Life History Information for Key Hawaii Coral Reef Fish Species - Data Collected in Coastal Waters of Hawaii from 2020-12-01 to 2023-05-23 (NCEI Accession 0303929)

Information to support Size Maturity and Spawning season for 7 species, including Fork length, Tail length, Mass, Gonad Mass, and GSI.

Size at maturity and spawning season were estimated for several species two Parupeneus goatfish species and five Kyphosid chub species, and the wet mount technique was compared to histology for microscopic assignment of maturity and oocyte stage. Fishes were collected from Oʻahu waters using spearfishing between 2020 and 2023, with a smaller number of samples coming from markets. Both freediving and closed circuit rebreather diving were used for sample collection. Macroscopic and microscopic methods of assigning maturity and reproductive stage were used for females, while a statistical assignment was used for males. L50 and L95 were successfully calculated for all species. Three of the kyphosid species can be distinguished only using x-rays so these three species were combined into a group for analysis.Wet mount maturity assignments were as accurate as histology when assigning maturity in female fish.
