The program relies on a core network of around 50 volunteer divers, who assist Shea with his mission to raise awareness about Hong Kong’s aquatic life. There are likely about 500 reef fish species in Hong Kong, but only about 460 have been identified so far; Shea and his team aim to find and document as many of the other overlooked as possible. Shea is also working on a photographic book about Hong Kong’s reef fish, which will be published in 2026.
