The influence of bleeding on color, texture profile, and chemical quality of frozen pirarucu loins were investigated. The loins were obtained from eighteen (n=18) pirarucu carcasses from animals slaughtered by bleeding (BLE; n = 9) or without bleeding (NON-BLE; n = 9). The loins were sliced and assigned randomly for 1 and 12 months at -20ºC to analyze pH, water holding capacity, instrumental color, and texture profile BLE samples exhibited higher L* values (P < 0.05), whereas BLE and NON-BLE exhibited similar (P > 0.05) pH, a* values, b* values, and color stability at months 1 and 12. NON-BLE samples demonstrated greater (P < 0.05) hardness and chewiness at month 1, whereas similar (P > 0.05) springiness and cohesiveness were observed in BLE and NON-BLE samples at months 1 and 12. During storage, Both samples (BLE and NON-BLE) demonstrated a decrease (P < 0.05) in pH and water holding capacity; and an increase (P < 0.05) in lightness, hardness, and chewiness. Also, BLE and NON-BLE exhibited stable (P > 0.05) redness, yellowness, color stability, and cohesiveness. NON-BLE samples exhibited a decrease (P < 0.05) in springiness from the 1st to the 12th month of frozen storage. Bleeding positively influenced the quality of frozen pirarucu.

Climate change is expected to significantly change the availability and trade of fishery products due to changes in the distribution and productivity of marine and freshwater species. However, the high diversity in aquatic systems and their associated fisheries result in a mosaic of impacts and responses at the local scale which have not been comprehensively documented yet. This protocol has been designed to collect standardised local level data of local fishery changes and resulting adaptations of fishing communities around the world.

Urgent challenges posed by widespread degradation in tropical ecosystems with poor governance require new development pathways to reconcile biodiversity conservation and human welfare. Community-based conservation management has shown potential for integrating socio-economic needs with conservation goals in tropical environments; however, assessing the effectiveness of this approach is often held back by the lack of comprehensive ecological assessments. We conduct a robust ecological evaluation of the largest community-based conservation management initiative in the Brazilian Amazon over the last 40 years. We show that this programme has induced large-scale population recovery of the target giant South American turtle (Podocnemis expansa) and other freshwater turtles along a 1,500-km section of a major tributary of the Amazon River. Poaching activity on protected beaches was around 2% compared to 99% on unprotected beaches. We also find positive demographic co-benefits across a wide range of non-target vertebrate and invertebrate taxa. As a result, beaches protected by local communities represent islands of high biodiversity, while unprotected beaches remain ‘empty and silent’, showing the effectiveness of empowering local conservation action, particularly in countries experiencing shortages in financial and human resources.

Amazonian freshwater turtles are a key component of the Amazonian waterscape and an important resource for riverine communities. However, extensive exploitation combined with habitat alteration and climate change has endangered the giant South American river turtle (Podocnemis expansa) and the yellow-spotted river turtle (Podocnemis unifilis), two of the largest freshwater species in the region, reducing their numbers to only a fraction of pre-colonial levels. The survival of these species is therefore dependent on successful conservation efforts. For conservation to be successful, knowledge on where and when animals spend their time is necessary in order to successfully implement appropriate actions. However, little is known about the spatial ecology of Amazonian river turtles. To obtain information on spatio-temporal movement patterns and habitat use, 7 individuals of P. expansa and 3 P. unifilis were tracked in the central Juruá River region of the Brazilian Amazon using ARGOS satellite transmitters from 2011 to 2016. Space-use varied widely within and between the two species. P. expansa has a considerably larger home range than P. unifilis with a mean of 74,881 (±81,453 SD) hectares compared to 31,167 (±27,550 SD) ha, respectively. Both species show a high affinity to the main river, but P. expansa use the flooded forest and oxbow lakes to a larger degree than P. unifilis. After nesting at seasonally exposed beaches in August-September, P. unifilis moves into the surrounding flooded várzea forest as the water level starts to rise. P. expansa, nesting a month later, generally started moving at the end of November and early December. Upon leaving the nesting site, P. expansa leaves the river and moves into the forest until it returns when the water level drops rapidly in June. P. unifilis appears to move the furthest away from the river in November, towards oxbow lakes in the forest. Conservation of nesting beaches and the surrounding areas will continue to be important due to high site fidelity among the turtles. However, community-based protection along the river during seasonal movements and of flooded forests during high-water could improve survival and reproduction of P. expansa, within and outside protected areas, while the area around the nesting beach is a key habitat for P. unifilis.
