However, the high costs of structured surveys often limit the spatio-temporal coverage of the data available for modelling. To address this issue, we present a spatio-temporal modelling approach integrating structured survey data with unstructured presence-only data, which have greater spatio-temporal coverage than structured data, but are often disregarded in fisheries research. Data integration is achieved by generating pseudo-absences for the presence-only data and estimating spatially varying catchability for all data sources relative to the structured dataset. We consider a freshwater application, building longfin eel (<i>Anguilla dieffenbachii</i>, Anguillidae) spatio-temporal distribution models for the Taranaki region, New Zealand, and a marine application, building spatial density models for the vulnerable marine ecosystem indicator taxon Demospongiae in the South Pacific Ocean. We also conduct a simulation experiment to investigate the impacts of using pseudo-absences that do not reflect true absence patterns in our modelling framework. By integrating unstructured presence-only data, our approach improves the spatio-temporal coverage of the data available for modelling. Our applications provide results consistent with previous modelling studies but also offer new insights into the distribution and density patterns of longfin eel and Demospongiae. The simulation experiment found greater error and poorer uncertainty characterisation in models that mis-specified true absence patterns. We recommend assessing spatial structure in presence-only data and generating spatially structured pseudo-absences that match this structure. Our approach has many potential applications, such as providing enhanced information to assist fisheries in assessments and management.</p>","PeriodicalId":169,"journal":{"name":"Fish and Fisheries","volume":"26 4","pages":"699-716"},"PeriodicalIF":5.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/faf.12907","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the last 5 years, Fisheries and Oceans Canada (DFO), the federal institution responsible for managing Canada's fisheries, released policies and strategies intended to make fisheries management more inclusive of IKS. To measure progress in their implementation, we applied 13 semiquantitative indicators and qualitative analyses of IKS inclusivity to a sample of 78 public documents produced or co-produced by DFO to advise management decisions. Of these documents, ≈87% reported cases that did not meaningfully include Indigenous Peoples and their IKS, 9.0% reported cases in which Indigenous Peoples were included in some aspects of research but their IKS was not, ≈3% reported cases in which IKS contributed to objectives and elements of research design but the process privileged Western science over IKS, and only one document met a high standard for the pairing of IKS and Western science. The indicators that we developed in a Canadian context can be used, with locally appropriate revisions, to gauge the extent to which state governments in other countries are inclusive of IKS in fisheries management, thereby identifying shortcomings in law, policy, and practice and informing mitigation measures.

The findings reveal that the day when eels arrive at sea varies significantly with latitude, with northern eels arriving earlier. Migration speed differs between tidal and non-tidal habitats, suggesting that tidal currents facilitate faster movement. However, despite these patterns, we observed substantial variability in arrival at sea time and migration speed within water bodies, suggesting that the eel's migration phenology is considerably plastic.

Yet, it remains unclear how well the assumptions surrounding data-poor models derived from extensive cold-water fisheries fit the life histories and ecology of tropical coral-reef fishes. The present study compared the outcomes from length-based spawning potential ratio (LBSPR) models versus observed trends from a novel meta-analysis of nine fisheries-independent (FI) and fisheries-dependent (FD) data streams across Micronesia. Thirty target species that comprised over 70% of landings were examined across temporal and spatial fishing pressure gradients associated with FI and FD streams. Cluster analyses using normalised effect sizes from over 140 statistical tests grouped the stocks based on the magnitudes of decline in (proportional) biomass and size-structure. Interestingly, many species with the greatest declines had modelled SPR and fishing mortality outcomes that did not trigger management based on established thresholds. These inconsistencies were attributed to several factors: variable compensatory density dependence across species, rapid growth over short time periods for small-bodied species leading to hyper-sensitive switch points in SPR metrics, and unusually long lifespans that did not always correlate with body sizes or growth rates. The complexity of life histories appeared to limit the use of snapshot data-poor models for depicting relative stock status across species; however, data-poor outcomes through time for each species better aligned with FI and FD trends.

PAM provides a scalable approach for tracking fish species, community structures and population dynamics across diverse habitats, addressing many limitations of traditional monitoring techniques. By cataloguing species-specific acoustic signatures, PAM enables long-term monitoring of fish biodiversity, which is crucial for conservation in remote and dynamic aquatic environments.

We suggest that short term mixed-species shoals, that persist for minutes or hours, might form because lone individuals (or small groups) of one species might benefit from joining larger groups of heterospecifics to reduce predation risk. We carried out a literature survey, which revealed that mixed-species groups seldom contain equal numbers of species; rather one or two dominate, with others present as small minorities. Furthermore, we found that the proportion of minority species decreases as absolute shoal size increases. We suggest that although minority members of mixed-species groups might suffer costs associated with being odd, they might often still do better by grouping than if they remained alone. We term this ‘any port in a storm’. This explanation makes several predictions and assumptions, and we suggest approaches for testing these. For example, minority members should attempt to form single-species groups when the opportunity arises, and mixed species-groups should coincide with periods of heightened predation risk. Mixed-species groups may be influenced by the distribution of shelter, and further work is needed to disentangle the relative importance of aggregation versus social attraction in the formation of mixed-species-shoals. This account of mixed-species groups does not exclude other ecological functions, such as forager-guild formation, but may explain cases of short-term associations of minority species with numerically dominant species in fish shoals.

We reviewed 91 publications, which revealed a modest positive trend in research over time. Our findings suggest that the geographical distribution of life history traits may be more important than ecological variables in determining elasmobranch vulnerability to fishing. Furthermore, Rays and oviparous elasmobranchs generally exhibit higher finite rates of population growth (<i>λ</i>) compared to sharks and viviparous elasmobranchs, respectively. However, when correcting for phylogenetic relationships, these differences become statistically non-significant, highlighting the importance of accounting for phylogenetic non-independence when interpreting interspecific trends in demographic traits. A significant negative correlation between mean lambda values and IUCN status was found, indicating that species at greater risk of extinction have lower lambda values. Odontaspididae and Mobulidae are identified as the most vulnerable shark and ray families to fishing pressure, respectively. Our results suggest that elasmobranchs inhabiting lower latitudes and warmer temperatures are more vulnerable to fishing pressure. Methodological approaches have evolved, with a notable increase in the use of matrix models over time. Most elasmobranchs studied demographically are classified as least concern, particularly rays.

Model results suggest restoration efforts in inshore areas yield a 2%–3% increase in small-bodied forage fish and support a more robust pelagic food web. Restoration increases demersal fish abundance, and there is a suggestion that mangroves may promote this via a habitat mosaic effect.
