An experimental study on the budget of organic carbon in polyculture systems of swimming crab with white shrimp and short-necked clam

The budget of organic carbon (OC) in polyculture systems of swimming crab Portunus trituberculatus, white shrimp Litopenaeus vannamei and short-necked clam Ruditapes philippinarum was studied with land-based enclosures from July 2 to October 3, 2012. Six treatments were designed, including monocultu...

Description
Summary:The budget of organic carbon (OC) in polyculture systems of swimming crab Portunus trituberculatus, white shrimp Litopenaeus vannamei and short-necked clam Ruditapes philippinarum was studied with land-based enclosures from July 2 to October 3, 2012. Six treatments were designed, including monoculture of crab (C), polyculture of crab with shrimp (CS) and polyculture of crab with shrimp and clam (CSB1, CSB2, CSB3 and CSB4). Crab were stocked at 6ind/m2 in all treatments, and shrimp were stocked at 45ind/m2. Short-necked clam were stocked with crab and shrimp in four different densities, i.e., 7.5 (CSB1), 15 (CSB2), 30 (CSB3) and 60ind/m2 (CSB4). Results showed that the yield of crab was the highest in CSB4 system (P
