Description:Climate change is impacting the abundance and distribution of marine resources. The consequences of these impacts are likely to alter trophic interactions between species within an ecosystem and affect fisheries opportunities for coastal communities. Market squid Doryteuthis opalescens comprise the largest fishery (by volume) in California, USA, and questions persist about whether the changing ocean conditions are leading to an increase in squid abun-dance in traditional fishing locations as well as marginal habitats in northern areas. To examine this potential phe- nomenon, we used fisheries-independent survey data collected by the National Marine Fisheries Service between 1998 and 2019 to develop a spatiotemporal model that estimates changes in the squid density from central California tonorthern Washington. We found a fivefold increase in the squid index of abundance across the entire spatial domain
