Several research reports on initial fry size in fish rearing as stated by [6], used catfish fry sizes 9.5 ± 1.7 cm long and 7 ± 2 grams in weight. Sangkuriang catfish frys were 2 -3 cm (2.9 g) /head) and 5 -8 cm (6.2 g/head) [7] Soedibya et al, [8], using fry size test fish have an average weight of 1.85 ±0.09 g reared in terpoline ponds with a diameter of 1.72 m and a height of 1.05 m with a water volume of ±2,000 L in four units with different densities, namely 1,000 individuals/m³, 1,500 individuals/m 3 , 2,000 individuals/m³, 2,500 fish/m³ With a weight of 20-30 g/head, tilapia fry are reared in circular tanks with a density of 55-80 fish/m³ or equal to 0.7-3 kg/m³. ...
The purpose of this research was to analyze how the performance of growth and survival of climbing perch - papuyu fish (Anabas testudineus Bloch) aquaculture with the biofloc system whether there were differences in the sex ratio of the stocked climbing perch had an effect and to find the right sex ratio. The experimental design used in this research was a completely randomized design (CRD) with 5 treatments and 5 replications, resulting in 25 experimental units. Treatment B100J0 = 100% female climbing perch and 0% male, treatment B75J25 = 75% female and 25% male climbing perch, treatment B50J50 = 50% female and 50% male climbing perch, treatment B25J75 = 25% female climbing perch and 75% male % and Treatment B0J100 = 0% female climbing perch and 100% male fish. The research was conducted for 90 days with daily growth parameters (SGR), weight and length growth, survival rate, food conversion, flock content, and main water quality parameters (water temperature, pH, dissolved oxygen and dissolved ammonia). From the results of the research it can be concluded that the difference in sex ratio has a significant effect on the weight growth of climbing perch with a 100% ratio of females for enlargement resulting in the best daily growth rate. The B100J0 treatment was better, that in subset 1 the treatments B0J100, B75J27 and B50J50 were the same. In subset 2, treatments B50J50 and B75J25 were the same, while in subset 3, treatments B75J25 and B0J100 had the same growth. However, based on the median value, treatment B100J0 was better than treatments B75J25 and B50J50 and other treatments. The difference in relative weight (%) between treatments indicates that treatment B100J0 23.72% from treatment B75J25, 54.57% from treatment B50J50, 86.39% from treatment B25J75 and 172.87% from the B0J100 treatment. thus treatment B100J0 = 100% female and 0% male is the best treatment. This phenomenon indicates the sex of the papuyu fish with a ratio of 100% female to rearing produces the best daily growth rate. The results of the research using the sex composition obtained an additional length (cm) for 90 days for each treatment B100J0 = 1.92 cm, B75J25 = 1.19 cm, B500J50 = 1.78 cm, B25J75 = 1.31, B0J100 = 1.61 cm, indicating length The standard depends on the other types of climbing perch, the variety of fish species tested and the length of time they are kept. Treatments B0J100, B75J25 and B50J50 had the same survival in subset 1, while in subset 2 treatments B100J0 and B75J25 had the same survival. Sex ratio was significantly different between treatments to food conversion. Then the Post Hoc test was carried out, the results of the analysis showed that the B100J0, B75J25, B50J50 and B25J75 treatments in subset 1 were just as good in their food conversion. Whereas in subset 2 the B0J100 treatment was not the same as the other four treatments. Floc content ml/L. Rangeflocs of all treatments within the range of 9.583-10.524 ml/L, were able to contribute in providing food in the rearing medium. The water temperature during the research period, air and water temperatures ranged from 26.89-27.62 °C (ºC). From the results of this research the range of acidity degrees in all treatments was in the range of 6.87-7.04. The DO concentration at the experimental site ranged 5.1-7.8 mg L-1, which is within the acceptable range for aquaculture.

The aim of this research is to analyze the performance of growth and survival of climbing perch (Anabas testudineus Bloch) which was raised in bioflocs and conventional systems. It investigated the difference in the initial size of the fry stocked with climbing perch has effect. The experimental Original Research Article 15 design used in this study was a Factorial Completely Randomized Design (CRD) with 2 factors and 3 replications: Factor A: climbing perch aquaculture Systems; A1: climbing perch in conventional system of; A2: the climbing perch in bioflocs system; Factor B: Initial Size of fry Stocking; B1: fry size 3 ± 0.5cm; B2: fry size 5 ± 0.5cm and B3: fry size 7 ± 0.5cm. The research was conducted for 90 days with daily growth parameters (SGR), weight and length growth, survival rate, food conversion, flocsvolume density (FVD), and main water quality parameters (water temperature, pH, dissolved oxygen and dissolved ammonia).The results showed that the bioflocs system was able to increase the average growth in the range of 12-67% with an average of 29.73% when compared to conventional systems. The highest value for the daily growth rate or Specific Growth Rate (%/day) was for fry with a size of 7 cm in the bioflocs system (8,419%). The fry size of 3 ± 0.5cm in the bioflocs system had the highest difference in standard length (4.33 cm) while the highest average length during maintenance was the seed size of 7 ± 0.5 cm in the bioflocs system. The survival results of climbing perch fish during the study were based on the highest score on the seed size of 3 ± 0.5cm in the bioflocs system. The survival range of the bioflocs system is 94.89-99.67% and that of the conventional system is 82.00-94.26%. Thus the bioflocs system is able to increase survival in the range of 5-14% when compared to conventional systems. The bioflocs system is able to provide better feed efficiency than conventional systems in the range of 34-39%. The average value of floc volume density (FVD) in the bioflocs system is in the range of 5.35-8.16 ml/L, which is still ideal but can still be improved. Water temperature during the study period, air and water temperatures ranged from 28.54 to 28.71 (ºC), the degree of acidity in all treatments was in the range 6.34-7.27, dissolved oxygen levels were in the range 5.77-6.90 mg /L) while the average measurement results for ammonia levels (mg/L) were in the range of 0.49-0.57 mg/L.

The value of catfish production in Indonesia has decreased drastically every year. Increasing stocking density can be a solution to increase production, but it will have a negative impact on decreasing water quality which will also disrupt catfish production. Therefore, it needs to be accompanied by the application of biofloc and aquaponics technology which plays a role in maintaining optimal water quality while providing additional natural feed (floc) which can reduce feed use and reduce water usage. This study aims to increase the production value of sangkuriang catfish through the application of biofloc and aquaponic systems. This research was conducted in October-November 2022 at the Raudhatul Ulum Sakatiga Agribusiness Group, Ogan Ilir Regency. This study was designed using a comparison experiment. The treatments given consisted of P0 (control), P1 (Maintenance of sangkuriang catfish aquaponic biofloc of kale plant), and P2 (Maintenance of Sangkuriang catfish aquaponic biofloc of lettuce plant). The results showed that P2 was the best treatment which resulted in absolute growth in weight and length of 7.18 g and 3.74 cm, survival of 98%, and growth in length of kale of 30.9 cm.Keywords: aquaponics; biofloc; sangkuriang catfish
