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

Fish fauna survey biodiversity was conducted in Ujung Kulon National Park, Pandeglang-West Java, to reveal fish diversity in mangrove ecosystem. Samples were caught using electrofish (12 V 10A), gill net (mesh sized 1-1.5cm) and fishing tackle.Result showed that there were 58 fish species belongs to 34 families and 43 genera Gobiidae was a dominant famili with 8 spesies, followed by Apogonidae, Chandidae, Lutjanidae and Serranidae each with 3 species. Cigenter river has highest diversity with H = 2.74, E=0.930, d = 5.346. Serinding fish (Ambassis dussumieri) was the highest abundance compared to others.

Abstract

Brek fish (Barbonymus balleroides) is a consumption, fish that is widely used by people around the River. The population has started to decline, but not yet cultivated. Therefore, research has been conducted as a basis for its domestication, including growth patterns and condition factor of Brek Fish. The total length (TL) of each individual was measured using a digital caliper with an accuracy of 0.05 mm, while the body weight was weighed using an analytical scale with an accuracy of 0.0001 g. the data obtained were analyzed by linear regression found in the microsoft excel program. The results showed that the growth pattern of brek fish was allometric negative, the average condition factor value of brek fish (B. balleroides) was 1.026. The author hopes this research can be used as basic biological information to support the conservation of Brek Fish (B. ballerodes).

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.

Abstract

Kegiatan antropogenik memicu pencemaran air di pantai Teluk Jakarta, yang dapat mengancam keberadaan stok ikan belanak (Planiliza subviridis) di perairan tersebut. Penelitian ini bertujuan untuk mengkaji biologi reproduksi ikan tersebut di perairan Pantai Cilincing. Pengambilan sampel dilakukan selama 6 bulan (Februari-Juli 2023) di perairan tersebut menggunakan alat tangkap jaring insang berukuran mata jaring 0,5-1,5 inchi. Total sampel ikan belanak yang terkumpul sebanyak 204 ekor (jantan 123 ekor dan betina 81 ekor), dengan distribusi ukuran panjang 15,50-26,25 mm. Hasil penelitian menunjukkan bahwa nilai nisbah kelamin (J/B) adalah 1,5:1. Berdasarkan tingkat kematangan gonad, ikan belanak cukup banyak ditemukan dalam keadaan matang gonad dan spent pada bulan Juni-Juli. Nilai rataan Indeks Kematangan Gonad (IKG) ikan belanak terendah dan tertinggi adalah pada bulan Mei dan Juli (jantan), dan pada bulan April dan Juli (betina). Indeks kematangan gonad ikan belanak pada betina lebih tinggi daripada jantan. Ukuran pertama kali matang gonad pada ikan belanak mulai dari TKG IV pada ukuran 163-175 mm (jantan) dan 150-162 mm (betina). Musim pemijahan terjadi pada bulan Juli dengan potensi reproduksi cukup tinggi. Fekunditas ikan belanak berkisar 267.333-956.676 butir telur. Berdasarkan distribusi telurnya ikan belanak diduga memiliki tipe pemijahan total spawner.

Abstract

Arowana (Scleropages spp.) as an ornamental fish native to Indonesia has experienced a population decline. Whereas the market demand for arowana never subsides. Bornean arowana and Papuan arowana, both of which must be immediately conserved so that their populations can increase again. The purpose of this paper is to reveal some aspects of their biology, threats and conservation efforts. Various efforts to conserve arowana have been made as well as the role of the government with binding regulations. It is just waiting for the implementation to implement the existing regulations, and the rule of law in the event of a violation.

Abstract

A single specimen of Bostrychus scalaris was collected from the mangrove estuary of Banyuasin Regency, South Sumatra, Indonesia. The species was originally described as a new species based on a single specimen collected from the disturbed mangrove site in Sementa River, Selangor State, Malaysia. Subsequently, the species was known to have been distributed in Singapore based on a watercolour painting by a French naturalist also in Mekong River in Soc Trang Province, Vietnam. The present specimen of B. scalaris represents the first record of the species from Indonesian water and southernmost record of the species.
