          The Xisha Islands are composed of the Yongle Islands and the Xuande Islands in Hainan Province, China. It has one of the highest species diversity in the world and is also a typical oceanic distribution area of coral reefs globally. The ichthyofauna of the Xisha Islands were recorded by underwater visual census in May 2019 and July 2020. The survey data were combined with previous records of species into the checklist of the Xisha Islands presented herein. A total of 691 species, belonging to 24 orders and 97 families, was recorded. The major families were Labridae , Pomacentridae , Serranidae , Chaetodontidae , Hexanchidae , Lutjanidae , Scaridae , Gobiidae , Scorpaenidae and Carangidae . In this study, the Coral Fish iversity Index (CFDI) of six families ( Chaetodontidae , Pomacanthidae , Pomacentridae , Labridae , Scaridae and Acanthuridae ) was 229, indicating 756 coral fishes. In terms of the IUCN Red List, one species is Critically Endangered ( Glyphis gangeticus ), six species are Endangered ( Stegostoma fasciatum , Aetomylaeus maculatus , Aetomylaeus vespertilio , Epinephelus akaara , Cheilinusundulatus sp. and Xiphias gladius ), 16 species are Vulnerable, and 13 species are Near Threatened in the Xisha Archipelago, so conservation should be strengthened in this area in the future.

          New information

          One species is a new record for China ( Dischistodus pseudochrysopoecilus ) and 23 species are newly found in the Xisha Islands.

            Towards sustainability in world fisheries.

            Fisheries have rarely been 'sustainable'. Rather, fishing has induced serial depletions, long masked by improved technology, geographic expansion and exploitation of previously spurned species lower in the food web. With global catches declining since the late 1980s, continuation of present trends will lead to supply shortfall, for which aquaculture cannot be expected to compensate, and may well exacerbate. Reducing fishing capacity to appropriate levels will require strong reductions of subsidies. Zoning the oceans into unfished marine reserves and areas with limited levels of fishing effort would allow sustainable fisheries, based on resources embedded in functional, diverse ecosystems.
