Data of this article describes growth, survival rate, water quality and hemato-biochemical indices of Nile Tilapia () fry. To collect the data, the Nile Tilapia fry was reared in 30 L glass aquarium (18 fish/ tank) for 56-days under controlled environmental condition. Feed was prepared with 25 and 50% replacement of commercial fish meal with sp. and sp microalgae, while no replacement was made for control feed. Initial and final body weight of fish was recorded to find the data of growth rate; survival rate was calculated from the initial and final live individuals recorded during the experiment; physico-chemical parameters were analyzed to collect water quality data; hemato-biochemical indices were collected using hematology analyzer and photometry. The data on growth, survival rate and hemato-biochemical indices were statistically significant (p < 0.05). Therefore, these data might contribute to the selection of marine microalgae to improve the water quality during fish farming which could enhance the growth and survivability of fish. In addition, the data of hemato-biochemical indices represent that feeding selected marine microalgae might result in the production of healthy and disease-free fish.
本文数据描述了尼罗罗非鱼鱼苗的生长、存活率、水质及血液生化指标。为收集数据，将尼罗罗非鱼鱼苗饲养在30升玻璃水族箱（每箱18尾鱼）中，在可控环境条件下饲养56天。饲料制备时，分别用25%和50%的螺旋藻属和小球藻属微藻替代商业鱼粉，对照饲料则不做替代。记录鱼的初始和终末体重以获取生长率数据；根据实验期间记录的初始和终末存活个体计算存活率；分析理化参数以收集水质数据；使用血液分析仪和光度计收集血液生化指标。生长、存活率和血液生化指标的数据具有统计学意义（p < 0.05）。因此，这些数据可能有助于选择海洋微藻以改善养鱼过程中的水质，从而提高鱼的生长和生存能力。此外，血液生化指标数据表明，投喂选定的海洋微藻可能会培育出健康且无病害的鱼。
