Physiological response and quality of red tilapia Oreochromis sp. in the culture system using lemna (Lemna perpussila) as phytoremediator

Abstract

This study used Lemna as phytoremediator plant in red tilapia culture system and given as feed additive among treatments. The purpose of this study was to measure the production performance (quantity and quality) and physiological response of red tilapia. Study was conducted with two treatments: TL (without lemna) and L (with lemna) treatment. The results showed that L treatment gave the best result based on better feed convertion ratio. However there are no significant difference found in organoleptic test, growth performance, and blood cholersterol parameters. In addition, optimum water quality media that stimulated by lemna, can create a comfortable environmental conditions for red tilapia.
