Abstract

The study examined the impacts of varying protein levels and additional substrate area for periphyton formation on the growth and survival of whiteleg shrimp postlarvae reared in a biofloc system. Shrimp postlarvae were stocked in eighteen 100L tanks each filled with 60L of seawater (28 ‰ salinity). In a 3×2 factorial arrangement, the experimental diets were formulated to contain three varying dietary protein levels (25, 35, and 45% CP). Shrimp diets were prepared and supplied

在生物絮团系统中，日粮蛋白质和浮游生物的协同作用可促进万年青的生长、饲料消耗和基因表达。

该研究考察了不同蛋白质水平和用于形成浮游生物的额外底质面积对在生物絮凝物系统中饲养的南美白对虾幼体的生长和存活率的影响。对虾幼体被放养在 18 个 100 升的水槽中，每个水槽装有 60 升海水（盐度为 28‰）。实验日粮采用 3×2 的因子排列，包含三种不同的日粮蛋白质水平（25%、35% 和 45% CP）。对虾日粮的配制和供应

期刊介绍： The main focus of Egyptian Journal of Aquatic Biology and Fisheries is to publish peer-reviewed, original papers relating to the biology and ecology of fresh, brackish and marine wetlands. Papers on applied research in both fisheries and aquaculture are so encouraging. Preference will be given to studies that address timely and current topics such as impact of climate change and green economy. The aim of Egyptian Journal of Aquatic Biology and Fisheries is to provide a wide scope for the aquatic biologist and limnologist to address and evaluate fisheries issues related to processes and functioning at different levels (individuals, communities and ecosystems).
