Abstract

Freshwater gastropods live in lakes, rivers, marshes, springs, and pond drainage. Most freshwater gastropods live submerged, while others prefer stones, aquatic plants, wood, dead leaves, and soft sediment. Some freshwater gastropods inhibit artificial freshwater environments due to environmental changes. Water depth, clarity, and temperature correlate to the number of gastropods in an artificial environment. Water temperature increases food availability, thus leading to abundance. Disturbances and interspecific competition may affect freshwater gastropods, which determines gastropod diversity and abundance. This study identified freshwater gastropod species and the freshwater gastropod diversity were determined at Universiti Putra Malaysia Bintulu Sarawak Campus. This study was conducted at ten different stations in UPMKB. Each station had a 1 -meter-square triplicates. Specimens collected were identified and a total of seven hundred and twenty freshwater gastropods from six different species were found in the study area. Sulcospira collyra, Sulcospira testudinaria, Tylomelania inconspicua, Lissachatina fulica, Paracrostoma sp., and Lymnaea sp.. Tylomelania inconspicua was found in seven stations in the artificial environment with deep ooze and plants. Station 5 has the most species; nine other stations each have two. Station 10 is where you'll find the most individuals. Station 3 has the most species, so it has the highest Shannon diversity index. Station 9 has the lowest Shannon diversity index because it only has 47 individuals. The evenness diversity index is the best at Station 10. The Margalef diversity index, Station 5 has the highest number, and Station 10 has the lowest.
