Growth and Reproduction of Hawaiian Kala, Naso unicornis.
FINAL REPORT Prepared for Fisheries Local Action Strategy, Division of Aquatic Resources, Honolulu, Hawaii 96813.
Abstract:
Surgeonfishes (Acanthuridae) are a major component of Hawaiian reefs and as algal grazers, play an important role in structuring coral reef benthic communities. Declines in the overall catch and size of commercially targeted species have raised concerns about the long-term sustainability of local stocks. The bluespine unicornfish, Naso unicornis (or kala), is a large (up to 69 cm total length) surgeonfish that occurs in shallow habitats throughout the Indo-Pacific region and is extensively targeted by fishers. To support the sustainable management of Hawaiian kala we generated information on morphometric relationships and sex-specific size-at-maturity and growth rates.
