There are marked intra and inter-regional and country variations in a number of areas, such as production level, species composition, farming systems and producer profile. This presentation reviews patterns in global aquaculture development, including regional development, species cultivated, industry composition, research effort, trade and governance issues. As the sector further expands, intensifies and diversifies it should make efforts to address sustainability in a transparent manner.
