Status Stok Ikan Pepetek, Leiognathus equula (Forsskal, 1775) Berdasarkan Rasio Potensi Pemijahan di Teluk Palabuhanratu

Abstract

Ikan pepetek, Leiognathus equula (Forsskal, 1775) merupakan salah satu jenis ikan demersal yang banyak didaratkan dan bernilai ekonomis di PPN Palabuhanratu. Penelitian ini bertujuan menentukan status stok dan strategi pengelolaan ikan pepetek berdasarkan rasio potensi pemijahan di Teluk Palabuhanratu.. Pengambilan contoh ikan dilakukan pada bulan September 2021 hingga Februari 2022 secara langsung dari hasil tangkapan nelayan menggunakan metode penarikan contoh acak sederhana dengan jumlah total ikan yang diteliti sebanyak 459 ekor. Analisis parameter pertumbuhan menghasilkan panjang asimtotik (L8) ikan jantan dan betina bernilai 215,8 mm dan 201 mm, serta laju pertumbuhan (K) ikan jantan dan betina dengan nilai 0,5 tahun-1 dan 1,4 tahun-1. Ikan jantan memiliki laju eksploitasi (E) lebih besar dibandingkan ikan betina dengan nilai 0,84 dan 0,72 (E > 0,5). Spawning Potential Ratio (SPR) ikan pepetek di Teluk Palabuhanratu tergolong rendah dengan nilai 17–32% (SPR < 40%), sehingga status stok ikan pepetek mengalami kondisi penangkapan berlebihan dan recruitment overfishing. Pengelolaan ikan pepetek berdasarkan keputusan taktis berupa tindakan catch control, size control dan gear control.

Common ponyfish, Leiognathus equula (Forsskal, 1775) is one of the demersal fish that is frequently landed and has economic value in PPN Palabuhanratu. This study aims to determine the stock status of common ponyfish based on the spawning potential ratio in Palabuhanratu Bay. Fish samples was collected from September 2021 to February 2022 directly from the catch of fishermen using the simple random sampling method with a total number of 459 fish. Analysis of growth parameters resulted in asymptotic length values (L8) of male and female fish for 215,8 mm and 201 mm, and growth rate values (K) of male and female fish with values of 0,5 year-1 and 1,4 year-1. Male fish have a higher exploitation rate compared to female fish, with values of 0,84 and 0,72. Spawning Potential Rasio (SPR) of common ponyfish in Palabuhanratu Bay is low with values ranging from 17–32% (SPR < 40%), so that the stock status of common ponyfish is experiencing overfishing and recruitment overfishing condition. Management of Common ponyfish based on tactical decisions in the form of catch control, size control, and gear control.
