摘要

为了降低饲料的消耗,采用了一系列试验来确定常见水草(lemana, AWL)、水葫芦(aquatic hyacinth, AWW)和杜鹃花(Azolla, AWA)作为替代饲料来源的营养价值。以这些水草为主要原料,制作了3种等氮(粗蛋白质-30%)等热量饲料。幼鱼三批,每批三十(30)条(平均重5.1克;L- 5.6 cm),分别饲喂AWL、AWW和AWA 3种不同类型的制备饲料。AWL、AWW和AWA饲鱼的增重、PER(蛋白质效率比)和GSI(性腺体细胞指数)显著高于NOR。锥子含有适宜的氨基酸和脂肪,提高了果肉的产量和品质。通过食品供应试验与对照处理的比较,得出了较好的ω-3/ ω-6比值。

Aquatic Weeds as an Encouraging Resource of Alternative Feed for the Tilapia Oreochromis mossambicus
A series of experiments were carried out to ascertain the nutritional value of commonly available aquatic weed i.e., Lemna (AWL), aquatic hyacinth (AWW) and Azolla (AWA) as alternative feed sources for decreasing the expenditure of feed. Using those aquatic weeds as principal ingredient three (3) isonitrogenous (crude protein-30%) and isocaloric feeds were made. Three batches of juvenile fish of thirty (30) numbers per batch (Average weight-5.1 gm; L- 5.6 cm) were provided with 3different types of prepared feeds with AWL, AWW and AWA. Weight gain, PER (Protein Efficiency Ratio) and GSI (Gonado Somatic Index) are significantly high in the AWL, AWW and AWA fed fish than the NOR. The AWL has suitable amino acid and fat that enhances yield and quality of flesh. The better ω-3/ ω-6ratio is obtained from food supplied experiment trial comparison to control treatment.
