Spatial and Temporal Distributions of Larval ’Ōpelu and Akule off West Hawaiʻi

August 01, 2023

Results identify a potential relationship of larval ʻōpelu occurrence with temperature and a concentrated akule spawning event in September 2016.

Understanding the essential fish habitats utilized by commercially important species has become a crucial component of Ecosystem-Based Fisheries Management (EBFM). Many larval and juvenile reef-associated and coastal pelagic fish populations are data-limited in the Hawaiian Islands. This study examines the spatial and temporal variability in larval distribution and abundance of ‘ōpelu (Decapterus macarellus) and akule (Selar crumenophthalmus) in West Hawaiʻi Island from 1997 to 2018
