采用室内池子多层笼养殖方式 ,以加工海带、鲜江艹离 与 A,B2种片状饲料为饵料 ,试验了不同食物与不同放养水层对九孔鲍生长影响 ,结果表明 :( 1)从壳长增长上 ,海带与饲料 B近似 ,各为 11.3与 11.2 mm;其次为饲料 A,10 .2 mm;而江 艹离 最差 ,仅 7.7mm;( 2 )在体重增长上 ,以饲料 B最高 ,平均每只为 3.3g,其次为饲料 A与海带 ,平均每只 2 .9g,而江艹离 仅 1.8g;( 3)从试验期间所获体重增长比壳长增长看 ,两种饲料 ( B为 2 95,A为 2 84 mg/mm)均比两种海藻高 (海带为 2 57,江艹离 为 2 34mg/mm) ;( 4 )从垂直 11层笼子九孔鲍生长的比较 ,下层的好于上层 ,越是下层越好 ,投喂两种饲料在体重上差别更明显。
The method of multi-layer cage culture in indoor ponds was used to test the effects of different foods and different stocking water layers on the growth of nine-hole abalone. The results showed that: (1) From the growth of shell length, the kelp was similar to that of feed B, at 11.3 and 11.2 mm each, followed by feed A at 10.2 mm, whereas the kelp was the worst at 7.7 mm. (2) In terms of weight gain, B the highest, with an average of only 3.3g, followed by feed A and kelp, an average of 2.9g, while the river is only 1.8g; (3) from the test during the weight gain growth than shell length, two Feed (B 2 95, A 2 84 mg / mm) was higher than the two seaweeds (25 kelp and 34 34 mg / mm); (4) Comparison, the lower the better than the upper, the lower the better, feeding two kinds of feed on body weight differences more pronounced.
