水产动物苗种是水产养殖业的重要一环，人工育苗在传统上主要依赖于单胞藻、轮虫及卤虫无节幼体等活饵（也使用少量豆浆、蛋黄等代用饲料）作为开口饵料。然而活饵产量受到自然资源、天气状况和培养技术等因素的制约，且占用养殖水面，还有引入病原生物的可能。故水产界一直在 Aquaculture animal husbandry is an important part of aquaculture. Artificial breeding has traditionally relied mainly on live bait (also using small amounts of soy milk, egg yolks and other alternative feeds) as monocytogenes, rotifers and Artemia nauplii as the open bait .

Therefore, the aquaculture community has been
