Survey of the nocuité of the contraptions and techniques of artisanal fishing on the populations of navy turtles of the bay of Loango (Congo).

Chelonia marine turtle species preservation is one of the international community challenges through the world. In Congo-Brazzaville, the Renatura organization (ONG) is engage to the biodiversity marine turtle species protection. Among the five of seven marine turtle species encountered in the coast, Turtle lute (Dermochelys coriacea); Green turtle (Chelonia mydas); Olive turtle (Lepidochelys olivacea); Turtle caouanne (Caretta caretta) and Turtle overlapped (Eretmochelys imbricata). All these species of navy turtles well that protected by different international conventions, undergo several threats among which the nets and contraptions of traditional fishing constitute one of the main reasons of their decline. Indeed the accidental captures in the nets of the traditional fishers represent a serious threat for the navy turtles. This problem is delicate to manage because these holds don't depend directly on the will of the fishers. Indeed the turtles take themselves inauspiciously in the nets and entangle themselves of it while trying to clear itself/themselves of the net. To remedy this situation, Renatura Congo has, in 2005, initiated a program of liberation of the accidental captures of navy turtles in the nets of traditional fishing. About 1500 liberations are done annually by the agents of Renatura Congo. The liberation of these turtles doesn't constitute a long-term solution. Also, before the size of their accidental captures, it appeared to us necessary to bring our contribution in the survey of the nocuité of the contraptions and techniques of traditional fishing used to the bay of Loango in order to meter in evidence those that are more harmful. Such an objective reaches once, will allow us to improve these contraptions and techniques in order to reduce the risks of accidental captures while maintaining the level of the holds of fish and other aquatic organisms.

Assessment of the quantities of sold games in the market of a lumbering yard in the North Congo - Case of the market of Ngombé.

To Congo, as in many countries rich in forest resources as the dense forests or plantations, the installation of a forest industry in a given zone, often drag a continuous growth of the human populations. People massive arrival often poses especially some problems for their provision in essential goods in products of raising that are practically inexistent in these forest zones. Also, on the one hand, to satisfy their flesh-colored needs more and more crescents and, on the other hand to have a substantial income thanks to the merchandising of the game, these populations are forced to exploit the wild fauna massively. But, what are the quantities of games that are appropriated in these forest concessions and poured really on the markets of these forest yards?. The present survey values the quantities of games marketed on the market of Ngombé therefore, a forest concession in the North Congo. The specific objectives aim to establish the list of the soldest animal species on the one hand on the market of Ngombé and on the other hand, the list of the most dejected species by class of age, by sex and the list of the species the more valued. The adopted methodology is the one based on the active method of research participative: talks and direct questioning of fifteen (15) sellers through the cards of investigation. This survey took place from November 2009 to March 2010, either five (5) month of follow-up by the identified sellers. According to the results of this survey, the quantities of games marketed vary considerably according to the species. Otherwise, the adult animal species are hunted more that the young and the old, whereas the males he/it is more that the females. Finally, five (5) species out of the thirteen recorded are sold dearer than all other.
