New paradigm for controlling EMS/APHNS in intensive P. vannamei Boone 1931 culture ponds

Since 2014 a gradual paradigm shift has been taking place in Thailand where the farmers have changed the dynamics of their ponds to maximize diversity to control Vibrio and prevent APHND/EMS outbreaks. The objective is a rather simple one to keep the pond bottoms clean of sediments and sludge. To achieve this farm modules can use a combination of recirculation and flow-through water exchange to maintain a low-risk sustainable culture system. There are four major components that the new� farm design incorporates into the strategy to maintain clean pond bottoms: reduction of grow-out pond size increased reservoir to grow-out pond ratio increased aeration/energy capacity and construction of a shrimp toilet at the center of the pond. The most significant shift in strategy is the reservoir to grow-out ratio. Traditional farms that were once 20 reservoirs and 80 production were changed to 60 reservoir and 40 grow-out capacity. Transitioning a traditional farm into an intensive controlled and sustainable shrimp toilet� culture system may be the best solution to overcome APHND Vibriosis and viral diseases.

Abstract

Since 2014 a gradual paradigm shift has been taking place in Thailand where the farmers have changed the dynamics of their ponds to maximize diversity to control Vibrio and prevent APHND/EMS outbreaks. The objective is a rather simple one to keep the pond bottoms clean of sediments and sludge. To achieve this farm modules can use a combination of recirculation and flow-through water exchange to maintain a low-risk sustainable culture system. There are four major components that the new� farm design incorporates into the strategy to maintain clean pond bottoms: reduction of grow-out pond size increased reservoir to grow-out pond ratio increased aeration/energy capacity and construction of a shrimp toilet at the center of the pond. The most significant shift in strategy is the reservoir to grow-out ratio. Traditional farms that were once 20 reservoirs and 80 production were changed to 60 reservoir and 40 grow-out capacity. Transitioning a traditional farm into an intensive controlled and sustainable shrimp toilet� culture system may be the best solution to overcome APHND Vibriosis and viral diseases.
