Saat ini, pengaruh kegiatan pesisir dan pola penangkapan telah mengakibatkan terjadinya dinamika penangkapan ikan yang mempengaruhi jumlah hasil tangkapan nelayan. Tujuan penelitian adalah menganalisis keragaan perikanan tangkap seperti sebaran jumlah alat tangkap, jumlah kapal penangkap ikan, dan daerah penangkapan ikan di perairan Kabupaten Tangerang. Data keragaan perikanan tangkap dianalisis secara deskriptif, dan pemetaan spasial dianalisis menggunakan sistem informasi geografis kelautan. Hasil penelitian menunjukkan jumlah alat penangkapan ikan di Kabupaten Tangerang sekitar 22.495 unit yang didominasi alat tangkap bubu sekitar 18.750 unit. Sebaran alat penangkapan ikan terbanyak tedapat di Desa Dadap, Ketapang dan Tanjung Kait. Jumlah kapal penangkap ikan di Kabupaten Tangerang sekitar 3.212 kapal yang didominasi kapal berukuran <5 GT yaitu sekitar 2.125 kapal, berukuran 5 – 10 GT sekitar 905 kapal, dan berukuran 10 – 30 GT sekitar 182 kapal. Sebagian besar kapal terdapat di Pusat Pendaratan Ikan (PPI) Kronjo, PPI Cituis, dan Desa Dadap. Daerah penangkapan ikan utama kapal <5 GT mengalami pergeseran ke arah timur laut Kabupaten Tangerang. Daerah penangkapan ikan utama kapal > 5 GT berada di Pulau Lancang, Pulau Laki, Pulau Bokor, dan Pulau Pari. The waters of Tangerang Regency have considerable potential for fish resources. At present, the influence of coastal activities and fishing patterns has resulted in fishing dynamics that affect the amount of fishermen’s catch. The research objective is to analyze the fisheries performance, such as the distribution of the number of fishing gears, the number of fishing vessels, and the fishing grounds in Tangerang Regency waters. Capture fisheries performance data were analyzed descriptively, and spatial mapping was analyzed using a marine geographic information system. The results showed that the number of fishing gear in Tangerang Regency was around 22,495 units, dominated by around 18,750 units of traps. The largest distribution of fishing gear is in the villages of Dadap, Ketapang, and Tanjung Kait. The number of fishing vessels in Tangerang Regency around 3,212 vessels, dominated by <5 GT boats size, namely 2,125 boats, 5-10 GT around 905 boats, and 10-30 GT around 182 boats. Most of the vessels were based in PPI Kronjo, PPI Cituis, and Dadap Village. The main fishing grounds for vessels <5 GT has shifted to the northeast of Tangerang Regency. The main fishing grounds for vessels over 5 GT are on Lancang Island, Laki Island, Bokor Island, and Pari Island. ","PeriodicalId":55669,"journal":{"name":"Jurnal Penelitian Perikanan Indonesia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41441693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data bulanan selama Maret sampai Desember 2018 dikumpulkan dari TPI Lampulo (Banda Aceh) dan Sibolga (Sumatera Utara), bertujuan untuk memperoleh informasi dan menganalisis tentang dimensi alat tangkap, daerah penangkapan ikan, komposisi hasil tangkapan, frekuensi ukuran ikan dan upaya penangkapan (hasil per unit upaya, CPUE). Selanjutnya data biologi ikan dianalisis dengan metode analitik. Hasil penelitian menunjukkan perubahan dimensi pukat cincin yang digunakan. Jenis ikan layang (Decapterus macarellus) merupakan hasil tangkapan dominan yang didaratkan di PPS Lampulo (Banda Aceh) dan PPN Sibolga (Sumatera Utara), masing-masing sebesar 82,2% dan 51 % dari total produksi ikan tahun 2018 di daerah tersebut.

Ketersediaan data dan informasi secara spasial dan temporal adalah faktor keberhasilan dalam kegiatan penangkapan dan sejauh ini belum tersedia secara rinci. Penelitian ini bertujuan mengkaji lokasi dan waktu penangkapan rajungan oleh nelayan Betahwalang dalam dua musim, yaitu musim angin barat (musim hujan) dan musim angin timur (musim kemarau). Data diperoleh dari wawancara terhadap 30 responden per jenis alat tangkap (bubu, arad, dan jaring insang dasar). Informasi tentang lokasi dan waktu penangkapan rajungan diplot langsung pada sebuah peta grid berukuran 1 km x 1 km. Selanjutnya, informasi dari peta tersebut dipindahkan ke peta grid berukuran 10 km x 10 km.

Kegiatan penangkapan di waduk ini telah lama dilakukan baik oleh nelayan sekitar maupun luar daerah. Saat ini telah terjadi indikasi adanya penurunan produksi sebagai akibat adanya degradasi sumber daya ikan dan lingkungan serta intensitas penangkapan yang tinggi. Diperlukan upaya pengelolaan untuk meningkatkan produksi ikan di Waduk Malahayu. Salah satu upaya tersebut adalah dengan melakukan penebaran ikan secara rutin baik oleh instansi pemerintah maupun nelayan setempat. Salah satu faktor keberhasilan penebaran ikan terhadap peningkatan produksi adalah jumlah padat tebar yang memadai. Akan tetapi, kajian mengenai jumlah padat tebar yang memadai melalui pendekatan model matematis belum banyak dilakukan. Model matematis mampu memperhitungkan aspek lain seperti penebaran kembali dan penangkapan ke dalam satu kajian model holistik dan analitik. Penelitian ini bertujuan untuk mengestimasi jumlah benih nila yang sebaiknya ditebar. Kondisi populasi ikan nila digambarkan dengan skenario laju pertumbuhan logistik, dengan pertimbangan adanya penebaran dan penangkapan. Hasil menunjukkan bahwa jumlah benih nila untuk ditebar sehingga dapat meningkatkan produksi adalah sekitar 8 ton/tahun atau setara dengan 533.333 ekor/tahun.
