Abstract As the urgency to evaluate impacts of climate change on marine ecosystems increases, there is a need develop robust projections and improve uptake ecosystem model outputs in policy planning. Standardizing input output data crucial step evaluating communicating results, but can be challenging when using models with diverse structures, assumptions, that address region‐specific issues. We developed an implementation framework workflow standardize fishing forcings used by regional contributing Fisheries Marine Ecosystem Model Intercomparison Project (FishMIP) facilitate comparative analyses across wide range regions, line FishMIP 3a protocol. applied our three case study areas‐models: Baltic Sea Mizer, Hawai'i‐based Longline fisheries therMizer, southern Benguela Atlantis models. then selected most steps illustrated their different types regions. Our adaptable models, from non‐spatially explicit spatially fully‐depth resolved include one or several fleets. This will development ensembles enhance future research applications, evaluation benchmarking, global‐to‐regional comparisons.

Temperature impacts on fish physiology and resource abundance lead to faster growth but smaller fish sizes and yields under warming

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(21), P. 6239 - 6253

Published: July 13, 2022

Resolving the combined effect of climate warming and exploitation in a food web context is key for predicting future biomass production, size-structure potential yields marine fishes. Previous studies based on mechanistic size-based models have found that bottom-up processes are important drivers fisheries yield changing climates. However, we know less about joint effects 'bottom-up' physiological temperature; how do temperature propagate from individual-level physiology through webs alter exploited species community? Here, assess species-resolved affected by both these pathways exploitation. We parameterize dynamic size spectrum model inspired offshore Baltic Sea web, investigate individual growth rates, size-structure, relative abundances warming. The magnitude projections regional coupled system RCA4-NEMO RCP 8.5 emission scenario, evaluate different scenarios dependence fish resource productivity. When accounting temperature-effects addition to basal productivity, projected size-at-age 2050 increases average all species, mainly young fish, compared without In contrast, decreases when affects dynamics only, decline largest fish. Faster rates due warming, however, not always translate larger yields, as lower carrying capacities with increasing tend result abundance hence spawning stock biomass. These results suggest understand global structure communities, direct metabolic indirect via resources must be accounted for.

Climate Change and Reproductive Biocomplexity in Fishes: Innovative Management Approaches towards Sustainability of Fisheries and Aquaculture

Water, Journal Year: 2023, Volume and Issue: 15(4), P. 725 - 725

Published: Feb. 12, 2023

The ongoing rapid climate change, combined with the disturbance of fish breeding grounds, may impact reproduction by endangering successful and survival, thus affect viable sustainability in aquaculture systems as well sea. In this study we focus on biocomplexity response to change. Further, propose adaptive strategies, including technological advancements, using a noninvasive non-lethal approach, outline an assisted nutrigenomics approach mitigating reproductive risks posed This was done effort monitor ensure that, livelihood, it provide useful source nutrition for our society.

Temperature‐Dependence Assumptions Drive Projected Responses of Diverse Size‐Based Food Webs to Warming

Earth s Future, Journal Year: 2024, Volume and Issue: 12(3)

Abstract Food web projections are critical for evaluating potential risks to ecosystems and fisheries under global warming. The temperature dependence of biological processes regional differences in food structure two important sources uncertainty variation climate forced fish communities, but we do not know their magnitude or relative contribution. Here systematically evaluated a range different assumptions about temperature‐dependence on rates, including size‐dependent effects, controlling intake, metabolism, non‐predation mortality fishes using species‐resolved size spectrum models that link individual‐level physiological population community dynamics. We simulated the effect warming size‐structured calibrated marine simplified trait‐based models. Higher intake warmed conditions increased total biomass, catches, mean body weight, these effects were offset by negative metabolism mortality, which combined resulted lower biomasses catches most webs. These enhanced when metabolic rates more than outcomes also sensitive dependency responses. Importantly, general patterns uniform across all webs—individual functional groups species within webs responded ways depending position its structure. Hence, caution is warranted generalizing because they mediated interactions. Uncertainty related ecological interactions will impact should be represented change projections.

Weight–Length Relationship Analysis Revealing the Impacts of Multiple Factors on Body Shape of Fish in China

Fishes, Journal Year: 2023, Volume and Issue: 8(5), P. 269 - 269

Published: May 19, 2023

The weight–length relationship (WLR) of fish is a crucial tool in biology research and has received extensive attention. However, growth influenced by many factors, the WLR also changes accordingly. Our aim was to investigate how body shape affected various factors analyzing existing parameters between length weight. We analyzed 198,354 specimens belonging 402 species 82 families China investigated change function their ecology. Herbivorous tended be shorter fatter than carnivorous fish, omnivorous fall somewhere between. This difference could due variations feeding habits availability food sources. Additionally, living lentic waters have compared those lotic waters. attributed differences swimming behavior these environments. Furthermore, our results showed that b value decreased as altitude increased, thinner longer lower oxygen temperature levels high-altitude Overall, study provides valuable insights into impact multiple on shape.

Individual variation in field metabolic rates of wild living fish have phenotypic and ontogenetic underpinnings: insights from stable isotope compositions of otoliths

Introduction Individual metabolism has been identified as a key variable for predicting responses of individuals and populations to climate change, particularly aquatic ectotherms such fishes. Predictions organism standard metabolic rate (SMR), the thermal sensitivity are typically based on allometric scaling rules respirometry-based measures respiratory potential under laboratory conditions. The relevance laboratory-based measurement theoretical predict performance free-ranging animals in complex natural settings questioned, but determining time averaged wild is challenging. Methods Here we draw stable isotope compositions aragonite fish otoliths estimate experienced temperature expressed field (FMR) simultaneously retrospectively at an individual level. We apply otolith FMR proxy population European plaice ( Pleuronectes platessa ) from North Sea during period rapid warming between 1980s mid-2000s, sampling tissue grown both juvenile adult stages.
