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. Monitoring for adaptive management should therefore include routine otolith collection and species classification to improve stock assessment and promote the development of appropriate management strategies for this important fishery in the northern Benguela.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107262"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To addrees this gap, we studied the crab species’ population dynamics, reproductive biology, and growth patterns across different Portuguese lagoons and estuaries on a monthly basis from 2019 to 2021. Surveys were performed in the Southern (Ria Formosa lagoon and Ria Alvor estuary), Central (Sado river/estuary) and Northern regions (Ria Aveiro estuary) of Portugal. Monthly biological data was used to analyse size-frequency distributions, sex ratios, spawning seasons, recruitment pulses, estimate carapace width at first maturaty and biological growth parameters. It was observed that spawning occurs almost year-round in all systems, with a peak in the colder months, between September and March. In the southern regions of the Portuguese coast, the spawning period starts earlier than in the central and northern systems, with a higher sex ratio recorded for females in all systems. The carapace width at which 50 % (CW₅₀) of individuals reach maturity is similar for both sexes, around 30 mm, a value below to the minimum landing size enforced in Portugal. The analysis of von Bertalanffy growth curves revealed a continuous recruitment with a peak during the colder months, with individuals reaching the size at maturation after six months. The fast growth and continuous recruitment leds to the existence of between four and six growth cohorts for both sexes across all system.

In this study we analysed seven years of trap and transport data (2016–2022), encompassing nearly 58,000 transported adult eels, to evaluate mortality during all steps of the trap and transport process (i.e., mortality in fishing gear, during holding, and during transport). We found that mortality rates were generally low for all steps, 0.2–1.4 % in the fishing gear, 0.6–2 % during holding, and 0.03–0.17 % during transport (percent per year on average), compared to expected mortality in turbines (estimated turbine mortality in the investigated area: 70% to &gt;99 %). The factors affecting mortality differed across the trap and transport steps, with year, season (day of year), temperature, and mortality in the previous step (i.e., indicative of general stress in the previous step, and/or poor condition) being the factors having an effect.

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. Our effort aims to provide insights for prioritizing key areas in conservation strategies and marine spatial planning. It also represents an important contribution towards adopting an ecosystem-based approach to fishery resource management in the Mediterranean basin.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107257"},"PeriodicalIF":2.2,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143133955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For comparison, the mechanical characteristics of twines without connections were also assessed. The results showed that the eye-splice and the sheet-bend connections of polypropylene twines are superior to the single-fixation and the double-fixation. Compared with the twines without connections, the breaking load of the connection twines is only reduced by 5 %. For nylon monofilament with a diameter exceeding 2 mm, the single-fixation connection is better than other forms, which reduces the load on the branch lines.
