Abstract This study aimed to determine the effect of different doses of ovaprim on spawning time, egg hatchability, and survival of  African catfish larvae (Clarias gariepinus). The research was done in the Central Local Fish Seed (BBI) Jayapura, Papua Province. Experimental design used was Randomized Complete Design. The study consisted of four treatments namely 0 ml, 0.3 ml, 0.6 ml and 0.9 ml ovaprim, each with three replications. Data collected were spawning time, egg hatchability, and survival rate of African catfish larvae. The number of containers used was as much as 12 buckets (for spawning, hatching, and observation of survival rate of larvae). The results showed that treatment with different doses of ovaprim hormones provided a significant influence on the latency time of spawning, egg hatchability and survival rate of larval. The dose of 0.3 ml ovaprim caould increase the latency time of spawning, egg hatchability and survival rate of African catfish larvae. The average latency time of hatching was 552 minutes,  spawning and  egg hatchability 84.16% and survival rate of  living larvae was 85.76%.

This study was conducted to determine the effect of different doses of ovaprim on latency time of spawning, hatching rate, and survival of fish larvae (Pangasianodon hiphopthalmus). Experimental design used was Randomized Complete Design (CRD) with four treatments, each with three replication. The treatments including 0 ml, 0.3 ml, 0.6 ml and 0.9 ml ovaprim per kg of body weight of fish. Data collected consisted of latency time of spawning, hatching rate, and survival rate of larvae. The results showed that treatment with different doses of ovaprim hormones resulted in a significant influence on latency time of spawning, egg hatchability and survival rate of larvae. It was found that 0.6 ml ovaprim could increase the latency time of spawning, egg hatchability and survival rate of larvae. The average latency time of larvae was 529 minutes, hatching rate was 80,86% and survival rate of larvae was 83,33%.

A study on the effect of different doses of Ovulin hormone suspended in saline on the breeding performance of Clarias anguillaris and Clarias gariepinus was carried out. The experiment was conducted in a 2x5 factorial experiment in a Completely Randomized Design at the Hatchery Unit of the Department of Fisheries and Aquaculture, Usmanu Danfodiyo University, Sokoto. Species and hormone dilutions constituted the factors with specie having 2 levels (C. anguillaris and C. gariepinus) and Ovulin suspended in saline at 5 levels (0%, 25%, 50%, 75% and 100%). The result showed that species levels did not significantly (P>0.05) affect the breeding performance in all the breeding performance parameters observed. However, fertilization rate, hatching rate and survival rate were significantly affected (P<0.05) by different levels of Ovulin suspended in saline, but did not have significant influence (P>0.05) on egg weight, spawning fecundity and relative fecundity. It could be concluded from this study that Ovulin suspended in saline can have significant influence on the breeding performance of African catfish.

This study aimed to determine the effect of ovaprim hormone, aromatase inhibitor and pituitary on the quality of the catfish eggs (Clarias gariepinus). Experimental Design used was Completely Randomized Design (CRD) with four treatments, each with three replications. Treatment A: ovaprim; treatment B: Aromatase inhibitors, treatment C: hypophysis and treatment D: Control. The results showed that the difference in treatment gave highly significant effect on fertilization and hatching eggs but no significant effect on the survival rate of larvae. Aromatase inhibitor hormone was the best because it provided highly significant effect on fertilization (92.66%), hatchability of eggs (95%), and surviva rate (81.33%) of fish larvae.   Keywords : Clarias gariepinus.

Summary The optimum distance and duration of ultraviolet (UV) irradiation for the complete inactivation of African catfish Clarias gariepinus egg nucleus was investigated in this study. The UV light was suspended above the unfertilized eggs at four distances (5, 10, 20 and 30 cm) and for five durations (1, 2, 3, 4 and 5 min). Then, the irradiated eggs were activated with sperm from diploid C. gariepinus and cold shocked at 5°C for 5 min just moments before cell cleavage. Ploidy analysis was performed using karyotype chromosome counting. The results obtained suggested that the further the distance, the better the hatchability rate, however prolonged duration seemed to significantly reduced hatchability. All treatments with surviving progenies at the end of the study showed evidence of successfully diploid gynogen (2n = 56) induction at different percentages. However, the optimal protocol that gave a moderately high hatchability/survival rate and completely induced gynogens was exposure of the eggs to UV irradiation at 20 cm for 1 min. It was concluded that the distance and duration of UV irradiation affects gynogenetic induction in African catfish C. gariepinus.

AbstractThe feed as a source of energy for the growth of fish is a component of the most important costs 40-89% and the quality should be good. The solution is through research. Research in the form of meal cassava leaves (Monihot utilissima) parents as a source of alternative protein substitute for fish meal in feed formulation catfish (Clarias gariepinus). The design used Complete Random Design with 4 treatments and 3 repetitions. The results showed that for the growth and the survival between treatments were not significant (P <0.5), meaning that all treatments were no differences can be categorized and feed ingredients of flour cassava leaves can replace most of the presence of meal fish  in fish feed formulas African catfish. Growth of the best catfish are on treatment A (55% meal cassava leaf: 00% fish meal) with daily growth of 8.27 grams was 2.61% and the B (40%% meal cassava leaves: 15% meal fish) 5.28 gram with daily growth is 1.86%, followed by C (15%%  meal cassava leaves: 15% meal fish ) 1:51% and D (0% meal cassava leaves : 55% meal fish ) 1:33%. Catfish survival rate was not significant (P <0.5), and relatively equally well A (96.17%), B (94.77) and C (95.92) and the best in treatment for D (96.37 ). As users are advised to wear formulations in treatment B (40% meal fish and 15%  meal cassava leaves old). Keywords: Catfish, Ffeed, Meal fish, Meal cassava leaves AbstrakPakan sebagai sumber energi bagi pertumbuhan ikan  merupakan komponen biaya yang paling besar 40-89%  dan kualitasnya harus baik.

Background The objective of the present study was to evaluate the growth performance and feed utilization of African catfish Clarias gariepinus fed a commercial diet and reared in the biofloc system enhanced with probiotic. Methods The treatment was the frequency of probiotic application into the cultured system, namely, 5-day interval, 10-day interval, and 15-day interval for 60 days of experiment. Biofloc culture was grown in an experiment tank (vol. 2000 L) by mixing the probiotic (Bacillus sp.) 10 mL and molasses 200 mL per liter of water.  The fish was stocked into the biofloc system 7 days after cultured at stocking density of 1000 fish tank-1.  The fish was fed a commercial diet that contains 38% crude protein, twice a day at satiation. The application of probiotic was reperformed after 5 days, 10 days, and 15 days after stocking. Results The study showed that the growth performance, survival, and feed utilization of African catfish were higher in the treatment at 5-day intervals over 60 days. The ANOVA test showed that the application frequency of probiotic into biofloc system of cultured media had the significant effect on the growth performance, survival rate, and feed utilization of African catfish. Conclusion The best growth performance and feed utilization were  found at the application of probiotic into biofloc system at 5-day intervals over 60 days.
