Abstract

Giving hormonal from outside is very helpful for successful spawning because it can accelerate the process of gonad development. This study aims to determine the effect of injection of Gonadotropin Releasing Hormone (GnRH) and anti-dopamine at different doses on the gonad maturity level (TKG), Gonado Somatic Index (GSI), and Hepato Somatic Index (HSI) of snakehead fish (Channa striata). This research was conducted for in November at the Wet Fisheries Laboratory, Department of Fisheries, Faculty of Agriculture, Palangka Raya University. The experimental design used was a completely randomized design (CRD) 4 treatments 3 replications. Treatment A dose sign (control), treatment B dose 0,3 ml/kg, treatment C 0,5 ml/kg, treatment D dose 0,7 ml/kg. The results of this study indicated that the highest gonad maturity level (TKG) was found in treatment D with a dose of 0,7 ml/kg, values TKG V. The highest gonado somatic index (GSI) value was obtained in treatment D at a dose of 0,7 ml/kg, values 2,68%. The highest Hepato Somatik Indeks (HSI) value was obtained in treatment D at a dose of 0,3 ml/kg, values 0,95% This study shows that the injection of Gonadotropin Releasing Hormone (GnRH) and anti-dopamine affects the gonad maturity level (TKG), Gonado Somatic Index (GSI), and Hepato Somatic Index (HSI) of snakehead fish (Channa striata). Keywords: GnRH-a, TKG, GSI, HSI

Abstract

This study aimed to evaluated the growth performance of dumbo catfish (Clarias gariepinus). In this study, ant nest tuber extract and probiotic Lacticaseibacillus paracasei were mixed into feed with the coated method without the addition of ant nest tuber extract and probiotic Lacticaseibacillus paracasei (A), 1% ant nest tuber extract (B), probiotic Lacticaseibacillus paracasei 1% (C). and a combination of ant nest tuber extract and probiotic Lacticaseibacillus paracasei each 1% (D). Fish with an initial body weight of 1.5 - 2 g were kept in 3 ponds (15x10x1.5) m3 with a total of 12 hapa nets measuring 1x1x1 (m3) (45 fish / hapa nets). Fish were fed treatment with three replications for 35 days. The best feed efficiency, feed conversion ratio, daily growth rate and absolute weight growth were found in the African catfish fry group that consumed a combination of feed supplementation with 1% dose of ant nest tuber extract and 1% dose of probiotic Lacticaseibacillus paracasei, each of 185.47%. , 0,55,7,79%, and 20,80 gr

Abstract

Penelitian ini bertujuan untuk mengevaluasi biomassa maggot BSF (Hermetia illucens) yang dihasilkan dari pemanfaatan batang pisang (Musa paradisiaca L.). Penelitian ini dilakukan selama 21 hari bertempat di Laboratorium Program Studi Budidaya Perairan Jurusan Perikanan UPR. Metode penelitian ini menggunakan Rancangan Acak Lengkap (RAL). Adapun perlakuan yang diamati adalah : Perlakuan A= 160 g ampas tahu, perlakuan B = 120 g ampas tahu + 40 g batang pisang fermentasi, perlakuan C = 80 g ampas tahu + 80 g batang pisang permentasi, dan perlakuan D = 40 g ampas tahu + 120 g batang pisang fermentasi. Dalam waktu kurang lebih 4 - 5 hari telur BSF akan menetas menjadi maggot. Berdasarkan hasil penelitian bahwa kombinasi pemberian pakan ampas tahu dan batang pisang fermentasi berpengaruh nyata pada biomassa maggot BSF dengan biomassa rata-rata dan populasi rata-rata tertinggi pada pemberian ampas tahu 100% (perlakuan A) masing-masing yaitu 4,2 kg/m2 dan 3,3 juta ind/m2. Penggunaan batang pisang fermentasi direkomendasikan hanya 25% dari total media.

Abstract

The activity of cultivating nile tilapia in a stagnant water pond system allows fish to utilize resources in the form of natural food and commercial feed in a balanced manner, thereby reducing the amount of external feed. This research aims to evaluate the growth performance of tilapia fry in a stagnant water pond system with different feeding levels. This research was carried out using a completely randomized design (CRD) consisting of 3 treatments for rearing tilapia fry in a stagnant water pond system with different feeding levels with three replications each, namely 3% feeding rate, 4.5% feeding rate. % and feeding rate 6%. The test tilapia fish had an average initial weight of 2.66-3.06 g and were reared for 21 days with feed supplementation containing a commercial probiotic mix dose of 0.2% and a feeding frequency of 1 time per day. The results of the research showed that different levels of feeding had a significant effect (p<0.05) on feed efficiency, feed conversion ratio and amount of feed consumption, but could still provide optimum growth rates.
