Genetic improvement of the African catfish (Clarias gariepinus) in Indonesia for increasing growth performance has been conducted by Research Institute for Fish Breeding at Sukamandi through mass selection. Collection and characterizations of the founder populations, building the synthetic base population, first generation and second generation through mass selection were conducted during 2010-2013. Later, in 2014 it was followed by building the third generation. The present study aimed to find out the genetic gain in the third generation in term of response to selection for body weight. Fifty-two pairs of the selected (fast growing) individuals from the second generation were mated to produce the third generation. As a comparison, five pairs of average-sized individuals were mated to produce the control population, as a second generation representative. Larval rearing, nursery and grow-out phases were respectively held for 25 days in the aquaria, 30 days in the concrete ponds and 60 days in the concrete ponds. At the end of each phase, individual samplings of body weight were undertaken. The results showed that mean body weight of the third generation was higher than that of control population at the end of larval rearing phase (0.21 ± 0.26 g versus 0.20 ± 0.15 g), nursery phase (6.12 ± 2.93 g versus 5.80 ± 3.50 g) and grow-out phase (198.67 ± 82.82 g versus 165.22 ± 71.09 g). Those results revealed that response to selection for body weight of the third generation was positive, i.e. about 20.24% (33.45 g).

Koi herpesvirus (KHV) is one of the major pathogen for koi and common carp which cause high mortality and economic losses for the farmer. The purpose of this study was to determine the efficacy of glycoprotein-11 (GP-11) KHV DNA vaccine and compared to GP-25 KHV DNA vaccine. The vaccine in the form of naked DNA plasmidwas delivered by intramuscularly injection to the 3-month-old koi. The fish were divided into six groups, i.e. unvaccinated group (negative control C- and positive control C+), and vaccinated group (2.5 μg/100 μl of GP-11 (group 1), 7.5 μg/100 μl of GP-11 (group 2), 12.5 μg/100 μl of GP-11 (group 3), and 12.5 μg/100 μl of GP-25 (group 4)). At day 42 post vaccination, all fish of each groups were challenged by injecting KHV titre 10-3 FID50. Number of dead fish was counted everyday after the challenge until 30 days. The results showed that vaccinated fish were had survival rate of 83.33-93.33% (group 2, 3 and 4). It’s show that GP-11 KHV DNA vaccine has high efficacy. As conclusion, GP-11 DNA vaccine could be an alternative DNA vaccine for preventing KHV infection.

Very low naturally mating rate of pond-reared tiger shrimp broodstock is probably due to the slow maturation of the male stock. The aim of this study was to evaluate the salmon gonadotrophin releasing hormone analoque (sGnRHa) in stimulating the gonadal maturation of male stock of pond-reared tiger shrimp. The treatments were three dosages of sGnRHa at 0.1 (OV-1), 0.2 (OV-2), and 0.3 (OV-3) mL/kg of shrimp weight and control was eye stalk ablation (AB). The sGnRHa was administered via injection three times with one week interval. Male stocks with average initial body weight of 82.1 g were randomly distributed into four of 10 m3 concrete tanks, 26 males for each tank. Variables observed were performances of spermatophores and profiles of amino acid and fatty acid of muscle of the male stocks. After induction, number of male maturing indicated by spermatophores releasing from terminal ampullas was higher in shrimp induced with OV-1 (80.8%) compared to control which was only 46.1%. Furthermore, shrimp treated OV-2 had the highest spermatophore weight of 0.16 g compared to control (0.11 g) and other two groups. Amino acid profiles improved as the dose of sGnRHa increased up to 0.2 mL/kg from 61.23% for ablated male becoming 71.27% for OV-2. Total fatty acid also tended to improve by increasing the dose of hormone injection, however, the ablated male had higher total fatty acid content than that of OV-1. The present finding demonstrated that the dose of sGnRHa to stimulate the gonadal maturation of pond-reared male tiger shrimp could be applied at range between 0.1-0.2 mL/kg of shrimp weight.

