摘要
“配合饲料”以植物蛋白质和碳水化合物为主，加以适量各种添加剂，经科学调配混合组成。蛋白质含量２５－２６％，脂肪８４－１２９％，碳水化合物４３－５６％，并含有扇贝亲贝性腺成熟必需的微量元素和其他促进性腺成长发育的重要成分。经饲喂试验表明：亲贝性腺指数提高２０－３０％，亲贝成活率９８％，比对照提高２６％，亲贝产出优质精、卵，受精卵的孵化率９３％，饲料成本降低５０％，是一种完全可以代替单胞藻喂养扇贝亲贝的优良配合饲料。
Composed of protein (25-26%),Carbohydrate (43-56%),Fat (8.4-12.9),small amount of trace elements which is necessary for maturation of gonad,the diet has been demonstrated to be an ideal food for conditioning parent scallops.It can not only promote the development of gonad,but activate the synthesis of protein in the body of scallops.Fed with the diet,the survival rate and gonad index of parent scallops reached to 98% and 24%,28% and 20-30% higher than those fed with unicellular algae respectively.Comparing with those completely feeding unicellular algae,the cost of hatchery was reduced to 50%.With the advantage of easy for preparation,low cost ,high fertilizing rate (93%) and rich in natural resources,it is an ideal diet for replacing phytoplankton as the food for parent scallops.
