Production method
Culture, bottom, Culture, suspension
Rating summary
Scallops farmed in the UK (Scotland) in suspended rope culture and bottom culture have little environmental impact and do not require any commercial feed sources as they get all of their nutrient requirements from the surrounding water. Scallop aquaculture is entirely sea-based and habitat concerns are minimal. Scallop culture generally does not involve the use of chemicals and there is no concern about the impact of effluents. Spat used for farming are either collected from the wild or settle naturally and research into development of a hatchery is ongoing. Disease risk and parasite interactions are thought to be minimal and do not threaten regional level populations. Currently, no independently certified scallops are available.Rating last updated March 2024.
