Recent surveys and interpretations of the ongoing publication of data on the world fishery including aquaculture production reveals that the capture fishery sector (for statistics see: http://www.fao.org/fi/trends/aqtrends/ aqtrend.asp) reveals sustained growth of the aquaculture sector and stasis in world fishery production. Presently the bulk of marine aquaculture production occurs in coastal areas in shallow ponds and sea cages. The opportunities exist for a sustainable aquaculture industry to move into more offshore environments with the appropriate vessel and infrastructure support and to move onto the land where sea water can be treated to maintain optimum conditions for fish with the virtual elimination of waste discharge being a top priority. In the longer term it is expected that the fishery will be managed for environmental sustainability (ecosystem fisheries management) while the consequent short fall in fish production for human consumption will be made up by a diverse aquaculture industry. The constraints include the supply of raw materials in the form of economically viable feed components for cultured fish that are not themselves derived from the capture fishery sector. The culture of organisms low in the marine food web may be one way to remove this constraint. The marine engineering industries have a clear role to play in the supply of foods based on marine organisms from both the capture fishery and aquaculture sectors. \ua9 2005: The Royal Institution of Naval Architects
