A Study on Determining the Ideal Stock Density of Freshwater Crayfish (Pontastacus leptodactylus) in Polyculture with Rice (Oryza sativa L.)
Abstract
This paper aims to determine optimum stock
density for rice–crayfish rearing in controlled environment. Juvenile
freshwater crayfish (Pontastacus
leptodactylus) obtained in the laboratory condition from female freshwater
crayfish were stocked into rice–planted artificial pond at different stock
densities (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
method 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.
