Summary: This research focuses on the perspectives of CEOs in Icelandic fisheries industry on the obstacles in strategy implementation. It identifies internal and external obstacles not found in previous studies. These findings have theoretical implications in academia and can help policymakers and CEOs in understanding and addressing strategy implementation obstacles.

Summary: This article presents an individual-based model that simulates the spawning migration of Norwegian spring spawning herring and predicts their distribution and abundance in the Norwegian Sea. The model is validated against observation data and coupled with a physical oceanographic model. The model captures the observed characteristics of the spawning migration.

Summary: Micropolitan centers and regional towns are seen as drivers of economic growth in rural areas, but may also contribute to rural out-migration. In Iceland, the rural population is highly mobile, with long-term population growth mainly attributed to natural fertility. Residents of smaller communities in the north are not more likely to move than other rural residents, but are more likely to move to micropolitan Akureyri rather than the Reykjavik capital area.

Summary: Based on seismic surveys conducted in the Krysuvik geothermal area in SW-Iceland, it was observed that there is a complex migration of seismicity in the area. This suggests a connection between the migration of fluid and the upper-crust fracture system.

Summary: Species Distribution Models (SDMs) play a crucial role in fisheries management, and the integration of various data sources has become an attractive approach to improve model predictions. Integrated Species Distribution Models (ISDMs) have the ability to formally combine different types of data and account for scale proportional gear efficiencies. This study demonstrates the use of ISDMs to integrate information from afishery-independent trawl survey and a fishery-dependent trammel net observations, showing the sensitivity of model outputs to different weightings for the commercial data. The results are compared to ensemble modelling, highlighting the requirement for consistency in response variables and link functions across models.

Summary: This paper compares two machine learning approaches for extracting handwritten information in pre-printed historical tables and evaluates their performance on different types of data. The results show that the model based on Multilayer Perceptrons performs better on homogeneous documents, while the model based on Graph Neural Networks generalizes better on heterogeneous data.

Summary: Ecological niche models and species distribution models have been widely used in various studies. In recent years, these models have been applied to marine environmental issues, especially to improve the forecasting and capturing of fishery resources. This study provides a bibliometric analysis of articles related to the use of these models in marine fishery resources, presenting their characteristics and findings.

Summary: Spatial management in penaeid trawl fisheries is crucial in avoiding non-optimal size classes of target species. Through a case study on Eastern King Prawn, it was found that there is good connectivity between management areas and the fishery, benefitting New South Wales fishers by protecting small prawns and allowing larger ones to be harvested, while also contributing to the recruitment source in Queensland.

Summary: The commercially important Norwegian spring spawning herring is known for its extensive annual migrations and large shifts in migration patterns on a decadal timescale. This study analyzed the spatial distribution and feeding patterns of herring in the Nordic Seas from 1996 to 2020. The research found that younger herring age classes are typically found close to the Norwegian shelf, while older age classes display larger distribution variations.

Summary: The BIOICE program conducted between 1991 and 2004 in Icelandic waters collected a total of 12961 asteroid specimens, including 23 new species. The most abundant asteroids were found at depths of 100-200 m and 400-500 m, with the area south of the Greenland-Scotland Ridge being more species rich than north of the ridge. The nonmetric multidimensional scaling (NMDS) analysis showed strong correlations between abiotic factors such as depth, temperature, salinity, latitude, and longitude with species distribution.

Summary: This study examines the impact of gossip on out-migration intentions in small communities, particularly for women. The research suggests that the more gossip there is, the more likely individuals are to have migration intentions.

Summary: Research shows that juvenile Atlantic herring may use a time-compensated sun compass for orientation during their migration. Their swimming direction is still affected even when the sky is cloudy.
