Abstract

Ikan pepetek (Leiognathus equula) merupakan salah satu ikan demersal yang banyak ditangkap di perairan pesisir Cilincing dan memiliki nilai yang cukup penting karena dikonsumsi oleh sebagian besar masyarakat Cilincing baik dalam bentuk segar maupun kering. Penelitian ini bertujuan untuk menganalisis aspek reproduksi ikan tersebut. Data sampel yang dikumpulkan meliputi panjang total, berat, dan aspek reproduksi. Penelitian ini dilakukan pada bulan Maret-Juli 2023. Sampel ikan ditangkap menggunakan alat tangkap jaring insang (ukuran mata jarring 1-2 inci). Hasil penelitian diperoleh total 150 ekor ikan pepetek (52 ekor jantan dan 98 ekor betina), hubungan panjang-berat ikan adalah W = 0.1682L2.0979 (jantan) dan W = 0.0169L2.9941 (betina). Tingkat kematangan gonad ikan pepetek betina menyebar dari TKG III sampai TKG IV, dan TKG ikan pepetek jantan menyebar dari TKG I sampai TKG IV. Berdasarkan tingkat kematangan gonad dan indeks somatik gonad, pemijahan terjadi sekitar bulan Juni dan Juli. Fekunditas ikan pepetek berkisar antara 108.287-362.667 telur. Diameter telur berkisar antara 0,18-0,514 mm, berdasarkan sebaran telur, ikan pepetek diperkirakan memiliki tipe pemijahan total.

Abstract

Information on the fish biodiversity of the Cimandiri Watershed is incomplete, and human activities and anthropogen-ic impacts pose a significant threat to this biodiversity. The purpose of this study was to assess the biodiversity of fish in the Cimandiri Watershed. The results indicated that fish biodiversity in the area included 104 species belonging to 49 families. There were 26 species in the upstream area, 47 species in the middle area, and 61 species in the downstream area. Forty-three species were native to Indonesia, and 7 of the native fish were endemic to the area. There were 11 introduced species belonging to 6 families. Analysis of biodiversity status shows that 4 species were threatened, 2 spe-cies were near-threatened, 76 species were less considered, and 18 species have not yet been evaluated. Among the economically important species present, the eel is the most common in the Cimandiri Watershed. This study has re-vealed the profile of the Cimandiri Watershed, the characteristics of its ecosystem, fish biodiversity, economically im-portant fish species, the conservation status of fish species, and the threats to the fish biodiversity within it.

Abstract

Glyptothorax platypogon is freshwater fish, it’s potential to be an ornamental fish. Its need to be protected from extinction because population in other areas is till abundance. G. platypogon has reported that it's in Serayu River and based on pre-research observations found in Ringin River, Semarang, Central Java. The differences in the geographic location of the two rivers have the potential for the emergence of morphological variations of G. platypogon. Research on the morphology study of the G. platypogon from the Serayu River in Banjarnegara and the Ringin River has been conducted. This study describe morphological variations and provide information about the phenetic relationship between them. Sampling was carried out at Serayu River and Ringin River by direct observation and collection methods in the Field then continued at the Structure Laboratory of Biology Department State Islamic University Walisongo for observed morphometric and meristic,including 43 characters. Data was analyzed with the Kruskall Wallis test, Mann Whitney U test, PCA (Principal Component Analysis) and UPGMA (Unweighted Pair Group Arithmetic Average Method). The result showed that there were high morphological variations in the Allopatric population in Serayu River and Ringin River and there were low morphological variations in the Sympatric population in Serayu river. There were two clad taxa branching groups from Serayu and Ringin population which show morphological variation. UPGMA analysis and Euclidean distance show the population of Serayu River and Ringin River have a close phenetic relationship.
