摘要
this study describes the diversity and the subsistence fishing territoriality of traditional populations of a village ashaninka and two kaxinaw芍 living at the margins of breu river (brasil/peru). in general, samplings in the dwellings were carried out late in the afternoon, as the fishermen arrived in the village. the data were analysed in an exploratory way through the index of pondered dominance (id%), by analysis of variance and by a correspondence analysis in order to determine the associations of the fish species and the fishing spots between the villages of the indigenous reserve. the results of the analysis of variance demonstrated that differences exist between the fish diversities of the catches. however, post-hoc tests only detected differences in diversities between the hand fishhook and the other fishing gears (bow and arrow, castnets and rotenone tingui). although the use of bow and arrow resulted in a low capture (kg), this fishing strategy is associated with a high fishing diversity, in terms of number of species. these results demonstrate that there is no overlap in the frequency of the visits to the fishing spots between the ashaninka and kaxinaw芍 populations. this pattern is the same found for the correspondence analysis for the fish species, which describes the relationship between the deep pools environments exploited by the fishermen ashaninka and kaxinaw芍 of mourˋo. these ethnic populations still continue to maintain a strong cultural and cosmological tradition, with their territories defined in an informal way of the upper juru芍 area.
