Cilacap has a high potential for marine fisheries. However, no scientific data is available on the potential of marine ornamental fish from that area. Here we reported the preliminary study of the potential of marine ornamental fish from the southern coast of Cilacap with particular emphasis on species richness. A survey method with incidental sampling was conducted. Fish samples bought from the fish collector in Sentolo Kawat Village, District of South Cilacap, at Cilacap City. The fish samples were collected in April, May, and July 2019. Taxonomic identification of the fish samples was referring to the available reference and validated to the data in FishBase. Identification based on color pattern and meristic characters by considering geographic ranges of the specimen placed the samples into 28 species, 12 families, and four orders. Chaetodontidae was the most abundant family with nine species. Most fish belonged to Perciformes. We obtained a lower number of species compared to the previous study for the south coast of Java. It could be due to the narrower sampling areas and limited sampling periods. Nevertheless, our result provides information about the potential of marine ornamental fish in Cilacap as among promising income sources for the Cilacap Regency. However, government intervention is necessary for the sustainable use of ornamental fish in the area.

Cilacap 在海洋渔业方面具有很高的潜力。然而，没有关于该地区海洋观赏鱼潜力的科学数据。在这里，我们报告了对 Cilacap 南部海岸海洋观赏鱼潜力的初步研究，特别强调了物种丰富度。进行了附带抽样的调查方法。从位于 Cilacap 市 South Cilacap 区 Sentolo Kawat 村的鱼类采集者处购买的鱼类样本。鱼类样本于 2019 年 4 月、5 月和 7 月采集。鱼类样本的分类学鉴定参考了现有的参考资料，并根据 FishBase 中的数据进行了验证。通过考虑标本的地理范围，基于颜色图案和分生特征进行鉴定，将样品分为 28 个种、12 个科和 4 个目。Chaetodontidae 是最丰富的科，有九种。大多数鱼属于鲈形目。与之前对爪哇南海岸的研究相比，我们获得的物种数量较少。这可能是由于更窄的采样区域和有限的采样周期。尽管如此，我们的结果提供了有关 Cilacap 海洋观赏鱼作为 Cilacap 摄政区有希望的收入来源的潜力的信息。然而，政府干预对于该地区观赏鱼的可持续利用是必要的。我们的结果提供了有关 Cilacap 的海洋观赏鱼作为 Cilacap Regency 有希望的收入来源的潜力的信息。然而，政府干预对于该地区观赏鱼的可持续利用是必要的。我们的结果提供了有关 Cilacap 的海洋观赏鱼作为 Cilacap Regency 有希望的收入来源的潜力的信息。然而，政府干预对于该地区观赏鱼的可持续利用是必要的。
