摘要: Aquaculture has been practiced for some millennia. The speed and access of different transport modes in the spread cultured species, their pests, parasites, diseases associates, changed over this time. There now exists an overlap interlinking networks with further routes planned. Coupled environmental changes habitat alterations alien biota are presented opportunities to become more widely distributed. certainty responsible pathway arrival species is not always easily deduced unless imported directly. A scheme classifying levels proposed. itself consists cultivation intensities ranging from part all a life-history classified accordingly account. It inevitable that intended will be utilized world regions other biota, considered harmful, also transmitted. Nevertheless there codes practice such as those used by IMO ICES can reduce risks.
