DOI: 10.1002/ecog.07723

Abstract: In shelf ecosystems, benthic invertebrates facilitate nutrient recycling and the transfer of energy to higher trophic levels. However, large‐scale monitoring through direct sampling (e.g. using benthic grabs or bottom trawls) can be costly in terms… read more here.

DOI: 10.1016/j.aaf.2020.02.002

Abstract: Abstract Stratified random survey is commonly used to estimate abundance indices of fish populations in multispecies survey, providing reliable data for stock assessment and fisheries management. In some cases, however, the sample size is relatively… read more here.

Published in 2021 at "Ices Journal of Marine Science"

DOI: 10.1093/icesjms/fsab073

Abstract: A general spatio-temporal abundance index model is introduced and applied on a case study for North East Arctic cod in the Barents Sea. We demonstrate that the model can predict abundance indices by length and… read more here.
