|  Aquaculture has grown at 10% per year since the late 1980s compared to 3% for livestock for the same period and a quarter of the fish eaten in the world now comes from aquaculture which produced close to 40 million tonnes in 1998.Harvesting of wild aquatic resources and production of such in controlled environments (aquaculture) are done through the use of various technologies, encompassing vessels and their equipment, fishing gears and their operation and various types of enclosures to raise fish and other aquatic products. | | |  The technological development of and widespread use of synthetic fibres, hydraulic equipment for gear and fish handling, electronics for fish finding, satellitebased technology for navigation and communications, onboard conservation and increased use of outboard engines in small scale fisheries have all contributed to the major expansion of fisheries and aquaculture in recent decades. Technical advances have generally led to more efficient and economical fishing operations, reduction of the physical labour required per unit of output and improved accessibility to resources. | | | | The greater efficiency of fishing methods and of aquacultural production, in conditions where the sector's management has been ineffective, has sometimes led to overfishing and environmental degradation. This points to the need to develop more effective fisheries management frameworks together with safer and more environmentally friendly methods of production, for example, in developing selective fishing gear and in designing aquaculture systems that reduce their impact on external environments. | | | | |
