Angling to Reach a Destination to Fish-Exploring the Land and Water Travel Dynamics of Recreational Fishers in Port Phillip Bay, Australia

Recreational fishing is a popular pastime and multibillion dollar industry in Australia, playing a key economic role, especially in regional areas. In the State of Victoria, Port Phillip Bay (PPB), bordered by Melbourne and its suburbs, is the largest of the State's marine recreational fisheries. At present, little is known about the spatial and temporal dimensions of angler travel from origins to destinations, and the applicability of such spatial knowledge in fisheries management. To address this lack of information we assessed spatiotemporal dynamics and patterns in fishing trips, based upon travel distances on land and water, to acquire insight into the spatial ranges over which anglers residing in various locations travel to fishing destinations in the environs of PPB. Data for each angler per fishing trip, from 6,035 boat-based creel surveys, collected at 20 boat ramps in PPB during a 10-year period from 2010 to 2019, were analyzed by applying geospatial modeling. Differences were observed in both land and water travel distance by region and popular target species, with anglers who launched from Bellarine region traveling further on land, and those who targeted snapper traveling further on water. It was also evident that most anglers resided within close proximity of PPB, often less than 50 km, although some anglers traveled long distances across the State to access fishing locations, particularly when targeting snapper. This work further highlights the importance of spatially explicit approaches to inform fisheries management by identifying users across different landscape and seascape scales, and out-of-region or State fishing trips, which may especially impact coastal communities and benefit local businesses.

Automated summary

Recreational fishing is a popular and economically important activity in Australia, with Port Phillip Bay in Victoria being a key marine recreational fishing area. Analyzing data from boat-based surveys over a 10-year period revealed differences in travel distances between regions and target species. Most anglers reside near PPB, but some travel long distances across the State, particularly when targeting snapper. This study highlights the importance of spatially explicit approaches in informing fisheries management and understanding angler travel patterns.
