Abstract

The high cost of fish feed is a main problem in aquaculture industries, and the effort to improve the cost efficiency of feed is the main focus for nutritional research program all over the world. Research is needed to identify less expensive and more sustainable ingredients within fish feeds, while maintaining nutritional quality equal to those based mainly on fish meal and soybean meal. Leucaena leaf meal (LLM) is a potential alternative plant protein source because of its high protein content and low cost compared to soybean meal. The Leucaena leaf was soaked in freshwater for 3 days prior to use. This study was a 60-day trial and aimed to examine the replacement of soybean meal with LLM at various level in practical feed for Nile tilapia. This trial used a Completely Randomized Design which was carried out in 15 aquarias sized of 60 x 60 x 50 cm. Triplicate group of nile tilapia (initial body weight 12,04 ± 0,38 g fish-1 ) were fed five isonitrogenous and isocaloric feeds. The control feed was containing soybean meal, whereas in other four feeds, LLM directly replaced soybean meal with the inclusion level of 8, 16, 24 dan 31 % within the feed formulation. Result showed that the growth performance and feed efficiencies of feed containing 8, 16, 24 and 31 % LLM on the formulation were significantly lower compared to control feed. LLM was able to consumed by nile tilapia although there was a tendency of decrease of the feed consumption with the increase of LLM inclusion. It suggested that the additional treatment is needed to improve the quality of LLM, and to increase the inclusion level of LLM in feed.

Abstract

This research was aimed to determine the optimum level of inclusion of blood flour in feed formulaton of Nile Tilapia as a substitute for fish meal. The materials of this research are a feed and Nile Tilapia with an average weight of 17 g of a total of 120 fingerling. The experiment design has been conducted  were completely random design with 5 treatments and 3 replications. The treatments are the substitution of fish meal with the blood flour of  0%, 25%, 50%, 75%, and 100%. Spesific growth rate, the mount of feed consumption, food efficiency,  survival rate, and water quality has been evaluated.  The results of research showed that spesific growth rate  and food efficiency were significantly different between treatments (P<0.05), and the highest of spesific growth rate  and food efficiency there are on treatment D (the substitution of fish meal with the blood flour of 75%) each 1.75% and 63.45%. The lowest of spesific growth rate  and food efficiency there are on treatment A (the substitution of fish meal with the blood flour of  0%) each 1.42% and 48.98%. The blood fluor as a substitution of fish meal in artificial feed for Nile Tilapia can substitute the fish meal of 100% with level of inclusion of  9% in feed formulation. The combination between the blood fluor and fish meal give the best of  growth performance and feed efficiency. Key words: Nile Tilapia, feed efficiency, survival rate, growth rate

Abstract

Tujuan dari penelitian ini ialah untuk mengetahui level inklusi optimal tepung ikan asin bawah standar dalam formulasi pakan ikan Nila sebagai pengganti tepung ikan. Perlakuan terdiri atas penggunaan tepung ikan asin bawah standar dengan dosis 0%, 4%, 8%, 13%, dan 17%. Laju pertumbuhan spesifik, efisiensi pakan, konsumsi pakan, tingkat kelangsungan hidup, dan kualitas air telah dievaluasi. Kisaran laju pertumbuhan spesifik, konsumsi pakan, efisiensi pakan, dan tingkat kelangsungan hidup adalah 2,50-2,58%, 56,84-60,69%, 292,44-297,45 g, dan 97,78-100,00%. Tepung ikan asin bawah standar sebagai pengganti tepung ikan dalam formulasi pakan dapat mengganti sebanyak 17%. Kata kunci: Tepung ikan asin bawah standar, substitusi, Ikan Nila, pertumbuhan, efisiensi pakan, konsumsi pakan

Abstract

This research aimed to obtain information on the variability of crossbred resulted from three stocks of red claw (Cherax quadricarinatus von Martens). This research was performed at Research and Develepment Institute for Freshwater Aquaculture.Nine population consists of tree true breed and six reciprocal breed were resulted from the crossbreeding between the three stocks from Jakarta, Bali and Sukabumi.Results showed that the crossbred between Bali female parent and Jakarta male parent had the highest number of larvae / kg weight of female parent compared to the other crossbred. Between the female parent category, the Bali female parent showed the highest number of the larvae yielded, and between the male parent category, the Sukabumi male parent did. There was no significant different between the crossbred on the respon of growth performance. The highest heterosis on the number of larvae was achieved by the crossbred between Bali and Jakarta (25.8%) while the crossbred between Bali and Sukabumi performed the negative heterosis (-17.6%).Based on the calculation of the number larvae per kilogram weight of the parent, the highest heterosis was achieved by the crossbred Bali-Sukabumi (98.4%).The heterosis on the final weight and length showed the poor result, while on the respon of the specific growth rate showed negative result.It can be concluded that this undertaken hybridization did not provided the significant positive heterosis effect except for the number of larva per unit weight of parent.
