ABOUT DANA
Dana is Denmark's largest research vessel and DTU Aqua's primary vessel. Dana’s home port is Hirtshals in Northern Jutland.
The research vessel Dana is on the International Bottom Trawl Survey to collect data on the most important commercial fish species.
From 22 August to 9 September 2024, the research vessel Dana is participating in the International Bottom Trawl Survey (IBTS), which is coordinated by the International Council for the Exploration of the Sea (ICES).
The survey is conducted in spring and autumn every year. Countries fishing in Skagerrak and the North Sea (Denmark, France, Norway, Germany, Sweden, the Netherlands and UK England/Scotland) collect data on fish stocks in defined areas to cover a large area in total. The cruises also collect data on herring and sprat larvae in the 1st and 3rd quarter, respectively, as well as data on oceanographic conditions.
The dates of the cruise are subject to change.
Data is collected by short-term fishing at specific stations. Data includes e.g. fish age, length, weight, age and maturity, which are used to estimate abundance and biomass. In addition, hydrographic data is collected, such as temperature conditions, which can help explain the distribution of fish stocks.
Data from the countries' cruises is collated and processed in ICES. The results are turned into biological advice on the state of the fish stocks. This advice is targeted at the authorities, who use it as a basis when setting fishing quotas and other rules for fishing.
