Currently, among the 18 assessed Mahseer fish species by the International Union for Conservation of Nature (IUCN), 50% are classified as threatened to critically endangered. However, the T. soro and T. douronensis species, originating from Indonesia are not included in the IUCN Red List [2]. The Mahseer fish population is declining primarily due to the ongoing dependence on wild captures to fulfill consumer demands. Moreover, anthropogenic activities on deforestation, land conversion, and pollution of river or lake can disrupt crucial habitat conditions and environmental quality for Mahseer fish [1]. Addressing this issue necessitates the implementation of cultivation activities

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.

Upaya pencarian sumber-sumber protein alternatif dan optimasi potensinya serta minimalisasi faktor antinutrisinya merupakan hal mendesak yang harus dilakukan. Tepung daun lamtoro (TDL) merupakan salah satu alternatif sumber protein pakan, karena kandungan proteinnya cukup tinggi (24-28%), profil asam aminonya mendekati TBK dan memiliki kandungan vitamin A dan â-karoten yang cukup tinggi. Namun pemakaiannya dalam formulasi pakan ikan dibatasi oleh keberadaan beberapa zat antinutrisi seperti asam fitat, mimosin dan tanin, juga kandungan serat kasar yang cukup tinggi. Perlakuan kombinasi antara perendaman dan pengovenan terbukti dapat menghilangkan kadar mimosin dan tanin TDL hingga 95%, sedangkan asam fitat dapat dikurangi dengan pemberian enzim fitase. Keberhasilan upaya eliminasi zat-zat antinutrisi dalam TDL akan meningkatkan level...
