This research aimed to obtain information on the variability of crossbred resulted from three stocks of red claw (Cherax quadricarinatus von Martens). This research was performed at Research and Develepment Institute for Freshwater Aquaculture.Nine population consists of tree true breed and six reciprocal breed were resulted from the crossbreeding between the three stocks from Jakarta, Bali and Sukabumi.Results showed that the crossbred between Bali female parent and Jakarta male parent had the highest number of larvae / kg weight of female parent compared to the other crossbred. Between the female parent category, the Bali female parent showed the highest number of the larvae yielded, and between the male parent category, the Sukabumi male parent did. There was no significant different between the crossbred on the respon of growth performance. The highest heterosis on the number of larvae was achieved by the crossbred between Bali and Jakarta (25.8%) while the crossbred between Bali and Sukabumi performed the negative heterosis (-17.6%).Based on the calculation of the number larvae per kilogram weight of the parent, the highest heterosis was achieved by the crossbred Bali-Sukabumi (98.4%).The heterosis on the final weight and length showed the poor result, while on the respon of the specific growth rate showed negative result.It can be concluded that this undertaken hybridization did not provided the significant positive heterosis effect except for the number of larva per unit weight of parent.

Proper stocking density on larval rearing of barred loach (Nemacheilus fasciatus Valenciennes, 1846) is very important in terms of obtaining the best growth and survival rate. This study was aimed to observe the growth and survival rate of barred loach subjected to different larval stocking density. Fish larvae were obtained by artificial spawning from in aquarium. Larvae were stocked on aquariums (50 × 40 × 30 cm) with three stocking density treatments (5, 10, and 15 individuals/L) and three replications. The experimental fish larvae were fed by Artemia and commercial feed (crude protein content: 30%) and feeding frequency twice per day (ad libitum). The length and weight were reassured every 10 days during 70 days of rearing period. Temperature, pH, and dissolved oxygen were measured at each treatment. Data obtained from measurements were analysed to assess the length gain, weight gain, specific growth rate (SGR), biomass gain, and survival rate. The results showed length gain of 3.35 ± 0.01, 2.94 ± 0.10, and 2.82 ± 0.15 cm and weight gain of 0.573 ± 0.023, 0.436 ± 0.018, and 0.417 ± 0.043 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Specific growth rates and biomass growth were of 6.22 ± 0.41, 5.93 ± 0.21, and 5.68 ± 0.41 %/day and 94.04 ± 5.39, 146.80 ± 3.81, and 167.24 ± 17.48 g in larval stocking density of 5, 10 and 15 individuals/L, respectively. Meanwhile, the survival rates obtained in this study were 89.13 ± 7.25, 93.13 ± 5.13, and 76.50 ± 3.54 % in larval stocking density of 5, 10 and 15 individuals/L, respectively. Increased stocking density has a negative impact on the growth and survival rate of barred loach.

Tinfoil barb Barbonymus schwanenfeldii is recognized as one of the potential aquaculture commodities in Indonesia. Nonetheless, lack of data on their environmental tolerance causing this issue to become essential to be investigated. The present study was carried out to assess the pH influence on growth and physiological response of juvenile tinfoil barb. Juvenile tinfoil barbs (TL: 5.5 ± 0.8 cm; BW: 2.4 ± 1.0 g) were treated with four pH level treatments (5, 6, 7, and 8) and three replications with the stocking density of 10 fish each aquarium. Fish were kept for 21 days and fed with commercial fish feed. In this study, pH 8 exposure resulted to lower growth of juvenile tinfoil barb compared to pH treatment 5 to 7 (p<0.05). In terms of survival rate, the results show significantly lower value at pH 8 treatment compared to those of pH 6 and 7 treatment (p<0.05), while it is not significantly different with pH 5 treatment (p>0.05). Additionally, this study found the highest value of glucose, cortisol, and aspartate aminotransferase (AST) on pH 8 treatment (p<0.05). On the other hand, pH 8 exposure led to the lowest creatinine, blood urea nitrogen (BUN), and ALP level (p<0.05). In conclusion, the optimal pH for juvenile tinfoil barb rearing ranged around 6-7.

