摘要

本研究旨在探讨添加蛋氨酸对黑线鲈生长性能、饲料利用率、生化指标和经济评估的影响。总共 180 尾鱼苗经过驯化后被随机分配到实验水族箱中。鱼被分配到 12 个水族箱中，每个水族箱中有 15 尾鱼苗，每尾鱼苗的初始平均体重为 83.50±0.485 克。在标有 D1、D2、D3 和 D4 的实验日粮中分别添加 0、5、10 和 15 克/千克的蛋氨酸，持续 56 天。生长性能指标，如总增重（TBWG）、日增重（ADG）和特定生长率（TBW）。

Productive Performance, Feed Utilization, Biochemical Parameters, and Economic Evaluation of the Nile Tilapia (Oreochromis niloticus) Fed Diets Containing Different Levels of Methionine

This study aimed to explore the impact of adding methionine on growth performance, feed utilization, biochemical parameters, and economic assessment of Oreochromis niloticus . A total of 180 fries were acclimated and then randomly allocated into the experimental aquariums. Fish were distributed across 12 aquaria with 15 fry each, having an initial average weight of 83.50± 0.485g per aquarium. Methionine was incorporated at levels of 0, 5, 10, and 15g/ kg in experimental diets labeled D1, D2, D3, and D4, respectively for 56 days. Growth performance metrics such as total body weight gain (TBWG), daily gain (ADG) and specific growth rate (

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).
