Marine Park Planning And Recreational Fishing: Is The Science Lost At Sea? Case Studies From Australia, Daryl Mcphee
Marine Park Planning And Recreational Fishing: Is The Science Lost At Sea? Case Studies From Australia, Daryl Mcphee
Daryl McPhee
“No take” marine parks are widely advocated and increasingly utilised as a tool aimed at protecting marine biodiversity, and they may also be used as a fisheries management tool. In Australia a national system of no-take marine parks is being established to protect marine biodiversity. The creation of this network of no-take marine parks that exclude the public from recreational fishing in large areas of the ocean is extremely contentious. Nearly one quarter of the Australian population goes recreational fishing at least once a year, and it is a $2 billion industry. The motivations for, and aspirations of these recreational …

A large-scale, manipulative experiment was conducted to examine the extent and rate of recovery of meadows of the temperate Australian seagrass, Amphibolis griffithii to different light-reduction scenarios typical of dredging operations, and to identify potential indicators of recovery from light reduction stress. Shade cloth was used to mimic different intensities, durations and start times of light reduction, and then was removed to assess the recovery. The meadow could recover from 3 months of light stress (5–18% ambient) following 10 months re-exposure to ambient light, even when up to 72% of leaf biomass was lost, much faster recovery rates than has …
