Shrimp farming occurs in both marine and fresh water environments. They are located all over the world in more than 50 countries, but the US ponds are the cleanest and the ponds in Asia are the dirtiest.
There are two cycles of shrimp farming and the first one is putting all the nursery shrimp in a nursing pond and then when they hatch they use a net to catch them all in the little ponds. Sometimes they even drain the ponds to get all the shrimp as another technique.
Types of Shrimp
Shrimp farming only catches shrimp and not any other animals. There is white, brown, pink, and giant blue shrimp in these ponds.
The process of shrimp farming benefits the environment because it's the easiest way to collect the shrimp and it's fast and cheap and doesn't destroy anything around them if they use the nets. If they drain the ponds the land all around them gets destroys and erosion happens, so the ponds are taking up a lot of land and destroy a lot of land.
1-1.5 million coastal lands have been changed into shrimp ponds or just aquaculture lands. improving the size of the ponds and the designs, reduction of water exchange, balance between mangrove and shrimp pond, and capacity of the water are all ways to mitigate shrimp ponds.
The government regulates the shrimp farms but has less powers now a days because it is mostly controlled by the environment regulatory networks (ERN). It gives you more of a complex way to think of regulation.
Total percent of by catch discarded from all the areas of the world is 85%. It all depends on the temp of the water that is around the fish/shrimp.
