Preliminary age-based life history characteristics of dogtooth tuna, Gymnosarda unicolor (Ruppell, 1838), in the Western Pacific Ocean.
Welch, D.J., Smith, A.K., Krusic-Golub, K., Erdmann, S. and Newman, S.J. (2021)
This seminal article, led by David Welch and C2O Fisheries, used an innovative research approach and collaborated with recreational spearfishers and a team of colleagues, to provide the only age-based estimates of life history characteristics for the iconic Dogtooth tuna. This popular sportfish is experiencing increasing targeting by fishers throughout its range in tropical and sub-tropical reefs, and the results and management recommendations of this article are timely and much needed. Despite their popularity and increased targeting, they experience very little or no restrictions on harvest. Based on the research results, the authors recommend a minimum size of capture of at least 80 cm total length, and suggest that spearfishers should adopt an even more conservative approach by only targeting fish 100cm or greater, in order to promote sustainability.
