Scientific survey report
Danish International Bottom Trawl Survey
2026
The Danish research vessels Dana and Havfisken are used for the
Danish participation in the Baltic International Trawl Survey (BITS),
which, since 1982, has had the purpose of annually monitoring cod and
other species.
Internationally, each nation surveys part of the area, with some
overlap in coverage and depth stratification, in a coordinated sampling
design. After agreement between countries a common standard trawl gear
and standard sampling procedures were implemented in 2000, resulting in
the consistent coverage of the western and central Baltic Sea.
The BITS is conducted twice a year in the first and fourth quarters
as a depth-stratified survey. The strata are based on sub-divisions and
depth layers. Each year the necessary stations are randomly selected
before the beginning of the international trawl surveys, from a list of
clear haul data. These stations are a stratified randomly selected
sub-sample of the possible trawl tracks.
The standard haul is a 30-minutes haul with a towing speed of 3
knots. Trawling only takes place during daylight, defined as the time
between 15 minutes past sunrise and 15 minutes before sunset.
All data can be found in the ICES DATRAS database (https://datras.ices.dk/Data_products/Download/Download_Data_public.aspx)
and details about the survey design and survey standardization before
2000 can be found in the ICES BITS manual (Anon. 2000).
Funding
The data collection is co-funded by the European Union through the European Maritime, Fisheries and Aquaculture Fund.
Period
Quarter 1
Activity
Here is shown a map with the survey activity for both vessls. The map shows both valid and invalid stations, a station can be deemed invalid if the haoul could not be conducted within the guilines of the survey manual
Trawl Stations
Each trawl stations consists a haul of 30 minutes where all the catch
documented, including litter. Biological samples to determine
e.g. stock, age matuity are taken from individual fish.
Bongo Stations
Each bongo stationsions in conducted with a set of three bongonets,
with net sizes 150, 300 and 500 micrometers. These are used for the
registartion of fishlarvey, plankton abundance and jelly fish.
CTD Stations
CTD (Conductivity - Temperature - Depth), are measured trough the
water column, and used to calculate e.g. the oxygen and salinity
content, key environmental variables for life in the ocean.
CTD Results
Here is shown a map the results of the CTD measurments at the bottom. The heatmap is made with linear interpolation between measurments, and can be seen as the general trend in the monment of the survey. If any CTD stations are not plotted data has not yet been precessed

Catch Overview
Below is a table with the total catche and catches for selected species, in wiegth and numbers. The numbers are in some instances calculated based on representative subsampling of some abundant species. The maps illustrates for biodiveity the number of different species cougt on each station, and for CPUE (catch per unit effort) the catch in numbers standadized to a unit effort of one hour of hauling.| Weight (kg) | Number | Min.
