Ghost Fishing Headquarters

Pascal van Erp

Pascal is a GUE trained technical diver with a strong preference for wreck diving. He made hundreds of dives all over the world, during these dives, he encountered lost- and abandoned fishing gear and the sad and severe consequences for the life under water. Since he is co-founder of a Dutch North Sea cleanup project in 2009 he became driven by the removal of lost gear in the North Sea. Based on his experience and specific vision on diving operations related to environmental issues, Pascal decided in 2012 to dedicate his diving exclusively to environmental protection and started the Ghost Fishing Foundation — an international non-profit executed by volunteer technical divers which initiates, supports and promotes lost fishing gear removal initiatives. Nowadays they run lost fishing gear survey and removal projects in the North Sea, Adriatic Sea, Aegean Sea, Mediterranean Sea, Caspian Sea, Pacific Ocean and Scapa Flow.

Cas Renooij

Cas is a diver since 1997 with an ever increasing interest in everything related to diving. Besides GUE technical, wreck and cave diving, he is keen to combine diving skills with environmental activities. He is an active participant in Project Baseline and has participated in projects in the most dived Dutch part of the North sea including remote areas like the Cleaver bank and Dogger bank. Removing nets from wrecks has been the main activity since 2007. Co founding Ghost Fishing is just another logical step forward in a journey that started after his first ventures in the underwater realm. Travelling the world from Bonaire to Micronesia, and from as far North as Iceland to the waters around Zanzibar, cold or warm, salt or fresh, open water or confined to wrecks and caves, even under the ice, Cas enjoys it all. Hardly any of his dives end without taking waste out of the water.

Case has been diving since 2007 and participated in all kinds of project like Project Baseline and Ghost Fishing. His greatest underwater passion is photography. Besides being a board member of the Ghost Fishing foundation, Case is responsible for the underwater footage of net-removal projects.
