Abstract

Snakehead is a kind of fresh water fish that still taken from the nature, which is the yield of it fishing are unreliable. Therefore, the aquaculture technique is needed. Critical phase of snakehead aquaculture is choosing suitable feed for larvae. Based on this problem, information about first feed suitable for larvae is very important.The aim of the research is to know about growth and survival rate of snakehead larvae with different feed. The research was done in 21 days at the Center for Research and Development of Freshwater Aquaculture Bogor. Larvae with first weight 0.4±0.07 mg and length 4.56±0.53 mm were used. Fish were feed three times daily in ad satiation. Experimental design used was completely randomized design four treatment with three replications, namely A (egg yolk chicken), B (Moina sp,), C (Artemia sp.) and D (silk worm). Parameters measured were the absolute length growth, the growth of absolute weight, specific growth rate, survival rate and feed efficiency. Water quality parameters were temperature, pH, DO and conductivity. The result showed that the used of silk worm as first feed for larvae indicated the best performences. The growth of the absolute length of 13.34±1.30 mm, absolute weight of 54.52±2.93mg, specific growth rate 23.85±0.21%, survival rate 97.67±2.36% and feed efficiency 82.69±7.79%. Keywords : feed, growth, larvae, silk worm, snakehead, survival rate.

Summary

METODE PENELITIAN

Penelitian dilaksanakan selama 21 hari pada bulan Juni sampai dengan Juli 2016 di Laboratorium Basah Nutrisi dan Teknologi Pakan, Balai Penelitian dan Pengembangan Budidaya Air Tawar (BPPBAT) Bogor. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan yaitu perbedaan jenis pakan dan masing-masing perlakuan diulang sebanyak tiga kali. Larva dengan bobot awal 0,4±0,07 mg dan panjang awal 4,56±0,53 mm dengan padat tebar 15 ekor/liter. Dan cacing sutera selama 14 hari kemudian diganti dengan pakan pelet dengan protein 40% sampai umur 21 hari. Pemberian pakan dilakukan secara sekenyangnya pada pukul 08.00, 12.00 dan 16.00 WIB. Parameter yang diuji yaitu pertumbuhan panjang mutlak, pertumbuhan bobot mutlak, laju pertumbuhan spesifik, sintasan dan efisiensi pakan (Effendi, 1997). Sedangkan parameter kualitas air yang diukur yaitu suhu, pH, DO dan konduktivitas (Boyd, 1988). Parameter uji dianalisis secara statistik dengan menggunakan ANOVA (Analysis of Variance) dengan selang kepercayaan 95%. Data kualitas air yang diperoleh dari hasil pengamatan disajikan dalam bentuk tabulasi atau grafik dan dianalisis secara deskriptif. Data diolah dengan menggunakan Microsoft Excel 2010 dan SPSS versi 23
