Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast

open access: yesTransboundary and Emerging Diseases, Accepted Article., 2022
Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For

Assessment of errors in cetacean diet analysis: in vitro digestion of otoliths [PDF]

open access: yes, 1999
Research into the feeding habits of cetaceans has traditionally relied on examining samples taken from the digestive tracts of commercially caught or stranded and by-caught animals. This depends on the identification and measurement of hard parts such as

Annual, seasonal and spatial differences in the growth rate of Baltic cod larvae and early juveniles in relation to zooplankton biomass fluctuations in 2006-2014

open access: yesOceanological and Hydrobiological Studies, 2023
It is an acknowledged theory that a faster growth rate, determined by various environmental drivers, may boost the survival of larval and juvenile fish. In this study we examined the differences in the growth rate of larval and juvenile cod (age 2 – 136 ...
