Description

Transcription of gill-net events from Norwegian grey literature. The dataset covers gill-net test fishing results transcribed from grey literature (technical reports) throughout Norway.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 773 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Event (core)

Sampling Methods

Survey test fishing data. The gill-net method employed are indicated in the "samplingProtocol" field and consists of variations around the Jensen series of single mesh size gill-nets (Jensen, 1986, J.Fish.Biol, 28, 637-646; https://doi.org/10.1111/j.1095-8649.1986.tb05198.x). Either bottom or floating gillnets, or reduced series (). Exceptions are where the gill-net employed is unknown (samplingProtocol = survey_litterature or survey_gillnet_unknown_*).

Study Extent The dataset consists of a collection of sampling events from various sources. Sampling events consist of one night of test fishing unless otherwise noted. "samplingEffort" indicates the number of gill-nets employed and "sampleSizeValue" indicate the total area of gill-nets employed (in square meters).
