Description

Since 1971 private persons, authorities and companies can send in otter carcasses to NINA who since then has an extended database and sample collection (e.g. muscle tissue, liver, kidney, heart samples). We collaborate with Artsdatabanken and Naturdata AS for exchange of other observations on dead otters (e.g. traffic kills, permission issued and legally shot, in fishnets drowned) to get a reliable and holistic overview of changes in population demographic parameters and population distribution over the years. The data is used for calculations of the national otter density index, updating the Norwegian Nature Index (otter as indicator species for fresh water ecosystems and for coastal ecosystems) and used in reporting to the Bern convention.

Data Records

The data in this occurrence 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 4,793 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.

Project Data

The Otter Registry is the official surveillance system for Eurasian otters in Norway where information on all reported dead otters are registered. The project is a continuation of the long-term data collection on dead otter material in Norway, which started in 1987.

Title Oterfallviltprosjektet
Funding The project receives yearly finances from the Norwegian Environment Agency (Miljødirektoratet) and additional financial support from several county authorities (statsforvaltere)

Sampling Methods

Study Extent Norway

Method step description:

  1. When carcasses or other otter remains reach NINA, NINA personnel take a variety of measures (e.g. sex, estimated age, weight, length, tooth layer identification of age, condition) and collect a number of tissue samples (e.g. muscle, liver, kidney, heart). We also collaborate with the national archive ‘Miljøprøvebanken’ and collect large samples of otter liver tissue for environmental toxicological analyses.
