“…In that study, the DOM Striped Bass grew faster and had lower feed conversion ratios than most wild strains up to 1 year of age, but they did not maintain their growth advantage by the end of the second grow‐out year (24 months). The findings of the current study were consistent with those of Kenter et al (2018), as the DOM fish were generally larger in the treatment requiring the shortest duration to market size (large grade), but wild‐strain HSB achieved greater weights when culture exceeded 14 months. The reduced growth performance in recirculating systems during extended production times may reflect the persistence of genetic effects from slower‐growing Striped Bass strains included in the broodstock collapse described above.…”

“…Growth performance in recirculating systems for the parental strains used to produce sunshine bass in this study was previously documented by Kenter et al (2018). In that study, the DOM Striped Bass grew faster and had lower feed conversion ratios than most wild strains up to 1 year of age, but they did not maintain their growth advantage by the end of the second grow‐out year (24 months).…”

“…Broodfish acquisition.-Fingerling Striped Bass, which were bred in captivity during the natural (spring) spawning seasons at state and federal hatcheries in Virginia (VA strain), South Carolina (SC strain), Florida (FL strain), and Texas (TX strain), were transported to the Ritzman Aquaculture Laboratory, University of New Hampshire (UNH), Durham, and grown communally for 2 years in recirculating systems as previously described by Kenter et al (2018). The PIT-tagged fish were transported to North Carolina State University's Pamlico Aquaculture Field Laboratory (PAFL), Aurora, and were grown for an additional year in flow-through culture tanks (38,433 L) with well water.…”

“…Hybrid Striped Bass are poised for genetic improvement with well‐established husbandry protocols (Harrell et al 1990; Hodson 1995) and substantial recent advances in genetic/genomic resources (Reading et al 2012; Li et al 2014; Abdelrahman et al 2017; Fuller et al 2018; Zhao et al 2019). Strain‐specific differences in growth performance have been documented in Striped Bass (Jacobs et al 1999; Woods 2001; Kenter et al 2018), heritability estimates for production traits have been calculated at different life stages in hybrid offspring (Wang et al 2006; Lochmann and Goodwin 2015), and differences in weight and carcass yield were demonstrated in HSB produced using White Bass dams from three geographic strains (Kohler et al 2001). No studies, however, have examined differences originating from sires.…”

Paternal Strain Effects on Growth and Body Shape in Hybrid Striped Bass (White Bass ♀ × Striped Bass ♂)

The farming of hybrid Striped Bass (HSB; White Bass Morone chrysops ♀ × Striped Bass Morone saxatilis ♂) has been an established aquaculture industry in the United States for decades, but high production costs associated with performance variability remain a significant problem. To investigate the paternal effects on hybrid performance, Striped Bass males from Virginia, South Carolina, Florida, Texas and a fifth-generation domestic strain selected for growth were used as sires in a half-sibling, hybrid growth study. Eggs from individual White Bass (n = 11) were divided equally and fertilized with the fresh sperm from different Striped Bass sires (n = 18) to produce 53 hybrid families. Resulting larvae were stocked communally into ponds, seined as fingerlings, and separated into large-grade, small-grade, or ungraded groups for grow out. Juvenile HSB representing the three size-grades were stocked into replicated indoor recirculating systems and grown until they attained market size (680 g [1.5 lb]). An additional group of the large graded fish was grown in outdoor tanks at a separate facility to observe genotype × environment interactions. Fin clips were collected during final measurements for genotyping and parentage assignment. The results indicated that large, small, and ungraded hybrids required 12, 14, and 17 months, respectively, to attain market size indoors. Wild-strain-sired HSB displayed a lower range in final weights compared to domestic fish and grew larger in the ungraded treatment only. Florida-strain-sired fish were the largest and had the greatest condition factor (K), Virginia-strain-sired fish generally had the lowest K, and the other strains had intermediate K-values. No differences in final weight were found in the small or large graded fish from recirculating systems, but the domestic strain produced the largest HSB grown in outdoor tanks. These results demonstrated that HSB growth is influenced by sire strain, culture environment, and grading strategies.

SNP panel development for genetic management of wild and domesticated white bass (Morone chrysops)

et al. 2018

White bass (Morone chrysops), striped bass and their interspecific hybrid are important game fishes, whereas the hybrid striped bass is an important aquaculture species in the US. Numerous state, federal and private hatcheries, therefore, rear these species for stocking purposes as well as for food fish. Although striped bass populations (both wild and domesticated) have been extensively evaluated, relatively little effort has been directed toward the study and improvement of white bass. In this study, we developed SNP resources to examine the genetic relationships among a long-term domesticated white bass line and five potential founder stocks for selective breeding collected from drainages in Arkansas, Texas and Alabama. Using genotyping-by-sequencing, we generated 13 872 genome-wide SNP loci across the six populations. Stringent filtering of SNP-calling parameters identified 426 informative SNP loci. Population genetic and structure analyses using these loci revealed only moderate genetic differentiation between populations (global F st = 0.083) and indicated two major genetic clusters. A final 57-SNP assay was successfully designed and validated using the MassARRAY system. The developed SNP panel assigned 96 additional genotyped individuals to their population of origin with 100% accuracy. The SNP resources developed in this study should facilitate ongoing efforts in selective breeding and conservation of white bass.

To evaluate the pond culture potential of purebred Striped Bass Morone saxatilis, the thermal stress tolerance and associated feeding behavior of Atlantic coast (Delaware River; DE) and Gulf of Mexico (Florida; FL) strains (~1.0-1.6 kg) were evaluated. In the first experiment, critical thermal maxima (CTmax) temperatures were determined by gradually increasing the water temperature of individual fish that were housed in 311-L insulated containers (0.3°C/ min) and determining when the fish experienced loss of equilibrium (n = 6/strain). The results indicated that the fish from the FL strain had a higher CTmax value (36.7 ± 0.32°C) than did those from the DE strain (35.7 ± 0.57°C). In the second experiment, feeding behavior and feed consumption were evaluated during simulated summer temperature fluctuations by increasing the water temperature from 26°C to 34°C by 2°C every 2 d (n = 30 fish/strain). Feed consumption decreased inversely with temperature in both strains until a mortality event occurred at 34°C. The results suggest that there are physiological adaptations to elevated temperatures among Striped Bass strains and they may be suitable for pond culture if feeding is restricted at high temperatures (>30°C).
