POTENSI LESTARI IKAN SELAR KUNING (Selaroides leptolepis) DI PERAIRAN SELAT SUNDA (Population Dynamics of Yellowstripe Scad (Selaroides leptolepis) in Sunda Strait)
Abstract
ABSTRACT
Yellowstripe scad included the one of commodity that has an important economic value in the Sunda Strait. Commonly, this species processed by Pandeglang fishermen to be the boiled fish, salted fish, grilled fish, besides it also traded in fresh or frozen fish product. The high market demand can not offset the production of this species from the nature. Therefore, it needed an information about resources of yellowstripe scad in the waters of the Sunda Strait in order to manage it well. The objective of this study was to estimate the maximum sustainable yield (MSY) and the optimum fishing effort (fopt), so that the yellowstripe scad resources in the waters of the Sunda Strait can be utilized optimally and sustainably. Based on the standardization analysis, the purse seine be made the standard fishing gear for estimating the MSY of yellowstripe scad. The yellowstripe scad growth patterns during the study is isometric. Trends of CPUE of the yellowstripe scad fisheries tends to decrease during 2003 to 2013. Then, this species was estimated its maximum sustainable yield (MSY) of 304.50 tons per year, with the optimum fishing effort of 12.478 trips per year. The decline of the catch per fishing effort can indicated that the yellowstripe scad fishing conditions in the Sunda Strait was having the overfishing phenomenon.
Key words: Sunda Strait, sustainable potential, yellowstripe scad

ABSTRAK
Ikan selar kuning termasuk salah satu komoditas perikanan yang memiliki nilai ekonomis penting di perairan Selat Sunda. Jenis ikan ini, selain banyak dimanfaatkan oleh nelayan sekitar Kabupaten Pandeglang sebagai ikan pindang, ikan bakar, ikan asin, juga diperdagangkan dalam keadaan segar maupun dibekukan. Tingginya permintaan pasar tidak dapat mengimbangi produksi ikan tersebut di alam. Oleh karena itu, untuk memperoleh informasi mengenai tingkat pemanfaatan sumber daya ikan selar kuning di perairan Selat Sunda, diperlukan suatu kajian mengenai potensi lestari ikan selar kuning. Tujuan dari penelitian ini adalah untuk mengetahui hasil tangkapan maksimum lestari (maximum sustainable yield atau MSY) serta upaya penangkapan maksimum lestari (fopt) sehingga sumberdaya ikan selar kuning di Perairan Selat Sunda dapat dimanfaatkan secara optimal dan berkelanjutan. Berdasarkan hasil standardisasi, alat tangkap standart yang digunakan adalah purse seine. Pola pertumbuhan ikan selar kuning selama penelitian, yaitu isometrik. Hasil perhitungan CPUE menunjukkan adanya produksi yang cenderung menurun dengan upaya penangkapan yang meningkat dari tahun 2003 sampai 2013. Hasil perhitungan potensi hasil tangkapan maksimum lestari (MSY) diestimasi sebesar 304,50 ton per tahun, dan upaya penangkapan optimumnya adalah 12.478 trip per tahun. Penurunan hasil tangkapan per upaya penangkapan dapat dijadikan salah satu indikasi bahwa kondisi penangkapan ikan selar kuning di Perairan Selat Sunda sedang mengalami gejala lebih tangkap atau overfishing.
