Effect of Different Types of Commercial Feed Meal on the Growth Forms of Barbonymus schwanenfeldii (Lampam) in Chini Lake, Malaysia

摘要

This study was carried out at Tasik Chini where the effects of different feeds on growth form of B. schwanenfeldii were calculated using length weight relationship analysis (W= aL~b). The results denotes that feeding high protein diet ( 32% protein) fish represent positive allometric growth (b> 3) while feeding lower protein diet (23 and 28% protein) fish represent negative allometric (b < 3) growth. The calculated condition factor values also denotes similar trends, feeding high protein diet fish represent better condition (K=51) compared to fed on lower protein diet. The data obtained from this study suggests to culture B. schwanenfeldii with high protein diet (32%) which will facilitate better growth form and condition consequently optimize the production of this commercially important fish species.
