Fisheries for Greenland halibut are conducted by boat in open water during the summer. However, in winter, fishermen travel to fishing grounds on the sea ice using dog sleds, drill holes in the ice, and deploy longlines using metal plate kites. While the scale of deployment varies between boat and ice longlining, the movement of kites used in ice longlining and their effect on the deployment range of the line is not well understood. We conducted experiments using an accelerometer to determine the underwater movement of kites and their effect on the horizontal range of longline deployment. This is the first report describing specific operational information on longline fishing under sea ice, specifically on the effects of the kite on longline deployment. The kite is attached to the leading end of the mainline and deploys the longlines horizontally as it moves downward towards the sea floor. When the kite and mainline are dropped into the sea, the kite extends the line horizontally while shifting forward-facing long side, and forward-aligned short side. The motion resembles a fluttering action primarily influenced by the Reynolds number and moment of inertia. When the mainline is held, the kite descends in a circular motion. With repeated fishing operations and the passage of time, the kite's movement is expected to decrease in both range and speed due to the buoyancy and tension of the mainline. These kite movements suggest that the deployment range of longlines could extend several hundred meters. Therefore, it can be inferred that the impact of winter ice fishing on the Greenland halibut stock is relatively low due to the limited deployment range of the longline when using the kite.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107203"},"PeriodicalIF":2.2,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422063","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}

These lobsters have a complex life cycle with a lengthy pelagic phase followed by a lengthier benthic phase, with several habitat shifts in some species. Finding adequate habitats is complicated for these lobsters, as they interact with different prey, predators, and competitors in subsequent habitats. This paper provides an overview of the characteristics of spiny lobster benthic habitats, focusing on two species from the wider Caribbean region, <em>Panulirus argus</em> and <em>P. guttatus</em>. Tropical spiny lobsters are omnivorous; therefore, food is not as limiting a component of habitat as is shelter, on which their survival greatly depends. Indeed, lack of appropriate shelter may result in population bottlenecks. This observation underlies the use of artificial structures (such as “casitas”) to enhance lobster habitats for fisheries and conservation purposes. Pros and potential cons of habitat enhancement are also reviewed. The other side of the coin is habitat degradation. Throughout the wider Caribbean and elsewhere, climate change –mostly resulting from anthropogenic stressors– and coastal development are increasing coastal pollution and eutrophication, seagrass loss, algal blooms, habitat fragmentation, coral reef degradation, and marine diseases, changing the habitat landscapes with potentially dire effects for spiny lobster populations. Because of the different habitats used by these two species throughout their benthic lives, <em>P. guttatus</em> is likely to be more vulnerable to coral reef degradation and the settling postlarvae and early juveniles of <em>P. argus</em> to degradation of seagrass and shallow hard bottom communities. Conservation of appropriate habitats for target species should be considered an important aim of ecosystem-based fisheries management.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107193"},"PeriodicalIF":2.2,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142422062","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}

In the past decade, benthic recruitment of juvenile lobster has declined, even as egg production has increased, suggesting heightening levels of larval mortality. Recent correlative studies in the Gulf of Maine further suggest early-stage larval survival may be related to the supply and composition of planktonic foods. Despite these correlative studies and the economic importance of the species, relatively little is known about how larval lobster interacts with its prey in the pelagic environment. During these early developmental stages, lobster larvae undergo significant morphological changes which influence their ability to capture and handle prey. This study used a combination of laboratory-based feeding experiments and video recordings to examine changes in feeding behavior and ingestion rates between larval stages. Calculated Ivlev-type functional response curves were used to evaluate how larval ingestion rates vary with prey density and by larval stage on a suite of prey species. We observed dramatic stage-to-stage improvements in the capacity to pursue, capture, handle, and ingest specific prey, especially after the metamorphosis to the postlarval stage. The results highlight the vulnerability of the early life stages to low food densities. They also elucidate differences in the ability of specific prey taxa to evade predation by larval lobster. Quantifying the interactions between larval lobsters and their prey enhances our understanding of how this economically important species interacts with the pelagic food web, which fraction of available zooplankton represent viable food sources, and how lobster larvae may be impacted by altered prey availability associated with climate change.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107179"},"PeriodicalIF":2.2,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421532","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}

The use of inadequate ice and uninsulated containers was estimated to increase post-harvest losses of marine fish by 40 %, all else being equal. Earning members, inadequate storage, longer time attached to the net, delayed marketing, and tide pressure were statistically significant and positively correlated with post-harvest losses, whereas family members and fish finder were negatively associated with post-harvest losses.

