From the end of January, some
countries experienced some historical area-based CA records (prior to 2012) missing from the downloaded
exchange data. The problem is traced and fixed. It is advised that the Exchange
data from NS-IBTS and SWC-IBTS downloaded from DATRAS in January-May 2016
should be revised. Other data products were not affected. For more information, please
CPUE per length data products had data type 'int' in the values fields, which is now corrected to 'decimal' to better facilitate the values based on the Trawl Data Type C. All length-based data are updated accordingly.
The first submission of the Belgian BTS data is now in DATRAS. We hope to get the rest of the submissions soon.

There were found problems with some historical CatCatchWeight data that were reported not in grams, but in 100g or kg units. DATRAS team is collecting more detailed data to correct the erroneous entries.

We have published a new version of DATRAS FAQs in our documents section. The new document combines information for both data users and data submitters. If you have any commens or ideas, write to us.
DATRAS data products used to refer to the species codes as provided by the data submitters. In the light of changed reference system (ITIS TSN to WoRMS AphiaIDs), and constantly changing valid species names, DATRAS has now an extra column Valid_Aphia in the exchange data, mapping the submitted code to the presently valid code in WoRMS. Similarly, the species codes in other DATRAS data products refer to the valid species codes instead of the reported ones.
In order to align with SeaDataNet vessel vocabulary, DATRAS ship codes are being mapped to the SeaDataNet ship codes. As a part of ship reference task, DATRAS BITS data starting from 2004 changed ship reference code from SOL to SOL2.
The workshop targeting DATRAS data products and their improvement is planned to be held in Copenhagen at 7–10 October 2014. Find more information here, and contact the group chair to get involved.
DATRAS has launched web services provided by web API. Exchange data-based records (HH, HL, or CA) can be retireved by survey acronym, year, and quarter. Please let us know whether the new service meets your expectations, and if you have any further suggestions. Your feedback is very valuable to us.
DATRAS portal has got a new look. We've got rid of the old horizontal menu, and replaced it with some buttons and links on the right-hand side. Tell us your opinion whether it is hot or not.
At present DATRAS outliers procedure is not capable of handling submissions with semicolon as a field-separator. The procedure will eventually get improved, but for now all DASTRAS submitters are strongly adviced to use commas in their submissions.
Duplicates are discovered in DATRAS

information was available for download from DATRAS page from 17/01/2014
to 05/02/2014 and is now corrected.
DATRAS new home page is now live
Previously, DATRAS users faced problems with uploading decimals for fields TotalNo, SubFactor and HLNoatLngt to DATRAS. Even though it was allowed by format to upload 2 decimals for TotalNo, 4 decimals for SubFactor, and 1 decimal for HLNoatLngt, data in DATRAS were rounded or [cut off] to 0, 2, and 0 decimals correspondingly.
The problem is now fixed, and data can be submitted with up to 2 decimals for TotalNo, 4 decimals - SubFactor, and format was changed to 2 decimals for HLNoatLngt.
is now possible to upload files with date out of quarter. Instead of critical
error, the screening utility will display warning that can be accepted before
