Abstract

Abstrak. Telah dilakukan penelitian tentang pertumbuhan ikan seriding Ambassis gymnocephalus di perairan TN. Ujung Kulon dan SM. Muara Angke. Tujuan penelitian ini untuk mengetahui hubungan panjang berat dan faktor kondisi. Ikan ditangkap dengan jaring insang (diameter mata jaring = ¾ inch, 1 inch, 1,5 inch dan 2 inch) dan jala (diameter mata jaring = 1 cm dan 2 cm). Hasil yang diperoleh hubungan panjang berat yaitu nilai R untuk jantan 97,9% dan betina 99,0% di TN. Ujung Kulon dan di SM. Muara Angke nilai R 87,8% untuk jantan dan betina 88,4%. Pola pertumbuhan alometrik positif terjadi di TN. Ujung Kulon, sedangkan alometrik negatif di SM. Muara Angke. Nilai faktor kondisi pada 2 lokasi relatif mendukung. Kata kunci: mangrove, panjang-berat, faktor kondisi, seriding, TN. Ujung Kulon, SM. Muara Angke

Abstract

Telah dilakukan penelitian di Muara sungai Bojong Langkap dan Ciperet,Segara Anakan Cilacap. Penelitian ini bertujuan untuk menentukan ragam jenis ikan mangrove. Dari hasil penelitian tersebut berhasil ditemukan 28 jenis ikan yang termasuk ke dalam 24 marga dan 19 suku. Suku Gobiidae tergolong dominan, dengan 5 anggota jenisnya yang tersebar dise-luruh stasiun penelitian. Sebanyak 37 % jenis ikan berpotensi sebagai ikan hias

Abstract

The survey was conducted at Angke-Kapuk Protected Forest, Penjaringan-North Jakarta. The aim of research was to know of fish based diversity and potency. Fish caught with gillnet (mesh size ¾, 1,5 and 2 inch) and fishnet (mesh size 1,5 and 2,0 cm). The result were recorded 19 species belongs to 18 genera and 14 family. Guppy was dominant spesies, while the potential economic are sepat, bulan-bulan and mullet. Key words: protected forest, potency, fish, angke kapuk

Abstract

The presence and establishment of invasive alien fish species is one of the biggest threats to aquatic biodiversity. The red devil, Amphilopus citrinellus, is one of the emerging invasive species and its occurrence is massively detected in common water bodies in tropical areas such as Indonesia. However, the topic remains under-reported from the small urban lakes. This study aims to present the reproductive characteristics of the fish in Situ Cilodong, a small urban lake in the country, that can be used as a principal reference for population control. The sampling was conducted in June 2021 and May 2022 using a mix of seven mesh-sized gillnets. The results of the length-weight relationship reveal that both the female and male fish perform isometric growth type. The calculated Gonad Somatic Index (GSI) and the histological analysis confirmed that the fish is a multi-spawner species. The results imply that sustainable population control efforts must include intensive catch and engage a participatory approach between the legal authority and the local fishers.
