The impacts evaluation of whale-watching vessels on Bryde's whales and implications for whale-watching regulations
摘要
Abstract
The Bryde's whale(Balaenoptera edeni edeni)around Weizhou Island,Beihai,Guangxi,is the only perma-nent large whale species in the coastal waters of China and represents the largest known nearshore population of Bryde's whale in the world.Since 2018,when Bryde's whales were first reported,the whale-watching tourism has greatly ex-panded.However,the lack of scientific whale-watching guidance and regulation on whale-watching tourism has likely negative impacts on Bryde's whales,highlighting the urgent need for impact assessments and scientific whale-watching regulations.Based on direct monitoring from 2022 to 2024,we found that 73.5％of vessels exhibited a range of prob-lematic behaviors,such as running directly at whales or honking or chasing them too closely.The average number of vessels around whales exceeded five,with a maximum of 24 vessels,and the average whale-watching time was(38.6±20.86)min.Vessels approaching Bryde's whale in parallel pattern caused the lowest whales' avoidance response(30.34％),whereas direct or turning approaching patterns(35.35％)caused the strongest reactions,with avoidance re-sponse exceeding 60.00％.When only 1-2 vessels were presented around whales,the neutrality response attained 66.72％,with the lowest proportion of avoidance response.When the distance between Bryde's whale and vessels was less than 100 m,avoidance response increased to 56.97％.As the distance increased,the proportion of avoidance re-sponse reduced,dropping to 10.64％when vessels were more than 300 m distant.Based on the results of this study and referring to 30 global whale-watching regulations,as well as communication with local authorities and practitioners,im-portant parameters of whale-watching practices were analyzed,providing a scientific basis for the effective protection of Bryde's whales around Weizhou Island.关键词
