Is it worth it to use brackish water ponds for prawn farming?
This new technology on prawn farming in brackish water ponds incorporates pollution management which constitutes 9% of annual prawn production cost per ha of the farmer. Pollution management is worth the cost considering that a prawn farmer could lose it all during a disease outbreak.
Can a Ulang prawn be grown in a tank?
The macrobrachium rosenbergii is appealing to culture because of its rapid growth performance and ability to survive and grow in turbid water conditions.
