几种植物浆养殖卤虫的饵料效果

以各种植物浆为饵料培养卤虫,培养效果差异显著,陆生植物优于水生植物.其中以黄豆叶浆养殖的卤虫成活和生长最佳,第16天时平均存活率(69.6%)和体长(6.436±0.956mm)与螺旋藻粉组相似(分别为66.0%、6.461±1.181mm)而优于酵母组(分别为29.8%、5.216±1.030mm).以黄豆叶浆养殖的卤虫的粗蛋白及氨基酸含量略低于酵母和螺旋藻粉喂养的卤虫,在高密度卤虫养殖中可替代部分螺旋藻粉,降低卤虫养殖的饵料成本.

The effect of some plant pulps for cultivating Artemia

The deals with possibilities of several plant pulps as diets of the brine shrimp Artemia in high density cultivating mode. The results indicate that different pulp has different diet effect on Artemia. In general, the diet effect of terrestrial plant pulp is better than that of aquatic plant pulp. The leaf of soybean is the best of terrestrial plants. Fed with the pulp of soybean leaf , the Artemia get high survival rate ( 69. 6 % ) and large body length (6. 436 .. 0. 956mm) on the 16th cult ivating day, which are similar to that of Artemia fed with powder of Spirulina ( 66. 0% and 6. 641 .. 1. 181mm respectively) and better than that of Artemia fed w ith yeast ( 29. 8% and 5. 216 .. 1. 030mm respectively) . The amount of crude protein and amino acid in Artemia fed w ith soybean leaf is slightly less than that in Artemia fed with powder of Spirulina and yeast respectively . In high density Artemia culture, it is feasible that soybean leaf can partly substitute for powder of Spirulina and yeast.
