Abstract

Nelayan di Pulau Panggang dan Kepulauan Seribu sering melakukan operasi penangkapan ikan dengan menggunakan alat tangkap pancing ulur. Penangkapan ikan dengan pancing ulur dinilai efektif dalam menangkap ikan karena ramah lingkungan. Namun demikian, penelitian yang menyatakan seberapa selektifnya alat tangkap ini dengan menunjukkan komposisi dan indeks keanekaragaman hasil tangkapan alat tangkap pancing ulur masih sedikit. Kurangnya penelitian ini mengakibatkan kekurangan data sebagai dasar untuk pengambilan kebijakan pengelolaan sumber daya. Tujuan penelitian adalah menghitung komposisi spesies hasil tangkapan dan keanekaragaman hasil tangkapan pancing ulur di Pulau Panggang, Kepulauan Seribu. Penelitian ini dilakukan dengan menggunakan analisis deskriptif untuk menghitung komposisi jenis tangkapan dan keanekaragaman hasil tangkapan alat tangkap pancing ulur dengan menggunakan indeks keanekaragaman Shannon-Wiener. Alat tangkap pancing ulur di Pulau Panggang, Kepulauan Seribu berhasil menangkap 10 jenis ikan pelagis dan demersal, yaitu tenggiri (Scomberomorus commerson), layaran (Istiophorus sp), tongkol (Auxis thazard), lemadang (Coryphaena hippurus), cendro (Tylosurus crocodilus), cucut (Rhizoprionodon acutus), dan ikan gabus (Channa striata). Sementara itu, ikan demersal yang cenderung hidup di dasar laut terdiri dari ikan kakap (Lutjanus argentimaculatus), lencam (Lethrinus sp), dan ikan kerapu (Ephinepelus sp). Jenis ikan yang paling banyak tertangkap adalah ikan tenggiri (33%), sedangkan ikan budun merupakan jenis ikan yang paling sedikit tertangkap (1%). Indeks keanekaragaman menghasilkan nilai H' = 1,96, artinya keanekaragaman hasil tangkapan pancing ulur di Pulau Panggang termasuk dalam kategori sedang. Nilai ini menunjukkan bahwa keanekaragaman alat tangkap tergolong tinggi, tetapi selektivitasnya tergolong rendah.

Abstract

This study aims to investigate the food habits of green lobsters (Panulirus Homarus) when fed with natural feed rich in calcium and phosphorus, and to assess their growth performance, survival rate, and water quality in relation to different feeding treatments. The research was conducted in 2024 at the Marine Station of Pangandaran University, located in Pangandaran Regency. The study utilized a Complete Random Design (RAL) with four different feeding treatments over 6 x 10 days: A (80% anchovy feeding), B (100% anchovy feeding), C (80% rebon feeding), and D (100% rebon feeding). The parameters observed include Growth Rate based on Length (LPP) and Weight (LPB), Survival Rate (SR), and Water Quality. Additionally, natural feed habits were monitored using the AI Smart Lobster Culture version 1. The results showed that lobsters fed with 100% anchovy and rebon (treatments B and D) exhibited the highest weight increase, with values of 61.4 and 65.1, respectively, while treatments A and C showed no significant differences. The Survival Rate (SR) across all treatments (A, B, C, and D) was excellent, with an SR of 96%. The findings indicate that both anchovy and rebon, rich in calcium and phosphorus, are effective in supporting lobster growth and survival. In conclusion, this study demonstrates that feeding green lobsters with 100% calcium and phosphorus-rich feed, such as anchovies and rebon, promotes optimal growth and survival, highlighting the importance of feed composition in lobster culture.
