Prawn Trawling in the Great Barrier Reef

Keywords: regression, non-parametric regression.


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. In view of the large numbers and types of species captured in the survey the catch was summarized as a score, on a log weight scale, which combines information across species. Two such scores are available. The details of the survey, and a full analysis of the data, are in Poiner et al (1997).


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
