“…However, in general, several studies have reported that exogenous administration of estradiol-17 causes a significant decrease in testosterone concentration accompanied by an increase in estradiol concentration in fish (Yuan et al, 2012;Khara et al, 2013). Another impact of increased testosterone was an increase in aggressiveness in fish which was closely related to the incidence of cannibalism in fish (Maruska and Fernald, 2010;Black et al, 2011;Kania et al, 2012;Chang et al, 2012;Peterson et al, 2013;Alcazar et al, 2016;Rahmadiah et al, 2019). Alcazar et al (2016) stated that there was a relationship between steroid hormones and aggression in fish.…”

Highlight Research The dose, duration of immersion, and time interval of immersion of the estradiol-17β affect the rate of cannibalism and increase the seed survival of Asian redtail catfish in low treatment in this research. Over optimum treatment increased the incidence of cannibalism at Asian redtail catfish and decrease growth performance. Treatment of estradiol-17β, give the ability of Asian redtail catfish to live on high density The treatment of estradiol-17β, has an effect on concentration plasma of body testosterone and cortisol Abstract The cannibalistic behavior of Asian redtail catfish greatly hampers the supply of these fish seeds, invoking the need to be controlled. Estradiol is one of the hormones that has been known to reduce cannibalistic behavior on fish. This study aimed to evaluate the effect of estradiol-17β immersion on the incidence of cannibalism in the rearing of post larvae of Asian redtail catfish. Post larvae was treated with a combination of doses of estradiol hormone 0, 1, and 2 ppm and immersion time of two and four hours with immersion intervals of three and six days with a completely randomized design. Each treatment had a fish density of 10 fish L-1, with mean size individual length of 6.73 ± 0.73 mm (three days of age after hatched), with four replications. Fish were fed with tubifex up until satiation point and reared for 30 days. The results showed that the administration of the estradiol-17β through immersion with a dose of 1 ppm for two hours and interval of six days was able to reduce the level of cannibalism and increase the survivability. A further increase in dose, immersion time, and interval had the opposite effect. Estradiol-17β immersion with certain dose, duration, and interval affected the rate of cannibalism, growth rate, and survival. Estradiol-17β immersion at a dose of 1 ppm for two hours and six days interval was the best to reduce the level of cannibalism and normal mortality in post larvae of Asian redtail catfish.

“…Previous studies have been reported that overcrowding in aquaculture system could result in lower survival and growth and increase stress (Manley et al, 2014;Qun et al, 2016). In African catfish culture, mortality might also be caused by cannibalistic behaviour in particular when the fish was varied in size (Biu et al, 2015;Rahmadiah et al, 2019). The fish growth in biofloc systems generally showed higher performance than that of the control, regardless the fish density.…”

This study aimed to evaluate the production performance and nitrogen and phosphorus mass balance of biofloc-based intensive African catfish Clarias gariepinus culture at different densities. African catfish with an average body weight of 2.64 ± 0.06 g was randomly distributed into 12 units of round tank with a working volume of 2 m3 of water and maintained for 8 weeks. A completely randomized experimental design with four treatments (in triplicates), i.e. a control treatment at a fish density of 500 fish m-3 with regular water exchange and without organic carbon source addition, and biofloc treatments (BFT) at three different densities, i.e. 500 fish m-3 (BFT500), 750 fish m-3 (BFT750), and 1000 fish m-3 (BFT1000). Biofloc systems were performed with a regular addition of tapioca flour (40% C). The production performance between biofloc system and the control was not significantly different, however water and nitrogen utilizations were significantly more efficient in biofloc system than those of the control. The highest fish specific growth rate was observed in BFT1000 and BFT500 (6.01% day-1 and 5.96% day-1, respectively) (P<0.05). Fish density significantly affected the fish growth performance and productivity in biofloc systems, but not nitrogen and phosphorus utilizations. In conclusion, higher fish density significantly increased the production and water utilization efficiency in biofloc systems, but has no effect on nitrogen and phosphorus utilization efficiency. Furthermore, increasing the fish density could significantly reduce the fish survival and require more efforts to control biofloc biomass in the culture system.

“…The high androgen hormone level during the parent's gonad maturation will be inherited by the catfish larvae which then becomes a trigger for aggressive behaviour in larvae (Zairin et al, 1992). Rahmadiah et al (2019) worked with three methyl testosterone (MT) concentrations and two stocking densities. The results showed that the larvae from female broodstocks injected with MT 2 μg/g body weight and stocking densities 6000/m 2 increased the aggressiveness of swim, but decreased cannibalism.…”

Cultivation of African catfish Clarias gariepinus is an industry-based leading commodity and is growing rapidly in Indonesia. Increasing catfish production requires support from a continuous supply of high-quality fingerlings. The application of appropriate technology would be very beneficial in increasing productivity in catfish fingerling production, especially in overcoming the issue of cannibalism which contributes to more than 50% of juvenile African catfish mortality (Hecht & Appelbaum, 1988; Appelbaum & Van Damme, 1988).Cannibalism in catfish begins at three and a half days after they begin eating (at an average total length of 8 mm) and increases significantly when they approach an average length of 80 mm or 47 days after they begin eating (Adamek et al., 2011;Mukai et al., 2013).There are two types of cannibalism and both are the main function of the correlation between predator mouth width and prey head width. Type-I cannibalism occurs in juveniles measuring 8-45 mm
