Description:
Beacaus of increasing genetic variation and avoid of future hazard, monoculture of Iran native shrimp species
, penaeus semisulcatus (green tigershrimp) is considered.
One of the most important problems in monoculture is detection relationshipbetween biological and
nonbiological factors, and thier effects on growth and survival of species.This study was caried out in four ponds
(four ponds 0.4 ha). According to results, this species of shrimp needs to quantiative foods , otherwise it caues
canibalism, abnormal distribution, in weight distribution diagram of shrimp and reduction of production in
squere unit. Amongindependent factors such us water temprature, salinity, PH, transparency,water deep and food
consumption rate, four first factors have the mostcorrelation by shrimp weight (r2=0.922).Shrimps weight
variation in 3 Range,25-28, 28-31and more them 31 degree centigrade were studied. There wassignificance
difference in shrimp rate variation in 3 ranges which werementioned (P〈0.05). Shrimp had best growth in 25-28
degree centigrade.
