7 and 30 days posthatch). Weight specific consumption (WSC) decreased initially and then increased for both groups. A mean WSC of 58% (range of 24–83%) was found for the combined SC and HC groups. Food conversion ratio, growth efficiency, caloric efficiency, and productive protein values were similar for striped bass and hybrid larvae.
