ECOLUMP – acoustic tagging of lumpfish

24 April 2024 – April has been an exciting and intense period for the ECOLUMP project. We are now entering the spring reproduction period for lumpfish. The field season started in Langfjorden in the municipality of Alta in Finnmark, Norway, where the team marked 20 female lumpfish with acoustic tags. The array has more than 50 hydrophones, which will be downloaded in the fall of 2024. We hope to get information on the spawning behavior, depth, time spent in the fjord, movements between egg batches, and mortality.
