There was a unique brackish water ecosystem and affected a chance in the plankton composition at lagoon and riverside in Segara Anakan Cilacap. This study aimed to map phytoplankton and zooplankton composition consisting of freshwater and marine plankton from the lagoon to the marine entrance in the west part of Segara Anakan Cilacap. The survey method was taken with purposive random sampling in fourteen stations and four replicates with new and full moon conditions from March to April 2018 in a wet season. The result showed 52 species of plankton. All species belonged to phylum Cyanophyta (9 species), Chlorophyta (13 species), Chrysophyta (19 species), Euglenozoa (2 species), Rotifera (2 species) and Arthropoda (7 species). Of the 52 species collected in all stations and replicates, phytoplankton has a greater species richness (41 species) than zooplankton (11 species). And also, freshwater plankton (47 species) has a higher species richness than marine plankton (5 species) due to the wet season condition causing freshwater enters brackish water. The largest freshwater of River Citanduy enters the brackish water of Segara Anakan mangrove ecosystem in Cilacap and causing the freshwater phytoplankton abundance, especially Staurastrum sp. in inland waters of Segara Anakan Cilacap.

西拉卡普塞加拉阿纳坎红树林生态系统西部从泻湖到海洋入口的浮游生物组成
Segara Anakan Cilacap 有一个独特的咸水生态系统,影响了泻湖和河边的浮游生物组成。本研究旨在绘制由泻湖到 Segara Anakan Cilacap 西部海洋入口的淡水和海洋浮游生物组成的浮游植物和浮游动物组成图。该调查方法是在 2018 年 3 月至 2018 年 4 月雨季的新月和满月条件下,在 14 个站点进行有目的的随机抽样,并进行了 4 次重复。结果显示有52种浮游生物。所有物种均属于蓝藻门(9种)、绿藻门(13种)、金藻门(19种)、裸藻门(2种)、轮虫门(2种)和节肢动物门(7种)。在所有站点和重复中收集的 52 个物种中,浮游植物的物种丰富度(41 种)高于浮游动物(11 种)。此外,由于潮湿的季节条件导致淡水进入咸水,淡水浮游生物(47种)的物种丰富度高于海洋浮游生物(5种)。Citanduy 河最大的淡水进入 Cilacap 的 Segara Anakan 红树林生态系统的咸水,导致淡水浮游植物丰富,特别是Staurastrum sp。在 Segara Anakan Cilacap 的内陆水域。
