The present dataset provides information on the abundance of microplastics (MPs) in relation to different feeding habits of the four mangrove brachyuran crab species namely and at Setiu Wetlands in Peninsular Malaysia. Three sites namely, Pulau Layat (upstream, close to the core mangrove zone), Kampung Pengkalan Gelap (midstream, close to the settlements), and Pulau Sutung (downstream, close to the shifted river mouth) were chosen for the sample collection (through hand catch method and traps) in both the dry (Feb-Mar 2021) and the wet (Dec 2021 - Jan 2022) seasons. The cardiac stomach of each crab was dissected, digested in potassium hydroxide and then filtered through a 1.6 µm pore size glass fibre filter using the vacuum pump. The abundance, type and colour of MPs per crab individual were determined under a stereomicroscope (Carl Zeiss Stemi 508, China) attached to the digital camera (Axiocam 208 colour). The general abundance of MPs was found in the order of carnivorous > microphytobenthos feeder > herbivorous > detritivorous . The data also reveal morphometric measurements such as body weight, gut weight, carapace width and carapace length of the crab specimens. The information given in this article is useful for study replications and scientific comparisons, especially with brachyuran crabs and other organisms with similar feeding guilds, in the mangroves of Malaysia and elsewhere.
本数据集提供了马来西亚半岛Setiu湿地四种红树林短尾蟹（即 和 ）不同摄食习性下微塑料（MPs）丰度的信息。选择了三个地点进行样本采集（通过手工捕捉和陷阱法），分别是Pulau Layat（上游，靠近红树林核心区）、Kampung Pengkalan Gelap（中游，靠近定居点）和Pulau Sutung（下游，靠近改道的河口），采集时间为旱季（2021年2月 - 3月）和雨季（2021年12月 - 2022年1月）。对每只螃蟹的贲门胃进行解剖，在氢氧化钾中消化，然后使用真空泵通过孔径为1.6 µm的玻璃纤维滤膜过滤。在连接数码相机（Axiocam 208彩色）的体视显微镜（卡尔蔡司Stemi 508，中国）下确定每只螃蟹个体的微塑料丰度、类型和颜色。发现微塑料的总体丰度顺序为肉食性 > 微型底栖藻类摄食者 > 草食性 > 碎屑食性。数据还显示了螃蟹标本的形态测量数据，如体重、肠道重量、头胸甲宽度和头胸甲长度。本文提供的信息对于研究复制和科学比较很有用，特别是对于马来西亚和其他地方红树林中的短尾蟹及其他具有相似食性类群的生物。
