This study was conducted to examine effects of supplementing nano-selenium in a plant protein-based diet on reproductive performance of female Acanthopagrus arabicus. Two basal diets were formulated including a fishmeal (FM)-based diet and a plant protein (PP)-rich diet. FM-based diet served as a positive control (control) and the PP-rich diet was used as the basal diet for supplementing with 0, 0.5, 1, 2 and 4 mg N-Se Kg⁻¹. Six groups of fish were fed one of the test diets over three months to spawning. Relative fecundity was higher in females fed 4 mg Kg⁻¹ N-Se diet (p < .05). The greatest fertilization rate (FR) was found in broodfish fed 4 mg N-Se Kg⁻¹ diet, but it was not significantly different from the FR in groups fed the control and 2 mg N-Se Kg⁻¹ diets. Eggs from the females fed the control or 2 mg N-Se Kg⁻¹ diets displayed higher hatchability (p < .05). The highest length and survival rate at 3-days post-hatch were observed in larvae of females fed 2 mg N-Se Kg⁻¹ diet (p < .05). The results indicated that administration of 2–4 mg N-Se Kg⁻¹ in PP-rich diets has beneficial effects on reproduction of female A. arabicus.

植物蛋白日粮中添加纳米硒对雌性阿拉伯黄鳍鲷（Acanthopagrus arabicus）繁殖性能及卵子和幼体质量的影响

本研究旨在检验在以植物蛋白为基础的饮食中补充纳米硒对雌性阿拉伯棘刺鱼繁殖性能的影响。制定了两种基础日粮，包括基于鱼粉 (FM) 的日粮和富含植物蛋白 (PP) 的日粮。基于FM的饮食用作阳性对照（对照），富含PP的饮食用作补充0、0.5、1、2和4mg N-Se Kg ^-1的基础饮食。六组鱼在三个月内喂食其中一种测试饲料直至产卵。^{饲喂 4 mg Kg -1}  N-Se 饮食的雌性相对繁殖力较高（p < .05）。^{在喂食 4 mg N-Se Kg -1}的亲鱼中发现最大的受精率 (FR)饮食，但在喂食对照组和 2 mg N-Se Kg ^-1饮食的组中，它与 FR 没有显着差异。喂食对照或 2 mg N-Se Kg ^-1日粮的雌性鸡蛋显示出更高的孵化率（p < .05）。^{在喂食 2 mg N-Se Kg -1}日粮的雌性幼虫中观察到孵化后 3 天的最高长度和存活率（p < .05）。结果表明，在富含 PP 的饮食中施用 2-4 mg N-Se Kg ^-1对雌性A的繁殖有益。 阿拉比克_
