Abstract

Several types of grouper hybrid seeds can now be massively produced in a hatchery. Hybrid seeds can increase diversification of aquaculture species and potential to increase fish production.  Therefore, an  improvement in hybrid seed production both in high quantity and quality is very important. This research was conducted to produce massively cantik grouper hybrid seeds i.e.,a crossbreed between female tiger grouper (Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon). This research examined the cantik grouper seed production compared with the production of tiger grouper and marbled grouper fingerlings. The research results showed that cantik hybrid grouper seeds production had higher survival rate (24.59%) than tiger grouper (17.44%) and marbled grouper (4.63%). The total length of the seed at the age of 45 days for cantik grouper  was 3.59 ± 0.21 cm, tiger 3.24 ± 0.55 cm, and batik 2.61 ± 0.42 cm, respectively. Seed abnormality for cantik grouper was 4.13%, tiger grouper 30.21%, and marled tiger 0.57%, respectively. Based on genetic variation analyses, the cantik grouper had a closer genetic relationship with the marbled grouper compared with the tiger grouper.

Abstract

The grouper hatchery technology  has been successfully developed and grouper seed can be produced massively and sustainly. Egg is one of key successes in the hatchery processes. Eggs taken from hatchery egg producer were often far away from a final hatchery location. This study tried to find out the effectiveness of eggs transportation  duration and densities for eggs? hatchability of tiger grouper (Epinephelus fuscoguttatus). The first treatment: eggs at a density of 400 000 eggs/8 l sea water,  transported with different duration time i.e., 6,  12, 18, and 24 hours. The second treatment: transportation eggs with duration 24-hour  at different density i.e., 100,000; 200,000;300,00; and 400,000 eggs/8 l sea waters.  Eggs were packaged  in a plastic bag with 8 liters of water media, the plastic size 100 cm x 55 cm, ratio water with oxygen was 1: 3, the  plastic bag inserted to sterofoam with size 75 cm x 40 cm x 30 cm, to reduce the temperature in sterofoam was added ice the size of 500 grams , wrapped in newspaper,  styrofoam  covered by selotipe. The results showed that eggs with transportation time  of 6 and 12 hours were better and significantly different (P <0.05) than  transportation time of 18 and 24 hours. Furthermore, density of 100,000 and 200,000 eggs/8 l sea waters were better and significantly different (P <0.05) than that density of 300,000 and 400,000 eggs/8 l sea waters.

Abstract

ABSTRACT Some researches on grouper seed production have been conducted and their results have been adopted by the farmer. Currently, grouper seeds for mariculture purposes can be provided from hatchery. However, seed abnormality is still the major problem in the hatchery.  Therefore, an improvement for survival rate and quality of grouper seed production is very important. The aim of this study was to improve the production and reduce the abnormalities on grouper seed stock through enrichment of larvae feed (rotifer and artemia) with DHA and EPA, Vitamin and Calcium. The larvae of humpback grouper (Cromileptes altivelis) were reared with and without enrichment. The experiment were held in concrete tank with volume of 10 m3 filled with sea water 7-8 m3. Grouper eggs were stocked at a density of 10 eggs/l, larval were reared until the juvenile age of 45 days.  Treatment were repeated three times. The data was analysed with descriptive statistic. The results showed that humpback grouper larvae reared with enriched rotifers and artemia produced better survival rate (26.81%), lower seed abnormality (26.10%), and better percentage of bigger size of seeds with grade A (20.3 %), B (39.2%), and C (40.5%).  Meanwhile, treatment without feed enrichment produced lower survival rate (17.57%), higher abnormality (40.20%), and lower percentage of big size of seeds with grade A (9.7%), B (26.0%), and C (64.3%).

Abstract

Indonesia is an archipelagic country with many locations suit for aquaculture. Grouper hatcheries are still concentrated in a few locations. Therefore, appropriate technology to transport live grouper seed is needed to ensure the survival and health of the seed. This study aimed to determine the duration of fasting before transportation and the optimum density of grouper seed during transportation. Transportation was conducted in closed system, transported using a car, for 24 hours. Grouper seed used for the experiment was cantik hybrid grouper, a cross-breed between female tiger grouper (Epinephelus fuscoguttatus) and male marbled grouper (Epinephelus microdon) with an average of size 7.0±0.32 cm. There were 2 experiments in this study. Experiment 1 was different durations of fasting before transprotation: A. 12 hours, B. 24 hours, C. 36 hours and D. 48 hours with the density of 150 seeds/boxes. The result of the first experiment was used to determine the experimental design of experiment 2, which consisted of 4 different densities per boxes: A. 125 seeds, B. 150 seeds, C. 175 seeds and D. 200 seeds. Both of the experiments were conducted in triplicates. The seeds were packed in plastic bags with a thickness 0.08 mm, length 120 cm x width 53 cm, filled with 10 liters of sea water. The results showed that the duration of fasting from 36 to 48 hours had the highest survival rate. Polinomial relation y = -0.0439x2 + 3.7696x + 17.075 with the value of R² = 0.966 illustrated that the optimum duration of fasting was 44 hours. There was a significant difference in densities of seeds during transportation (P<0.05), where the higher density lead to the lower survival rate. The density of 125 seeds/boxes resulted in the highest survival rate, 99.0 ± 1.0%.
