Lola (Truchus niloticus) is one of the largest sea snails that lives in the shallow water in Eastern Indonesia and the Pacific. In Saparua Island (Central maluku), lola population tends to decline due of its exploiation for industrial need. The aim of this study is to determine tha reproductive potential of lola snail in Saparua Island, Central maluku. Lola snails were collected from six location i.e Booi, Haria, Ullath, Ouw, Itawaka and Nolloth (03.29-03.810 LT degree and 128.32-128.43 BT degree). In each location a strip transect 100 x 2 m was made perpendicular to the coastline started from the lower tide level. Lola snail populations were grouped into different age classes based on the shell diameter using Bhattacharya method. The reproductive potentioal of lola snail was analyzed by the value of the net reproductive rate. Ginad histology analyses were made by using paraffin emthods and stained by Ehrlich's Haematoxylin-Eosin. The results showed that the net reproductive rate of lola population is 226 individuals and its generation time is 2.88 years. The histological observations showed that the oocyte consist of proliferation, early developing and mature stages.
