摘要:
选择冰鲜杂鱼和2个市场反映较好的石斑鱼配合饲料产品,分别对斜带石斑鱼(Epinephelus coioides)进行饲喂效果实验,通过生长性能、体成分、群体离散度以及养殖成本分析,评价冰鲜杂鱼和配合颗粒饲料在斜带石斑鱼养殖效果上的优劣。同一批培育的斜带石斑鱼幼鱼,随机分成3组(冰鲜杂鱼组、石斑鱼颗粒饲料1组和石斑鱼颗粒饲料2组),每组3个网箱,每箱45尾。养殖实验为期7周,每天定时定点投喂两次。结果表明:冰鲜杂鱼组的增重率、特定生长率、摄食率均显著高于两种颗粒饲料组;群体离散度则是冰鲜杂鱼组大于颗粒饲料组;冰鲜杂鱼组粗蛋白含量显著高于两种颗粒饲料组,但是粗脂肪含量显著低于颗粒饲料组;斜带石斑鱼每增重1 kg所需的饲料成本,饲喂冰鲜杂鱼要比饲喂两种颗粒饲料分别高3.25和4.26元,性价比较低。这些说明:冰鲜杂鱼在促进斜带石斑鱼生长和鱼体蛋白沉积方面虽然优于配合饲料,但在性价比、便捷性以及鱼体规格一致性上,冰鲜杂鱼则不如配合饲料。
Abstract:
A feeding trail was conducted to compare the difference between one kind of frozen trash fish (diet 1) and two artificial compound feeds (diet 2 and diet 3) in growth performance and cost -effectiveness in grouper Epinephelus coioides.Grouper juveniles with an initial body weight of 10.0 g were randomly divided into three groups with triplicate net cages at a stock density of 45 fish per cage.Fish were handfed one of the three diets to apparent satiation at each meal,twice a day across a feeding period of 7 weeks.The fish receiving frozen trash fish had better weight gain rate,specific growth rate and feeding rate as compared with diet 2 and diet 3;the group dispersion of frozen trash fish was greater than that of the two artificial compound feeds.The whole-body crude protein content was significantly higher,but the crude fat content significantly lower in fish fed with frozen trash fish than that of fish fed with the two artificial compound feeds;however,based on the feed cost per 1 kg of body weight gain,the feed cost of frozen trash fish raised by 3.25 yuan and 4.26 yuan respectively vs the two artificial compound feeds.The results showed that feeding frozen trash fish could achieve faster growth rate and body protein deposition in comparison with feeding artificial compound feeds,but the former is inferior to the latter in feed cost-effectiveness,accessibility,and the consistency of fish size.
