Resident fin whales calving in the Gulf of California

Fin whales (Balaenoptera physalus) have resident populations in three different regions – including the Gulf of California. Daniela Bernot‐Simon, Lorena Viloria‐Gómora, Alejandro Gómez‐Gallardo and Jorge Urbán R. have now found evidence of the fin whale calving ground in the resident Californian fin whales. While numbers are recovering with around 100,000 individuals globally, fin whales are still listed as vulnerable by the IUCN Red List. With resident populations of animals showing greater susceptibility to human impacts knowing the calving grounds of these resident fin whales may prove key to protecting this population.

With the fin whales in the Gulf of California facing threats from ship-strikes, noise pollution, chemical pollution, run-off, entanglement in man-made debris and disturbance from industry knowing the reproductive behaviour and biology of the fin whales – as well as being able to protect their calving grounds will help keep this population healthy and growing.

The note “Evidence of a calving ground of the resident population of fin whales (Balaenoptera physalus) in the Gulf of California” by Daniela Bernot‐Simon, Lorena Viloria‐Gómora, Alejandro Gómez‐Gallardo and Jorge Urbán R., 17 April 2021 is published in Marine Mammal Science available through the Wiley Online Library.
