Bob Sluka (Matt Brandon)Bob has been working in the field of marine conservation for twenty years. His focus has been on marine protected areas and the ecology of coral reef fish, as well as coral reef fisheries. After beginning with graduate work in Florida and the Caribbean, Bob spent ten years in South Asia, primarily India and the Maldive Islands. He was introduced to A Rocha on moving to the UK in 2006, and began volunteering with juniper restoration in the Chiltern Hills and marine research in Wales. In 2010 he helped to start marine conservation work at Mwamba, A Rocha Kenya’s Field Study Centre. He is based near Oxford, UK.

See further details of Bob’s research on our resources page; and reports, posters and scientific publications from our marine work in Kenya.

Why A Rocha?

It’s holistic. I can combine thorough research with theological reflection and on-the-ground conservation which blesses the local people.

What do you enjoy most?

Working with eager young scientists, helping them devise and develop their projects. And at the Kenya centre, conversations often explore the big questions about life, I can share my convictions and learn from others.

Is family life shaped by your passion for the sea?

We often head for the shore at weekends and holidays. When I took the family to A Rocha Kenya’s centre for two months, my three youngsters helped to write and design rockpool worksheets now being used by local primary children.

Tell us about a memorable underwater experience.

For a year I studied groupers off one of the remotest Maldive islands. The sun was setting, I was diving with local friends in a channel where probably no-one had dived before, and we let the current pull us through to a steep drop-off: suddenly, the ocean bed was thousands of feet below us, and up ahead was a group of spawning Napoleon Wrasse Cheilinus undulatus. They’re huge fish, longer than I am and endangered. It was a moment I’ll never forget.

In the Journal of the American Scientific Affiliation you called on the worldwide Christian community to respond to overfishing. What action would you most like to see?

I think that the major development organizations should consider how to serve coastal communities by getting involved in marine conservation. Coastal churches also need to raise awareness of the issues. We have resources which church leaders could use.

I couldn’t do my job without…

Too many unhealthy snacks!
