Trawl data from the Great Barrier Reef


These data refer to a survey of the fauna on the sea bed lying between the coast of northern Queensland and the Great Barrier Reef. The sampling region covered a zone which was closed to commercial fishing, as well as neighbouring zones where fishing was permitted.

The variables are:

Zone an indicator for the closed (1) and open (0) zones
Year an indicator of 1992 (0) or 1993 (1)
Latitude latitude of the sampling position
Longitude longitude of the sampling position
Depth bottom depth
Score1 catch score 1
Score2 catch score 2

The details of the survey and an analysis of the data are provided by Poiner et al. (1997), The effects of prawn trawling in the far northern section of the Great Barrier Reef, CSIRO Division of Marine Research, Queensland Dept. of Primary Industries.
