Summary: Historical information on cockle landings and local knowledge in the Ria de Aveiro remains incomplete, necessitating a study on recent changes in cockle fishing and fishers' satisfaction with the rules during the COVID-19 pandemic. The study revealed a downward trend in cockle stock over the past 60 years, as well as fishers' discontent with income and government support. Synergistic initiatives involving all stakeholders are essential for the sustainability of the cockle resource in the Iberian Peninsula.

Summary: This study proposes a deep FMNN (DFMNN) based on initialization and optimization operation to overcome the limitations of FMNN, including input order and overlap region problems. DFMNN improves performance by simultaneously designing hyperboxes and implementing deep optimization, outperforming several models previously reported in literature on benchmark datasets.

Summary: This paper investigates the behavior of P-time event graphs, a class of time Petri nets with non-deterministic timing of places, using combined linear descriptions in both (max,+) and (min,+) semirings. Necessary and sufficient conditions for the existence of extremal periodic trajectories are presented, derived from the new description, with a realistic example of an electroplating process to illustrate the results.

Summary: A LC-MS/MS method was developed for the simultaneous identification and quantification of cyanotoxins in edible bivalves. The method successfully detected and resolved two previously detected cyanotoxin congeners separately. The method showed limitations for certain cyanotoxins but overall was specific and robust for the parameters investigated. The method was applied to analyze mussel and oyster samples collected along the Swedish coast, and the results can contribute to future regulatory monitoring for cyanotoxins to ensure seafood safety.

Summary: The study investigated the structural performance of bivalve shells through finite element analysis and nanoindentation tests, revealing that hard clams perform best with thick shells, while blue mussels are better suited to thin shells. Soft clams experience the highest stresses under pressure and do not improve performance with changes in tested variables.

Summary: This paper investigates the capability of reconfigurable intelligent surface (RIS) to enhance wireless channels and improve outage performance in mobile edge computing (MEC) system. By considering computation offloading outage probability (COOP) as the metric, the coverage performance of RIS-assisted MEC system is studied. The closed-form expression of COOP is obtained and an asymptotic COOP expression at high transmit power region is derived. The proposed alternating optimization-based COOP min-max fairness (AOCMMF) algorithm achieves a suboptimal solution for the nonconvex min-max problem.

Summary: The cockle Cerastoderma edule is an important species in the Wadden Sea, but populations of shellfish-eating bird species have been declining dramatically. More comprehensive time series of cockle data are needed to analyze and explain ecological long-term changes in population dynamics and their impact on the food web.

Summary: Detailed analysis of Middle Eocene deposits in the Tamerza region reveals the presence of metric corrugated levels, representing shallow subtidal deposits of a moderate-energy environment. The petrographic examination of undulated facies and filamentous bivalves provides insights into the sedimentary processes and geological events within these levels. The differences in subfacies and the interpretation of shell beds as hiatal shell concentrations or transgressive system track deposits highlight the geological significance of these bio-events in establishing correlations between local basins during the Middle Eocene interval.

Summary: Urban waterlogging can lead to economic damage, inconvenience, and mortality. This study proposes a framework using a Weighted Naive Bayesian classifier and a Complex Network Model to assess urban waterlogging exposure. The proposed framework was validated and applied to the Guangdong-Hong Kong-Macao Greater Bay Area. The results showed a concentration of waterlogging risks in the downtown areas of populated cities, and the analysis revealed the factors contributing to the risks in different townships.

Summary: A population genetic study on the regional endemic table coral species, Acropora downingi, in the northeastern Arabian Peninsula revealed distinct genetic clusters between the Arabian/Persian Gulf and Sea of Oman populations. Despite a slightly structured population indicated by neutral markers, hypotheses such as bottleneck events and ecological speciation were considered to explain the observed genetic differences.

Summary: This study observed a fish species in an estuarine nursery ground on the southern coast of Portugal and found that 23.13% of the fish had anthropogenic particles in their gastrointestinal tract, with anthropogenic fibers occurring more frequently than fragments. Understanding the factors contributing to microplastic ingestion requires considering environmental conditions, species-specific feeding modes, and prey preferences.

Summary: The ecological state of the Persian or Arabian Gulf is declining sharply, and calls for comprehensive ecosystem-based management approaches and transboundary conservation have been mostly unanswered. It's important for scientists to engage in peer-to-peer diplomacy to build trust, share knowledge, and strategize marine conservation options across boundaries in order to meet global marine biodiversity conservation commitments.

Summary: The study aimed to analyze the ichthyoplankton assemblage in the Bons Sinais Estuary in India to understand the utilization of this area by species of socio-economic value. The dominant fish assemblage in this estuary was the Gobiidae family. Salinity, temperature, and water transparency greatly influenced the abundance and density of fish larvae in this estuary. The presence of fish larvae in the estuary indicates its importance as a nursery area for marine fish resources.

Summary: This study focuses on the monitoring and sampling of jellyfish in the seawaters of eastern Qatar. It presents the first records of jellyfish species in the Qatar pelagic ecosystem, including the semaeostome Chrysaora cf. caliparea and the rhizostomes Marivagia stellata and Catostylus perezi. The study conducted jellyfish monitoring, underwater photography, and sample collection along the eastern coast of Qatar. The findings provide a systematic description, general distribution, and sting risk assessment for the three species. The discussion highlights the blooming capabilities of Chrysaora cf. caliparea and Catostylus perezi, while Marivagia stellata appears to be scarcer.

Summary: This article provides a review on seafood consumption and sustainable fisheries. The study suggests that the involvement of all is necessary, and consumers should choose seafood products that are ecologically sustainable. The creation of school meal programs and the role of hospitality providers are identified as important steps in educating the public about seafood sustainability. Improving communication with consumers is crucial to raising awareness of sustainable consumption.

Summary: This study investigated the influence of environmental variables on the catch rates of striped red mullet by artisanal fishery using different time series models. The results showed that fishing effort had an effect on catch rates in certain areas. Upwelling and westerly winds were found to be the main drivers of catch rate variability across different regions. Furthermore, the study identified a consistent relationship between catch rates and environmental factors during the peak period of seasonal recruitment. The findings underscore the need for fisheries management to consider regional environmental effects in order to develop more effective assessment plans.

Summary: This study employed two types of questionnaires to validate the fishing gear and seasonality of fishing activities in the multi-gear coastal fleet in the Algarve, and additional fishing metiers were identified. The results obtained from the questionnaires contribute to a clearer understanding of the gear used and the distinction between target species and commercial by-catch.
