Abstract

Skipjacks in the western and southern waters of North Maluku Province were caught using pole and line with FADs. Skipjack usually swims near the surface water and  tends to be classified as a juvenile skipjack that caught during fishing activities. The study objective was to analyze biological data of skipjack including length weight  relationship, growth, length at first maturity/lm and catch size, size composition and gonad maturity. Skipjack samples were caught in the waters of the western (zone A) and southern (zone b) areas of North Maluku Province, from April 2012 until May 2013. The sudy results show the value bof  skipjack caught around FADs  at zone A and B were similar as b=3. This indicates that the growth of skipjack in both areas was categorized as in isometric pattern. L∞  of skipjack caught at zone A  was 75 cm at the age of 56 months and  at zone B was 76 cm at the age of 56 months. Lm value skipjack caught in zone A and zone B was obtained by 43 cm, with a range of long-forked skipjack caught in zone A from 26.0 to 72.0 cm, and at zone B from 26- to 71 cm , The gonad maturity at zone A and  B, was obtained in  the similar stages as  maturity stages I, II, III,IV, and V. TKG V of the skipjack caught around FADs zone A is found in March and B in July, so it can be presumed skipjack in two zones throughout the year with peak spawning occurs in March for zone A and  B in July.Keywords: Biological base, skipjack, fishery management, North Maluku

Abstract

Teluk Kao di Pulau Halmahera telah dioperasikan rawai dasar secara intensif oleh nelayan skala kecil. Target tangkapan adalah jenis ikan demersal yang bernilai ekonomis penting. Penangkapan ikan pada suatu lokasi yang dilakukan secara terus menerus dikhawatirkan dapat berpengaruh terhadap keberlanjutan sumberdaya ikan tersebut. Tujuan penelitian ini adalah untuk menganalisis komposisi jenis ikan, TKG jenis ikan target dominan, dan membandingkan laju pancing rawai dasar berdasarkan jumlah mata pancing. Pengumpulan data menggunakan metode survei. Analisis data meliputi: komposisi jenis, distribusi TKG, laju pancing. Hasil penelitian menunjukkan bahwa hasil tangkapan ikan target terdiri atas 18 spesies dikategorikan ke dalam 4 kelompok. Komposisi jenis ikan: kurisi (53%), kakap (22,2%), lencam (11,1%), tangkapan lain (13,7%). Tangkapan sampingan terdiri atas 7 spesies, yang didominasi jenis hiu dengan komposisi yang bervariasi. Proporsi matang gonad berdasarkan ukuran kelas panjang: kurisi 54% (22-23 cm), kakap 50% (18-23 cm), lencam 100% (20-27 cm). Laju pancing pada jumlah mata pancing 400 buah sebesar 4,40 lebih tinggi jika dibandingkan dengan jumlah mata pancing 300, 500, 600, dan 700 buah.

Abstract

The success of development the coastal fishing port in Tobelo of North Halmahera Regency cannot be separated from the existence of basic, functional and supporting facilities, therefore it is necessary to know the conditions and level of utilization of these facilities. The objectives of the research are; describe the existing condition of main and functional facilities and analyze the level of utilization of the main and functional facilities at the Tobelo coastal fishing port, North Halmahera Regency. The research was conducted at the Tobelo coastal fishing port, North Halmahera Regency, for one month, namely in November 2020. The research method used was a case study. The condition of the existence of basic facilities at PPP Tobelo, namely the length of the pier having a capacity of 80.00 m, an area of the port pool of 100 m2, the depth of the pier waters -5.00. The existing condition of functional facilities is an ice factory consisting of 2 units (each with a capacity of 5 tonnes a day), ABF consisting of 2 units (each with a capacity of 5 tonnes / 24 hours) and cold storage consisting of 2 units (each with a capacity of 50 tonnes). The utilization rate of the length of the pier and port pond exceeds the optimal limit of the installed capacity, then the utilization rate of the depth of the pier waters, ice factory, air blast freezer, and cold storage is not optimal.
