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

Fish Tor is one of potential fish commodities to be developed because of their economic value. This on experiment was designed to evaluate the effect of male and female parent on morphological characters i.e length and weight growth and the value of heterosis from crosses of Tor soro and Tor douronensis. Crosses were performed in both directions (reciprocal) to form four populations. Observations lenght, weight gain, specific growth in length, specific growth in weight and value of heterosis were carried out for two months (January-March, 2014). The results showed an increase of  length, weight, specific growth in weight, specific growth in length occurred in seed produced from parent male of T. soro and female of T. douronensis with values of 0.54 cm, 0.09 g, 0.65 % and 3.79 %, rescpectively. Crossed of ? T. douronensis x ? T. soro yield heterosis value (partial) of length (40.90%) and weight (116.66%) was higher than crossed of ? T. soro x ? T. douronensis  that only have heterosis value of 0 and 33.33 %, and heterosis value (reciprocal) on the length of 20.45 % and the weight of 45.22 %.

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

Hybridization is one alternative of genetic improvement to increase the production of commercialize commodity. 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).
