How useful is underwater video as a fisheries assessment tool in freshwater? @BowmanJacob_ asked this question for his honours thesis, by comparing video against other ways of counting fish. Editor's Choice in TAFS: academic.oup.com/tafs/advanc…

How useful is underwater video as a fisheries assessment tool in temperate freshwater ecosystems?

ABSTRACTObjective. Remote underwater video (RUV) is a noninvasive survey technique that has long been used in marine ecosystems and is now gaining interest

Are you new to CTmax tests (or CTmin)? Are you experienced, but unsure on what to report in your Methods? Do you think there any other factors at play? 🤔 Then this practical guide is for you! It even includes a fillable table! 😎 Happy to see this out in @MethodsEcolEvol
Graham Raby@graham_raby19 Aug 2025
Now published in @MethodsEcolEvol, a practical how-to guide to running CTmax experiments. Should be worth a read if you do or plan to do CTmax experiments. Includes a fillable table (inspired by @shaunkillen) for reporting your the details of your work. besjournals.onlinelibrary.wi…

The deadline to submit abstracts is approaching!!! ⏰ (March 7th) Consider submitting an abstract for a talk or poster in our session (A14) if you study the vulnerability of early life stages to environmental stressors! 🐣 The early bird registration deadline is May 16th.
Jeremy de Bonville@ichthyolojay18 Feb 2025
Hey you! Yes...you! You study early life stages? You like multiple taxa? You should consider presenting in our session: Vulnerability and adaptations of early life stages to environmental stressors (A14). 🚨Deadline : March 7th 🚨 See you at the #SEBCONFERENCE in Antwerp!✌️
