King prawn sustainability varies depending on the species and the region in which they are caught or farmed. Some populations of king prawns are considered to be overfished or facing conservation concerns due to high demand and fishing pressure. Wild-caught king prawns are captured using methods such as trawling, which can have significant impacts on the marine environment and result in bycatch of other species. Fish farming or aquaculture of king prawns is also practiced, but it can have its own set of challenges, such as sourcing sustainable feed and addressing potential impacts on the surrounding ecosystem. Responsible aquaculture practices and sustainable feed sourcing are also vital to reduce the environmental impacts of king prawn farming.
