Aquaculture, or fish farming, involves the controlled cultivation of aquatic organisms in natural or artificial environments. It encompasses various species such as finfish, shellfish, and aquatic plants, providing a sustainable alternative to wild fisheries to meet the growing demand for seafood.

Fish farming systems in aquaculture include pond aquaculture, which utilises natural or excavated ponds; cage culture, involving submerged cages in open water bodies; and recirculating systems, which are indoor or land-based systems with controlled water recirculation.

Pond aquaculture offers advantages such as utilising natural or excavated ponds for fish cultivation, thereby minimising construction costs. It provides a natural environment for fish growth and allows for the integration of various species and farming practices.

Tilapia is known for its rapid growth rates and adaptability to various farming systems, making it a popular choice in aquaculture. It can thrive in different environmental conditions, contributing to its widespread cultivation globally.

Cage culture allows fish to be contained and fed in submerged cages in open water bodies, reducing land requirements and minimising environmental impact. It also facilitates efficient feeding and monitoring of fish health, contributing to higher productivity in aquaculture.
