In the market BT and vanna address different segments. BT larger size. Vannamei smaller size but faster thus bigger per year returns for farmers.
Uptick in BT market now is slowly trickling back.
Bangladesh should not be always eying its neighbours and should proudly develop its endemic species. Vannamei culture should be banned from Bangladesh. Would be great branding but do farmers need BT culture economic support then or what…?
