“…For example, the survival and growth rate of the catfish Rita rita , at different densities of 10, 20 and 30 fish per cistern, resulted in the highest survival and SGR in 20 fish per cistern. Further, no competition for feed and space observed at low density culture of this fish 24 . In contrast, a prior study revealed that survival rate in aquatic animals was negatively correlated with stocking which could be due to high competition and space for the fish 2 .…”

Background: Stocking density is key to successful Majalaya common carp ( Cyprinus carpio Linnaeus 1758) culture which is a valuable fish culture in Indonesia. The aim of the present study was to evaluate the growth statues, feed utilization, and survival rate of Majalaya common carp (reared with different stocking density. Methods: In total, 1400 fish were randomly distributed into four replicates of four different groups of stocking density: 50, 75, 100, and 125 fish m −3. All fish were fed using a satiation method, three times per day with commercial diet for 12 weeks. At the end of the trial week, growth, feed utilization, and survival were determined. Water quality measures, such as dissolved oxygen (mg L -1), temperature (°C), pH, NH 3 (mg L -1), and NO 2 (mg L -1) were also measured once a week during the trial. Results: Similar weight gain and SGR were found in Majalaya common carp reared at stocking densities of 50 to 100 fish m 3. However, 125 fish m -3 density may reduce weight gain and SGR. The average weekly and daily weight gain of Majalaya common carp significantly increased when reared from 50 to 100 fish m -3 and remained constant at 125 fish m -3 density. Meanwhile, feed conversion ratio and survival of Majalaya common carp were not affected by any stocking density. Conclusions: A stocking density of 100 fish m -3 exhibited significantly higher growth of Majalaya common carp in hapa net ponds among the treatment. Temperature ranges of 29.20-33.38°C, pH 7.47-8.22, DO 4.76-7.55 (mg L -1), NH 3 0-0.5 mg L -1, and NO 2 0-1 mg L -1 were found to provide optimum condition to the fish.

“…However, catfish almost occupy every habitat type in lakes, ponds, rivers, and streams, as well as still and moving waterways (Thebo et al, 2019). Catfishes are one of the most important fisheries and aquaculture resources, and they have adapted in a variety of morphological, physiological, and ecological ways, particularly to shallow depths, low oxygen levels, and high turbidity ( Jalbani et al, 2018). For this reason, the current study was carried out to provide fundamental information on the interrelation of several body measures of Claris gariepinus grown in cemented ponds, as there is a dearth of literature on any aspect of the biology of this commercially significant fish from Pakistan.…”

C larias gariepinus is regarded as a fast-growing aquaculture species for large-scale and small-scale farming in African nations because it provides a partial solution to the rising protein needed (Ajani and Awogbade, 2012). According to them, the practices of its culture in recent years closely resemble those Abstract | The inter-relationship of various body measurements with regard to length in Clarias gariepinus, reared in cemented ponds was initiated from March-September 2021 by using 200 individuals (110 males and 90 females).These specimens of experimental fish ranged from 14.4 to 37.0 cm in length and from 44.7 to 985 g in weight and were obtained from the stock marinated in the cemented ponds of the University of Sindh, Jamshoro. At 5cm intervals, samples of fish were separated into groups. Fish body dimensions, including fish head length, fin measurements and the diameter of fish eyes and mouth gape were examined. No significant difference between male and female was noted; though, there was a small variation in the percentages of lengths such as standard and anal fin, which were greater in females (85.0 and 15.3 percent, respectively) than in males (83.2 and 10.6 percent, respectively). The length of the head, the width, the pectoral fin, the pelvic fin, and the dorsal fin were all bigger in males ( 90
