“…At current catfish feed prices (∼US$425.00 per ton) and an FCR of 6.2, the cost of feed to produce 1 kg of fish is approximately $2.90, nearly identical to the current pond-bank catfish price per kilogram. Development of new feeds for winter feeding or the incorporation of winter feeding into new, high-fish-density production systems (e.g., partitioned aquaculture systems; Brune et al 2004) may result in improved FCRs and better economics for winter feeding. High-density systems may improve winter FCRs because the fish are confined to a small area and may feed more efficiently.…”

The effects of winter feeding on growth, body composition, and processing yield were compared for co‐cultured blue catfish Ictalurus furcatus, channel catfish I. punctatus, and channel catfish×blue catfish hybrids. Fish (∼0.4–0.7 kg) from each genetic group were stocked communally at 5,625 fish/ha in ten 0.04‐ha ponds during mid‐November. Fish in five ponds were fed at 2% of initial body weight twice per week; fish in the other five ponds were not fed. The study was terminated after 14 weeks, and fish were weighed and processed. Analyzed traits were weight change (%), survival, and yields (%) of carcass, shank fillet, nugget, head, viscera, skin, intraperitoneal fat, liver, and ovary. Among fed fish, hybrids gained the most weight, channel catfish had intermediate weight gain, and blue catfish gained the least weight. Unfed blue catfish lost more weight than unfed channel catfish and hybrids. Survival was not different among genetic groups or between feeding regimes. Interactions among main effects for processing and body composition traits made generalizations difficult, but carcass yield was consistently higher for blue catfish and hybrids than for channel catfish, higher for females than for males, and higher for fed fish than for unfed fish. Shank fillet yield was higher for hybrids than for blue catfish and channel catfish, higher for females than for males, and higher for fed fish than for unfed fish. Nugget yield was higher for blue catfish than for channel catfish and hybrids and was higher for fed fish than for unfed fish. Blue catfish and hybrids had higher intraperitoneal fat yield and lower liver and ovary yield than channel catfish. Fed fish had higher intraperitoneal fat and liver yield than unfed fish. Winter feeding improved growth and fillet yield in all groups, but the benefits of winter feeding were lower for blue catfish than for channel catfish and hybrid catfish.

“…The toxicity of the forms of ammonia (NH 3 ) increases with water pH (the ammonia/ammonium ratio increases at pH 7 and above), which is one of the reasons for the importance of pH control in aquaculture. Aquaculture systems including autotroph biofloc technology (ABFT) [19], biofloc technology (BFT) [70], recirculating aquaculture systems (RAS) [71], and integrated multi-trophic aquaculture (IMTA) [72] systems such as aquaponic systems [73], constructed wetlands [74], integrated marine systems [75], high-rate algal ponds [76], periphyton systems [77], and partitioned aquaculture systems [78] aim mainly to remove nitrite-N (NO 2 -N) and ammonia (NH 3 ). Therefore, the four strains used in this study can be utilized in aquaculture, as they were shown to be excellent in their water-quality-improvement utilities.…”

Potential of Bacterial Strains Isolated from Coastal Water for Wastewater Treatment and as Aqua-Feed Additives

Bacteria have various and sustained effects on humans in various fields: molecular biology, biomedical science, environmental/food industry, etc. This study was conducted to evaluate the wastewater treatment capacity and feed-additive fish-growth effect of four strains of bacteria: Pseudoalteromonas mariniglutinosa, Psychrobacter celer, Bacillus albus, and Bacillus safensis. In a wastewater degradation experiment, (i) nitrate-N and nitrite-N were removed within 1 h in all of the 4 bacterial strains; (ii) the removal rates of TAN and TN were higher in all of the strains relative to the B. subtilis. In a feed-additive experiment (5% Kg−1), (i) the growth of fish was higher in all of the 4 bacterial strains with the B. subtilis relative to the commercial feed; (ii) there was no significant growth difference for B. albus and B. safensis relative to the B. subtilis, but growth was higher in P. mariniglutinosa and P. celer. The results indicated that the 4 bacterial strains can be effectively utilized for biological wastewater treatment processes and as aqua-feed.

“…Therefore, we developed a fish production system (the in-pond circulation system, IPCS) in which the fish could be held at high stocking densities. It was based on the experiences of the floating channel system from Parker (1988), the Dekel aquaculture system from Mires and Amit (1992) and the partitioned aquaculture systems described by Brune et al (2004). The IPCS has some advantages compared with pond breeding: accurate survey of stock every time, opportune detection and easy therapy of diseases, correct proportioning of feed at all times, complete protection from predators and theft, simple harvesting and last but not least increasing oxygen supply by the air transport by the mammoth pump.…”

Experiments for the production of hybrid striped bass in in-pond circulation systems

2007

Experiments for the production of hybrid striped bass (HSB) in in-pond circulation systems (IPCS) were carried out in 2003 and 2004. The circulation system consisted of two channels with a productive volume of 8.5 cubic meters each. The tanks were installed tightly in a pond, which served for the biological cleaning of the expiry water. In the first year HSB fingerlings with an average weight of 46.4 g were produced. The average yield in the basin was 51.2 kg/m 3 . The survival rate from stocked 0.44 g advanced fry was 97.8%. The food conversion was 1.16.In 2004 two-year-old HSB were reared in the same IPCS. The tanks were stocked at two different stocking densities, 122 and 244 fingerlings/m 3 with a mean weight of 36.5 g. In the tank with the larger stocking density, the yield was almost exactly twice as high as in the other tank (50.0 resp. 24.8 kg), which corresponded to a stocking density of 59.1 or 29.3 kg/m 3 at the end of the rearing season. The stocking density had no influence on the increase of the individual body weight. Obviously HSB can therefore still be reared at higher stocking densities.
