A 5 mo. fishing survey of these lakes was made in 1928. The depth of L. Albert, not previously known in detail, is nowhere more than 47 m., this rift lake haying been apparently silted up by the large rivers, Semliki and Victoria Nile. A series of cuspate sand bars and forelands, due to wind and wave currents afford the only sheltered waters; they control the distribution of the shore fishes, and so of the native fishing population. L. Kioga is nearly all less than 3 m. deep, large areas being covered by papyrus or water-lilies. It is a dying remnant of a great lake which, during the 2nd pluvial period, connected with L. Victoria and covered tracts of land to the north and south. The Murchison Falls, between the lakes, divides the Victoria-Kioga fauna above from the Albert and lower Nile fauna below. The fishing survey collection adds largely to the fauna of each lake and emphasizes this distinction, only 5 fishes being common to both faunas. Four new sp. (2 Lates) are recorded from Albert, and 6 new sp. (3 Barbus) from Kioga. Native fishing methods are described, the most unique being that of certain Banyoro natives of L. Albert, who take advantage of a natural food chain (Haplochromis albertianus[long dash]Hydrocyon forskalyi[long dash]Lates albertianus) in hand-line fishing. The last species grows to 200 lbs. weight and long-line fishing for it, as already practiced in a primitive way by Jonam natives, should prove of economic value. European influence has as yet had little effect on the fishing. Factors controlling the distribution of population are, in order of importance:[long dash]Tsetse fly; presence of fish (dependent on shore formation); salt deposits; presence of game.
