This study evaluates the effect of different diets supplemented with vitamin solutions on catfish broodstock reproduction, growth performances, and the survival rates of fish larvae and fingerling. The growth and reproductive performances of breeders fed with different test diets showed significant differences among the six tested diets ( < 0.05). The highest final body weight (FBW), weight gain (WG), daily weight gain (DWG), specific growth rate (SGR) of broodstock, and survival rate of fingerlings were found in Treatment 5, which contained 0.6% H-OVN mixed with 12.6% algal oil, and Treatment 3, which contained 0.6% vitamin premix H-OVN. The average gonadosomatic index (GSI), relative fecundity index (RFI), fertilized eggs, hatching rates of eggs, and survival rate of fingerlings was 9.1 ± 2.8 (6.7-12.8%), 133,224 ± 39,090 (104,267-199,512 eggs/kg), 77.9 ± 22.2 (62.2-93.6%), and 45.3 ± 17.4 (22.0-66.3%), respectively. The findings of this study showed that the diet containing 35% CP contents supplemented with 0.6% vitamin premix H-OVN mixed with algal oils showed the highest results in terms of growth, reproductive performance indices, and survival rates of catfish fingerlings.
本研究评估了添加维生素溶液的不同日粮对鲶鱼亲鱼繁殖、生长性能以及鱼苗和鱼种存活率的影响。饲喂不同试验日粮的亲鱼的生长和繁殖性能在六种试验日粮之间存在显著差异（<0.05）。在含有0.6% H-OVN与12.6%藻油混合的处理5和含有0.6%维生素预混料H-OVN的处理3中，亲鱼的最终体重（FBW）、体重增加（WG）、日增重（DWG）、特定生长率（SGR）以及鱼种存活率最高。平均性腺指数（GSI）、相对繁殖力指数（RFI）、受精卵、鱼卵孵化率和鱼种存活率分别为9.1±2.8（6.7-12.8%）、133,224±39,090（104,267-199,512枚卵/千克）、77.9±22.2（62.2-93.6%）和45.3±17.4（22.0-66.3%）。本研究结果表明，含有35%粗蛋白含量并添加0.6%维生素预混料H-OVN与藻油混合的日粮在鲶鱼鱼种的生长、繁殖性能指标和存活率方面表现出最高的结果。