These differences in the ability of individual fishers to catch fish, and create economic returns, can be assessed through the application of efficiency analysis. This paper provides an empirical examination of efficiency indicators in the South Australian Spencer Gulf and West Coast Prawn Fisheries. Applying data envelopment analysis (DEA) to a unique vessel-level dataset that includes both quantity and value information, we estimate measures of efficiency in these input-controlled fisheries where effort decisions are made in real-time using a participative management approach. We find that quantity and value-based efficiency measures are relatively high but that the variability of value-based measures is increasing. This increasing heterogeneity in value, despite the homogeneity in quantities, has potential implications for pressures on cooperative management going forwards as fishers pursue different business strategies. Comparing the measures of efficiency to direct measures of individual profit, we find a divergence: technical and cost measures of efficiency are more strongly positively related to short-run economic performance while revenue-efficiency is more strongly positively correlated with long-run economic performance, suggesting that different efficiency metrics may be required for short- and long-run monitoring.</div></div>","PeriodicalId":50443,"journal":{"name":"Fisheries Research","volume":"281 ","pages":"Article 107191"},"PeriodicalIF":2.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421614","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}

In this study, otolith shape analysis was used to evaluate the stock structure of dusky rockfish across five geographical subareas exhibiting ecological differences in the GOA and Bering Sea and Aleutian Islands (BSAI), where dusky rockfish are managed as two separate stocks. A combination of size and shape indices, wavelet, and elliptic Fourier descriptors were examined from left and right-side otoliths collected from these regions (<em>n</em> = 522). Individual variation existed across subareas. Wavelet and elliptic Fourier descriptors indicated that mean otolith shapes were partitioned between the two management regions but also showed a high degree of overlap among subareas. Classification accuracies of otoliths to their subarea of origin through linear discriminant analysis (LDA) were variable (6.3–73.5 % and 15.4–65.8 % correctly classified for the elliptic Fourier and wavelet analyses, respectively). The highest classification rates were found between the western GOA and eastern Aleutian Islands, contributing to the observed differences between management regions and providing some support for current management paradigms. Dusky rockfish exhibited low to moderate overall classification rates (43.9–52.2 %), suggesting minimal stock structure within Alaska waters.

Questionnaire-based fisher and TM surveys were administered nationwide from March 2021 to March 2023.

Designing ecosystem models for management purposes requires the identification of key interactions and environmental forcing that drive the dynamics of fish stocks. This can be a very challenging task given the complexity of interactions, which determine the evolution of marine ecosystems. To overcome this difficulty, this study proposes a statistical approach based on multivariate time series analysis to identify the main biotic and abiotic interactions using as a case study of a complex and exploited marine ecosystem, the Gulf of Lions (GOL) in the Mediterranean Sea. To do so, first, pairwise Granger causality tests were performed to detect and select the strongest interactions and drivers, then followed by Multivariate Auto-Regressive (MAR) modelling techniques to evaluate the relevance of the selected causal relationships in a multivariate system. The results led to the identification of three statistical interaction networks (SINs) of moderated complexity.

Within the DCF, member states collect and analyze data relevant to sustainable fisheries management. To evaluate the status of fisheries, it is necessary to categorize fishing fleets into fleet segments. However, the current DCF segmentation is primarily based on technical vessel parameters, such as vessel length and predominant fishing gear, which often do not accurately represent the fishing activities of the vessels. To address this, we developed an alternative fleet segmentation approach that provides a more realistic overview of fishing activities. This approach utilizes multivariate statistics and is coupled with machine learning techniques for automatization. Applying this approach to two decades of German fisheries data resulted in a data set with fewer segments compared to the DCF approach, which represented the actual fishing strategies more closely. The comparison of biological stock health indicators calculated for both the current and the novel segmentation schemes revealed that the current scheme often misses signs of segments relying on overexploited stocks. The machine learning technique applied showed high classification accuracy, with misclassifications being rare and only occurring in segments with overlapping catch composition. Since machine learning enables almost perfect allocation to the revised segments, we expect a successful implementation of this protocol for future fleet segmentation. This approach is highly suitable for data collection and analysis procedures and can serve as a standard tool.
