dc.description.abstractThis paper aims to determine optimum stock density for rice-crayfish rearing in controlled environment. Juvenile freshwater crayfish (Pontastams ieptodady/us) obtained in the laboratory condition from female freshwater crayfish were stocked into rice planted artificial pond at different stock densit ies (25 individuals m(-2), 50 individuals m(-2), and 100 individuals m(-2)) for the assessment of paddy field areas in terms of field fisheries in Turkey. Results showed that the best survival rate (72%) and growth for juvenile freshwater crayfish in point of length and weight has been observed at the stock density of 25 individuals m(-2). In addition, statistically significant difference has been found between this stock density and the other stock densities (p<0.05). The maximum survival rate was observed as 72% at the stock density of 25 individuals m(-2). The results of this study are significantly different when compared with Other feeding researches on juvenile freshwater crayfish in Turkey. The stock density of 25 individuals m(-2) should be applied to gain maximum yield in rice- crayfish rearing experiments suggested as an alternative met hod for crayfish rearing. This paper. the first study on the investigation of different stock density for rice-crayfish rearing, will shed light on the further researches.
