“…African catfish can tolerate a wide range of freshwater habitats and can still survive for weeks when they burrow into the sediment and mud of ponds. Consequently, C. gariepinus (African catfish) is well-studied in terms of nutrition ( 16 , 17 ), feeding behavior ( 18 , 19 ), management and reproduction techniques ( 20 ) and welfare ( 21 – 23 ), among others. In addition, Hossain and Beveridge ( 24 ) studied the effect of light and shelter on the growth and survival of C. gariepinus , Schram et al ( 25 ) enriched the diet of C. gariepinus with functional selenium, Arechavala-Lopez et al ( 26 ) reviewed the effect of environmental enrichment on cultured fish species and ( 22 ) assessed the effect of chronic stressor on welfare indicators of C. gariepinus .…”

Environmental enrichment (EE) improves the growth rate and welfare of some cultured fishes. However, most cultured fish species are raised in non-enriched housing conditions. Clarias gariepinus is an important commercial fish species, but little is known about the effect of EE on their welfare. This study examined the effect of different EE on the survival rate (SR), growth [mean weight gain (MWG), specific growth rate (SGR) and feed conversion ratio (FCR)], behavioral (feed response, aggressive acts and shoaling time) and physiological responses (blood glucose) of C. gariepinus. One hundred and twenty juveniles of C. gariepinus (31.65 ± 0.69 g) were randomly allocated at 10 fish/tank and subjected to either Plant Enriched (PE), Substratum Enriched (SE), Plant and Substratum Enriched (PSE) and Non-Enriched (NE) tanks in triplicates for 56-days. Behavioral acts were observed for 10 min twice daily, and glucose level in blood samples was evaluated. Data were checked for normality using the Shapiro-Wilk test before being analyzed with the Kruskal-Wallis test. SR and MWG were significantly higher in Clarias gariepinus exposed to SE, with no significant differences among PE, PSE and NE treatments. There was no significant difference between the SGR of PSE and NE. FCR was similar between treatments. The highest condition factor (k) was recorded in SE tanks. Duration of feed response was shorter in SE, but there was no significant difference between the feed response of C. gariepinus exposed to PE and PSE. C. gariepinus exposed to PE, SE and PSE displayed a similar frequency of aggressive acts. African catfish reared in NE (barren) tanks had the least duration of shoaling period. The experiment consistently found the highest and least glucose values in PSE and SE. In conclusion, environmentally enriched housing tanks with SE resulted in the best MWG with a reduced level of aggression in C. gariepinus under laboratory conditions. Thus, EE might be applicable to boost fish productivity on a commercial scale.

“…After the yolk sac has been absorbed, there is widespread mortality in the early stages of development 12 . The study of the breeding performance of C. batrachus by various hormones with different doses is poor 13,14 . Information on the effects of temperatures and the latency period on the breeding efficiency of C. batrachus is very rare.…”

Background and Objective: Clarias batrachus is an important freshwater fish of Bangladesh and is locally known as Magur. It has great commercial value due to its taste and economic aspect. This study was undertaken to establish the natural spawning of Clarias batrachus in captive conditions. Materials and Methods: The experiment was conducted at the hatchery of Bangladesh Fisheries Research Institute, Freshwater Sub-Station, Saidpur to determine the reproductive response of Clarias batrachus using different types of hormones. The average length and weight of brood used for the breeding trial was (26±2.0 cm an average weight of 160±4 g) and female (average length of 24±3.0 cm and an average weight of 210±6.0 g) Clarias batrachus. To detect ovulation, fertilization, spawning, hatching and survival different doses of the hormone were used due to optimizing the hormone doses. Results: After 24-28 hrs of injection, natural spawning was found successful in all cases except in T 1 . The case of PG (20 mg kgG 1 for females and 10 mg kgG 1 for males with ovuhom 1 mL kgG 1 for females and 0.5 mL kgG 1 for males) shows better results in terms of ovulation, fertilization and hatching and survival in T 3 rathe than T 2 . In the higher dose, almost 100% of fishes spawned naturally and fertilization and hatching rates were also higher. Hatching of fertilized eggs occurred between 30-35 hrs of incubation at 27 to 28EC and the larvae started to feed within 72 hrs after hatching. Conclusion: This is considered a landmark in the strategy of saving this male from sacrificing, by establishing this technique for mass production of fry Clarias batrachus.
