Incidence of Odontocetes with Dorsal Fin Collapse in Maui Nui, Hawaii

Abstract: We examined the incidence of bent or collapsed dorsal fins of eight species of odontocetes observed in the nearshore waters of Maui Nui, Hawaii. Between 1995 and 2017, 1,312 distinctive individual odontocetes were photographically documented. Our photo-identification catalogs include 583 spinner dolphins (Stenella longirostris longirostris), 164 bottlenose dolphins (Tursiops truncatus), 132 short-finned pilot whales (Globicephala macrorhynchus), 253 pantropical spotted dolphins (Stenella attenuata), 82 false k… Show more

“…Van Bressem et al 2007): anatomical malformations and physical impacts may indicate interaction with vessels (e.g. Barcenas‐De la Cruz et al 2018, Stack et al 2019); skin lesions may evidence disease and/or water pollution (e.g. Reif et al 2009, Taylor et al 2021); anomalous pigmentation can indicate congenital conditions leading to individuals being more susceptible to environmental stressors (e.g.…”

“…The interaction between fishery activities and cetaceans has led to serious bycatch worldwide (Werner et al, 2015), raising an important issue on how to enhance the conservation on animals under serious threat. The victims include the pantropical spotted dolphins across the Pacific and Atlantic Oceans (Bradford and Lyman, 2015;Zhao et al, 2017;Stack et al, 2019;Carretta et al, 2020). The self-developed ADS system showed its potential to serve as a conservation tool for the pantropical spotted dolphins.…”

“…Stenella attenuata is primarily distributed in tropical and subtropical waters (Perrin and Hohn, 1994;Perrin, 2009). Interactions between fisheries and this species in and around Hawaiian waters have induced its serious entanglements with fishing gear (Bradford and Lyman, 2015;Stack et al, 2019;Carretta et al, 2020). Sixteen pantropical spotted dolphins were caught by accident during fishery activities in the Yellow Sea, China (Wu et al, 2015).…”
