斑节对虾(非洲群体)帆布池养殖试验OA

To investigate the production performance of Penaeus monodon(African population)under tarpaulin ponds culture,including grow-out duration,survival rate,feed conversion ratio(FCR),and feed cost,a farming trial was conducted in 2024 in Wenling,Zhejiang,where 2.1 million juveniles of P.monodon(African popula-tion)were introduced for the first time.The results showed that after centralized nursery rearing and multiple-stage grading culture,the total cultivation cycle lasted 183 days.A total of 28 580 kg of marketable shrimp was harvested,with an average size of 41 tails/kg.The yield of shrimp reached 10.21 kg/m2,the output value was 602.22 RMB/m2,and the profit was 225.61 RMB/m2.These results indicate that despite the relatively long cul-tivation period,this culture model still demonstrates good economic performance.The findings from this trial can provide a reference for the promotion of P.monodon(African population)and for practical canvas-pond aquacul-ture.
