Abstract:

A review of topography in culture in Nigeria was reviewed to enable the fish culturists know the basic principles to design and build fishponds, reservoirs and small dams and use existing topographical maps. All physical features of fish farms depend directly on the site topography. The exact plan of the fish farm need be followed. Do this by ensuring the position to build each structure. Soil quality varies and depends on the topography of the area. Topographical method can be used for maps showing the different kinds of soil present in an area of land. In this part, integrated farming, using pumps, how to plan your fish farm considering its size and complexity, laying out ponds according to their use, laying out the access roads on your farm, laying out the canals on your farm , Level differences on your fish farm, If you are building a barrage pond, A pump might be necessary and living on your fish farm are considered. The topography measurements reviewed are height measurement, measurement of differences in height, methods for measurement of height differences, calculating differences in height, the line level, the flexible tube water level, the T bone level, the improved T - bone, the bamboo sighting level, the hand level, Contouring Masonís level, The A - frame level, The a frame and plumb line level, contouring with non-sighting levels, contouring with sighting level and graded lines of slope to enable the fish culturists know these basic principles to design and build fishponds, reservoirs and small dams and use existing topographical maps.
