Andrew F. Johnson

Consultant and Director @ MarFishEco (US/UK)

I currently run a fisheries consulting business (MarFishEco) based between Seattle and London. Depending on the size of the project, I can be working alone or with a team of up to 5 other ecologists, economists and GIS experts. At present my work focuses on small-scale fisheries in the Gulf of California, supply chain productivity in fisheries in general, understanding the potential of blockchain and distributed ledger technology to help us solve many common problems in fisheries, and evaluating the potential for future economic investments in small-scale fisheries in the Caribbean. I’m interested in integrating fisheries ecology, economics, social science and business to better understand how fish populations, seafood markets, fishers and markets behave. I believe we need to harness technology and work in ambiguity whilst rapidly prototyping and testing ideas iteratively if we are to keep up with technological development and the speed at which problems in fisheries develop and change. My time is usually spent undertaking peer-review science, meeting with different fisheries stakeholders and funders, running workshops, writing consultancy documents and creating public media content. I have been fortunate enough to work in many different fisheries in Europe, Central and South America, and Southeast Asia. I'm not keen on long emails so if you ever fancy a chat, email me your contact details and I'll give you a call. Thanks!
