[ABSTRAK Ikan kurisi merupakan salah satu ikan ekonomis penting di perairanTangerang dan sekitarnya. Intensitas pemanfaatan sumberdaya ikan kurisi akhirakhirini semakin meningkat, seiring dengan meningkatnya permintaan akankomoditas ini terutama untuk bahan surimi. Penelitian bertujuan mengkaji aspekbiologi ikan kurisi (N. peronii), potensi dan tingkat pemanfaatan, serta optimasipemanfaatannya di perairan Tangerang. Metode yang digunakan adalah metodesurvey dengan sampel ikan kurisi pada alat tangkap cantrang dan apollo. Analisisparameter populasi digunakan program FiSAT II dan pengkajian potensi lestariMaximum Sustainable Yield (MSY) dianalisis dengan model surplus produksi.Optimasi pemanfaatan dilakukan dengan analisis Linier Programing. Hasil penelitianmenunjukkan pola pertumbuhan ikan kurisi bersifat allometrik negatif. Panjang danberat ikan kurisi berkorelasi erat. Ukuran panjang pertama kali tertangkap (Lc) 16,34cm. Parameter pertumbuhan menunjukkan ikan kurisi diperkirakan mampu mencapaipanjang 28,03 cm dengan laju pertumbuhan lambat sebesar 0,49 cm per tahun. Lajumortalitas lebih besar disebabkan oleh kematian alami. Tingkat eksploitasi masihberada di bawah nilai optimum dan perlu kehati-hatian dalam pengelolaannya.Pendugaan MSY dan F-Opt sebesar 494 ton/tahun dan 743 unit alat tangkap standarcantrang. Dari analisis optimasi menghasilkan jenis alat tangkap yangdirekomendasikan yaitu 743 unit alat tangkap cantrang. ABSTRACT Threadfin bream is one of the important and high economical fish that can be foundin Tangerang?s waters and its surounding. The use of threadfin bream increasesnowadays, alligned with the increasing demand of these commodities, especially forSurimi. The research is aimed to exercise the biological aspects of threadfin bream(N. peronii); the potential and the number of utilization of it, as well as theoptimization of water utilization in Tangerang.The research method used by thewriter was a survey method using threadfin bream caught by fishing gear namedCantrang and Apollo as the samples.The writer used FiSAT II program to do theanalysis of population parameters, and used a surplus production model to assess theMaximum Sustainable Yield (MSY). Linear Programming Analysis was used toanalize the use of optimization. The research?s result showed that the growing patternof threadfin bream was negative allometric. There was a close correlation betweenthe length and weight of the growing fish with their length when first being caught(Lc) 16.34 cm. Threadfin bream?s growth parameters showed that threadfin breamwere expected to grow until 28.03 cm long, with a slow growth rate is 0.49 cm peryear. Mortality rate was caused by natural fish death. The level of exploitation belowthe maximum value, so it needs to be managed prudentially. The estimation of MSYand F - Opt are 494 tons/ year, and 743 units of standard Cangkrang fishing gear.From the analysis of optimization, it produced the types of recommended fishinggears, 743 units of Cantrang fishing gear.;Threadfin bream is one of the important and high economical fish that can be foundin Tangerang’s waters and its surounding.
