Abstract

Perairan Dompak, Kota Tanjungpinang, Provinsi Kepulauan Riau merupakan salah satu area penangkapan krustasea, salah satunya adalah kepiting merah (Thalamita spinimana). Belum adanya penelitian terkait aspek makanan dan kebiasaan makan kepiting merah (T. spinimana) di Perairan Dompak menjadikan penelitian terkait aspek tersebut penting untuk dilakukan. Tujuan penelitian ini adalah untuk mengetahui komposisi makanan kepiting merah (T. spinimana) khususnya Perairan Dompak Kota Tanjungpinang Kepulauan Riau. Penelitian ini menggunakan metode survei. Pengambilan sampel kepiting merah (T. spinimana) dilakukan selama 2 bulan sebanyak 4 kali. Analisis data untuk mengetahui kebiasaan makanan kepiting merah (T. spinimana) menggunakan index of preponderance (IP). Hasil penelitian diketahui bahwa jumlah kepiting merah yang diperoleh sebanyak 34 ekor, terdiri dari 21 ekor kepiting merah betina dan 13 ekor kepiting merah jantan. Kelompok makanan kepiting merah (T. spinimana) terdiri dari mikroalga, krustasea, dan detritus. Hasil indeks bagian terbesar / IP diketahui bahwa makanan utama kepiting merah di Perairan Dompak adalah kerang, sedangkan makanan pelengkap adalah detritus dan fitoplankton, makanan tambahan yaitu zooplankton. Nilai indeks kepenuhan lambung kepiting merah (T. spinimana) pada waktu malam hari (1,11), pagi hari (0,96) dan siang hari (0,63). Kepiting merah (T. spinimana) di Perairan Dompak dominan melakukan aktivitas makan pada malam hari. Dompak Waters, Tanjungpinang City, Riau Islands Province is one of the areas for catching crustaceans, one of which is the red swimming crab (Thalamita spinimana). The absence of research related to food and feeding habit aspects of red swimming crab in Dompak Waters makes research related to these aspects important to do. The purpose of this study was to determine the food composition of red swimming crab, especially Dompak waters, Tanjungpinang City, Riau Islands. This study used a survey method. Sampling of red swimming crab was carried out for 2 months with 4 sampling times. Data analysis to determine the food habit of red swimming crab using the index of preponderance (IP). The results showed that the number of crabs obtained was 34, consisting of 21 female red swimming crab and 13 male red swimming crab. The red swimming crab food group consists of microalgae, crustaceans, and detritus. The results of the largest share / IP index show that the main food of red swimming crab in Dompak Waters is bivalvia, while the complementary food are detritus and phytoplankton, the additional food is zooplankton. The index value of stomach fullness of red swimming crab at night (1.11), morning (0.96) and afternoon (0.63). This result is known that the red swimming crab in Dompak waters eats predominantly at night.
Thalamita spinimana(Dana 1852)在绵羊水中,丹绒皮南,River Island
廖内河省坦永平市的doaroang水是甲壳类动物的领地之一,其中之一是红螃蟹(Thalamita spinkota)。尚未对公海上红蟹的饮食和饮食习惯进行研究,这使得相关研究变得至关重要。这项研究的目的是确定红蟹的食物成分(T. spin如何),特别是廖内腾堡市的公海。这项研究采用了一种调查方法。红蟹的样本采集进行了2个月4次。分析数据,发现红蟹的食物习惯使用了preponderance索引。研究发现,多达34只红螃蟹的数量由21只雌性红螃蟹和13只雄性红螃蟹组成。红蟹的食物包括微藻、甲壳类动物和碎屑。最大的部分/ IP索引显示,红蟹在公海上的主要食物是贝类,而补充食物是碎屑和浮游植物,这是一种叫做浮游动物的补充食物。红蟹在夜间(1.11)、早晨(0.96)和白天(0.63)的总量。红蟹在主食水域主要从事夜间进食活动。廖内省坦荣格市、廖内群岛的省份是捕获甲壳类动物的地区之一,也是赤潮蟹的领地。缺乏对食物和食物喂养的红游泳螃蟹的研究,使研究对这些没用的昆虫很重要。这项研究的目的是确定红游泳螃蟹的食物组合,特别是渡河,廖内翻市市。这个研究使用了调查方法。红游泳蟹的样本被埋了2个月,每次4次。分析数据,用索引分析红游泳螃蟹的食物线索。据推测,螃蟹的报告显示,螃蟹的发病率是34岁,包括21只雌性游泳螃蟹和13只游泳螃蟹。红烧蟹群的食物包括微藻、甲壳类动物和碎屑。《大分享索引》指出,在水域中最主要的红游泳螃蟹是双壳的,而完整的食物是腐烂的,植物浮游生物是额外的食物是浮游动物。晚上1点11分,早上6点和下午3点。这只result被认为是一只红游泳的螃蟹在夜间出没。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
