Integrating eDNA and acoustic-trawl data to provide small pelagic biomass estimates for fish stock assessment Abstract. Accurate abundance estimates of fisheries resources are essential for sustainable fisheries management. In response to the growing need for devel

New paper by Cristina Claver (@azti.bsky.social), published in @icesmarine.bsky.social JMS.

We combine #eDNA and acoustic-trawl data in a Bayesian joint model to estimate biomass of the European anchovy in the Bay of Biscay.

From the potential of eDNA to operational use

Tracking the schools: a review of approaches to address knowledge gaps in the migratory ecology and habitat use of Canadian forage fishes - Reviews in Fish Biology and Fisheries Forage fishes play a vital role to marine ecosystems by linking lower trophic levels to top predators and serving as key economic and food resources for commercial and subsistence fisheries. Despite t...
