| This study determined the age and its correlation with biometric variables and reproductive indices of piapara Leporinus obtusidens caught at the Funil Reservoir. We caught 133 specimens between September 2006 and August 2007. Weight, total length, standard length, depth, height, head length and radius of the scales were measured. The sex was determined by macroscopic examination of gonads. The age of each fish was determined by analyzing the growth rings on the scales. Seasonal differences in biometric variables were tested using the NK test at 5%. The correlation of age and radius of the scales with the biometric variables and reproductive indices were analyzed using the SAEG software. Fish individuals ranging from 3 to 14 years of age were caught. In... |

| Fifty-six villages along the coast of the State of Paraíba, Brazil, were visited to determine and map the occurrence of Amazona amazonica (Linnaeus, 1766). Search was conducted with binoculars and the residents of each locality were interviewed using a questionnaire to obtain information about the occurrence and species´s biological data. Reports of recent and old occurrences, absence and feeding areas were registered. The food items mentioned were fruits, such as cashew, cashew nuts, palm oil, and agricultural products, such as corn. The reproductive period occurred between November and December. Breeding sites were mangrove areas and coconut trees, with nests being made in tree hollows. Questionnaires helped to elaborate a distribution map of the... |
