The selectivity of gear over time often evolves, either due to industry modifications or as the result of implemented management regulations. Such gear modifications can be utilised to better target desired sizes of commercial species or to mitigate against bycatch issues. Most of the European lobster, <em>Homarus gammarus,</em> fishers use parlour pots and often utilise an escape gap to allow undersized animals and bycatch to exit. To quantify the gear selectivity of commercial parlour pots with and without escape gaps we utilise v-notching, as a novel approach to mark and recapture. Across both gear types, a total of 933 lobsters were notched (all sizes and both sexes) and 316 were recaught (34 %). A generalised linear model framework was applied to estimate selectivity which considered the interaction between size and sex of lobsters. Gear with escape gaps showed that males exhibit a dome-shaped selectivity curve, with the peak at 100–109 mm carapace length (CL) whereas females were less catchable for all size categories except for the smallest size class of 80–89 mm CL. Gear without escape gaps predominantly selected for small animals of both sexes (&lt;90 mm) but, again, males exhibit a dome-shaped selectivity, with a peak at 80–89 mm (CL). This indicates that pots with escape gaps clearly select for legal-sized animals (&gt;90 mm) for both sexes. This novel use of v-notching in mark-release-recapture surveys demonstrates the potential to quantify the efficacy of the gear used in the fleet and shows the scientific benefit of utilising current fishery management measures and fisher collaboration.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"282 ","pages":"Article 107283"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143160414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyzed annual landings, fishing effort, and catch composition from 2000 to 2021 using mandatory landing reports and commercial data. Annual catches fluctuated, starting at 4 metric tons in 2000, peaking at 82 metric tons in 2011, and stabilizing at around 38 metric tons thereafter. Market demand, particularly from Asian markets between 2010 and 2016, influenced fishing dynamics, with a strong correlation between fishing effort and landings. Fishers exhibited adaptive strategies, alternating between mixed and non-mixed trips based on economic incentives. Analysis of size and sex composition of the catches revealed stable biological characteristics over time. Interviews with fishers revealed socio-economic challenges, including lack of health insurance, while highlighting the importance of fishing for household income. Informal management practices, such as selective harvesting and market-driven size preferences, have contributed to the stability of the fishery, although increased fishing effort raises concerns about sustainability.

Our results suggest that while the offshore cryptic biomass can contribute a large percentage of settlers to the Gulf, offshore biomass is unlikely to replenish highly exploited nearshore fishing grounds due to low likelihood of larval transport between offshore and nearshore habitats. Our results also indicate that high fishing pressure in nearshore areas, particularly by the recreational fishery, can change larval connectivity patterns.

The study examines the social dimensions by analysing connections among fishers and traders in diverse regions to identify trading variations and supply chain arrangements. Data from 75 puerulus fishers and 12 traders in Cisolok, Cilacap, Prigi, Popoh, and Lombok was collected through structured questionnaires, profiling livelihood conditions, operations, social networks, business arrangements, supply chains. The results highlight the significant impact of robust information sharing and agreements within local trade networks on the financial benefits generated through puerulus fishing for coastal fishers. Fishing and business arrangements are influenced by the characteristics of the local trade network, including geographic and economic resources. In summary, puerulus harvesting is important for coastal fishers, interconnected with trade relationships and networks.

This occurred in 2020 when the COVID-19 pandemic forced the cancellation of the research vessel-based 2020 eastern Bering Sea (EBS) acoustic-trawl survey, which has provided an estimate of euphausiid abundance and distribution since 2004. As a partial replacement for this lost effort, three uncrewed surface vehicles (USVs) were used to collect acoustic data. In contrast to the standard vessel-based survey, which provides 4-frequency acoustic data, the USVs collected acoustic data at only two frequencies. This presented a challenge given that four frequencies are currently used to identify euphausiids in this time series. Here, we first evaluated two methods to provide comparable euphausiid abundance estimates using fewer acoustic frequencies. We found that a random forest classifier was able to produce abundance estimates comparable to those obtained in the vessel-based time series. This method was then used to estimate euphausiid abundance and distribution from the 2020 USV survey. We additionally estimated the increase in survey uncertainty due to the use of the random forest classifier and changes in the acoustic instruments. Together, this allowed for the EBS euphausiid abundance time series to be extended with fewer acoustic frequencies.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"282 ","pages":"Article 107270"},"PeriodicalIF":2.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143161188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the peer- reviewed literature there is evidence of clustering around a few individual authors characterised by their large number of publications and their relatively frequent first authorship. These stock assessment networks are vulnerable because knowledge exchange may be constrained by repeat collaboration with the same central co-authors who are mostly from the same organisation, leading to siloing. However, this does not mean the stock assessments are necessarily wrong. We also find that network connectedness is highly influenced by a few papers that have a higher-than-average number of co-authors, many of which involve “one-off” authors.

