New Zealand fish and squid distributions from research bottom trawls 1964-2008

From 1997 to 2008, a research programme to determine if fish assemblages in the New Zealand region could be classified into clearly identifiable communities based on their associations with each other and with environmental features was undertaken. The programme resulted in the creation of the Fish Communities Database, from which this dataset was extracted. The dataset includes records from 1964 to 2008. These data have been used to show geographical and depth distributions of species from all research tows within the New Zealand EEZ since 2008.

Statement
The scientific names have been mapped to the World Register of Marine Species (WoRMS), using the online taxon match tool. All sampling locations have been plotted on a map to perform a visual check. The most important check would be to see if all sampling locations are (1) in the marine and/or brackish environment and (2) within the described sampling area. Only successful trawl records were selected. All "foul" shots are excluded as the net may have ripped and some species may have escaped on hauling. All species identification have been validated and outliers based on geographic and depth distributions have been checked. Catch weights (kg) are added to the "occurrenceRemarks" field. -Sea temperature recorded by trawl headline sensors are added to the "dynamicProperties" field.
