Abstract

This study aims to identify the gastropod diversity in the Gembolo River, Pungging District, Mojokerto Regency. The sampling method used was manual collection (hand picking) at three observation stations, and species identification was conducted based on morphological characteristics. The results showed that five gastropod species belonging to four families were found in the Gembolo River. The diversity index value of 1.06 indicates a moderate level of diversity. The dominance index value of 0.42 suggests that no single species dominates the gastropod community. In conclusion, the gastropod diversity in the Gembolo River is categorized as moderate, with no dominant species observed. Keywords: Biodiversity, Gastropods, Freshwater Snails, Morphometry

Abstract

This study aims to describe the presence of Pomacea canaliculata in Tulangan District, Sidoarjo Regency, and to identify its morphological and morphometric characteristics. The method used was purposive sampling, with specimens collected from three different locations: Saman Hudi River, Kepatihan Village rice fields, and Kenongo Village rice fields. Morphological observations included shell coiling direction, shell shape and color, aperture shape, umbilicus type, and operculum type. Morphometric measurements covered shell height and width, tentacle length, body whorl height, and aperture height and width. The results showed that Pomacea canaliculata shells are round, with yellowish-brown to dark brown coloration and spiral line patterns following the coiling direction. The aperture is oval to elongated crescent-shaped, slightly widened at the base, with a slit-type umbilicus, and a corneous operculum with concentric rings and a subcentral nucleus. Based on morphometric analysis using Principal Component Analysis (PCA), the largest Pomacea canaliculata individuals were found in Kepatihan Village rice fields, while the smallest were found in Saman Hudi River. Differences in morphology and morphometry among locations indicate significant environmental influences, including habitat conditions and natural selection.

Abstract

Tingginya intensitas penangkapan kerang darah (Anadara granosa) di Muara Sungai Banjar Kemuning berpotensi mengganggu keberlanjutan populasi apabila tidak didukung data biologi yang memadai. Penelitian ini bertujuan untuk menganalisis tingkat kematangan gonad (TKG), indeks kematangan gonad (IKG), serta keterkaitannya dengan kondisi lingkungan perairan. Penelitian dilakukan secara deskriptif kuantitatif dengan pengambilan sampel pada tiga stasiun berdasarkan intensitas penangkapan. Parameter yang diamati meliputi TKG, IKG, serta kualitas air (suhu, salinitas, pH, dan oksigen terlarut). Hasil penelitian menunjukkan bahwa sebagian besar individu berada pada TKG II (22 dari 46 individu), yang menunjukkan fase perkembangan gonad awal hingga pertengahan. Nilai IKG meningkat seiring bertambahnya TKG, dengan kisaran 2,5–7,0% pada jantan dan 2,0–6,0% pada betina. Parameter kualitas air berada dalam kisaran optimal (suhu 29,8–30,9°C; salinitas 33–34 ppt; pH 8,0–8,3; DO 6,58–6,97 mg/L) yang mendukung perkembangan gonad. Namun, rendahnya proporsi individu pada TKG IV (4 individu) menunjukkan bahwa tekanan penangkapan diduga menjadi faktor utama yang memengaruhi belum optimalnya kondisi reproduksi populasi. Kata Kunci: Anadara granosa, tingkat kematangan gonad, indeks kematangan gonad, kualitas air
