Tim Marsden is a fisheries biologist who specialises in Management and rehabilitation of freshwater fisheries with a particular focus on habitat access, maintenance and rehabilitation. Through the provision of fish passage at barriers and rehabilitation of degraded fish habitats we can maintain and improve the productivity of fisheries and ensure that our rivers, lakes and wetlands have a biodiverse fish community.

Over the past 30 years, Tim has I has focussed on fish communities of coastal rivers, where the access to freshwater habitats for a wide range of diadromous fish species is critical for population maintenance. Without access to good quality freshwater nursery and refuge habitats our freshwater, estuarine and inshore fisheries are negatively affected and biodiversity, as well as commercial and recreational fisheries suffer.
