The effect of stocking density on productions of Super intensive white shrimp (Litopenaeus vannamei) cultured in fibreglass tanks
Shrimp is a main commodity in aquaculture industrialization in Indonesia. The objective of the research was to assess the effect of stocking density on the growth.
The experiment was conducted at Punaga Research Station, Takalar Regency using five fiberglass tanks, diameters 5.0 m, height 1.5 m and filled with 20 m3 sea water. Stocking densities applied in this study were: A=600 ind./m3, B=1000 ind./m3, C=1240 ind./m3, D=1860 ind./m3 and E =2450 ind./m3 with no replications. The samples used in this study were PL-11 then were reared for 80 days. During the experiment, the shrimp were fed with 10-3% of biomass per day using pelleted commercial feed. The result showed that growth rate, production (kg), survival rate (%), productivity (kg/m3) and feed conversion ratio of each treatment were A= 10.0 g/ind , 111 kg, 87,90 %, 5.55 kg/m3 and 1.5, B=9.8g/ind.,148 kg, 75.5%, 7.45 kg/m3 and 1.35, C=8.85 g/ind., 161 kg, 73.40%, 8.05 kg/m3 and 2.03, D= 8.33 g/ind., 203 kg, 66.00%, 10.15 kg/m3 and 1.83 and E=8.00 g/ind., 180 kg, 37.8%, 7.5 kg/m3 and 2.22, respectively.
Shrimp growth with different stocking density on super intensive shrimp farming tended to be better at the density of 1000 ind./m3 to productivity, growth and feed conversion ratio.
