    The culture of finfishes in cages has been practiced for years in countries like Cambodia, Vietnam, Indonesia, Thailand, Malaysia, Singapore and Hongkong. Cage was first used as a holding facility for fish. True cage culture was said to have started in 1243 in China. Use of modern cage materials like synthetic nets, woods and metals started in early 1960’s. The size and shape of the cages are very important for the growth and production of the fishes/ shell fishes living inside it. The design will vary depending on the selected site. The constructed cage must withstand the force of wind and wave while holding the stock safely. The cage must be safe, secure and easy to manage. Circular cage bags make the most efficient use of materials, and thus have the lowest costs per unit volume. Shape is likely to influence effective stocking densities and swimming behaviour, which in turn can influence production. Fish cages can be constructed from a variety of materials. All materials used for the cage should be durable, nontoxic, and rustproof.
