The island has a coastline of 322 km and is surrounded by a submarine continental shelf with 300 km 2 of fringing coral reef with a broad lagoon of 243 km 2 that protects much of the coastline in the north, east, south-west and north-west (Pichon 1971 ; Duvat 2009 ; Arndt and Fricke 2019 ; Bhagooli and Kaullysing 2019 ). The island was divided into four regions, north, east, south and west.…”

Small island developing states (SIDS) are highly dependent on coastal marine resources. Artisanal fishers in SIDS currently face multiple stressors related to global environmental change. Considering Mauritius (South Western Indian Ocean) as a case study, this paper characterizes artisanal fishers in SIDS and assesses their perception of global change using the Local Ecological Knowledge (LEK) approach. A semi-structured survey method was used to interview 247 fishers from all around the country. Artisanal fishers used multiple fishing areas and gears, with half of the fishers using Fish Aggregating Devices (FADs). Six main groups of fishers were identified according to their fishing strategies, which reflected different target species in their reported catches. The majority of fishers reported lower fish abundances and fewer species now compared to 10 to 15 years ago. All groups of fishers observed environmental change over the same period. Such ecological knowledge highlights the exposure of fishers to stressors induced by environmental change. The characterization of the groups of fishers and their fishing strategies will be useful to better evaluate adaptation strategies and support management measures to face global environmental change.

“…Visual census has many desirable advantages when species that are threatened, endangered, or sensitive to handling occur in the study area (Wilding et al 2001, Godinho and Lotufo 2010, Davis et al 2018, Arndt and Fricke 2019. However, the visual census can be impacted by structural complexity in the habitat of study, observer biases (the researcher's ability to identify and count individuals accurately), poor visibility, and fish response to the presence of the researcher (Brock 1982, Willis 2001, Galvan et al 2009, Irigoyen et al 2013, Bellwood et al 2020.…”

Numerous sampling methods have been applied to study intertidal rock pool fishes. There is limited information comparing the performance and suitability of such methods, which complicates comparisons between studies. We compared the performance of the bailing and visual census methods in 10 rock pools to quantify abundance, species richness, and structure of fish assemblages in rock pool intertidal systems considering fish residency affinities, rock pool volume, and substratum rugosity. Sampling was conducted 13 times across the complete set of 10 rock pools from June to December, 2018. Each of the pools was sampled with a visual census and then the bailing method. A sampling event was defined as the process of conducting both a visual and a bailing survey in a single rock pool. In total, 1,749 individuals of 14 species were detected using the bailing method, whereas 438 individuals of 8 species were recorded via visual census. The bailing method yielded higher abundance and species richness of resident, opportunist, and transient fish than the visual census. The detection of individuals and species showed a positive association with rock pool volume and negative association with substratum rugosity for both methods. In 32 sampling events, the bailing method detected fish correcting reports of fish absence (false negatives) recorded with the visual census. For the bailing method, resident fishes dominated the fish assemblage, whereas, for the visual census, resident and opportunist fishes contributed similarly to the community.

This paper is a checklist of the fishes that have been documented, through both published and unpublished sources, in marine and estuarine waters, and out 200 miles, from the United States-Canadian border on the Beaufort Sea to Cabo San Lucas, Mexico. A minimum of 241 families and 1,644 species are known within this range, including both native and nonnative species. For each of these species, we include maximum size, geographic and depth ranges, whether it is native or nonnative, as well as a brief mention of any taxonomic issues.
