摘要：【中文】本发明属于鱼类遗传营养学技术领域，特别是指一种高植物蛋白耐受黄颡鱼仔鱼及其培育方法。该方法利用遗传营养学和生物育种学相结合的原则，经试验得出一套高植物蛋白耐受黄颡鱼苗种培育技术体系。将利用配制出的高植物蛋白诱导饲料投喂孵化出膜后3‑15dph的黄颡鱼仔鱼，给与适当时长的植物蛋白饲料短时刺激（高植物蛋白饲料投喂刺激时长5‑15日之间），即可得到与无刺激组特定生长率无显著差异，非特异性免疫能力以及消化吸收能力高于或者和无刺激组无显著差异的黄颡鱼幼鱼苗种。从饲料成本上，高水平的植物蛋白则可以显著降低饲料成本，节约生产成本，提高养殖效益。 【EN】The invention belongs to the technical field of fish genetic nutrition, and particularly relates to a pelteobagrus fulvidraco fry with high vegetable protein tolerance and a cultivation method thereof. The method utilizes the principle of combining genetic nutriology and biological breeding science, and a set of pelteobagrus fulvidraco fry breeding technical system with high vegetable protein tolerance is obtained through tests. The pelteobagrus fulvidraco juvenile fish which is hatched for 3-15dph after the prepared high vegetable protein induction feed is fed to the pelteobagrus fulvidraco juvenile fish, and is given with the vegetable protein feed for short-time stimulation for a proper time (the high vegetable protein feed is fed for 5-15 days), so that the pelteobagrus fulvidraco juvenile fish fry which has no significant difference from the non-stimulation group in specific growth rate and has higher non-specific immunity and digestion and absorption capacity or no significant difference from the non-stimulation group can be obtained. From the feed cost, the high-level vegetable protein can obviously reduce the feed cost, save the production cost and improve the culture benefit.
