There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. The latter has made up the largest and most significant share of all fishing. Open water covers 15.3 percent of Uganda's surface and comprises five major lakes (Lake Victoria, Lake Albert (Africa), Lake Kyoga, Lake Edward and Lake George (Uganda)which are the main sources of fish in the country. Lake victoria continues to be the most important water body in Uganda both in size and contribution to the total fish catch, followed by Lake Albert and Lake Kyoga.〔("2013 STATISTICAL ABSTRACT" ) ubos.org.Retrieved on October 29 2014.〕 Uganda's main sources of fish supply for both the domestic and export markets are the districts on Lake Victoria, particularly Mukono, Mpigi, Kalangala, Masaka and Luwero. Lake Kyoga, Albert, George and Edward districts are other major sources of fish. The major urban centres within the Lake Victoria belt, namely Kampala, Masaka, Jinja and Entebbe constitute the main domestic market centres for fresh fish. Although considerable fish supplies reach these market nuclei and most of the other district headquarters markets, inadequate supplies reach most of the rural markets.〔("TOWARDS AN APPROPIATE MANAGEMENT REGIME FOR THE FISHERIES RESOURCES OF UGANDA" ) unuftp.is. Retrieved on October 29 2014.〕 Primary production of fish is generally done on a relatively small-scale, as most of the fishing is carried out using small, wooden (plank-built) boats about six to eight meters in length propelled by oars or, in an increasing number of cases, a petrol engine fastened to the back of the boat. These simple boats are sufficient to carry fishermen to and from the fishing grounds with full loads of fish.〔("The political economy of the fisheries sector in Uganda: ruling elites, implementation costs and industry interests" ) subweb.diis.dk.Retrieved on October 30 2014.〕 ==History== Many centuries ago, fish production was mainly by a few fisherfolk communities living by the lakesides who bartered fish for other food commodities. Fishing activities were characterised by use of traditional gears such as spears, arrows, fish-pots, and the capture of fish by hand in shallow waters of lakes, rivers and swamps or fish poisoning with local herbs. However, these types of gears and methods still exist in minor lakes, the River Nile Basin and shallower areas of Lake Victoria. The fishing activity was relatively at a subsistence level. In mid-1950s, foreign traders introduced Japanese nylon gillnets which proved more effective in the fishery than the cotton, hemp and flax gillnets. Nylon gillnets gave higher catchability characteristics than any other gears mainly because of higher tensile strength, mesh-size constancy, resistance to abrasion and durability of the nylon fibre material. The introduction of new fish scpecies also boosted fish production. Fish production increased by six times in 30 years rising from 60,000 tons in 1961 to 245,000 tons in 1990 partly as a result of higher productivity of the lakes but also because of the increased catch effort. In 1983 when production was estimated at 78,000 tons p.a., potential production or Maximun sustainable yield (MSY) was estimated at 150,000 tons, yet by 1990 production had exceeded this level by 55,000 tons.〔("TOWARDS AN APPROPIATE MANAGEMENT REGIME FOR THE FISHERIES RESOURCES OF UGANDA" ) unuftp.is. Retrieved on October 29 2014.〕 In all areas outside the central Lake Kyoga region, fish production increased throughout the 1980s. The government supported several programs to augment fish production and processing. In 1987 a government-sponsored Integrated Fisheries Development Project established a boat construction and repair workshop at Jinja; a processing plant, several fish collecting centers, and fish marketing centers in several areas of Uganda. They also implemented the use of refrigerated insulated vehicles for transporting fish. China had managed the reconstruction of cold storage facilities in Kampala in the early 1980s. Soon after that, the government established the Sino-Uganda Fisheries Joint Venture Company to exploit fishing opportunities in Lake Victoria.〔(Uganda country study ).

In 1989 this organization warned against overfishing, especially in the Lake Kyoga region, where the combined result of improved security conditions and economic hardship was a 40- percent increase in commercial and domestic fishing activity. A second environmental concern in the fishing industry was the weed infestation that had arisen in lakes suffering from heavy pollution. In late 1989, officials were relatively unsuccessful in restricting the types and levels of pollutants introduced into the nation's numerous lakes.〔 A few fishers used explosives obtained from stone quarries to increase their catch, especially in the Victoria Nile region near Jinja. Using byproducts from beer manufacturing to lure fish into a feeding area, they detonated small packs of explosives that killed large numbers of fish and other aquatic life. Several people drowned in the frantic effort to collect dead fish that floated to the surface of the water. Environmental and health concerns led the government to outlaw this form of fishing, and local officials were seeking ways to ban the sale of fish caught in this manner. Both bans were difficult to enforce, however; fishing with dynamite continued in 1989 despite the widespread notoriety attached to this activity.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Fishing in Uganda」の詳細全文を読む スポンサード リンク
