Abstract
The freshwater pulmonate snail Lymnaea
acuminata is hermaphroditic snail found abundantly in various kinds of
water bodies. It acts as a vector snail for various larval trematode pathogens.
Laboratory observations were carried out to quantify the impact of infection on
fecundity. It was aim to study the effect of cercarial infection on fecundity
of host snail. Observation made on Size dependent egg-laying activity of the
infected snail, during period of patency. Different sized animals shell
lengths ranging from 5±1mm, 10±1mm, 15±1mm and 20±1mm were sorted out and
maintained separately in the dechlorinated tap water under laboratory
conditions. It was observed that cercarial larvae affect the host’s
reproductive capacity and minimizing its fecundity. These finding are important
and throws light in the field of reproductive physiology of the intermediate
host snail L. acuminata. These experimental data can be used to confirm
that snail populations are regulated by host parasitic system.
