The rapid development of aquaculture has led to an increase in price and high demand for fishmeal. Finding candidate protein sources for replacing fishmeal has become an urgent matter for the healthy and sustainable development of Ajaponicus aquaculture. Therefore, we evaluated the effect of fishmeal subjected to enzymolysis (EF) and scallop mantle subjected to enzymolysis (ESM) by papain as a substitute for fishmeal on the growth, antioxidant activity and non-specific immune response of Ajaponicus. The results showed that EF and ESM did not lead to a difference in the growth performance of Ajaponicus. However, the activity of respiratory burst and phagocytic increased in ESM group. The expression of Lysozyme (LZM) increased in the intestine of the EF and ESM group, while the expression level of superoxide dismutase (SOD) was reduced in the intestine and respiratory tree of the EF and ESM group. In conclusion, EF and ESM have no effect on the growth performance but could modulate the non-specific immune responses of juvenile sea cucumber. Therefore, scallop mantle subjected to enzymolysis by papain is a candidate protein source for replacing fishmeal in the aquaculture of Ajaponicus.

木瓜蛋白酶酶解鱼粉和扇贝皮作为鱼粉的替代品可以调节幼海参(Apostichopus japonicus)的生长、抗氧化活性和非特异性免疫反应

水产养殖业的快速发展导致鱼粉价格上涨和需求旺盛。寻找替代鱼粉的候选蛋白质来源已成为A刺参养殖业。因此,我们评估进行酶解(EF)鱼粉和扇贝地幔进行酶解(ESM)通过木瓜蛋白酶作为上生长,抗氧化活性和非特异性免疫应答鱼粉的替代的效果。 粳稻。结果表明,EF 和 ESM 不会导致A的生长性能出现差异。 粳稻. 然而,ESM组呼吸爆发和吞噬活动增加。EF和ESM组溶菌酶(LZM)在肠道中的表达增加,而在EF和ESM组的肠道和呼吸树中超氧化物歧化酶(SOD)的表达水平降低。总之,EF和ESM对海参的生长性能没有影响,但可以调节幼年海参的非特异性免疫反应。因此,通过木瓜蛋白酶进行酶解扇贝地幔是用于在水产养殖代替鱼粉的候选蛋白质源。 粳稻
