Abstract

Jaring arad merupakan jaring penangkap udang sebagai hasil tangkapan utama dan memiliki hasil tangkapan sampingan. Tujuan penelitian ini untuk mengidentifikasi hasil tangkap utama dan hasil tangkap sampingan, mengetahui struktur ukuran tangkapan utama, spesifikasi perahu dan alat tangkap arad, serta menganalisis kelayakan usaha penangkapan. Metode yang digunakan adalah metode survei. Pengambilan sampel menggunakan sistematik sampling. Sampel udang diambil secara proporsional yaitu minimal 10% dari total hasil tangkapan. Hasil tangkap selama penelitian terdiri dari 7 spesies krustase, 3 spesies moluska, dan 10 spesies ikan. Ukuran pertama tertangkap (Lc50%)  udang krosok (M. lysianassa) adalah 9 mm, (Lc50%)  udang putih (P. merguiensis) 11 mm. Perahu arad di Tambak Lorok memiliki ukuran relatif sama yaitu 4-8 GT, kekuatan mesin 20-48 PK. Mesh size kantong 24,5 mm.  Hasil tangkapan jaring arad sebesar Rp 426.000,00  per trip, didapatkan dari keuntungan per kilo penjualan udang dan hasil tangkap sampingan. Sedangkan total biaya produksi sebesar Rp. 209.662,00, sehingga diperoleh untung per trip sebesar Rp. 216.337,00 dengan R/C ratio yaitu 2,03 yang mengartikan jaring arad layak diusahakan Arad net is one of fishing gears to catch shrimp as the target species and bycatch. The purposes of this research were to identify the target species and bycatch, to know structure of target species, specification of  fishing boat and arad net, and to analyze the profit and loss of fishing effort. The method used was survey method. This research used systematic sampling. Shrimp samples were taken propotionally at least 10% of the total catch. The results during this research consisted of 7 species of crustacea, 3 species of molluscs, and 10 species of fishes. The size (Lc50%) of Krosok shrimp (M. lysianassa) is 9 mm and the size (Lc50%) of white shrimp (P. merguiensis) is 11 mm. Arad boat at Tambak Lorok has relatively similar size with another (4 to 8 GT). Power machine ranging from 20 to 48 PK, 24,5 mm mesh size. The profit of total species per trip earned from shrimp and bycatch per kilograms is Rp 426.000,00. Meanwhile, the total cost of production was Rp. 209.662,00. Therefore, benefit per trip obtained Rp. 216.337,00 with R/C ratio 2.03 which means arad net is feasible to operating.

阿拉德网是一个主要的捕虾网,并有一个附带的捕虾网。本研究的目的是确定主要的捕获和额外的捕获结果,确定主要的捕获规模的结构,船的规格和捕获设备,并分析捕获的可行性。使用的方法是测量方法。抽样取样是系统性的。对虾样本的比例是总渔获量的10%。在研究过程中捕获的鱼包括7种甲壳类动物、3种软体动物和10种鱼类。第一个捕虾(Lc50%)的捕虾是9毫米,(Lc50%)的白虾(P. merguiensis)是11毫米。Lorok池塘里的arad船的大小是4-8 - GT,发动机功率20-48 . Mesh大小24.5毫米。阿拉德的渔网一次能捕到426.000.00卢比,以每公斤捕虾的利润和利润为由。而生产总成本为209662.00卢比,每旅行收益为216337.00卢比,而R/C ratio值为2.03,这意味着阿拉伯网络是值得追求的目标——物种和副渔抓工具之一。这项研究的目的是确定目标物种和对抓,了解目标物种、渔船和阿拉德网络的结构,并分析渔业努力的利润和损失。使用的方法是调查方法。这个研究使用系统样本。小虾的样本至少占捕虾总量的10%。本研究的结果包括7种甲壳类动物、3种蜕皮动物和10种鱼类。克鲁帕虾的尺寸是9毫米,白虾的尺寸是11毫米。Lorok渔场的阿拉德船与另一艘(4至8 GT)的类似大小。24。5毫米mesh尺寸。每公里收获虾和副渔获物的总物种的利润为426.000.00卢比。与此同时,生产的总成本是209662.00卢比。因此,她的名字是p。
