The attractiveness of crude feed ingredients to olive flounder and effects of including feed ingredients showing strong feeding attractiveness in extruded pellet (EP) on performance of fish were determined. Four types of experimental EP were prepared to evaluate the effects of feed ingredient manipulation on performance of fish. Five per cent anchovy meal component of the control diet was substituted with an equal amount of jack mackerel meal, sardine meal and hydrolysed fish meal to create the JM, SM and HFM diets respectively. The diets were prepared in commercial form as EP. Jack mackerel meal produced the strongest feeding attractant responses of olive flounder, followed by sardine meal and hydrolysed fish meal. The greatest weight gain, feed consumption and condition factor (CF) were observed in fish fed the JM diet, followed by fish fed the SM, HFM and control diets, in that order in the 8‐week feeding trial. The dietary manipulation of feed ingredients performed in this study showed that the inclusion of ingredients with strong feeding attractiveness improved feed consumption and eventually accelerated the growth performance and CF of the fish.

各种粗饲料原料对少年比目鱼的吸引力（Paralichthys olivaceus，Temminck＆Schlegel）及其在水产养殖中的应用

确定了粗饲料成分对橄榄比目鱼的吸引力，以及在膨化颗粒（EP）中加入显示出强饲喂吸引力的饲料成分对鱼类生长的影响。准备了四种类型的实验性EP，以评估饲料成分操作对鱼类生长的影响。用等量的鲭鱼粉，沙丁鱼粉和水解鱼粉代替对照日粮中5％的cho鱼粉成分，分别制成JM，SM和HFM日粮。饮食以商业形式如EP制备。鲭鱼粗粉对比目鱼产生最强的诱食反应，其次是沙丁鱼粉和水解鱼粉。在饲喂JM日粮的鱼中，增重，饲料消耗和条件因子（CF）最高，然后在8周的饲养试验中，依次按顺序喂食SM，HFM和对照日粮。在这项研究中进行的饲料成分的饮食操作表明，加入具有强烈饲料吸引力的成分可以改善饲料消耗，并最终加速鱼的生长性能和CF。