However, establishing appropriate and cost-effective monitoring programmes that adequately capture the responses of fisheries to climate change have been elusive. The coastal waters of central and northern Namibia are a global hotspot of ocean warming, with several responses by fish impacting its coastal fisheries. One documented change is a poleward distributional shift of the west coast dusky kob, <em>Argyrosomus coronus</em> into Namibia, where it has begun to hybridize with the congeneric <em>A. inodorus.</em> With considerably different life histories, it is critical that managers can differentiate between these species and the hybrids to appropriately manage the most important recreational and commercial linefish species (bycatch and biomass) in Namibia. In this paper, we used otolith shape analysis, Linear Discriminant Analyses (LDA) to show that otolith shape can be used to distinguish between species and their putative hybrids, identified based on mitochondrial DNA and nuclear microsatellite data. A total of 342 individuals from northern and central Namibia (northern Benguela) between 18.5 and 22.7°S were genetically identified, with a subsample of 217 paired with otolith shape analysis. Otolith shape analyses with LDA and leave-one-out cross validation showed successful species identification at 96.3 % accuracy, and improved accuracy of hybrid identification compared to using body morphology by 50 %. The Fourier descriptors provided excellent classification accuracy for separating <em>A. coronus</em> from <em>A. inodorus</em> (and putative hybrids, but poorer classification accuracy for separating the hybrids from <em>A. inodorus</em> (4/8). We thus recommend using otolith shape analysis for distinguishing the two species but suggest that genetic identification is still required to monitor hybridization.

In fisheries context, the observations on species usually consist of data derived from survey campaigns, such as the Mediterranean International Bottom Trawl Surveys (MEDITS) programme. MEDITS survey foresees the use of a standardized protocol for data acquisition on demersal species, such as the blue and red shrimp <em>Aristeus antennatus</em> and the giant red shrimp <em>Aristaeomorpha foliacea</em>. These two species are recognized as highly valuable marked resources accounting for about 5 % of the trawl fishing income in the Mediterranean basin. Here, we developed a modeling framework for the analysis of the MEDITS data on those species. Within our modeling framework we aimed at detecting the existence of a divergence in the spatial patterns that could guide the definition of targeted management actions for those two valuable fishing resources. A Random Forest (RF) machine learning approach has been used to model both the occurrence (i.e., presence/absence) and the biomass index (kg/km²) of both species in four Geographical SubAreas (GSAs) located in the central part of the Mediterranean and the Ionian Sea. The RF showed high level of accuracy (i.e., K=0.83 and K=0.88, for <em>A. antennatus</em> and <em>A. foliacea</em>, respectively) in modeling species occurrence, and good level of performance (i.e., R²=0.63 and R²=0.74, respectively) in modeling their biomass index (kg/km²). The niche overlap and statistical analyses we performed on the models outputs revealed the existence of a significant divergence in the spatial patterns between these species. This provides crucial ecological knowledge for the definition of targeted (i.e., species-related) management actions. Afterwards, the models have been extrapolated at the spatial scale of the Mediterranean Sea based on an approach we defined, called <em>hyperspace</em>. The <em>hyperspace</em> approach, while showing technical and ecological soundness, was meant to guarantee the reliability of model predictions in unknown areas. It reduces the need for a proper interpretation of “what is beyond a predicted value”, offering a straightforward method for model extrapolation.
