“…Generally, some studies report a favorable effect of higher stocking density on the survival of cultured C. gariepinus [126] due to the ability of the fish to breathe atmospheric oxygen when the arborescent organ becomes fully developed [127]. Due to this, a number of studies recommend stocking C. gariepinus at high densities of 9-15 fry per m 2 [126,128]. Obviously, more studies are required to clearly understand the effect of stocking density on the survival of farmed C. gariepinus fry, fingerlings, or grow-out fish.…”

The culture of African catfish, Clarias gariepinus, is constrained by the high mortality of fry, occasioning a shortage of high-quality seeds for stocking by farmers. Asia, a continent with many success stories for aquaculture, leads in farmed production of some catfishes, a diverse group of 37 different families. Globally, the culture of catfishes ranks fifth in global farmed finfish production. Globally, Vietnam leads in the production and export of farmed striped catfish, Pangasianodon hypophthalmus, with 1,400,000 tonnes produced annually from about 7,000 hectares. Similarly, China farmed the non-native Channel catfish, Ictalurus punctatus, into the major crop, with a current annual production of 250,000 tonnes. On the contrary, C. gariepinus, the main farmed catfish species in Africa, records low annual yields, with 240,000 tonnes for the whole continent. This paper explores the factors behind the high production of P. hypophthalmus and I. punctatus in Vietnam and China, respectively, and draws lessons for C. gariepinus farmers in Africa. Specifically, the use of differentiated hatchery and nursery husbandry practices was critical in boosting seed production, quantity, availability, and distribution for expanding the culture of P. hypophthalmus in Vietnam. Improvement of fish species through well-designed genetic improvement programs helped China substantially increase production of I. punctatus. For both species, intensive fish production, as well as the adoption and implementation of suitable policies, increased seed production from hatcheries in both countries. These are discussed as some of the factors that spurred catfish production in the two Asian countries. We argue that if these are adopted by farmers in Africa, they could help improve the production of farmed C. gariepinus on the continent for food and nutrition security as well as generation of livelihood for local communities.

“…Both monoculture and polyculture system are suitable for this species which also exhibit satisfactory production performance in drought prone area. The effect of stocking density on growth and survival of some fishes all over the world has been addressed (Sahoo et al 2004, Pangni et al 2008, Nwipie et al 2015, Swamy et al 2018, Goswami and Ghosh 2022. Several studies regarding the same issue have also been described in our country such as Bostami et al (2020) on Cyprinus carpio var.…”

An experiment was conducted to assess the effect of stocking density on growth, survival and production performance of Clarias batrachus (Magur) fry using nursery hapa in experimental pond of Dept. of Fisheries, University of Rajshahi. The research was carried out for a period of three months from May to July, 2021 consisting of four treatments each with two replications. A total of eight hapa were prepared using net each having an area of 1.2 × 0.9 × 0.9 m3. Stocking density was maintained at the rate of 300, 350, 400 and 450 fry ∕ m3 in T1, T2, T3 and T4 respectively where the mean initial weight of hatchling was 0.04±0.01 g. Different physico-chemical parameter of water were monitored fortnightly where the mean value of water temperature, water transparency, dissolved oxygen, carbon dioxide, PH and NH3-N was observed 28.25±1.18°C, 26.12±0.18 cm, 8.44±0.45 mg/l, 1.78±0.03 mg/l, 6.88±0.04 and 0.007± 0.00 mg/l respectively. Except NH3-N no significant difference (p˃0.05) was found among the treatments and all the parameter were in suitable range for fry rearing. Highest mean final weight, weight gain, SGR (%/day), survival rate, along with lower FCR was found in T1 which was 8.00±0.13 g, 7.96±0.07 g, 5.65±0.00 (%/day) and 91±0.70 (%) respectively followed by T2, T3 and T4 where significant variation (p˂0.05) was found among them. Maximum net yield (kg/m3/90 days) was 2.51±0.07 which was obtained from T3 followed by 2.48±0.02, 2.37±0.02 and 2.20±0.05 in T4, T2 and T1. On the other hand, benefit cost ratio (BCR) was found significantly higher (p˂0.05) in T1 (0.73±0.01) than T2 (0.66 ±0.01), T3 (0.56±0.00) and T4 (0.43±0.02). The overall result indicated that a stocking density of 300 fry/m3 (T1) could be more profitable for Clarias batrachus fry rearing in nursery hapa. J. Bio-Sci. 31(1): 17-27, 2023

The main aim of this study was to assess the effect of water depth on the growth performance (length and weight) of table size Indian major carp (Gibelion catla, Labeo rohita, and Cirrhinus mrigala) fi shes. Fishes were recorded under different depth (1.20 m, 1.80 m and 2.80 m) for about eight months from February 2016 to September 2016. Water depth was considered as treatment 1 (T 1 ) for 1.20 m, treatment 2 (T 2 ) for 1.80 m and treatment 3 (T 3 ) for 2.80 m, respectively. Randomized Complete Block Design (RCBD) with two replications of each treatment was differentiated at signifi cant level 0.05. Various water quality parameters such as water temperature, dissolve oxygen, transparency, and pH were also recorded. The survival rate was found maximum (99.23±0.4%) for Labeo rohita fi sh at 2.80 m water depth and lowest (95±2.1%) survival rate was observed for Gibelion catla fi sh at 1.20 m water depth. Results of this study showed that Gibelion catla, Labeo rohita and Cirrhinus mrigala fi sh cultivated at four feet depth of water produces lowest average weight of 1398 g, 1048 g and 1050 g, respectively with an average length of 47 cm, 49.2 cm and 46.4 cm, respectively. The maximum average weight of fi sh 3667 g, 2700 g and 2800 g were obtained at 2.80 m depth of water with the maximum average length of 63.2 cm, 60.0 cm and 58.6 cm for Gibelion catla, Labeo rohita and Cirrhinus mrigala fi sh, respectively. From this study, it can be observed that the fi shes cultivated at low depth of water yielded lowest, and shorter in length in contrast to the carps cultivated at higher depth of pond water. However, growth of Gibelion catla was notably high among other carps.
