Hutami, Viena Annisa Firdauzy (2017) Analisis Keberlanjutan Sumberdaya Ikan Kurisi (Nemipterus Nematophorus) Yang Di Tangkap Di Perairan Masalembu Yang Didaratkan Di Pelabuhan Perikanan Nusantara (PPN) Brondong, Lamongan, Jawa Timur. Sarjana thesis, Universitas Brawijaya.
Abstract
Ikan kurisi (Nemipterus nematophorus) termasuk jenis ikan demersal, terkadang membentuk gerombolan hidup, terutama pada daerah perairan pantai dengan dasar lunak seperti pasir dengan sedikit lumpur.Termasuk jenis predator dengan makanan utama ikan dan makrofauna lainnya. Dulunya ikan kurisi (N. Nematophorus) merupakan hasil samping (by-catch) dari alat trawl. Di wilayah Utara Jawa, ikan ini sering tertangkap oleh nelayan dengan menggunakan alat jaring tarik (beach seine).Ikan ini bisa mencapai panjang 20 cm, tetapi umumnya tertangkap pada ukuran 15 cm. Tujuan dari penelitian ini adalah mengetahui potensi lestari sumberdaya ikan kuniran di perairan Lamongan, mengetahui status pemanfaatan sumberdaya ikan kuniran, serta menentukan strategi pengelolaan sumberdaya ikan kuniran di perairan Lamongan. Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Analisis keberlanjutan ekologi yang digunakan adalah model surplus produksi melalui pendekatan equilibrium state model yaitu Schaefer Fox dan non equilibrium state modelyaitu Walter Hilborn. Jenis alat tangkap yang dominan menangkap ikan kurisi di Perairan Lamongan adalah alat tangkap dogol. Berdasarkan hasil perhitungan dari analisis model surplus produksi ikan kurisi (Nemipterus nematophorus) didapatkan hasil R square tertinggi pada model Fox yaitu sebesar 95%. Nilai F test sebesar 1,0792E-06 dan nilai R square di regresi sebesar 0.95521 berarti 95%, perubahan dari effort dipengaruhi oleh perubahan nilai CpUE. Sedangkan 5% perubahannya dipengaruhi oleh variabel lainnya. Sehingga model paling cocok digunakan untuk pengelolaan sumberdaya berkelanjutan adalah model Fox. Sehingga diperoleh nilai Fmsy sebesar 3.975 trip/tahun, nilai Ymsy sebesar 10.755,75 ton/tahun dan JTB sebesar 8.605 ton/tahun dengan tingkat pemanfaatan sebesar 99% pada status fully exploited. Jika penangkapan dilakukan terus menerus maka akan terjadi penurunan stok. Sehingga diperlukannya pengendalian upaya penangkapan ikan serta penentuan jumlah unit penangkapan ikan yang diperbolehkan.
English Abstract
Threadfin Bream (Nemipterus nematophorus) is a type of demersal fish, sometimes forming schooling, especially in coastal areas with softly sand and little mud. This fish is categoried as predator species with small fish and other macrofauna as the main food. Usually the curly fish was as by-catch of the trawl. In Java sea, this fish is often caught by fishermen by using beach seine. This fish can reach a length of 20 cm, but is generally caught in size 15 cm. This research was conducted in May 2017 to June 2017 in Brondong Fishing Port, Lamongan Regency, East Java. The purpose of this research are to know the sustainable potential of marine fish resources, to identify the status of the utilization of y Threadfin Bream resources, and to determine the strategy of fish resources management in Lamongan Waters. The method used in this research is descriptive method. The ecological sustainability analysis used is the model of production surplus through the equilibrium state model approach namely Schaefer and Fox and non equilibrium state model that is Walter Hilborn. Result showed that based on surplus production model analysis of Threadfin Bream (N. nematophorus) the highest R square of Threadfin Bream (N. Nematophorus) on Fox model that was 0.95521 with F t value is 1.0792E-06. While R square of Schaefer and Walter Hilborn was only 0,596 and 0.4665 respectively. It meant that the change of effort strongly influenced the change of CpUE value. So the most suitable model used for sustainable resource management is the Fox model. In addition the value of Maximum sustainable Yield (MSY) was 3.975 trip/ year. While the value of Total Allowed Catch (TAC) for effort catch and effort were 8.449 ton/ year and 6.861 respectivly. Another analysis informed that status of the stock was fully exploited because it’s exploitation rate almost reached the Total Allowed Catch (TAC) level (99%). If the catch is done continuously then there will be a decrease in stock. Therefore, it is necessary to control the fishing effort and to determine the number of fishing units allowed.
