In the Malebo Pool, fishing has become a major source of income for many fishermen and fish sellers. This could be explained, among other things, by the lack of remunerative employment, the exponential growth of absolute poverty and the successive looting which destroyed production tools, thereby generating opportunistic fishermen who do not have the rule of art. However, we note that on the fishing sites of Kingabwa-Masina (Mungole) and Kinkole, exploitation is oriented towards gathering without real governance. 

The general objective of this study was to determine the impact of artisanal fishing on fish biodiversity. Among the specific objectives, it was a question of making an inventory of the fishing of the Malebo Pool (the organization of fishing) and of predicting the quantity of fish caught (Kg) at the Kinkole and Kingabwa-Masina sites.

We used a literature review to explore the subject in greater depth. In order to familiarize ourselves with our study environment, we carried out pre-surveys between the months of February and March 2023. Our sample consisted of 220 fishermen, including 110 per site. Thanks to the well-established survey questionnaire and sampling, we carried out the actual survey from May 15 to August 30, 2023 to collect the necessary data. We also collected data for sixty days on the weight and price of four species of fish (Distichodus sp, Labeo barbus sp, Synodontis sp. and Schilbe mystus). The semi-structured interviews were carried out with fishermen gathered in a “focus group” to allow us to obtain answers to some concerns. 

Our investigations have proven that free access to resources, the lack of fishing closures, training sessions for fishermen, monitoring of regulations regarding the exploitation of fish resources and above all, the use of gear and techniques Fishing destroyers are factors that lead to the disorganization of fishing. These factors, which encourage artisanal fishing, have a negative impact on fish biodiversity. These factors, associated with the high number of fishermen, seriously threaten these resources and undermine their potential due to the non-selective and non-regulatory nature of the fishing gear used, which presents a danger to the sustainability of these resources. 

Regarding the relationship between the weight and price of 4 species of fish, it has been shown that variations in the dependent variable (Price) are normally explained by the independent variable (Weight). In other words, when fishermen from the Kinkole and Kingabwa-Masina sites increase their catches by 1 kg, there will be an increase in prices of 10708.59 FC, 11320.43 FC, 4740.06 FC and 10708.59 FC respectively.
