MBIS Soviet Trawl Fishery Data

This dataset comprises catch compositions and trawl locations from cruises of Russian fishery research vessels carried out in New Zealand waters between 1964 and 1987, containing 11547 demersal trawls from around New Zealand, Kermadec Islands, Antarctic coast and Tasman Sea. The data were obtained by exchange between the New Zealand Ministry of Fisheries (now Ministry for Primary Industries) and Soviet scientists in the mid 1990s.-Catch weights (kg) are added to the "occurrenceRemarks" field.-Sea temperature recorded by trawl headline sensors are added to the "dynamicProperties" field.Fisheries research trawls undertaken in New Zealand waters by Soviet research trawlers between the years 1964-1987.Most records are from bottom trawls, but there are also records from midwater trawls and non-random tows (such as gear trials and target tows).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.Citation:  Ministry for Primary Industries (2014).
