| Tóm tắt: | Aquaculture is the cultivation of aquatic organisms (e.g. algae, molluscs, crustaceans, fish) and implicit in this is human intervention that involves some control
over the stock. The degree of human intervention may be limited in extensive
culture of algae and molluscs and in extensive pond culture of fish and crustaceans, but the level of control exerted is high in intensive farming systems.
Intensive culture involves intervention at all phases of the production cycle; from
broodstock maintenance and egg production to the harvesting and marketing of
the finished product (Fig. 1.1). The farmed animals are reared in captivity
throughout their lives; they are held under relatively benign, semi-controlled
conditions and rely on formulated feeds for their nutrition. Aquaculture research
and development (R & D), as it relates to intensive fish farming, currently encompasses all aspects of production and postharvest processing, including culture
unit design, feed delivery systems, water treatment, feed formulation and disease diagnosis and treatment. There is a growing perception that intensive
aquaculture is a modern industry; this industry is becoming subject to increased
scrutiny by policy makers and the general public and is becoming increasingly
influenced by social attitudes that have an impact on regulations, marketing and
product ranges and acceptability (Beardmore and Porter, 2003; Lee, 2003;
