4.2 Overview of Aquaculture Methods and Practices. A number of aquaculture practices are used world-wide in three types of environment (freshwater, brackishwater, and marine) for a great variety of culture organisms. Freshwater aquaculture is carried out either in fish ponds, fish pens, fish cages or, on a limited scale, in rice paddies. Aquaculture is sufficiently expressive and multifaceted. It includes the following aspects: (1) The type of organism cultured. For example, the culture of fish, prawn, oyster, mussel, sea­weed, etc. (2) The type of culture technique, such as pond culture, raceway culture, cage culture, pen culture, raft culture, etc. ADVERTISEMENTS:.
