“…Taking in account the cost effectiveness of particular diet, food content may have striking effects on feed behavior and fish nutrition. The trial to improve the feeding strategies is to improve the fisheries welfare (Silva et al, 2016). The current aquaculture practice was administered to search for feed ingredients that can be used to formulate significant fish feed and to enhance fish production (see Fig.…”

In aquaculture industry, the aim of feed formulation is to provide the fish with feasible diet to enhance their body. Carbohydrates supplemented with chromium compounds (organic and in-organic) are major energy currencies for biological machinery of fish. Here, this article presents a description that emphasizes the effect of chromium picolinate (organic) and chromium chloride hexahydrate (in-organic) on growth execution and genotoxicity of Labeorohita. Seven groups (each with a replica) with 30 Labeorohita fingerlings were formed: a control group, three groups were supplemented with chromium chloride Hexahydrate (0.3, 0.5 and 0.6 mg kg−1) and three groups were supplemented with Cr-Pic, 0.3, 0.5 and 0.6 mg kg−1) respectively. The experimental group T4 fortified with (Cr-Pic) along with carbohydrates by dose of 0.3 mg/kg demonstrated significant results (P < 0.05). Superior growth for Labeo rohita was observed as compared to control and other experimental groups. Minimum growth trend was observed in group T5 (CP-0.5 mg/kg), T6 (CP-0.6 mg/kg) and T7 (control) respectively. Comet assay results indicated the dose and Cr related (organic or in-organic) genetic damage in fish erythrocytes. Hence, maximum comet parameters (Tail length, Tail DNA and Olive Tail Moment) were observed in (in-organic Cr) by 0.3 mg/kg concentration. This study suggested the toxicity corresponding to in-organic Cr but organic Cr could be used as growth promoter if so. Overall results demonstrated supplementation of organic chromium compounds by 0.3 mg/kg should be reconsidered for growth. This drive of research address the fish farmers to utilize the feed supplemented with organic Cr compounds which is most appropriate to provide sustainable yield as part of increment in growth performance and beneficial health effects for consumers on indices to reduce the toxicity risks.

“…A paradigm that is often used to study learning ability is associative learning using food rewards. In fish, one approach to study feeding behavior and learning is the use of self-feeders ( da Silva et al., 2016 ). Fish are able to activate self-feeders through a “trigger” sensor placed in the water, a learning process based on operant conditioning associated with a food reward ( Benhaïm et al., 2017 ; da Silva et al., 2016 ).…”

Self-feeders have successfully been used with several fish species mainly to study daily rhythms of feeding behavior and nutrient selection ( da Silva et al., 2016 ; del Pozo et al., 2011 ). When fish are allowed to self-feed, they display a daily rhythm of behavior entrained by the light/dark (LD) cycle, with a preference for activity during either the light or the dark phase.…”

A feeding trial was carried out to assess the effect of dietary chromium supplementation on apparent nutrient digestibility coefficient (%) of gelatinized and non-gelatinized corn in Cirrhinus mrigala fingerlings for 90 days. Using various levels of chromium chloride hexahydrate six test diets designated as T1 (G/0.0 Cr2Cl3.6H2O mg Kg-1), T2 (NG/0.0 Cr2Cl3.6H2O mg Kg-1), T3 (G/0.2 Cr2Cl3.6H2O mg Kg-1), T4 (NG/0.2 Cr2Cl3.6H2O mg Kg-1), T5 (G/0.4 Cr2Cl3.6H2O mg Kg-1) and T6 (NG/0.4 Cr2Cl3.6H2O mg Kg-1) were prepared. Results showed highest apparent digestibility coefficient (ADC) of nutrients dry matter, crude lipid and gross energy in test diet T5 that was gelatinized and supplemented with chromium 0.4 mg/Kg while, for crude protein higher value of nutrient digestibility was recorded in T3 test diet (G/0.2 Cr2Cl3.6H2O mg/Kg). It was concluded that chromium supplementation with gelatinized corn in fish (Cirrhinus mrigala) diet can improve the nutrients digestibility more efficiently.
