Fish farming systems are diverse methods used to raise fish in controlled environments, providing a reliable source of seafood. Common systems include pond aquaculture, where fish are raised in natural or artificial ponds, cage systems placed in natural water bodies, and advanced Recirculating Aquaculture Systems (RAS), which recycle water in closed loops. Each approach offers unique benefits: pond and cage systems are suited for large-scale operations in natural water sources, while RAS is ideal for high-density farming with minimal environmental impact. Sustainable management in fish farming systems emphasizes efficient water usage, waste management, and responsible feeding practices, reducing reliance on wild fisheries. These systems contribute to food security, supply stability, and sustainable aquaculture growth worldwide, balancing environmental stewardship with increasing seafood demands.
