Development of high efficient moist pellet (HEMP) diet for flounder paralichthy olivacueus Ⅱ. Availabilrity evaluation of five different commercial compound meals as diettary ingredients

The feeding trials were conducted to investigate availability of five different commercial compound meal (CCM) supplemented to a moist pellet (MP) containing raw fish used in practical aquaculture places; qualities of different CCMs used commely in present mariculture were evaluated through these feeding trials. The 9-week feeding trial was conducted to investigate the effects of MPs containing five different CCMs for flounder on growth and body composition of fish. The 19g juvenile flounder grew to 72.1~87.8g after 9-week. Percent weight gain of fish fed various CCM MPs ranged from 281.5% to 357.3%; The MP containing CCM of A Co. produced significantly greater weight gain than the other diet (B, C, D and E Co.). Feed efficiency values were highest (81.1%) in the MP containing CCM of A Co. and followed by the MP (79.4%) containing CCM of B Co. and then, MPs (67.6~72.5%) from the other company. In total feed comsumption, fish fed MPs containing CCM of A Co. had also the greatest consumption; therefore, the CCM of A Co. considered as having a remarkable feed attractability. According to the result of this study, the CCM of A Co. produced greater weight gain, feed efficiency and feed consumption than the other company’s CCMs.
