Experts Call for More Realistic Stock Assessments The state of fish stocks in the world’s oceans is worse than previously thought. While overfishing has long been blamed on fisheries policies setting catch limits higher than scientific recommendations, a new study from four Australian research institutions reveals that even those scientific…
By Rainer Froese I thought the background story of our recent publication ‘New developments in the analysis of catch time series as the basis for fish stock assessments: The CMSY++ method‘ may be of interest to young scientists. It all started in 2011, when I was visiting Daniel Pauly at…
Thirty years and numerous upgrades since inception, FishBase is now the largest and most widely accessed global online information system on fish, providing unrestricted and quick access to key information –morphology and physiology, names, genetics and aquaculture, trophic ecology, reproduction and life-history traits, population dynamics, fish as food, fish pictures,…
In a five-day workshop organized by the EcoScope project at the Fisheries Research Institute (FRI) in Kavala, Greece from May 1st to May 5th of 2023, members of the Project Executive Board and International Advisory Board of EcoScope were joined by ten partners under Work Package 5: Assessing the Ecosystem…
Q-quatics’ partner, the Sea Around Us, has released a suite of free video tutorials for data users interested in learning how to perform stock assessments using the CMSY methodology. CMSY or the estimation of maximum sustainable yield from catch and resilience, is one of the novel stock assessment methods for…
Co-creator and editor of FishBase Dr Rainer Froese, known and recognized for his advance and computer-intensive stock assessment method CMSY, has recently published a new method for estimating the somatic growth of fishes and invertebrates from its maximum length combined with either its length or age at maturation or with…
Under the premise of finding out how much fish is left in our oceans since 1950, when industrial fishing operations began to spread to the world oceans, the Sea Around Us team together with the Sea Around Us – Indian Ocean, and the FishBase and SeaLifeBase teams assessed the status of over 2,500 fish and invertebrate populations exploited in the Exclusive Economic Zones of all maritime countries and the high seas.
The always buzzing Paris – which did it best to exhibit its usual accelerated rhythm even in pandemic times -, hosted on September 6-7, 2021, an equally dynamic FishBase and SeaLifeBase Symposium at the Grande Galerie de l’Évolution of the National Museum of Natural History. One presentation after the next,…
Results of using CMSY, advanced yet easy to use fish stock assessment model developed at GEOMAR by Froese et al., to reanalyze more than five centuries of cod fishing in Eastern Canada suggests that annual yields could have been sustained at high levels if authorities had allowed the stock of…
A new paper co-authored by Dr Rainer Froese (Senior Scientist at GEOMAR and Co-founder of FishBase), “Assessment of exploited fish species in the Lake Edward System, East Africa” applied data-poor methods developed at GEOMAR and produced several first-ever stock assessments. Summary: The unknown status of inland fish stocks hinders their sustainable…
