Declarations

: Fish were collected under the NOAA collecting permit no. NOAA-SRP-22-(2010 to 2020) and a scientific collecting permit issued to the NOAA Southwest Fisheries Science Center by the California Department of Fish and Wildlife (no. SC-13886). Protocols for the collection of fish were approved by the University of California Santa Cruz, Institutional Animal Care and Use Committee, IACUC (Alons1808).

: Our study improves the efficiency in the collection of important fecundity data for the viviparous Northeastern Pacific rockfishes by developing calibration curves to implement the autodiametric fecundity method for rosy rockfish (<i>Sebastes</i><i>rosaceus</i>), yellowtail rockfish (<i>S.</i><i>flavidus</i>), widow rockfish (<i>S.</i><i>entomelas</i>), vermilion rockfish (<i>S.</i><i>miniatus</i>), and chilipepper (<i>S.</i><i>goodei</i>). We show that calibration curves are species-specific, even in closely related species, due to the unique reproductive biology and ecology of each species. The adaptation of the autodiametric method will expedite fecundity quantification, which is important for estimating and monitoring stock reproductive potential in these economically and ecologically important species.
