Résumé

Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial to anticipate challenges that are resulting from the current environmental alterations. In this review, we rely on the estimated physiological limits of six commercialised species of sea urchins (<em>Loxechinus albus, Mesocentrotus franciscanus, Paracentrotus lividus, Strongylocentrotus droebachiensis, Strongylocentrotus&nbsp; intermedius and Strongylocentrotus purpuratus</em>) to define the vulnerability (or resilience) of their populations facing ocean warming and acidification (OW&amp;A). Considering that coastal systems do not change uniformly and that the populations’ response to stressors varies depending on their origin, we investigate the effects of OW&amp;A by including studies that estimate future environmental mutations within their distribution areas. Crossreferencing 79 studies, we find that several sea urchin populations are potentially vulnerable to the predicted OW&amp;A as environmental conditions in certain regions are expected to shift beyond their estimated physiological limit of tolerance. Specifically, while upper thermal thresholds seem to be respected for <em>L. albus</em> along the SW American coast, <em>M. franciscanus </em>and <em>S. purpuratus</em> southern populations appear to be vulnerable in NW America. Moreover, as a result of the strong warming expected in the Arctic and sub-Arctic regions, the local productivity of <em>S. droebachiensis</em> is also potentially largely affected. Finally, populations of <em>S. intermedius</em> and <em>P. lividus </em>found in northern Japan and eastern Mediterranean respectively, are supposed to decline due to large environmental changes brought about by OW&amp;A. This review highlights the status and the potential of local adaptation of a number of sea urchin populations in response to changing environmental conditions, revealing possible future challenges for various local fishing industries.
