Little rays of hope were spread across the Plymouth Sound National Marine Park when an initiative to rear 44 baby rays (pups) came to its most natural conclusion and their release into the grassy seabeds of Plymouth Sound last month.

Developed in partnership with the Marine Biological Association (MBA), Shark Trust, and Devon Wildlife Trust, the project’s overarching aim was to raise awareness of the species of skates and rays that live in the waters of Plymouth Sound.

It saw members of the MBA team care for four adult female rays, which laid over 50 egg cases (often called ‘mermaid’s purses’) in the aquarium tanks. After egg-laying, the adult rays were returned to the sea, and the aquarium team incubated the egg cases, monitoring and filming the development of the embryos until the young rays hatched.

“After around four months, we successfully hatched over 50 baby rays, and this spring we prepared 39 of them for release into Plymouth Sound,” said Alix Harvey, aquarium manager at the MBA. 

“As well as making sure the pups were growing and feeding well, we also regularly photographed their spot patterns. These patterns are unique to each individual – a bit like fingerprints – and we’re hoping this approach could support a future citizen science project, enabling people to identify rays in the wild without needing to tag them.”

The Little Rays of Hope project is part of the Nature Boost Programme, which aims to create new and meaningful ways for people to experience and engage with Plymouth Sound. Spotted rays already exist in the Sound, the project is not about increasing ray populations or altering the ecosystem, but about giving people the chance to learn about these animals, see them up close, and understand more about their role in the marine environment.

Professor Willie Wilson, chief executive of the Marine Biological Association, said: “Projects like this are about inspiring people. The more connected people feel to marine life, the more likely they are to value and protect it.

“Sharing the journey of these young rays – from egg case to release – helps build a sense of ownership and care for the Sound.”

Plymouth Sound National Marine Park is a first of its kind in the UK which launched with a groundbreaking initiative to connect communities with the rich marine life of Plymouth Sound and support the restoration of nature within the park.

The Nature Boost Programme is part of the ambitious Horizons project funded by The National Lottery Heritage Fund. With £1 million invested over five years, the Nature Boost Programme is helping to embed marine engagement in the heart of Plymouth Sound – bringing science and community together to celebrate and explore the incredible marine life on the city’s doorstep.

Elaine Hayes, ceo of Plymouth Sound National Marine Park, said: “By connecting the public with these animals, we hope to inspire long-term interest and responsibility for our marine environment. Little Rays of Hope is a fantastic example of how we can engage people through storytelling, science, and hands-on experience.”
