Evaluation of stocking density vannamei shrimp Litopenaeus Vannamei (Boone, 1931) in cultuering with brackish water of Caspian Sea
Recently, the development of aquaculture has focused on the use of seawater, because of freshwater crisis in the world. Whiteleg shrimp (Litopenaeus Vannamei) is one of the most important species for aquaculture development, because of tolerance and adaptation to different ecological conditions. One of the advantages of species in aquaculture, compatibility status is dense in the rearing period. In this study, the effect of different densities (45/m2 , 50/m2 , 55/m2 and 60/m2 ), of primary stock whiteleg shrimp postlarvae (PL12) on the growth and survival rate were evaluated. Brackish water (10.52±0.43 ppt) was providing from Caspian Sea. The experiments were performed in 12 circular concrete pond with a sandy bed (area: 78m2 ) in four treatments and three replications for each treatment. The experiments performed in a 75-day period. In this study, the water temperature was 27.4±1.79°C. The results showed statistically difference in growth parameters and survival rate among experimental treatments (Duncan test, P<0.05). Therefore, with high levels of density, has decreased the amount of weight gain and survival rate (SR), specific growth rate (SGR) and average daily growth (ADG). In addition, the treatments were different variations of FCR (P<0.05) and not depend on the primary stock density of postlarvae. In low density (45/m2 ) were observed the highest growth (SGR=11±0.04 and ADG=0.25±0.01 gr/day/ind.), survival rate and calculate the amount of production per 78m2 equal 43.6±3.3kg (5596±433kg/ha). Therefore, It is possibility that there is commonly increasing primary stocking of density about L. Vannamei postlarvae culture in Iran.

description |
Recently, the development of aquaculture has focused on the use of seawater, because of freshwater crisis in the
world. Whiteleg shrimp (Litopenaeus Vannamei) is one of the most important species for aquaculture
development, because of tolerance and adaptation to different ecological conditions. One of the advantages of
species in aquaculture, compatibility status is dense in the rearing period.
In this study, the effect of different densities (45/m2
, 50/m2
, 55/m2
and 60/m2
), of primary stock whiteleg shrimp
postlarvae (PL12) on the growth and survival rate were evaluated. Brackish water (10.52±0.43 ppt) was
providing from Caspian Sea. The experiments were performed in 12 circular concrete pond with a sandy bed
(area: 78m2
) in four treatments and three replications for each treatment. The experiments performed in a 75-day
period. In this study, the water temperature was 27.4±1.79°C. The results showed statistically difference in
growth parameters and survival rate among experimental treatments (Duncan test, P<0.05). Therefore, with high
levels of density, has decreased the amount of weight gain and survival rate (SR), specific growth rate (SGR)
and average daily growth (ADG). In addition, the treatments were different variations of FCR (P<0.05) and not
depend on the primary stock density of postlarvae. In low density (45/m2
) were observed the highest growth
(SGR=11±0.04 and ADG=0.25±0.01 gr/day/ind.), survival rate and calculate the amount of production per 78m2
equal 43.6±3.3kg (5596±433kg/ha). Therefore, It is possibility that there is commonly increasing primary
stocking of density about L. Vannamei postlarvae culture in Iran. |
