The Effects Of Dietary Lipid Level And Source On The Growth And Body Composition Of The Malaysian Mahseer, Tor Tambroides

The Malaysian mahseer, Tor tambroides is regarded as a highly valued fish in the country. Popular among sport fishing enthusiast and serve as a delicacy in many parts of this country, the Malaysian mahseer can fetch a very high price in the market, there is very limited studies on the nutrition, especially lipid studies, on the fish. The present study was conducted to determine the best lipid level inclusion in the fish’s diet and also a follow up study on the effect of different lipid source on the growth and body composition of the Malaysian mahseer

A comparative analysis of the effect of low-cost fish and commercially compounded feed on growth performance and organoleptic quality of hybrid grouper (Epinephelus fuscoguttatus× Epinephelus lanceolatus) in cage farming in Kuala Penyu, Sabah, and nutritional costs

A 25-week feeding trial was conducted to assess the growth performance, organoleptic quality, and to estimate the viability of nourishing hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus) with low-cost fish (LCF) and commercially compound feed (CCF). A group of 3600 juvenile fish (182g) were released in four sea cages and fed with either LCF or CCF in duplicate. At the end of the trial, the hybrid grouper provided LCF attained a significantly higher (P0.05). Although technicalities of fish fed with LCF suggest that LCF is more efficient than CCF, feeding LCF to high-value fish is an unsustainable practice as LCF is usually obtained through trawling –a destructive fishing method for the marine ecosystem. Therefore, feeding with CCF without the use of LCF as the source of protein for its fishmeal will contribute to sustainable aquaculture. In order to convince the local farmers in Sabah to adopt the practice of feeding CCF, future research should focus on completing the species-specific diet formulation to promote optimum growth, and find ways to reduce the CCF local selling price
