Malnutrition has emerged as a noticeable obstruction to the socio-economic advancement of rural areas along the coastal regions of Bangladesh. Small indigenous fish species (SIS) have the potential to alleviate the malnutrition issue because of having higher nutritional compositions. However, prior research has overlooked the detailed nutritional value of SIS originating from coastal regions. Consequently, the current investigation sought to analyze the mineral and fatty acid composition of twelve SIS obtained from coastal homestead ponds. The findings indicated that the mineral composition in SIS exhibited the following descending order: calcium (Ca) > phosphorus (P) > potassium (K) > magnesium (Mg) > iron (Fe) > zinc (Zn). Furthermore, when considering the overall mineral content in SIS, it ranked in the following decreasing order: , , , , , , , , , , , and . The analysis of the fatty acid profile further revealed that SIS is a rich source of palmitic acid, linoleic acid, oleic acid, stearic acid, myristic acid, palmitoleic acid, and linolenic acid. The saturated fatty acid content of the SIS varied between 42.66 % and 63.37 %, and the highest content was found in whereas the lowest was in . On the other hand, the total monounsaturated fatty acid content of the SIS ranged from 26.49 % () to 46.12 % (), and the total PUFAs contents among the fish species ranged from 5.7 % (A. mola) to 16.54 % (). Therefore, SIS could be a key source of minerals and essential fatty acids for human well-being. This can help fulfill nutrient requirements and reduce malnutrition among coastal populations. It can be said that, if these fishes are introduced in the culture systems, it will be used for consumption as well as support the livelihood of coastal people.
营养不良已成为孟加拉国沿海地区农村社会经济发展的一个显著障碍。小型本土鱼类（SIS）因其具有较高的营养成分，有潜力缓解营养不良问题。然而，先前的研究忽略了源自沿海地区的小型本土鱼类的详细营养价值。因此，当前的调查旨在分析从沿海宅基地池塘获取的12种小型本土鱼类的矿物质和脂肪酸组成。研究结果表明，小型本土鱼类中的矿物质组成呈现以下降序排列：钙（Ca）>磷（P）>钾（K）>镁（Mg）>铁（Fe）>锌（Zn）。此外，就小型本土鱼类中的总体矿物质含量而言，其排列顺序如下递减：……（此处原文缺失具体内容）。脂肪酸谱分析进一步表明，小型本土鱼类富含棕榈酸、亚油酸、油酸、硬脂酸、肉豆蔻酸、棕榈油酸和亚麻酸。小型本土鱼类的饱和脂肪酸含量在42.66%至63.37%之间变化，其中……（此处原文缺失具体内容）含量最高，而……（此处原文缺失具体内容）含量最低。另一方面，小型本土鱼类的总单不饱和脂肪酸含量在26.49%（……，此处原文缺失具体内容）至46.12%（……，此处原文缺失具体内容）之间，鱼类物种中的多不饱和脂肪酸总含量在5.7%（A. mola）至16.54%（……，此处原文缺失具体内容）之间。因此，小型本土鱼类可能是人类健康所需矿物质和必需脂肪酸的关键来源。这有助于满足营养需求并减少沿海人口的营养不良状况。可以说，如果将这些鱼类引入养殖系统，它们将可供食用，并支持沿海居民的生计。