Big size betta (Giant) have a high economic value compared to normal size betta, and over expression of growth hormone gene can produce giant fish. As an initial step of giant transgenic betta productions, this study was conducted in order to obtain DNA plasmid concentration which provide higher hatching and survival rate of betta larvae. Construction of PhGH pCcBA gene contains growth hormone gene of Siamese catfish (PhGH) and it is controlled by the CCBA promoter. Betta imbellis broodstocks were spawned naturally, and embryos were collected 1-2 minutes after spawning time. One hundred embryos were dipped in 2 mL of transfectan X-treme gene which containp CcBA-PhGH construction genes (50 µg/mL), on room temperature for about 30 minutes. Treatments on this study were different transfectant : DNA plasmid ratiosnamely:A (0,75 µL: 0,25 µL); B (0,75 µL : 0,50 µL); C (0,75 µL: 0,75 µL), D as Control 1(without transfectant, 0,25 µL DNA); E.as Control 2(0,75 µL transfectant, without DNA), and Fas control 3 (without transfectant and without DNA). Every treatments was repeated three times. Transfection embryos were hatched on a container (1L Volume). Study results showed that hatching rate and larvae survival rate (4 days after hatching) on treatment A were the same with the control, but slightly higher than B and C treatments. PCR analysis with DNA template showing that PhGH gene were found on embryos and larvae (pooled sample) of treatment A, B and C. Furthermore, RT-PCR analysis showing the existence of mRNA PhGH expression on embryos and larvae (pooled sample). Therefore, embryo transfection with transfectant ratio 0,75 µL and DNA 0,25 µLshowing the best results.

Research Institute for Fish Breeding has produced transgenic African catfish (Clarias gariepinus) containing stripped catfish growth hormone gene (PccBA-PhGH) with growth 19.86% faster than that of non-transgenic fish. This fish has high potential to be released and utilized for fish farming sector to increase national production. However, there is not yet information about environmental risk of this fish. One of the major fitness traits determining potential environmental risk is predator avoidance. This study aimed to determine the predator avoidance ability of transgenic African catfish in an experimental laboratory condition. In this study, thirty five individuals each of transgenic and non-transgenic with body weight of about 0.1 ± 0.019 g were communally stocked in 60 cm x 40 cm x 40 cm aquarium with limited feeding frequency (ad libitum twice a day). One day after the fish were stocked, the predators were added to each aquarium. The non-transgenic and transgenic with body weight of 1.0 ± 0.024 g were stocked as predators as many as five individual in each aquarium. After approximately two weeks of predation, all remaining fish were collected for transgenic verification by PCR method. Genomic DNA was isolated from fin tissue of individually survivors. The results of this study showed that the transgenic fish had worse predator avoidance and lower cannibal than non-transgenic (P<0.05). There was no significant difference in growth performance between transgenic and non-transgenic African catfish (P>0.05) in limited food. The transgenic fish may have lower fitness than non-transgenic.

Koi Herpesvirus (KHV) is a malignant virus infecting the goldfish and koi in all stadia and cause mortality up to 95%. The purpose of this study was to determine the potency and efficacy of inactivated-vaccine in addition with adjuvant against KHV in koi fish. The viral propagation was done using a KF-1 cell line in 25 cm3 flask. The cultured virus was harvested on 12 days post inoculation, and then the harvested virus was inactivated with 0.1% formalin as inactivated-vaccine. Three hundred of test fish (10.38 ± 1.25 g) maintained in 126 L of plastic containers with aeration, and fed with pellets twice a day. After 14 days of adaptation, the fish were divided into five treatments (A= vaccine; B= vaccine + Complete Freund’s Adjuvant; C= vaccine + Incomplete Freund’s Adjuvant; K+= positive control, and K-= negative control) and each treatment has four replicates. Vaccine was given by injecting intramuscularly of 0.1 mL per fish. All fish were challenged by injecting intramuscularly of 0.1 mL of KHV virus with concentration of 104.58 TCID50/mL after 21 days post vaccination. The results showed that the B treatment had higher (P<0.05) values of hematocrit level, lysozyme activity, and titer of antibody compared with positive control. In addition, the survival of fish in B treatment also had the highest percentages and significantly different compared to other treatments (P<0.05). The conclusion of this research was the application of inactivated KHV vaccine in 0.1% formalin with the addition of Complete Freund’s Adjuvant through the injection dose 0.1 mL fish-1 in 104.58 TCID50/mL capable to enhance the immune responses and raised the optimal protection of KHV antibody in koi fish.
