Hi silverton,
I can imagine your appetite was hit by this experience. Thanks for sharing it. Yes, it pertains for prawns and shrimps. The shrimp farms in Thailand actually focussed on the black tiger prawns but then they went over to the white Pacific shrimp (Giant Tiger Prawn) due to higher yields, disease-resistancy and a faster growth. You can calculate 120 day until they can be sold - allowing up to three cycles each year.
