“…Romanelli (1995) cita valores de proteínas variando de 18,40 a 18,43% em carne de jacaré-do-pantanal e Moody et al (1980) reportam valores de 21,1% a 22,3%, nos quatro cortes estudados, em jacaré americano selvagem. Em carnes de animais selvagens são descritos médias de proteína de 19,56 a 22,8% (DAWOOD & ALKANHAL, 1995;LUZ et al, 2003;MARCHIORI, 2001;ZOMBORSZKY et al, 1996) em javalis, cervídeos, camelos e tartaruga da Amazônia. Em espécies domésticas (bovinos, ovinos, perus e frangos) são reportadas variações médias de 17,54 a 20,4% (NORKUS et al, 2001;PALEARI et al, 1998;SOUZA, 2001).…”

RESUMOForam utilizados 12 animais, sendo 06 (peso médio de 5,93 kg) oriundos de zoocriadouro (Z) autorizado pelo Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA), Estado do Mato Grosso, Brasil, e 06 (peso médio de 6,78 kg) oriundos do habitat natural (H), provenientes do município de Cáceres MT. As amostras foram coletadas dos músculos ílio-ischiocaudalis e occipito-cervicalis medialis, cauda e dorso, respectivamente. Nesses músculos foram determinados: umidade, extrato etéreo, proteína e cinzas. A extração de lipídeos foi conduzida com uso de clorofórmio/metanol (2:1). O colesterol foi determinado por colorimetria em espectrofotômetro. O corte da cauda dos jacarés Z apresentou médias de 74,50; 24,20; 0,83; 0,91% e o corte dorso 76,20; 23,68; 0,49 e 0,99% para umidade, proteína, extrato etéreo e cinzas, respectivamente. Nos animais H, as médias foram 72,29; 21,83; 5,43 e 1,09% na cauda e 76,70; 21,93; 0,54 e 1,25% no dorso (umidade, proteína, extrato etéreo e cinzas, respectivamente). As médias de colesterol nos animais Z foram de 48,82 e de 53,73 mg/100 g na cauda e dorso, respectivamente. Nos animais H, as médias foram de 37,05 mg/100 g na cauda e 40,61 mg/100 g no dorso. Assim, os jacarés de Z apresentaram carne mais magra, do que os jacarés H. E quando comparados os cortes, a cauda apresentou mais proteína e extrato etéreo, enquanto o dorso apresentou mais umidade, cinzas e colesterol.Termos para indexação: Animal silvestre, carne, composição centesimal. ABSTRACTThey were used 12 animals, 06 (with average weight of 5.93 kg) originating from captivity, authorized by Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis (IBAMA), Mato Grosso state, Brazil, and 06 (with average weight of 6.78 kg) originating from natural habitat, every animals coming from municipal district of Cáceres, Mato Grosso state, Brazil. The samples were collected of the muscles ílio-ischio-caudalis and occipito-cervicalis medialis, tail and back, respectively. In those muscles they were determined: moisture, ethereal extract, protein and ashes. The lipids extraction was driven with chloroform/methanol (2:1). The cholesterol was determined by colorimeter in spectrophotometer. The cut tail of the alligators originating from captivity presented averages of 74.50; 24.20; 0.83; 0.91% and the cut back 76.20; 23.68; 0.49 and 0.99% for moisture, protein, ethereal extract and ashes, respectively. In the animals originating from natural habitat, the averages were 72.29; 21.83; 5.43 and 1.09% in the tail and 76.70; 21.93; 0.54 and 1.25% in the back (moisture, protein, ethereal extract and ashes, respectively). The cholesterol averages in the animals originating from captivity were of 48.82 and of 53.73 mg/100 g -1 in the tail and back, respectively. In the animals originating from natural habitat the averages were of 37.05 mg/100 g -1 in the tail and 40.61 mg/100 g in the back. Thus, the alligators originating from captivity presented thinner meat, than the alligators originating from natural hab...

“…In Tapauá, per capita consumption of turtles is higher (15.9 g/person/day of turtle), but this value reflects the biomass of live animals. The yield of P. expansa ranges from 20.7% [42] to 50% of the weight of turtles without the hull [43]. …”

BackgroundConsumption of turtles by natives and settlers in the Amazon and Orinoco has been widely studied in scientific communities. Accepted cultural customs and the local dietary and monetary needs need to be taken into account in conservation programs, and when implementing federal laws related to consumption and fishing methods. This study was conducted around the Purus River, a region known for the consumption and illegal trade of turtles. The objective of this study was to quantify the illegal turtle trade in Tapauá and to understand its effect on the local economy.MethodsThis study was conducted in the municipality of Tapauá in the state of Amazonas, Brazil. To estimate turtle consumption, interviews were conducted over 2 consecutive years (2006 and 2007) in urban areas and isolated communities. The experimental design was randomized with respect to type of household. To study the turtle fishery and trade chain, we used snowball sampling methodology.ResultsDuring our study period, 100% of respondents reported consuming at least three species of turtles (Podocnemis spp.). Our estimates indicate that about 34 tons of animals are consumed annually in Tapauá along the margins of a major fishing river in the Amazon. At least five components related to the chain of commercialization of turtles on the Purus River are identified: Indigenous Apurinã and (2) residents of bordering villages (communities); (3) of local smugglers buy and sell turtles to the community in exchange for manufactured goods, and (4) regional smugglers buy in Tapauá, Lábrea, and Beruri to sell in Manaus and Manacapuru; Finally, (5) there are professional fishermen.ConclusionsWe quantify the full impact of turtle consumption and advocate the conservation of the region’s turtle populations. The Brazilian government should initiate a new turtle consumption management program which involves the opinions of consumers. With these measures the conservation of freshwater turtles in the Brazilian Amazon, is possible.

Many studies on mercury contamination in aquatic biota deal with the effect of consuming metal-contaminated organisms on human health. In this study, we examined the factors that cause mercury contamination in Podocnemis unifilis in the Xingu River Basin of Mato Grosso and Pará States, Brazil. We quantified by atomic absorption spectroscopy with cold vapor the total mercury (THg) content in the liver and muscle samples of 50 Podocnemis unifilis specimens collected from the basin. The liver and muscle samples contained 134.20 ± 119.30 ng g−1 THg and 24.86 ± 26.36 ng g−1 THg, respectively. Each chelonian or meal has, on average, 5.34× more Hg than the highest level established as acceptable. From the results it can be inferred that, given the weekly consumption of chelonians, the riverine and indigenous communities in the Xingu River Basin are at risk of chronic consumption of Hg in amounts beyond the acceptable limit. The potential high risk to the health of this population is evident; however, the risk classification needs to be further studied.
