Pomacea sp, parasite, reproductive organsAbstract
Apple snails (Pomacea sp.) are Gastropods in rice field ecosystems that consumed by humans and also play an important role as intermediate hosts for various parasitic worms. One part of the apple snail that is consumed by humans is the reproductive organs, which is an ideal place for parasites to develop because it has high metabolic activity. This study aims to identify the types of parasites and analyze the prevalence of infection in the reproductive organs of apple snails. Sampling and laboratory analysis were conducted in September 2025. The research method used was descriptive with simple random sampling techniques at three stations (inlet, center, outlet) in the rice field area Jabungan Village, Semarang. A total of 30 snails were examined through dissection and microscopic observation. The results showed that there are six genera of parasites infecting the reproductive organs (gonads) of apple snails, consisting of two classes, namely the Trematode class (Opisthorchis, Echinostoma, Fasciola, and Schistosoma) and the Nematode class (Gnathostoma and Trichuris). Prevalence analysis showed that the Opisthorchis and Echinostoma genera dominated with a prevalence value of 100% at all observation stations. The Gnathostoma and Schistosoma genera had fluctuating prevalence rates between 60% and 80%, while Fasciola was found to be the least prevalent (10%-20%). The Trichuris genus was only found at the outlet station with a prevalence of 30%. This research is expected to support public health education programs on the risk of parasites in apple snails.
