| Description (full): | The project was a five year study into the effects of trawling on seabed communities in the inter-shoal and inter-reef areas in the Far Northern Section of the Great Barrier Reef. The study arose from a GBRMPA convened scientific Workshop in 1989 to address the effects of fishing in the Great Barrier Reef region. The Workshop recommended that an experimental study of the effects of trawling should be carried out, taking advantage of the area closed to trawling (Marine National Park B) in the Far Northern Section of the Great Barrier Reef Marine Park. CSIRO and QDPI agreed to undertake the study, which was funded by these organisations as well as GBRMPA, FRDC and AFMA. Following the recommendation of the Workshop, the study was sited in an area known as the Green Zone between about 11°15'S and 11°45'S that was closed to fishing in 1985 as well as in the areas immediately to the north and south of the Green Zone. The study had several components: 1. A collation and review of all known biological, oceanographic and fisheries information available on the study area. 2. A description of the study area. This included a survey of the sediments, epibenthos (animals living on the seabed), fish and prawns in the region. 3. Comparisons of the areas that are open to trawling with those that are closed to trawling. 4. A Before-After-Control-Impact (BACI design) manipulative experiment comparing areas that were subjected to the Impact of a single trawl coverage with untrawled Control areas. 5. A Repeat trawl experiment in which strips of seabed were trawled up to 13 times. 6. A description of the composition of prawn trawl bycatch and the fate of discards from prawn trawling and a study of the interactions between seabirds and discards. |
