SUMMARY:
Puffinus puffinus is an animal species that belongs to a migratory seabird, and migrates to the South Atlantic crossing the Hemisfere when in the non-reproductive stage, to spend the summer. The coastal zone of the brazillian northeastern region is considered a relevant spot for the migratory routes of seabirds, in special, the region named Potiguar Basin (Rio Grande do Norte and Ceará). This area is monitored by an Beach Monitoring Project (in portuguese PMP-BP) that records, annually, a lot of specimens stranded alive or dead. The aim of this work is to determine the spatial-temporal pattern of stranded Puffinus puffinus in the States of RN and Ceará, and identify the most frequent causes of death and perform a histopathological diagnosis for this specimen. Were used data from the PMP-BP collected in daily monitoring since 2011 to 2022. The animals founded alive were forwarded to the Rehabilitation Center of Marine Fauna from Projeto Cetáceos da Costa Branca from Estadual University of Rio Grande do Norte in the city of Areia Branca (RN) and the dead animals were conducted to the Laboratory of Marine Biota for necropsy procedures. In these necropsies were collected tissue samples of organs that presented macroscopic alterations, in addition to gonads for sexing. These collected material underwent histological processing at the Vertebrate Morphology Laboratory at Federal University of Rio Grande do Norte. Sixty-six (66) individuals were recorded during the monitored period, 14 males, 17 females and 35 with undetermined sex. Of these, 43 individuals were classified as adults and 12 as juveniles. The spatio-temporal distribution analysis indicated that 33 animals stranded in the State of CE and 33 in the State of RN, from September to February. Regarding the analysis of cause of death, it was detected that marine debris, mechanical trauma and oil contamination are among the categories with an anthropogenic relationship and account for approximately 33% of the causes of death. The other causes were related to exhaustion, sepsis and parasitosis. The interpretation and organization of necropsy reports combined with histological tissue analysis offer more complete answers within the field of conservation strategies in favor of these animals.
