Mean <i>Fenneropenaeus merguiensis</i> densites and skewness of density data.

Mean Fenneropenaeus merguiensis densities (per net) and skewness of density data for the downstream (a, b), midstream (c, d) and upstream (e, f) reaches of Alligator Creek estuary over the 2015–2016 wet season (trips 1 to 11; see trip dates in Fig 3). Mean densities (b, d, f) were calculated as raw arithmetic means, trimmed means (based on excluding a predetermined 5% of points from both ends of the data), Winsorized means (with Winsorizing applied to a predetermined 5% from both ends of the data), and log (x+1) transformed means. Skewness (a, c, e) was calculated using untransformed and log (x+1) transformed data.
