Plant‐based additives are currently used in aquaculture for their various beneficial properties. Curcumin and turmeric are usually applied for their interesting results on growth performance of fish. In this paper, the effect of dietary inclusion of curcumin and turmeric powder on growth performance in fish was studied. Twenty data sets from 5 studies and 29 data sets from 8 publications were respectively computed for curcumin and turmeric in this analysis. Specific growth rate (SGR) was the quantitative criteria recorded for each data set. After, a brief systemic summary of each study, the quantitative analysis was performed. Results showed a significant increase in pooled standard mean difference (SMD) for both fixed and random model in curcumin and turmeric. Although fish species were categorized into family (subcategory), high heterogeneity (>96%) was found in all random and fixed model analysis. Contrary to turmeric, higher curcumin inclusion results in lower specific growth rate. The higher effect sizes observed when fed curcumin at lower inclusion levels suggests that feeding low levels of phytochemicals might be beneficial and its content in turmeric should be analysed for quite homogeneous feed. This study contributes to the analysis of overall growth performance properties of turmeric and curcumin incorporation in fish diet, irrespective to their strong antioxidant and anti‐inflammatory activities.

姜黄和姜黄素对鱼类生长性能的膳食补充效应的荟萃分析

基于植物的添加剂目前因其各种有益特性而在水产养殖中使用。姜黄素和姜黄通常因其对鱼类生长性能的有趣作用而被应用。本文研究了日粮中添加姜黄素和姜黄粉对鱼类生长性能的影响。在此分析中，分别计算了姜黄素和姜黄的5项研究的20个数据集和8个出版物的29个数据集。比增长率（SGR）是每个数据集记录的定量标准。之后，对每个研究进行简要的系统总结，然后进行定量分析。结果显示，姜黄素和姜黄的固定模型和随机模型的合并标准平均差（SMD）均显着增加。尽管鱼种被归类为科（子类），在所有随机和固定模型分析中均发现高度异质性（> 96％）。与姜黄相反，姜黄素含量较高会导致比生长速率降低。当以较低的夹杂物含量饲喂姜黄素时，观察到的效应较大，这表明饲喂低含量的植物化学物质可能是有益的，并且应分析姜黄中姜黄素的含量以获得相当均匀的饲料。这项研究有助于分析姜黄素和姜黄素掺入鱼饲料中的总体生长性能，而不论它们具有强的抗氧化和抗炎活性。当以较低的夹杂物含量饲喂姜黄素时，观察到的效应较大，这表明饲喂低含量的植物化学物质可能是有益的，并且应分析姜黄中姜黄素的含量以获得相当均匀的饲料。这项研究有助于分析姜黄素和姜黄素掺入鱼饲料中的总体生长性能，而不论它们具有强的抗氧化和抗炎活性。当以较低的夹杂物含量饲喂姜黄素时，观察到的效应较大，这表明饲喂低含量的植物化学物质可能是有益的，并且应分析姜黄中姜黄素的含量以获得相当均匀的饲料。这项研究有助于分析姜黄素和姜黄素掺入鱼饲料中的总体生长性能，而不论它们具有强的抗氧化和抗炎活性。