Tinfoil barb, Barbonymus schwanenfeldii (Bleeker, 1854), is a potential freshwater fish for Indonesian aquaculture. Before widely used, the candidate needs to be evaluated. This research aimed to evaluate the reproductive performance of the first generation (G1) and larval performance of the second generation (G2) of domesticated tinfoil barb. A total of 68 female and 24 male broodstocks were selected for the artificial breeding program. The gonadal maturity test was carried out by canulating the eggs every month. Before spawning, GnRHa hormone was injected into the dorsal area (0.5 mL/kg for female and 0.2 mL/kg for male). Fecundity, fertility rate, hatching rate, embryogenesis, and larvae ontogeny were recorded. The results showed that the first matured G1 males of tinfoil barb were at the standard length of 16.01 ± 1.18 cm, while females at 15.79 ± 1.23 cm. The mature broodstock indicated by the gonad maturity stage III and IV confirming higher estradiol concentration (above 400 pg mL-1). The fecundity of two mature broodstock-sized of 217.2 g and 197.3 g were 12,495 and 15,782 eggs, respectively. The spawning season of G1 tinfoil barb was in October and November (rainy seasons). The fertilized eggs latency time was 10 hours 44 minutes at 25°C and hatched after 23 hours 7 minutes. The fertility rate was 96.96 % and the hatching rate was 95.16 %. The survival rate of G2 normal larvae was 100 % at three days of the rearing period. The G2 larvae production in this experiment provides an excellent opportunity for fish diversification both for aquaculture and restocking.

Hypoxia is one of the critical issues in aquaculture production systems as it can lead to physiological disturbances in cultured fish. This research aimed to evaluate the tolerance level and physiological responses of domesticated Asian redtail catfish Hemibagrus nemurus reared in various hypoxia conditions. A total of 12 fish/treatment were acclimated to gradually decreased dissolved oxygen treatments until fish experienced aquatic surface respiratory (ASR) and loss of equilibrium (LOE). Cortisol, haemoglobin, and glucose levels were detected in the blood plasma to evaluate the stress response of the fish to hypoxia. The result showed that ASR of H. nemurus was identified at 2.17 ± 0.14 ppm of dissolved oxygen (DO) concentration with the percentage of ASR was 77.67 ± 9.53%, while LOE critical of H. nemurus happened at 0.63 ± 0.15 ppm of DO where 55.56 ± 4.81% of the fish experienced LOE. There were significant differences in the values of physiological parameters (blood cortisol, haemoglobin, and glucose) between control and treatments as fish experienced LOE (P<0.05). In the present study, it was found that the Asian redtail catfish is classified as a hypoxia-sensitive fish group. Tehis finding is valuable information for the rearing and growing of the fish to provide an optimal DO concentration for their growth and survival.

Tor soro is one of the most economically important native freshwater fish species in Indonesia. Nonetheless, the insufficient data regarding its salinity tolerance makes a thorough investigation of this issue imperative. This research was conducted to determine the effects of salinity on the growth and physiological response of Tor soro juveniles at optimum salinity levels. This study used Tor soro (total length: 5.0±0.08 cm; initial weight: 2.0 ± 0.06 g) with five salinity level treatments of, 0, 2, 4, 6, and 8 ppt, and the stocking density of 15 fish per aquarium (three replications). Fish were maintained for 30 days and fed with commercial aquafeed. In this study, the best growth was found in 2 ppt (length gain: 0.37 ± 0.05 cm; weight gain: 0.23 ± 0.01 g; specific growth rate in length: 1.38 ± 0.16 % day-1; specific growth rate in weight: 0.78 ± 0.05% day-1) which is significantly higher than 4, 6, and 8 ppt (p<0.05), but it is not significantly different from 0 ppt (p>0.05). The results of the physiological response showed that there were no significant stress responses in Tor soro juvenile for all salinity treatments (p>0.05). there was no effect of 2 ppt salinity on the growth parameters compared to controls, but salinities above ppt had a significant detrimental effect. Exposure to salinities did not have any stress effect as shown by physiological indicators.
