Causes of admission of sea turtles in the Wildlife Recovery Centre of La Oliva in Fuerteventura

Abstract

The Canary Islands are among the areas of the world with the highest concentration of sea turtles, however, there are factors make the islands a critical habitat for sea turtles, with numerous specimens stranding annually due to various causes, predominantly human activities. This study focuses on the Wildlife Recovery Centre of La Oliva in Fuerteventura and aims to analyze the main reasons for sea turtle strandings from January 2021 to December 2023. The most prevalent species in the area is the Loggerhead turtle (Caretta caretta), which is classified as an endangered species by the World Conservation Union. This study highlights the significant role of human-induced threats, such as fishing gear and boat collisions, in these strandings. Data was collected using the "Búho" program, a computer application that tracks admissions, cancellations and discharges at the recovery center. This program enables efficient data management and reporting, providing a comprehensive database for analysis. The study identified the primary causes of turtle strandings, contributing to a better understanding of the threats faced by these endangered animals. Additionally, a clinical case study of a Loggerhead turtle admitted to the Estación Biológica de La Oliva is presented, illustrating the medical interventions and recovery processes involved. The findings underscore the importance of continued research and conservation efforts to protect sea turtles in the Canary Islands. By identifying the main causes of strandings, this study aims to inform and improve conservation strategies to mitigate these threats. Furthermore, the research highlights the crucial role of wildlife recovery centers and veterinary teams in the rehabilitation and conservation of endangered species, emphasizing the need for effective data collection and management systems to support these efforts. This study not only contributes to the scientific understanding of sea turtle strandings but also aims to enhance the protection and recovery of these vital marine species in the Canary Islands.
