Abstract :The study was aimed to examine a snail organic culture system and describe the cultivation properties of Cornu  aspersum. The environmental parameters of the culture system and their effects on the growth and mortality rates of C.  aspersum were determined between November 2014-October 2015. Snails were fed Spinacia sp. insert ignore into journalissuearticles values(spinach);, Urtica sp.  insert ignore into journalissuearticles values(nettles);, Brassica oleracea sp insert ignore into journalissuearticles values(cabbage); and formulated diet. The feeding and growth rates increased with increasing  temperature. Shell height growth rate was the highest in spring while the live weight growth rate was the highest in  summer. Mortality rate of the baby snail was higher between November 2014 and May 2015 due to stress conditions  such as handling and varying temperatures during their first stages of life. High mortality observed in adults could be  associated with the spawning activity of the matured snails that caused physiological exhaustion. The result showed  that the best culture cycle for C. aspersum was from spring to autumn in Black Sea region and in order to prevent postreproductive  mortality, snails reached to marketable size should be harvested.
