A study has been conducted on the identification and inventory of kinds of fish species Synodontis and Distichodus captured in the Congo River Lualaba in its part in Kindu. The methodology was the collection of data on fish species and genera Synodontis Distichodus field and treatments. The study specimens were harvested in different Beach of the Congo River in its Lualaba part, where fish are sold. The individuals harvested were obtained by purchase from the fishermen who use the nets as the main catching gear. The identification was made by browsing the available literature (identification keys and previous works). The study revealed that 3 species of fish of the genus Synodontis and 2 species of the genus Distichodus have been inventoried. The results of the qualitative survey shows that the species Synodontis Synodontis budgetti for the genre dominates with 25.64%, followed by the species Distichodus sexfasciatus with 21.37%, with 20.51 and decorus Synodontis Synodontis pleurops with 17, 09%. The species Distichodus rostratus is the least represented with 15.39%. As for the quantitative inventory, our results reflect the Synodontis species pleurops and Distichodus rostratus are less represented in the sample is 17.09% and 15.39%. As for morphometric measurements and weight, species Synodontis budgetti is longer with 4307mm and has a high weight 1171G and species Distichodus rostratus is short with a length of 1777 mm and the species has Distichodus sexfasciatus weight up to all species with 151g.

A study was conducted at Lake Ndjale to identify the fish that inhabit this aquatic ecosystem. This study contributes on the one hand to the knowledge of the fish fauna and to preserve in order to consider the introduction of the interesting species in pisciculture to improve the nutritional state of the population and its income. We thought that Lake Ndjale would overflow a relatively diversified ichthyofauna that would be poorly or poorly known. At the end of this study, we obtained the following results: - The fish inventory covered a collection of 648 fish divided into 9 families, 11 genera and 12 species that 9 families and 11 genera of the fish were listed. The families of Cichlidae and Mormyridae each have two genera and each genus bears one species. The families of Hepsetidae, Bagridae, Citharinidae, Mochocidae, Distichodontidae and Notopteridae are single-species families with one species per genus; except the family of Alestidae which is also mono-genus but with two species. - The analysis of the relative index of fish communities in Lake Ndjale provides sufficient evidence that the Mochocidae family is the best represented. It has 508 specimens in all the samples ie 78.61% Synondotis, Chrysichthys nigrodigitatus (6.8%), Marcusenius sanagaensis (5.41%), Oreochromis niloticus (4.79%), Brycinus derheni (0.92%), Hemichromis fasciatus, Hepsetus odoe and Distochodu rostratus (0.61%), Gnathonemus peterssi, Xenomythus nigri and Citharinus latus are only 0.46%. Based on our results, our hypothesis is verified and confirmed.

The present work on « the contribution of agriculture in the economic recovery of the Maniema province from 2010 to 2012 ». The overall objective of this study is to measure the contribution of agricultural production in the recovery Economic development of the Province of Maniema. To achieve this goal, we have formulated our issues around the following questions: What is the contribution of Agriculture in the economic revival of Maniema? And what are the obstacles to the development of the agricultural sector in The Province of Maniema? In view of the concerns raised, we believe that agriculture would not have an impact on the economic recovery of Made of low production. Then we believe that this situation is due more particularly to the lack of several Financing of food security in the province (lack of continual supervision of agri-multipliers, lack of Phyto Sanitary product, climatic disturbance due to irrational deforestations, non-accessibility of several roads of Agricultural service disseminated in the 4 corners of the province of Maniema) and lack of project to raise culture Perennial (agricultural plantations). Indeed, we note that the growth rate of agricultural production in 2011 and 2012 have either reached the negative or dropped to worrying proportions. This drop in production has negatively influenced the ratio of production to population, which ratio determines the degree of satisfaction of the population's food needs by local production. It is noted that this ratio is minimal, which means that the agricultural production of Maniema has not been able to feed the whole population of Maniema. The province, to fill the deficit, proceeds with the importation of the food products thus causing a release of currency and a delay in the economic revival. So, under these conditions, agriculture in Maniema has not been a stimulating element of economic growth.
