Identification of Gouramy is required to obtain phenotype characteristics information of the population for sustainable aquaculture Â practices. In this study phenotype diversity of giant gouramy strain bastar and bluesafir was analyzed based on Â 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%.

Objectives of this study are to determine the genetic variability among progeny of intraspecific crossing between three strains of Oreochromis niloticus Bleeker (BEST, Nirwana, and Red NIFI) using Randomly Amplified Polymorphic DNA (RAPD) and truss morphometric. The results showed that hybridization enabled to increase genetic variability respectedly on progeny of Nirwana male crossed to BEST female (27,93%) as well as to Red NIFI female. An analysist of truss morphometric indicated that BEST population had the lowest similarity and largest genetic distance (0,6) to the Nirwana and Red NIFI which were closer to the hybrid populations.

Objectives of the study was to discover genetic variability and genetic relationship of paternal half sib population of nile tilapia (Oreochromis niloticus) under Selection Program Scheme at Research Institute for Freshwater Aquaculture, in Bogor, West Java.Four populations from unrelated selected breeders were observed for genetic variability using RAPD. The analysis of amplification from each locus and fragments were used to estimate DNA polymorphisms, heterozygosity, fst and genetic distance.The range of heterozygosity of four examined populations was 0.1760-0.2168 with level polymorphic between 47.66% and 64.86%.The highest heterozygosity and polymorphic was on population 1 and the lowest one was on population 2. Fst test showed significance among the populations. The closest relationship was between population 1 and 4 (0.1978) and the furthest was population 2 and 3 (0.3289).

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.
