Turtles are resources historically exploited by human populations in Amazonian ecosystems. Naturalists
report that Indians large numbers of animals in ponds in the villages for address consumption during the
high water period. Turtle nesting beaches, known locally as "tabuleiro de bicho-de-casco", are distributed
along of the Purus River. Abufari Beach (5 ° 22'12 "S and 63 ° 01'06" W), is located in the Abufari
Biological Reserve (RBA), in the municipality of Tapauá. This beach is one of the few remaining of from
this abundant period for the turtles in the Purus River. RBA belongs to the indirect use-category of
Conservation Units and has as its goal the research and conservation of fauna and flora. This study
evaluated the consumption of turtles, traditional ecological knowledge of fishermen on turtle ecology,
population structure and density of turtles in the Biological Reserve. We estimated a consumption of more
than 20,000 turtles of three species of Podocnemis (P.expansa, P. unifilis and P. sextuberculata) in 2007
in the urban area, and one trade of than $ 400,000 between 2006 and 2007. Based on the popular
knowledge were produce maps of distribution of
fishing area, hunting and harvest of forest wood and
non-timber and as areas of occurrence and movement patterns of turtles in the floodplain of the Purus
River. The maps and oral history showed that most of the 16 major nesting areas of P. expansa among
Abufari (RBA) and Sacado Santa Luzia (Sustainable Development Reserve Piagaçu Purus -RDSPP) have
been extinct, leaving only the Abufari and Tauamirim Beach ́s. Through experimental fisheries on sites
indicated on the maps we captured 3,377 turtles ( 2,390 captured with bag net in the channels Abufari and
Chapéu stream) and 987 turtles with seine nets on "boiador" of the Linda Vista at 2006 and 2007 years.
We estimated 2,833 females of P. expansa, 3,648 P. sextuberculata and 235 P. unifilis using the Abufari
Beach between August and November 2007. Total production for the three species on the Abufari beach
was estimated at 353,688 hatchling turtles. Traditional knowledge was efficient for describing movement
and factors that influence the movements of migration of turtles. Consolidation of this conservation policy
would be important for including all users of the resources or those are affected by its management and
the conservation of turtles, but it is necessary to change the rules of the Brazilian fauna. |
