1 lip 2024 · The mass scaling exponents of SMR have been shown to be species-specific across a number of fish species and can either be stable or decrease across temperatures 51,52,53.
The world produces around 200 million tonnes of fish and seafood every year. This comes from a combination of wild fish catch and fish farming. In fact, the rapid growth of aquaculture over the last few decades means we now produce more seafood from fish farms than we do from fisheries.
18 kwi 2024 · Overall, we found by studying 54 fish populations around the world after a collapse, that the negative effect of fisheries exploitation on a population tended to be reduced whilst the effect of...
25 lis 2021 · Differences in fish community biomass across space are equally driven by both reductions in the total number of species and the disproportionate loss of larger-than-average species, which is...
19 sie 2020 · Our analyses uncovered a substantial increase in the functional richness of both ray-finned fishes (80% of LMEs) and cartilaginous species (sharks and rays) (75% of LMESs), in line with an increase in the taxonomic richness, extracted from these ecosystems.
10 paź 2018 · Based on occurrence data from all 17 453 species of percomorph fishes, regional richness was highest in freshwater (6584 species globally) and in the CIP (5659 species). Richness was moderate in the Central Pacific (3697) and Western Indian Oceans (2677), both flanking the CIP.
5 dni temu · Anthropogenic pressures are damaging tropical reefs, threatening their biodiversity and key contributions to both people’s well-being and nature itself. We analyzed 29 contributions from 1,237 tropical reef fish communities, revealing that, despite inherent trade-offs, these contributions can coexist locally. We distinguished fish community contributions primarily benefiting nature or people ...
