Oceana Canada released its fifth annual Fishery Audit, a document that assesses the current state of Canada’s fisheries and fisheries management, tracks progress from 2017 to 2021 and provides recommendations to meet federal policy commitments to return wild fish populations to abundance.

Daniel Pauly’s biography now available in English

Two years after the release of Daniel Pauly: Un Océan de Combats, the English version of the biography of the Sea Around Us principal investigator is now available in bookstores.

Titled The Ocean’s Whistleblower: The Remarkable Life and Work of Daniel Pauly, the 342-page tome goes over Dr. Pauly’s scientific career as the whistleblower who alerted the public about the devastation caused to marine ecosystems by the global fishing industry.

Despite being the leading country when it comes to transparency, public accessibility, and free availability of fisheries data, the United States of America’s lack of international reporting of recreational catches and fish discarded at sea may hinder proper ecosystem-based management efforts, new research has found.

World Oceans Day 2021 – Using science to maintain healthy fish populations

To mark World Oceans Day 2021, the Sea Around Us team took on a challenge presented by NGO Mundus Maris and decided to think about one of the many problems our oceans are facing and reflect on the efforts being made to address the issue at hand.

This is how the above video came to be.

Since fisheries are at the centre of our work, we wanted to shed light on how reinterpretations of the Maximum Sustainable Yield model developed in 1954 by M.B. Schaefer are encouraging fishing practices that decimate fish populations.

Based on the paper “MSY needs no epitaph—but it was abused” by Daniel Pauly and Rainer Froese, and the paper “Fishery biomass trends of exploited fish populations in marine ecoregions, climatic zones and ocean basins” by Palomares et al., the video shows how the initial Schaefer model, which refers to the theoretical highest catch that a fish stock can support in the long-term given that environmental conditions do not change much, has been modified by fisheries scientists and managers to a point where it promotes overfishing.

But if kept in its original format and when combined with recently developed computer-intensive stock assessment methods, the Schaefer model has been identified – both in the literature and in the video – as a viable mechanism for effective ecosystem-based fisheries management.
