“…Many additional marine fish assessments have come from regional initiatives, further broadening the taxonomic coverage of the Red List (IUCN 2012). These include nearly all nearshore and many deep sea marine fishes from the Mediterranean (Abdul Malak et al 2011), Eastern Central Pacific (Polidoro et al 2012), Western Central Atlantic and Gulf of Mexico (Linardich et al 2019;Strongin et al 2020), Oceania (Pippard et al 2017), European waters (Fernandes et al 2017, Eastern Central Atlantic (Polidoro et al 2017), and Persian Gulf (Buchanan et al 2019).…”

Global biodiversitytargets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of entire species groups over time by monitoring changes in categories assigned to species. Here, we calculate this index for the world’s fishes in 2010, using a sampled approach to the RLI based on a randomly selected sample of 1,500 species, and also present RLI splits for freshwater and marine systems separately. We further compare specific traits of a worldwide fish list to our sample to assess its representativeness. Overall, 15.1% of species in the sample were estimated to be threatened with extinction, resulting in a sampled RLI of 0.914 for all species, 0.968 in marine and 0.862 in freshwater ecosystems. Our sample showed fishing as the principal threat for marine species, and pollution by agricultural and forestry effluents for freshwater fishes. The sampled list provides a robust representation for tracking trends in the conservation status of the world’s fishes, including disaggregated sampled indices for marine and freshwater fish. Reassessment and backcasting of this index is urgent to check the achievement of the commitments proposed in global biodiversity targets.

“…La capacidad global de los arrecifes de coral para suministrar peces ha disminuido a la mitad desde la década de los años 50 del siglo XX, un cambio que los factores de estrés climático han exacerbado (KM 9.2) 62,177,178,179,180 a través del blanqueamiento de corales, la acidificación, el SLR (Figura 30.4), los sedimentos terrestres y los contaminantes (Recuadro 30.3) 78,79,181,182 . La pesca a pequeña escala en arrecifes de coral suministra a las comunidades de las Islas del Pacífico una parte sustancial (en algunos casos entre el 50 % y el 90 %) de sus proteínas alimentarias e importantes micronutrientes 82,172,177,183,184,185,186 .…”

“…Coastal island ecosystems are diverse and include many types of habitats such as seagrass meadows, kelp forests, rocky shores, coral reefs, and sandy beaches [1,15,16]. Due to their diverse physical settings, topography, and geologies, coastal islands provide a rich array of marine habitats for the organisms that inhabit them [1,17,18]. In the environments of small-scale islands, terrestrial factors, such as freshwater discharges, exert a greater influence, with significant seasonal variability, than open ocean factors such as oceanic currents [13,16,19].…”

Coastal habitats are crucial for supporting ecological processes and serve as vital ecosystems for diverse fish species, providing essential functions such as feeding, nursery provision, and reproductive habitats. Fish communities are ecologically important components of coastal ecosystems and are affected by multiple environmental factors. Despite their importance, determining the effects of environmental factors on seasonal variations in fish species diversity and community dynamics remains a challenge. The advent of environmental DNA (eDNA) technology, an environmentally conscious approach, has resulted in considerable advancements in recent years and has been progressively adopted for marine fish population monitoring. Here, we used environmental DNA metabarcoding to study seasonal variations in fish community structure on a coastal island, and we assessed the effects of environmental factors in structuring these communities. Our findings revealed a rich diversity of 72 fish species across 40 families and 23 orders in the seawater surrounding an island of the Seto Inland Sea (SIS), Western Japan. Notably, the composition of fish communities varied significantly between seasons, with seawater temperature, salinity, and dissolved inorganic phosphorus (DIP) concentration identified as important factors correlated with fish communities’ structures. In conclusion, our study provides useful information of fish diversity, and we suggest that eDNA is a valuable technique for monitoring fish diversity in coastal areas. These findings are crucial for ecological studies and the environmental monitoring of oceanic coastal environments.
