Fish is a major part of the Bangladeshi diet, but data on the nutrient composition of marine fish species are sparse. Mesopelagic fish may be a new potential resource of food and nutrients; however, nutrient composition data are lacking. The aim of this study was to provide nutrient composition data of fish species sampled off the coast of Bangladesh and determine their potential contribution to recommended nutrient intakes (RNI). Seven species from the pelagic, mesopelagic, and demersal zones were sampled from the coast of Bangladesh with Dr. Fridtjof Nansen in 2018. Three pooled samples containing 15-840 individuals from each species were analysed at the Institute of Marine Research, Norway. The demersal species contained substantially lower concentrations of nearly all nutrients, whereas the mesopelagic species generally were more nutrient dense. All species, except for the demersal species Bombay duck (9% dry matter), were found to contribute ≥100% to the RNI of vitamin B₁₂, eicosapentaenoic acid, docosahexaenoic acid, and selenium. All species, except for the demersal fish species, contributed ≥25% to the RNI of six or more nutrients. The data presented in this paper are an important contribution to the Bangladeshi food composition table and contribute to the understanding of fish as an important source of micronutrients.

孟加拉国沿海采样的海底，中上层和中层鱼类种类的营养成分及其对粮食和营养安全的潜在贡献-EAF-Nansen计划。

鱼是孟加拉国饮食的主要组成部分，但是有关海洋鱼类物种营养成分的数据很少。中生鱼类可能是一种新的潜在食物和营养来源。但是，缺乏营养成分数据。这项研究的目的是提供孟加拉国沿海采样的鱼类的营养成分数据，并确定其对推荐营养摄入量（RNI）的潜在贡献。2018年，Fridtjof Nansen博士从孟加拉国沿海抽取了中上层，中层和海底带的7种物种。在挪威海洋研究所对3种汇集的样本进行了分析，每个样本包含15-840个人。水下物种所含的几乎所有营养素浓度都大大降低，而中古生种通常营养密度更高。除沉没物种孟买鸭（9％干物质）外，所有物种均对维生素B的RNI贡献≥100％₁₂是二十碳五烯酸，二十二碳六烯酸和硒。除水下鱼类以外，所有其他物种对六种或更多营养素的RNI贡献≥25％。本文提供的数据对孟加拉国食物组成表做出了重要贡献，并有助于将鱼类理解为微量元素的重要来源。
