Thailand's 'Rewilding' Effort: Releasing Aquarium-Bred Leopard Sharks

Endangered Leopard Sharks

• 🦈 The Indo-Pacific leopard shark, once common in Thailand, is now endangered due to habitat degradation and accidental capture by fishermen.
• 💡 Conservationists are launching an effort to revive the species through a breeding program.

Star Project Thailand Initiative

• 🎯 The "Star Project Thailand" is a joint initiative focused on the augmentation and recovery of leopard shark populations.
• 📍 The project involves releasing aquarium-bred pups off Maiton Island, southeast of Phuket.
• 🌊 Leopard sharks play a crucial role in maintaining marine ecosystem balance by controlling prey populations.

Breeding and Acclimatization Process

• 🥚 Eggs from adult sharks are transferred to controlled tanks for daily monitoring of development and hatching.
• 📈 As sharks grow, they are moved to tanks suited for different life stages and then to the Phuket Marine Biological Center for behavioral conditioning and natural foraging development.
• 🏝️ A key step involves acclimatizing sharks in a sea pen for about 8 months, where they adjust to natural conditions, are fed daily, and their growth and health are recorded.

Measuring Program Success

• ✅ Last year, the program successfully reintroduced seven sharks.
• 📈 Beyond the number of releases, success is measured by the observed recovery of the leopard shark population, with divers seeing them daily and noting their breeding.
• 🐠 A healthy ocean ecosystem, including coral reefs and mangrove forests, is also a key indicator of success.
