Experiments on polyculture of Sander lucioperca with Chinese Carp
A series of experiments were conducted on the polyculture of Pike Perch Sander lucioperca with silver carp, bighead carp, grass carp and common carp. The experiments were carried out from April to November 2004 in Sefidrood Fisheries Research Station, Guilan Province of Iran. The carp density was 3000 fish individuals per hectare and stocking rates were 60% for silver carp, 10% for common carp, 10% for bighead carp and 20% grass carp. The Pike Perch fingerlings each weighting 2.1 plus or minus 0.254 grams, were released into the polyculture ponds at a rate of 250 individuals per hectare. We recorded survival rates 93.33% and 83.77% for the Pike Perch and the Chinese Carps respectively. During the experiments, the Pike Perch fingerlings attained an average weight of 54.40 plus or minus 13.23 grams. We found significant differences between the results of the Pike Perch polyculture with Chinese carps and those of the common procedures. The total polyculture production was 4446.66 kilograms per hectare as opposed to 3212.8 kilograms in the common procedures.
