The main objective of this research was to design a standard model to contribute to sustainable and rational management of fichery resources on the Lake Kivu.
To reach this goal , we went with the theory of American John Alden Knight who developed a method of calculation base on the influence of both the sun and sea waters ,that is the conjugation of efforts implemented by the moon and the sun on the Ear tans consequently on the phenomenon of swamps the impact of which on the production of fish is known.
Nonetheless, despite the undeniable success with revolutionary character in the field of fisheries. The theory presents two major gaps.
- It favours the natural attraction of the two heavenly bodies - sun and moon. The nature, not man, is the main element of fishing activity.
- It is not applicable in all countries as the phenomenon of variations in tides is virtually nonexistent un continental regions that are from the oceans such as the region bordering the Lake Kivu.
Also, in order to overcome the deficiencies of john Alden Knight’s theory, a new theory, PEFAAPAUPROEME Model has been developed through our work. It intends to place man, and not the nature, in the centre of fishing activities. Is demonstrates amongst other things the conjugated influence, though unequal , of four human factors , namely gillnets , agency for the protection of the ecosystem and fishermen , and in the end , the fisherman’s associations on the variation in change of fish production in the Bukavu basin, This lacustrine space il located to south of the lake Kivu.
