Abstract

The division of Indonesian waters into several fisheries management areas illustrates very different habitat characteristics and has a diversity of biological resources that may vary. WPPNRI 716 is a management area in Indonesian waters which includes the waters of the Sulawesi Sea and the northern part of Halmahera Island. This research was carried out by the purse seiner KM. Rebert carried out fishing operations in the waters of the Sulawesi Sea at WPPNRI 716. Data collection was carried out for 4 months, namely from October 2021 - to January 2022, with the aim of knowing the distribution area of catching and KM. Rebert catches. KM. Rebet catchment area based on the GPS point is located at WPPNRI 716, which is 81.5 miles from the fishing base (Tumumpa Beach Fishery Port). The number of catches in October (trip 1) was 6350 kg, in October (trip 2) was 4807 kg, in November (trip 3) was 10245 kg, in December (tip 4), was 4234 kg, in December (trip 5) as much as 4280 Kg, in January (trip 6) as many as 2645, and in January (trip 7) 4350 Kg. Judging from the type of catch during the research, there was 13265 kg of mackerel scad (Decapterus sp), then 12953 kg of skipjack tuna (Katsuwonus pelamis L), 4884 kg of yellowfin tuna (Thunnus albacares), and 4100 kg of mackerel tuna (Euthinnus affinis). Selar fish (Selaroides sp) as much as 904 Kg, jackfish (Caranx sp) as much as 500 Kg, rainbow runner fish (Elagatis bipinnulatus) as much as 350 Kg, and the lowest is bullet tuna (Auxis rochei) fish as much as 55 Kg.Keywords: Mapping; KM.

WPPNRI 716 merupakan wilayah pengelolaan di perairan Indonesia yang meliputi perairan Laut Sulawesi dan sebelah Utara Pulau Halmahera.Penelitian ini dilaksanakan kapal pukat cincin (purse seiner) KM. Rebert yang melakukan operasi penangkapan ikan di perairan Laut Sulawesi pada WPPNRI 716.  Pengambilan data dilakukan selama 4 bulan yaitu pada bulan Oktober 2021 - Januari 2022, dengan tujuan untuk mengetahui daerah sebaran penangkapan dan hasil tangkapan KM. Rebert. Daerah penangkapan KM. Rebet berdasarkan titik GPS berada pada WPPNRI 716 yang berjarak dari fishing base (Pelabuhan Perikanan Pantai Tumumpa) ± 81,5 mil. Jumlah hasil tangkapan pada bulan bulan Oktober (trip 1) sebanyak 6350 Kg, bulan Oktober (trip 2) sebanyak 4807 Kg, bulan November (trip 3) sebanyak 10245 Kg, bulan Desember (tip 4), sebanyak 4234 Kg, bulan Desember (trip 5) sebanyak 4280 Kg, bulan Januari (trip 6) sebanyak 2645, dan bulan Januari (trip 7) 4350 Kg. Dilihat dari jenis tangkapan selama penelitan adalah ikan layang (Decapterus sp) sebanyak 13265 Kg, kemudian ikan cakalang (Katsuonus pelamis L) sebanyak 12953 Kg, ikan tuna sirip kuning (Thunnus albacares) sebanyak 4884 Kg, ikan tongkol (Auxis rochei) sebanyak 4100 Kg ikan selar (Selaroides sp) sebanyak 904 Kg, ikan kuwe (Caranx sp) sebanyak 500 Kg, ikan sunglir (Elagatis bipinnulatus) sebanyak 350 Kg, dan yang paling rendah adalah ikan tongkol (Auxis rochei) sebanyak 55 Kg.Kata Kunci:Pemetaan; KM.

Abstract

AbstractBubu fisheries have developed well in all Indonesian waters, especially in coastal areas that have coral reef and seagrass habitats. Generally, the commodities targeted for fishing are types of reef fish and seagrass beds that have a high selling value, such as snapper, grouper, baronang, yellowtail, lobster, octopus, and others. Bubu fishing gear or traps called bebihe local people are one of the fishing gear used to catch demersal fish or reef fish. The success of the bubu fishing operation is greatly influenced by the construction of the bebihe fishing gear itself and the treatment of the bait used. The use of seagrass bait, allegedly can increase the catching ability of the bebihe. However, scientific information on the use of seagrass as a bait for bebihe for fishing is not yet available. Therefore, the purpose of this study is to determine the effectiveness of seagrass baits with the comparison of kitefish in the operation of bebihe; and identify the types of fish caught.This research was carried out in the waters of Beeng Laut island, South Central Tabukan District, Sangihe Islands Regency; is based on experimental methods. Six bebihe units were operated during nine trips to collect data; where three units use seagrass bait of the type Thalassia hemprichii, and the other three units use kite fish bait; and then the catch data is analyzed by a t-test.The catch of bebihe during the study amounted to 363 heads, as many as 345 were caught with seagrass baits, and 18 were caught with kite baits. Analysis of the t-test showed that at t count = 5.480 > t table 0.05;8 = 2.306; where this explains that the use of seagrass bait on bebihe, gives a noticeablely different catch compared to kitefish bait.

Abstract

Skipjack tuna is classified as an important pelagic fishery resource and is one of the export commodities so that production needs to be continuously increased by maintaining the sustainability of these fish resources. This study aims to determine the development of production and productivity of the pole and liner vessels observed and to determine the length-weight relationship of the catches of the pole and liner vessels observed at the Bitung Ocean Fishing Port (PPS). In general, the production and productivity of pole and liners based at the Samudera Bitung Fishing Port increased from November 2021 to December 2021 and then decreased again in January 2022, so that they were declared unproductive. Pole and liner catches that are landed at the Bitung Ocean Fishing Port in the period November 2021 - January 2022 tend to get the same results with the size caught, namely 29-64 cm, with a positive allometric growth pattern. Keywords : Production and Productivity, Growth Patterns, Pole and Liner Abstrak Ikan cakalang tergolong sumberdaya perikanan pelagis penting dan merupakan salah satu komoditi ekspor sehingga produksinya perlu terus ditingkatkan dengan menjaga kelestarian sumberdaya ikan tersebut. Penelitian ini bertujuan untuk mengetahui perkembangan produksi dan produktivitas dari kapal pole and liner yang diamati dan mengetahui hubungan panjang-berat hasil tangkapan kapal pole and liner yang diamati di Pelabuhan Perikanan Samudera (PPS) Bitung. Secara umum produksi dan produktivitas pole and liner yang berpangkalan di Pelabuhan Perikanan Samudera Bitung mengalami kenaikan dari bulan November 2021 ke bulan Desember 2021 dan selanjutnya mengalami penurunan kembali pada bulan Januari 2022, sehingga dinyatakan tidak produktif. Hasil tangkapan pole and liner yang didaratakan di Pelabuhan Perikanan Samudera Bitung pada periode November 2021 – Januari 2022 cenderung mendapatkan hasil yang sama dengan ukuran yang tertangkap yaitu 29-64 cm, dengan pola pertumbuhan bersifat alometrik positif.
