 ABSTRACT

Neritina turrita (Gmelin 1791) along with other Neritina, Clithon, Septaria, and other fresh-water snails are popular animals in ornamental aquarium trade. The need for laboratory-bred animals, eliminating the potential biohazard risks, for the ornamental aquarium trade and the growing demand for animal model systems for biomedical research reasons the work for optimising a successful breading protocol. The initial results demonstrate N. turrita as tough animals, surviving fluctuations in pH from 5 to 9, and shifts from a fresh-water environment to brackish (2 - 20 ppt), to sea-water (35 ppt) salinities. The females laid over 630 (at salinities 0, 2, 10 ppt and temperatures of 25 - 28oC) white oval 1 by 0.5 mm egg capsules continuously within 2 months after collecting semen from several males. Depositions of egg capsules are set apart 6 +/-3 days, and consist on average of 53(range 3 to 192) egg capsules. Production of viable veligers was recorded under laboratory conditions.
