These squid are thought to migrate annually from Mexican waters into the CCS where they prey on many species, including several that support lucrative fisheries; however, swimming capabilities and features of long-distance horizontal migrations are not well understood. In the present study, adult Humboldt squid were tagged off central California with pop-up archival transmitting (PAT) tags (n = 5). All squid exhibited diel vertical migrations and swam south or offshore (west) during tag deployment (2.7 to 17.6 d). One squid swam south at least 34 km d−1 for >17 d and crossed into Mexican waters, which is the highest sustained velocity and the longest horizontal migration observed thus far for Humboldt squid. Results from a simple model to estimate the daily locations and velocities of each squid throughout the deployments suggest an average velocity of ~37 km d−1 and a maximum of ~50 km d−1. Additionally, the model suggests that one squid made a bidirectional movement (first north and then returning south) that was not evident from deployment and pop-up positions alone. This study provides insight into Humboldt squid migratory capabilities that are relevant to seasonal migrations and episodic range expansions, both of which are crucial to future interactions of this species with ecosystems and fisheries.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
