Abstract

The accumulation of organic compound from waste feed and feces from intensive catfish culture can give negative impact to the water quality. On the other hand, the need of live feed for freshwater fish larvae are not sufficient. The aim of this research was to study the effectivity of intensively catfish culture wastewater as a media for Daphnia sp. culture. The experimental research design was completely randomized with five treatments, i.e: Using 5 g/l of chicken manure in the media culture of Daphnia as a control while treatments B, C, and D were using wastewater of intensively catfish culture. The concentration of wastewater of intensively catfish culture was 25%, 50%, 75%,and each treatment was replicated four times. Broodstock of Daphnia sp. used at least 1mm diameter with stocking density 20 ind / liter. Data on population growth of Daphnia sp. obtained were processed using analysis of variance with confidence interval of 95%, followed by least significant difference test (LSD). Furthermore, water quality parameters and density of plankton was examined as supporting data. The water quality data was observed every 4 days and plankton density observation was conducted at the beginning and the end of the study. The result of this research showed that the wastewater of an intensive catfish culture could be used as an alternative media for Daphnia sp. culture. Based on the analysis showed that the different media of Daphnia sp. culture significantly influenced to the population growth of Daphnia sp. The most effective media for Daphnia sp. culture in this research was treatment C and D i.e. 75 % and 100% of waste water of intensive catfish culture.

Abstract

Ikan patin siam merupakan salah satu ikan budidaya air tawar yang memiliki nilai ekonomis tinggi di Indonesia. Transfer gen pCcBA-PhGH pada ikan patin siam bertujuan untuk mempercepat pertumbuhan dan meningkatkan produksi ikan patin siam. Pada penelitian ini dilakukan evaluasi terhadap tingkat transmisi dan ekspresi fenotipe gen pCcBA-PhGH pada generasi pertama (F1) ikan patin siam. Generasi F1 ikan patin siam supergrowth dihasilkan dengan cara mengawinsilangkan antara induk jantan ikan patin siam yang membawa gen pCcBA-PhGH (ikan patin siam supergrowth generasi F0) dengan induk betina ikan patin siam non-supergrowth. Sebagai populasi kontrol dilakukanpersilangan antara sesama induk jantan dan betina non-supergrowth. Hasil ersilangan antara induk jantan ikan patin siam supergrowth generasi F0 dengan induk betina ikan patin siam non-supergrowth menghasilkan derajat pembuahan (FR) sebesar 78,8±4,85% dan derajat penetasan (HR) sebesar 97,9±0,85% relatif lebih tinggi dibandingkan kontrolnya (FR: 38,5±0,96%; HR: 89,6±3,05%). Tingkat transmisi gen pCcBA-PhGH dari generasi F0 ke generasi F1 adalah sebesar 66,7%. Selama empat bulan pemeliharaan di kolam, populasi ikan patin siam supergrowth generasi F1 tumbuh 47,5% lebih cepat dibandingkan populasi kontrol. Adapun biomassa populasi ikan patin siam supergrowth generasi F1 70,5% lebih tinggi dibandingkan kontrol.

Abstract

Abstrak lengkap dapat dilihat pada Full PDF Program peningkatan mutu genetik melalui seleksi merupakan salah satu upaya dalam memenuhi target produksi ikan patin siam untuk menghasilkan populasi dengan individu unggul. Tujuan penelitian ini adalah untuk mengevaluasi keragaan fenotipe populasi ikan patin siam F-2 sebagai bahan seleksi berdasarkan karakter pertumbuhan.
