Abstract

Identification of Gouramy is required to obtain phenotype characteristics information of the population for sustainable aquaculture  practices. In this study phenotype diversity of giant gouramy strain bastar and bluesafir was analyzed based on  meristic and morphometric measurement. Sample, are taken from 30 individuals of each population. The result showed that there were differences in colour patterns between the two populations, bastar population had yellowish brown body and red fins, whilst bluesafir population had brown blackish brown body and fins. The canonical function of truss morphometric analysis on 21 characteristics showed the measurement distribution of that both populations were in different quadrants. The intrapopulation similarity index showed that population of strain bluesafir had higher genetic similarity (80%) with interpopulation similarity index of 23.3%, while the intrapopulation similarity index of strain bastar was 76.7%.

Abstract

National fisheries production is not proportional to the increase of the population now, so that the consumption of animal protein needs are not met.For the sake of national fisheries production there is a need for intensive cultivation technology breakthroughs to spur the density in nursery phase ‘rajadanu’ carp (Cyprinus carpio) strain. This experiment aim to determine the appropriate density of rajadanu carp growth in the pond at the nursery phase. The average length of tested fishes is 2.02 cm and the average initial weight is 0.25 g maintained in the out door plot pool of Research Installation for Germ Plasm of the Research and Development Division of Freshwater Fisheries, Cijeruk, Bogor measuring 1x1x1 m with density 100, 150 and 200 fishes/m3 .Each treatment was repeated 3 times. Feed used was a commercial feed containing 28% protein given in 2 times a day as much as 5% of the total weight of fish. The results showed that after 40 days, each treatment showed no significant difference (P> 0.05) with absolute length and weight growth of the absolute highest in nursery density of 200 fishes/m3 of 1.30 ± 0.10 cm and 1.14 ± 0, 18 cm with a daily growth rate of 1.30 ± 0.10% and 4.08 ± 0.55%, and the highest survival at densities 200 fishes/m3 of 92.5 ± 6.55%.

Abstract

Fish of Tor genus have a slow growth character that resulted in increasing production cost. The high production cost is related to the high price of feed. Fish growth can be triggered by an optimal feeding. A feeding strategy is needed to improve the efficiency of production cost. This study aimed to determine the profitability and the performance of the seedling thai mahseer fish with different feeding frequencies. This study was conducted in Germplasm Research Station, Cijeruk in March-April 2014. The fish used in the experiment have a standard length of 2.29 ± 0.12 cm and weight of 0.32 ± 0.07 g derived from induced breeding spawning of the broodstock natural catches which was adapted for four years in pond concrete. The fish were reared in the aquarium (dimension= 40 x 30 x 30 cm) with a water height of 20 cm and a stocking density of 50 individuals each. The experiment was designed by using three treatments and three replications for each treatment. Fish were feed using commercial feed (protein content = 28%) as much as 20% per day of the total biomass. The treatment observed was feeding frequency, namely (A) three times/day, (B) twice/day, (C) once/day. Results of the experiment for 40 days showed that the increasing values of length, weight, specific growth rate, survival rate, biomass and FCR were not significantly difference (P>0.05). The highest benefit value was obtained in the treatment of feeding with a frequency of three times/day (Rp. 332.304 ± 14.819,-).

Abstract

Salah satu komoditas ikan air tawar di Indonesia yang memiliki prospek untuk budidaya adalah ikan baung (Hemibagrus nemurus). Namun, teknologi budidaya ikan baung masih perlu disempurnakan, khususnya perbenihannya untuk meningkatkan produktivitas budidaya ikan baung. Salah satu teknologi yang dapat dikembangkan adalah melalui teknik penetasan telur. Penelitian ini bertujuan untuk meningkatkan derajat penetasan dan sintasan larva ikan baung melalui dua sistem penetasan yang berbeda. Penelitian dilakukan di Instalasi Riset Plasma Nutfah Perikanan Air Tawar, Cijeruk, Bogor pada bulan Agustus 2017. Telur diperoleh dari induk ikan baung generasi kedua hasil domestikasi (Bobot induk betina: 443,3 ± 70,9 g; Bobot induk jantan: 486,7 ± 83,3 g). Metode penetasan yang diuji yaitu sistem baki (tray) dan corong (funnel) dengan masing-masing sistem penetasan terdiri dari empat ulangan. Parameter yang diamati adalah waktu penetasan, derajat penetasan dan sintasan larva selama dua hari. Pengukuran kualitas air yang diamati meliputi suhu, oksigen terlarut, dan pH. Hasil penelitian menunjukkan bahwa pada kisaran suhu yang sama, larva menetas pertama kali saat 34 jam setelah pembuahan pada sistem corong. Sementara itu pada sistem baki, larva pertama kali menetas saat 36 jam setelah pembuahan. Derajat penetasan pada sistem corong (65,79 ± 5,49 %) lebih tinggi dibandingkan pada sistem baki (30,60 ± 1,91 %) (P<0,05). Sintasan larva ikan baung selama dua hari tidak berbeda nyata antar sistem penetasan. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa sistem penetasan pada corong menghasilkan waktu penetasan telur dua jam lebih cepat dan derajat penetasan yang lebih tinggi dibandingkan sistem baki.

The aim of this study was to determine the character of reproductive performance and the value of heterosis from cross-breeding of giant gouramy (Osphronemus gouramy) strain Bastar and Bluesafir. Crosses were performed in both directions (reciprocal) with naturally spawning system. Two pairs of giant gouramy of each strain were used, each pair contained 4 ? and 1 ?. Every pairs were reared in 3 x 3 m of pond.Reproductive characterization, such as Fecundity, Ovo Somatic Index, egg diameter, egg weight, Fertilization Rate (FR), Hatching Rate (HR), the latency time of hatching, and yolk sack absorbtion period, were observed. Other parameters including larval lenght and Survival Rate (SR) were also observed. Heterosis (H) value was calculated from FR, HR and SR. Result showed that each population and its cross-breed had no different in reproductive characters. Latency time of hatching, egg diameter, egg weight and yolk sac absorbtion period values were 3 ± 0 days; 0.74 ± 0.05 cm; 11 ± 4 mg dan 9 ± 1 days, respectively. Meanwhile fecundity value showed that Blusafir strain had higher fecundity (3661 ± 624), and Ovo Somatic Index percentage (21.96 ± 3.74). The highest HR was presented by ? Bluesafir x ? Bastar (97.95 ± 0.47 %), meanwhile ? Bastar x ? Bluesafir presented the highest FR and SR (99.15 ± 0.34 % and 92.57 ± 0.40 %). Heterosis value showed that cross-breeding between ? Bastar x ? Bluesafir had better HR and SR (1.20 and 2.37), white hand cross-breeding between ? Bluesafir x ? Bastar presented better FR (0.69).

Abstract

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.

Abstract

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.

Abstract

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.
