High squid numbers in the Pacific Northwest linked to climate change

A new study, published in the journal Marine and Coastal Fisheries, has found that the rising amount of ocean heatwaves, triggered by climate change, has a direct effect on the population numbers of the squid species Doryteuthis opalescens which primarily was known to inhabit the warmer waters off Baja California.

According to the study, the population numbers of the species have significantly increased between 1998 and 2019 along the Pacific coast, with Washington seeing a 39-fold increase in squid populations and Oregon recording a 25-fold increase.

By examining fisheries-independent survey data collected by the National Marine Fisheries Service, the researchers were able to develop a spatiotemporal model that shows squid density changes from central California to northern Washington fro...
