Profile Image
Senior Lecturer


Ian has a background in European fisheries, having worked in Scotland before moving to New Zealand. He completed his PhD on scampi fisheries ecology in the early 1990s, before joining the FRS Marine Laboratory in Aberdeen. He has particular interests in scampi, and other shellfish fisheries, having been heavily involved in scampi assessment within the ICES system, and leading scampi research, survey and assessment activities for NIWA. He also has research experience investigating the effects of fishing on the seabed, and ecosystem indicators, and currently leads research in these areas. He has worked at NIWA since 2006, is a Principal Scientist in the Fisheries Centre, and leads the Fisheries Environmental Impacts Programme. Ian holds a co-appointment in the NIWA/Joint Graduate School in Coastal and Marine Science (1 day a week), through the Department of Statistics. The day he spends on campus is usually Friday, but sometimes varies, so to contact him the best option is email.

Exploring fishing power

Fishing power provides a measure of vessel efficiency, and can be used to explain why some vessels catch more than others. Commercial catch and fishing effort data are often used by fisheries scientists to estimate fish abundance indices (catch per unit effort), but often struggle to explain vessel effects identified. This project will examine a range of commercial fisheries catch data, to identify the factors that affect a vessel’s fishing power.


Available projects (Marine Science)

Starfish predation on scallops

Starfish are known predators of juvenile scallops, but absolute levels of predation, and the impacts this has at the population level are difficult to quantify. This project would combine aquarium studies examining prey handling and consumption / digestion rates with field collections examining starfish and scallop distributions, and the occurence (and size distribution) of scallops within starfish, to estimate population scale predation mortality levels. 

Project in conjunction with Dr James Williams (NIWA Auckland)
