Annual trends in catchability and fish stock assessments

open access: yesScientia Marina, 2003
A key assumption of many fish stock assessment models is that catchability is constant over time. We assume here that trends in catchability may occur through fishing power creeping. The tuning fleets, which are prone to fishing power development, may be

PIA : more accurate taxonomic assignment of metagenomic data demonstrated on sedaDNA from the North sea [PDF]

open access: yes, 2020
Assigning metagenomic reads to taxa presents significant challenges. Existing approaches address some issues, but are mostly limited to metabarcoding or optimized for microbial data. We present PIA (Phylogenetic Intersection Analysis): a taxonomic binner
