How Does One Map These Complex Wetlands, Saltpans and Paddy Fields?

I recently went to this place called Mandarmani. The are is severely under-mapped. When I look at the satellite images, its a complex maze of salt pans, paddy holdings, wetlands and water reservoirs for shrimp farming. Ideally each water tank should be drawn out. Any suggestions?

How about
water = salt for salty water,
or with aquaculture = shrimp would imply that it is salt water.

There’s also landuse = salt _pond
