ABSTRAKIkan kurisi merupakan salah satu ikan ekonomis penting di perairan
Tangerang dan sekitarnya. Intensitas pemanfaatan sumberdaya ikan kurisi akhirakhir
ini semakin meningkat, seiring dengan meningkatnya permintaan akan
komoditas ini terutama untuk bahan surimi. Penelitian bertujuan mengkaji aspek
biologi ikan kurisi (N. peronii), potensi dan tingkat pemanfaatan, serta optimasi
pemanfaatannya di perairan Tangerang. Metode yang digunakan adalah metode
survey dengan sampel ikan kurisi pada alat tangkap cantrang dan apollo. Analisis
parameter populasi digunakan program FiSAT II dan pengkajian potensi lestari
Maximum Sustainable Yield (MSY) dianalisis dengan model surplus produksi.
Optimasi pemanfaatan dilakukan dengan analisis Linier Programing. Hasil penelitian
menunjukkan pola pertumbuhan ikan kurisi bersifat allometrik negatif. Panjang dan
berat ikan kurisi berkorelasi erat. Ukuran panjang pertama kali tertangkap (Lc) 16,34
cm. Parameter pertumbuhan menunjukkan ikan kurisi diperkirakan mampu mencapai
panjang 28,03 cm dengan laju pertumbuhan lambat sebesar 0,49 cm per tahun. Laju
mortalitas lebih besar disebabkan oleh kematian alami. Tingkat eksploitasi masih
berada di bawah nilai optimum dan perlu kehati-hatian dalam pengelolaannya.
Pendugaan MSY dan F-Opt sebesar 494 ton/tahun dan 743 unit alat tangkap standar
cantrang. Dari analisis optimasi menghasilkan jenis alat tangkap yang
direkomendasikan yaitu 743 unit alat tangkap cantrang.
ABSTRACTThreadfin bream is one of the important and high economical fish that can be found
in Tangerang?s waters and its surounding. The use of threadfin bream increases
nowadays, alligned with the increasing demand of these commodities, especially for
Surimi. 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 the
optimization of water utilization in Tangerang.The research method used by the
writer was a survey method using threadfin bream caught by fishing gear named
Cantrang and Apollo as the samples.The writer used FiSAT II program to do the
analysis of population parameters, and used a surplus production model to assess the
Maximum Sustainable Yield (MSY). Linear Programming Analysis was used to
analize the use of optimization. The research?s result showed that the growing pattern
of threadfin bream was negative allometric. There was a close correlation between
the 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 bream
were expected to grow until 28.03 cm long, with a slow growth rate is 0.49 cm per
year. Mortality rate was caused by natural fish death. The level of exploitation below
the maximum value, so it needs to be managed prudentially. The estimation of MSY
and 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 fishing
gears, 743 units of Cantrang fishing gear.;Threadfin bream is one of the important and high economical fish that can be found
