“…A number of studies have focused on feeds, feeding strategies, and stocking density for the early larval stages of hybrid striped bass production. Sunshine bass fry have been cultured successfully in tanks when fed with freshwater rotifers Brachionus calyciflores only (Ludwig 1994b), with a combination of freshwater rotifers and salmon starter feed (Ludwig 1994a), or a sequence of enriched rotifers, brine shrimp nauplii, and highprotein dry feed (Ludwig 2006). Ludwig and Lochmann (2000) used a drum filter to collect zooplankton with a 60-µm-mesh filter.…”

Year-round production of hybrid striped bass (female white bass Morone chrysops × male striped bass M. saxatilis) fingerlings would allow food fish growers to sell their product throughout the year, which would improve the consistency of market supply and cash flow for the farm. However, pond production of fingerlings is seasonal and precludes year-round supply. Tank culture methods have been developed to produce hybrid striped bass fingerlings indoors throughout the year, but the associated costs have not been estimated or compared with pond production costs. Economic engineering techniques were used to estimate production costs for phase I hybrid striped bass fingerlings in ponds (0.4, 1.2, or 2.4 ha) and tanks (945, 2,457, or 5,670 L) for production scales of 50,000, 100,000, 250,000, 500,000, 1,000,000, or 2,000,000 fingerlings per year. The results demonstrated that there are economies of scale in terms of the volume of production and the size of the production unit. Overall, pond production per 1,000 fingerlings was substantially less expensive than tank production, even accounting for the increased number of annual production cycles in tanks. Production costs were sensitive to survival rates and can be reduced by 7-14% and 5-11% for each 5% improvement in survival in ponds and tanks, respectively. Substituting microcyst brine shrimp for rotifers Artemia spp. in the diet may have the potential to reduce the tank costs of producing hybrid striped bass depending on fingerling survival beyond 14 d posthatch. Additional research is needed to improve overall fingerling survival both during the early fry rearing stage and after training to dry feed.

Determining optimum parameters for tank culture of sunshine bass (white bass Morone chrysops × striped bass M. saxatilis) fingerlings will facilitate a year‐round supply of seed for the production cycle of this increasingly popular food fish. This experiment determined the relationship between the stocking density of sunshine bass larvae in tanks and their survival rate and size at the time they were trained to accept commercial feeds. Four‐day posthatch (dph) larvae were stocked at 10 densities from 30 to 120 larvae/L in 10‐larvae/L increments. Larvae were initially fed rotifers Brachionus plicatilis cultured with Nannochloropsis spp. algae paste and commercial rotifer feed at 60 rotifers·mL−1·d−1 until 10 dph. Conversion to brine shrimp Artemia spp. began at 7 dph. The daily ration of brine shrimp started at 4/mL and increased by 4/mL every 4 d up to 20/mL. Training to dry starter feed began at 20 dph when 6 g/d of a commercial larval starter meal was offered; 2 d later, salmon starter meal was offered at 8 g/d in 10 equal portions. Photographs of live samples of larvae taken at 4 dph and harvest were used to determine the lengths of the fish. Regression analysis revealed that there was no significant relationship between survival and stocking density. The length and weight of the fish had a linear, negative relationship with stocking density, whereas total tank yield had a curvilinear relationship with stocking density. Under the conditions of this experiment, a stocking density of 87 larvae/L provided the maximum yield.

“…Such a strategy has been used successfully for other species. In the United States and Israel, RAS technology is used for year-round production of sunshine bass (Morone saxatilis) and tilapia (Oreochromis niloticus) in an e¡ort to overcome slow growth and mortalities in ponds during winter (Halachmi et al 2004;Ludwig 2004). In Taiwan, a combination of RAS and extensive systems is used in the production of the Figure 3 Growth of silver perch ¢ngerlings stocked at densities of 500, 1000 or 1500 ¢sh m À 3 in 1m 3 tanks in a recirculating aquaculture system and cultured for 99 days.…”

Slow growth and losses to bird predation and infectious diseases in winter can compromise the profitability of silver perch farming. To evaluate over‐wintering silver perch (Bidyanus bidyanus) in a recirculating aquaculture system (RAS), fingerlings (38 g) were stocked in either cages in a pond at ambient temperatures (10–21 °C) or tanks in the RAS at elevated temperatures (19–25 °C) and cultured for 125 days. Mean survival (96%), final weight (146 g), specific growth rate (1.07% day−1) and production rate (28.1 kg m−3) of fish in the RAS were significantly higher than for fish over‐wintered in cages (77%, 73 g, 0.53% day−1, 11.1 kg m−3). Fish from both treatments were then reared in cages for a further 129 days. Final mean weight of fish originally over‐wintered in the RAS was 426 g, while fish over‐wintered in cages were only 273 g. To determine optimal stocking densities, fingerlings (11.8 g) were stocked at 500, 1000 or 1500 fish m−3 in tanks in the RAS and cultured for 124 days. Survival was not affected, but growth was significantly slower and feed conversion ratio higher at 1500 fish m−3 compared with 500 or 1000 fish m−3. Results demonstrate that over‐wintering silver perch in an RAS can produce large fingerlings for grow‐out in early spring. This strategy could eliminate bird predation, reduce losses to diseases and shorten the overall culture period.
