Cuban Scientists' Efforts to Save Critically Endangered Manjuari Fish

The Critically Endangered Manjuari Fish

• 🐟 The manjuari fish, a species dating back over 140 million years, is critically endangered and found only in Cuba.
• ⚠️ Its decline is attributed to centuries of exploitation, habitat loss, and the introduction of invasive species.

Conservation Efforts in Zapata Swamp

• 🔬 Scientists at the Sienna Desapata National Park are leading a restoration effort to save the manjuari.
• 💡 A nearby hatchery is used to breed the fish and produce the necessary food for their survival before release.
• 🧬 The team collects specimens from the wild for quarantine and to incorporate them into the breeding stock.

Challenges and Progress

• 🚧 Challenges include isolation, shortages of supplies, and the fish's reclusive habits, making progress difficult to gauge.
• 📏 Scientists monitor the fish's physical condition through measurements like total length and weight to assess their evolution.
• 🌱 Despite difficulties, local fishermen report the presence of manjuari, indicating the reintroduction efforts may be successful.
• 🎯 The ultimate goal is to maintain and increase manjuari populations in Cuban waters for future generations.
