“…Thus, goldfish had access to zooplankton as an additional food source, although the level was approximately one-third the amount found in the water of the supply pond (583 organisms/ L); this difference was possibly due to destruction of organisms in the water pump. The level of zooplankton available to goldfish in the present study was considerably lower than that reported for fertilized ponds used for aquaculture production of koi (domesticated common carp Cyprinus carpio) and goldfish (Jha et al 2006a(Jha et al , 2006b.…”

Prebiotics recently have been shown to increase immune responses and disease resistance in certain fish species; therefore, the current study was conducted to evaluate the commercially available dairy-yeast prebiotic, GroBiotic-A, for use with juvenile goldfish Carassius auratus. The study consisted of two 10-week feeding trials in which juvenile goldfish were fed practical diets that were either unsupplemented or supplemented with the dairy-yeast prebiotic at 2% by dry weight. Juvenile fish were sorted by size and stocked into 12 units within each of two culture systems: one indoor system supplied with recirculated well water and one system located outdoors with a continuous flow of pond water to provide a source of phytoplankton and zooplankton. Both diets were fed to fish in six units within each system at the same fixed percentage of body weight twice daily. Culture system (i.e., presence or absence of phytoplankton and zooplankton) was the primary factor influencing (P < 0.0001) percent weight gain, feed efficiency, and survival of goldfish during the feeding trials. No dietary effect was detected, although there was a significant (P < 0.05) interaction between culture system and diet, with supplementation of the dairy-yeast prebiotic tending to improve weight gain and feed efficiency of fish in the presence of phytoplankton/zooplankton. During a controlled disease challenge with an intraperitoneally administered dose of Aeromonas hydrophila that was equivalent to a predetermined LD50 (dose lethal to 50% of test fish), average survival values ranged between 67% and 83% for fish that previously had access to phytoplankton/zooplankton compared with 17-33% for fish that had no access to phytoplankton/zooplankton. The dairy-yeast prebiotic, however, did not enhance resistance of goldfish to the bacterial pathogen and did not greatly alter microbiota of the anterior or posterior gastrointestinal tract based on denaturing gradient gel electrophoresis analysis. In conclusion, the dairy-yeast prebiotic did not improve feed efficiency in goldfish or resistance to a bacterial pathogen as previously observed in golden shiners Notemigonus crysoleucas and hybrid bass (white bass Morone chrysops X striped bass M. saxatilis).

“…Not surprisingly, the effectiveness of duoculture is dependent on the species concerned. For example, Atlantic salmon feed less, grow less well and have more fin damage when reared in duoculture with brown trout than when reared in monoculture , as do goldfish (Carassius auratus) reared in duoculture with koi carp (Cyprinus carpio; Jha et al 2006), because they are attacked by the trout and koi respectively.…”

Aggression (behaviour that actually or potentially causes harm to another animal) is widespread among fishes, often taking the form of territoriality or dominance. The mechanisms that control aggression in fish are described, including the effects of stimuli from opponents, the importance of the context in which an aggressive encounter occurs and the effects of nutritional condition, endocrine status and brain biochemistry. The way aggression changes during development is then considered, evidence given for inherited differences in aggressiveness and an account presented of the environmental factors that influence the way aggression develops. The benefits that fish gain from winning fights, the costs that they incur from fighting and how they balance costs against benefits to promote their individual fitness are described. Data are then given on the incidence of aggression among cultured fish, on some resulting problems for production, welfare and environmental protection and on the effects of domestication and captive rearing of aggressiveness. Possible solutions to such problems are discussed, based on selecting appropriate fish for culture and the design of husbandry systems that minimise aggression. Finally, some systems for mitigating the effects of domestication and captive rearing on the aggressive behaviour of cultured fish are described.

“…Cyprinid larvae are known to prefer natural food items such as free-living protozoa and rotifers, and larger planktonic organisms like cladocerans and copepods at fry and fingerling stage (Jhingran and Pullin, 1985). Studies on feeding behaviour and food selection of koi carp and goldfish indicated a strong preference for cladocerans and negative selection of copepods and phytoplankton (Jha and Barat, 2005b;Jha et al, 2006b). Significantly higher growth and survival rates were observed in koi carp fry fed with exogenous plankton, compared with pelleted diet (Jha and Barat, 2005b;Jha et al, 2006a;Jha et al, 2007).…”

“…The koi carp, Cyprinus carpio are cultured at a density of 0.25 fish/l in Hawaii (reported in Asano et al, 2003) and 0.3 fish/l in India in outdoor tanks and ponds fed with either pelleted diet or live plankton (Jha and Barat, 2005a;Jha and Barat, 2005b;Jha et al, 2006a;Jha et al, 2007). The goldfish, Carassius auratus has also been cultured at a density of 0.3 fish/l in outdoor ponds and fed with live plankton (Jha et al, 2006b).…”

Para explorar la utilidad de diferentes regímenes de manejo para intensificar la cría del ciprínido Epalzeorhynchus frenatus, larvas del pez (0,18 ± 0,014 g) fueron cultivadas durante tres meses (18 febrero-18 mayo 2007) en tanques de hormigón, de acuerdo con seis tratamientos: tres regímenes con alimento vivo en los que los peces se mantuvieron a una densidad de 0,3 (LF1); 0,5 (LF2); y 1,0 pez/l (LF3); y otros tres regímenes con alimentación tradicional (granulada) en los que los peces se mantuvieron a una densidad de 0,3 (TD1); 0,5 (TD2); 1,0 pez/l (TD3). Se introdujo plancton exógeno en los tanques con alimento vivo. Se hicieron tres repeticiones por tratamiento en las que los peces fueron alimentados cada día ligeramente en exceso del nivel de saciedad, para eliminar la posibilidad de que el suministro de alimento fuera un factor limitante del crecimiento. Los valores del oxígeno disuelto fueron más altos en el tratamiento LF1, seguido por LF2, TD1, LF3, TD2 y TD3 (p
