Reproductive Biology of Bull Shark and Their Potential Use of Nursery Grounds
Project Leader
This project studies bull shark reproduction and nursery areas in Topolobampo, using science and community outreach to support conservation in the Gulf of California.
Understanding Bull Shark Reproduction and Habitat Use
This project explores the reproductive biology and habitat use of bull sharks (Carcharhinus leucas) around San Ignacio Farallón and the coastal region of Topolobampo, Sinaloa. Researchers aim to determine whether the area functions as a nursery ground, based on the frequent presence of juveniles and pregnant females. Using acoustic telemetry, photo identification, hormone analysis, and ultrasound imaging, the team will study shark movements, reproductive status, and site fidelity. These efforts will help map critical habitats and assess their importance for bull shark conservation in the Mexican Pacific.
PROJECT LEADER
Dr. Mauricio Hoyos
Dr. Mauricio Hoyos is the Director and Co-founder of Pelagios Kakunja in La Paz, Mexico. Since 1998, he has led shark research across several countries, focusing on nursery areas, reproduction, and migration. He sits on scientific committees for marine reserves in Mexico and actively contributes to conservation policy.
A passionate communicator, Mauricio has given around 300 talks, advised international documentaries, and earned multiple awards for his work. He’s a member of Mexico’s National System of Researchers and has authored over 85 scientific publications, a book, and several conservation manuals.
Community Engagement for Conservation
In addition to scientific research, the project includes a strong community engagement component. Educational programs in local schools aim to raise awareness about sharks and their role in marine ecosystems. By fostering a deeper connection between the public and bull sharks, the project encourages coexistence and support for marine conservation initiatives. This combined scientific and outreach approach contributes to the broader goal of protecting bull sharks and their habitats in a region facing increasing environmental pressures.
