Abstract:
Stranding, bycatch and rescue records provide an important source of information for studying the distribution and basic biological data of animals, especially for those species lacking systematic field survey. This paper collected the records of stranding, bycatch and rescue of the whale sharks (
Rhincodon typus) along the coast of Fujian Province from 2006 to 2019 and discussed preliminarily their temporal and spatial distributions in this area for proposing conservation recommendations. It showed that there were 30 cases of bycatch, stranding, and rescue of whale sharks along the coast of Fujian, including 10 cases of stranding, 18 cases of bycatch, and 2 cases of rescue. Fuzhou had the highest number of records of whale sharks, and most of them were around Pingtan Island which might be related to the rich biological resources caused by the upwelling in this area. 28 records (93.3%) occurred from June to October, indicating that summer and autumn may be the peak period of the whale shark activities along the coast of Fujian. In addition, most of the whale sharks recorded in this paper were juvenile individuals (77.3%), which preferred to gather in highly productive waters for sufficient food and made them prone to stranding or being caught by accidents. A large number of bycatches (60.0%) indicated that human activities, especially fishery, had a serious impact on whale sharks. Therefore, it suggested that a provincial or even national database of whale shark stranding and bycatch be established and further fishery management be tightened and standardized. The works of improving fishing gear, reducing the probability of catching whale sharks by accidents and strengthening publicity and education among the public, especially among fishermen, are necessarily preformed in order to have a better protection for this endangered species.
