In addition to scientific knowledge, Local Ecological Knowledge (LEK) can be useful for fishery management. This study aims to evaluate the knowledge of practitioners of snook fishing - recreational anglers and commercial fishers, in addition to fishing guides, about snooks Centropomus spp and its habitat. Semi-structured interviews were applied and results were analyzed using WebQDA and R statistical softwares to evaluate the prevalence of responses and multiple correlations. The interviewees were able to morphologically differentiate snook species and describe aspects of food behavior, habitat, migration and reproduction. Part of this knowledge was similar to what is reported in the scientific literature. LEK was evident in commercial fishers and fishing guides when compared to recreational anglers probably due to more extensive experience in the fishing activity. Through the interviewees' discourse, future scientific research demands were identified, such as understanding the factors that influence the growth of both species, migration between marine and brackish environments and the area of reproduction. This study demonstrated the advantages of using LEK to improve and promote adequate fisheries management.

Summary: Recreational fishing along the Brazilian coast has been poorly studied, with little effort made to estimate real catches. A study in the state of Sao Paulo collected samples to evaluate catches and found that the majority of species caught were below the size at first maturity, highlighting the necessity of improving recreational catches reports for better fisheries management and data collection.

Summary: Citizen science is an important tool for studying the spatial distribution of non-native species. A recent study in Brazil revealed the presence of Opsanus beta in several estuaries and shallow areas along the Brazilian coast. Through citizen science, researchers were able to track the dispersion of this species and identified ballast water and coastal shipping services as possible introduction routes.

The marine ornamental market in Brazil (Southwestern Atlantic) frequently trades prohibited and endangered species, and threatens the ecosystem role of cleaning mutualism

Laila M. Carvalho, Miguel Mies, Kelly Y. Inagaki, Eduardo G. Sanches, Marcelo R. Souza, Guilherme O. Longo, Acacio R. G. Tomas

Summary: This study investigates the potential ecological impacts of the marine aquarium trade on Brazilian reefs. Results show that the internal trade involves prohibited and endemic species, and illegal harvesting practices. Removal of the most traded cleaner fish species significantly disrupts ecological function. Hence, there is a need for reassessment of regulations and policies regarding the marine ornamental trade in Brazil.

Summary: This study investigated the distribution of diatoms in 324 estuaries on the Korean Peninsula from 2016 to 2018, with a focus on the ecological impact of artificial dams. The results highlighted the complex interactions between dams, land use, and diatom communities, providing important data for ecosystem management and biodiversity conservation. Understanding the consequences of artificial dams on diatom distribution is crucial for preserving estuarine health.

Potential challenges for the restoration of Biscayne Bay (Florida, USA) in the face of climate change effects revealed with predictive models

Vladimir J. Alarcon, Anna C. Linhoss, Christopher R. Kelble, Paul F. Mickle, Alexandra Fine, Enrique Montes

Summary: Estuaries and coastal areas are undergoing rapid changes due to climate change and sea level rise. This research presents a salinity transport model for Biscayne Bay and investigates the potential impacts of altered precipitation, increased salinity/temperature, and sea level rise on bay salinity. The findings suggest that current restoration plans may not be sufficient to maintain current salinity conditions, and management measures such as urban greening, artificial groundwater recharge, and water consumption reduction should be considered.

Spatiotemporal fishing effort simulations and restriction scenarios in Thermaikos Gulf, Greece (northeastern Mediterranean Sea)

Donna Dimarchopoulou, Ioannis Keramidas, Konstantinos Tsagarakis, Vasiliki Markantonatou, Ghassen Halouani, Athanassios C. Tsikliras

Summary: The study shows that spatiotemporal simulation modeling is an effective tool for investigating management options in ecosystem-based fisheries management. It demonstrates that fisheries restricted areas can help rebuild the biomass of exploited stocks, but their effectiveness depends on the size and location of the areas. The study also suggests that a parallel reduction in total fishing effort is necessary to achieve the highest benefits of protection.

Yard space allocation of container port based on dual cycle strategy

Caimao Tan, Tiantian Qin, Junliang He, Yu Wang, Hang Yu

Summary: This study addresses the storage space allocation problem of container yards based on the dual-cycle operation mode. A mixed integer programming model is established to optimize container transportation distance. The results show that dual-cycle operation can decrease transportation distance and the space allocation method based on it is more effective than traditional methods. The study also provides management insights for container ports and suggests effective solutions for bottleneck problems.

Summary: This study aims to identify and explore the information requirements at different stages of the decision-making process of coastal nature-based solutions (NbS). The study found substantial differences in information requirements across the decision-making stages, with values and indicators becoming more specific and concrete as the stages progressed. The study also suggests that future changes in the information required for decision-making on coastal NbS can be anticipated and prepared for.
