Snakehead fish are widely farmed in Southeast and East Asia as air-breathing predatory species. Their unusual biology and predatory nature create specific welfare management requirements.
Snakehead welfare benefits from their remarkable physiological tolerance of poor conditions, but this tolerance should not be mistaken for freedom from welfare needs. Chronic poor water quality causes stress and disease susceptibility even in air-breathing fish. Cannibalism at mixed sizes requires management through regular grading. Their hardy nature makes live transport feasible but does not eliminate the welfare compromise of prolonged transport. Improving harvesting and slaughter methods for this commercially important species would reduce welfare harm at the terminal production stage.
