Descrição
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. This dataset is taken from the resulting fish communities database. These data have been used to show geographical and depth distributions of species from all research tows within the New Zealand EEZ since 2008.
Registros de Dados
Os dados deste recurso de ocorrência foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 495.600 registros.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Métodos de Amostragem
Most records are from random bottom trawls, but there are also records from midwater trawls, scampi trawls and non-random tows (such as gear trials and target tows).
| Área de Estudo | Fisheries research trawls since 1961 over the New Zealand EEZ area. |
|---|---|
| Controle de Qualidade | 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. |
Descrição dos passos do método:
- 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.
