Although officially created, the protected reserve of Ngiri remains virtual, existing only on paper, many reasons can explain this hypothesis: - The insufficient national regulations, at least at the time of the establishment of this protected reserve, which had the effect of not having any application at the local level. - Conflicts of administrative and community interest arising from the overlapping of different laws or measures. - The authorities’ lack of interest in safeguarding biodiversity or the priorities given to other aspects of environmental management (development of fishing). - The local situation too complicated due to various conflicts between fishermen and eco-guards. - The lack of qualified personnel, of means, in particular financial resources, to implement measures for the sustainable management of the reserve. - The lack of skills in assessing the state of the environment and planning management. - The poor definition of the limits of the protected reserve, thus reducing its interest for the fauna and flora. - The very significant human pressure on the outskirts and the lack of ecological corridors to connect the reserve. - The lack of economic valuation of the said reserve.

The biodiversity of the Congo Basin is a resource that must be well known and managed. Despite the strong pressure exerted on it, biodiversity still contains emblematic species that must be preserved. In addition to their biological importance, tropical forests remain essential for the riparian populations. Hence the need for rational and efficient management.We were interested in a seasonal catch assessment of endangered species fish. The results obtained during this research prove the failure to respect the capture of certain species of fish without taking into account the respect of the season (the calendar, the fishing zones as well as the biological maturity).This state of affairs sufficiently proves that the Ministry of Agriculture, Fisheries and Livestock as well as that of the Environment, Nature Conservation and Tourism through the various services do not apply the regulatory measures for conservation of halieutic diversity.
