“…In their natural environment, fishes of the family Esocidae are territorial and less aggressive toward others when widely dispersed in a water body. In a hatchery setting, it is often beneficial to take the opposite approach and stock them at a very high density to reduce the establishment of territories (Hecht and Pienaar 1993; Naumowicz et al 2017; Qiu et al 2022). Artificially increasing the turbidity of rearing tanks has several benefits for raising larval predators, including reduced cannibalism and side clinging behavior in Walleye (Clayton et al 2009).…”

ObjectiveJuvenile tiger muskellunge (Northern Pike Esox lucius × Muskellunge E. masquinongy) are cannibalistic, which can lead to a substantial reduction in yields within an intensive culture environment. Utah hatcheries have traditionally raised the female Northern Pike × male Muskellunge cross, and hatchery managers are reluctant to raise the female Muskellunge × male Northern Pike due to a perceived difference (increase) in cannibalism rates when rearing this cross.MethodsWe raised both crosses in replicated microcosms to evaluate the differential cannibalism between them. All rearing conditions were consistent among treatments and replicates. We evaluated weekly cannibalism using generalized linear regression models.ResultAfter 6 weeks, we found that the female Muskellunge × male Northern Pike cross offspring were significantly more cannibalistic than juveniles from the female Northern Pike × male Muskellunge cross, with total cannibalism across the 6‐week period estimated at 27% and 5.6%, respectively.ConclusionWe documented a previously unreported difference in tiger muskellunge cross cannibalism rates. Choosing the female Northern Pike × male Muskellunge cross could substantially increase survival of juvenile tiger muskellunge in aquaculture facilities.

“…Research on Striped Bass culture has been ongoing since the 1960s, and considerable information is available about their nutrition (Dougall et al 1996; Small and Soares 1998; Small and Soares 2000), feeding (Hung et al 1993; Kenter and Berlinsky 2022; Kenter et al 2022), health (Harms et al 1996), pond culture methodologies (Geiger and Parker 1985; Geiger and Turner 1990), larval rearing techniques (Geiger and Parker 1985; Martin‐Robichaud and Peterson 1998; Qiu et al 2022), stress mitigation (Harrell 1992; Kenter et al 2019), and reproduction (Hodson and Sullivan 1993; Weber et al 2000; Jenkins‐Keeran and Woods 2002; Clark et al 2005; Andersen et al 2021a, 2021b). Marine‐harvested Striped Bass, unlike hybrid Striped Bass (White Bass Morone chrysops × Striped Bass M. saxatilis ) that are grown in freshwater ponds extensively throughout the southern and Midwestern states, are preferred by consumers in many coastal states and lucrative ethnic markets, seafood restaurants, and sushi bars.…”

ObjectiveInvestigate Striped Bass Morone saxatilis growth in different photothermal environments and generate an interest in strain‐specific broodstock development for marine net‐pen culture.MethodsIn this effort, Striped Bass strains from Atlantic (Delaware, Virginia, and Maryland) and Gulf Coast (Florida and Texas) states were cultured in recirculating aquaculture systems, simulating a full‐production cycle to early market size in each respective region's photothermal environment. The Atlantic and Gulf strains were initially maintained in recirculating aquaculture systems “nurseries” until 400 and 160 days postspawn, respectively, when offshore conditions (temperature) were conducive for stocking juvenile fish. Individuals from all strains were implanted with PIT tags and stocked (“common garden design”) into a pair of identical recirculating systems (three 5000‐L tanks/system). One system received 48 Atlantic fish/tank (16 fish/strain; Delaware, Virginia, and Maryland), and the second system received 48 Gulf fish/tank (24 fish/strain; Florida and Texas). Salinity was maintained at 30‰, and photothermal regimes corresponded with ambient ocean conditions at selected locations off the mid‐Atlantic and Gulf coasts. Studies were conducted for up to 2 years, and production parameters (feed conversion, absolute growth rate, survival) were compared.ResultThe final weights of ungraded fish in both simulated locations averaged approximately 900 g by 600 days postspawn and early market size (~1.3 kg) by 800 days postspawn.ConclusionGrowth rates differed by strain in both nursery and grow‐out phases, but the results indicate high potential for production of Striped Bass in U.S. coastal waters.
