Estudo da comercialização da avifauna

Abstract

This work took place between January and June 1997, and was divided into two parts: one component referring to the field work carried out in the Dam Village area on the outskirts of the city of Chokwe, in Gaza province, and the second component included the use of Chikwirimiti company record books for data processing and survey of persons involved in marketing. The work deals with the study of the commercialization of avifauna, showing in detail how this activity is carried out in Mozambique. The study covers the specific composition of birds commercialized by companies licensed by the DNFFB (National Directorate of Forests and Wildlife) and in particular by the company Chikwirimiti which is a company dedicated to the capture and export of birds. In relation to this aspect, it was found that some bird species are more captured than others for commercialization. The study of the mortality rate of birds in all stages of commercialization was part of this work, from capture in the field, transport from capture sites or captivity to export and mainly during captivity, having observed that birds present rates of mortality during captivity. The relationship between the mortality rate and meteorological parameters was also part of this study, with a significant relationship being verified for some species. This study included the impact that catches have on the population of commercial species in areas heavily exploited by the company and the assessment of the size of these populations in these areas, concluding, according to the data, that the activity had a negative impact in the avifauna population in some areas and not in others. It ends with an approach to the economic return from the commercialization of the Chikwirimiti company in the national economy.
