根据大黄鱼网箱养殖区的实际条件和大黄鱼的营养需求，以提高饲料利用率、促鱼生长、减少环境污染、易制作为目的，将研制的大黄鱼软颗粒干粉料与常用的鲜杂鱼糜以8∶5比例混合，配以0．4％的鱼肝油，通过水产湿颗粒饲料压制机压制成软颗粒饲料，并用A、B、C、D等4种不同成分含量的软颗粒饲料与鲜杂鱼糜分别投喂大黄鱼进行养殖效果比较试验。结果表明：研制的粒径0．4～1．0 cm的软颗粒饲料，圆柱体外观光滑，无开裂现象，切口整齐；保持鲜杂鱼固有风味，无腐败、霉变及其它异味；水中稳定性良好，沉降速度8．3 cm/s；其诱食效果优于鲜杂鱼糜；投喂大黄鱼，其养殖效果及经济效益优于投喂冰鲜饵料，尤其是其中的D组料（相对增重率81．0％，饲料系数1．81），效果尤其显著，可推广使用。

To improve the feed efficiency,hasten the growth, reduce environmental pollution and make the feed easy to manufacture, an experiment was conducted based on the nutritional requirement of the large yellow croaker and the actual cultivation conditions .By mixing the dry powder feed and the common fresh surimi in a ratio of 8∶5, the soft pellet feed was compressed using the pellet feed briquetting machine with a concentration of fish liver oil at 0.4%.Then the fresh surimi and soft pellet feed with different proteins of A#, B#, C#and D#were used to evaluating culture effects .The results indicated that the soft pellet feed had a particle size between 0.4-1 cm and it was free of crack, with a clean cylinder appearance and cut as well .It kept the inherent flavor of the trash fish and no peculiar smell such as moldy and rotten was found .The stability was fine in water with a sedimentation rate of 8.3 cm/s.Compared with the fresh surimi , the soft pellet feed had better effects.Especially the D#, which had an instantaneous growth rate of 81% and a feed coefficient of 1.81, could be treated as a model to promote.
