Abstract

Bahan kimia sering digunakan sebagai desinfektan untuk pengendalian infeksi parasit, bakteri dan jamur pada ikan budidaya. Penelitian ini bertujuan untuk mengetahui dosis  cupri sulfat (CuSO4) yang efektif terhadap infeksi lintah laut (Zeylanicobdella arugamensis) pada ikan kerapu hibrida cantang (Epinephelus fuscogutattus x E. lanceolatus). Ikan kerapu hibrida cantang (panjang total 11,9±0,83 cm, dan berat 26,43±6,70 g) diinfeksikan dengan lintah laut melalui metode kohabitasi selama 1 bulan. Masing-masing sebanyak 10 ekor ikan sakit direndam dengan larutan CuSO4 dalam air laut dengan dosis 0, 25, 50, 75, 100 dan 150 ppm. Sebanyak 10 ekor ikan lainnya direndam dalam air tawar sebagai pembanding. Perendaman dilakukan selama 30 dan 60 menit dalam bak plastik dengan volume air 10 liter yang dilengkapi dengan aerasi. Masing-masing perlakuan menggunakan dua  buah bak plastik dengan 5 ekor ikan sakit/bak. Hasil penelitian menunjukkan bahwa CuSO4 dosis 100 dan 150 ppm mampu melepaskan dan membunuh lintah laut yang menginfeksi ikan kerapu hibrida cantang dengan prevalensi 30% dan intensitas mencapai 0,40±0,73-0,30±0,50 setelah perendaman selama 30 menit. Prevalensi dan intensitas tersebut menurun hingga 0% setelah perendaman selama 60 menit.  Prevalensi dan intensitas lintah laut dengan perendaman CuSO4 dosis 100-150 ppm lebih kecil dibandingkan dengan perendaman CuSO4 dosis 25-75 ppm dan air tawar. Sintasan ikan setelah perlakuan dan satu hari dipelihara dalam air laut mencapai 100% di semua perlakuan.  Dari hasil tersebut dapat disimpulkan bahwa CuSO4 dosis 100-150 ppm efektif untuk pengendalian infeksi lintah laut pada ikan kerapu hibrida cantang dan dapat menjadi alternatif bahan kimia anti lintah laut pengganti air tawar.

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. Keywords: hatchery, eggs grouper, transportation.

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

Budidaya ikan kerapu sudah berkembang pesat di Indonesia. Beberapa tahun belakangan mulai berkembang jenis kerapu hibrida, antara lain kerapu hibrida cantik. Salah satu kendala dalam pembenihan ikan kerapu hibrida cantik adalah terjadinya serangan penyakit yang menyebabkan sirip ekor ikan jadi buntung. Penyakit ini biasanya disebabkan oleh infeksi bakteri. Penelitian ini bertujuan untuk mendapatkan isolat bakteri dari ekor larva ikan kerapu hibrida cantik dan mengetahui karakteristiknya. Dari hasil isolasi didapatkan empat  isolat bakteri murni dimana dua isolat tumbuh baik pada media cytophaga agar  membentuk koloni berwarna keputih-putihan dan dua isolat lainnya tumbuh baik pada media TCBS agar membentuk koloni berwarna hijau. Isolat bakteri 1 dan 2 sensitif terhadap antibiotik chloramphenicol dan oxytetracyclin tetapi resisten terhadap antibiotik  ampicillin, novobiocin, erythromycin, streptomycin, dan penicillin. Di pihak lain, isolat bakteri 3 dan 4 hanya sensitif terhadap antibiotik chloramphenicol. Nilai konsentrasi hambat minimum antibiotik oxytetracyclin terhadap bakteri isolat 1 dan 2 adalah 62,5 mg/L, dan terhadap isolat 3 dan 4 adalah 250 mg/L. Antibiotik erysanbe 500 tidak efektif menghambat pertumbuhan keempat bakteri uji sampai konsentrasi 1000 mg/L. Konsentrasi hambat minimum antibiotik inrofloxs-25 untuk bakteri isolat 1 dan 2 adalah 31,2 mg/L, sedangkan untuk bakteri isolat 3 adalah 62,5 mg/L dan untuk bakteri isolat 4 adalah 15,6 mg/L.
