TL;DR: In this article, the authors describe how certain tools and tactics can be integrated into recreational fishing practices to marry best angling practices with the realities of angling, and outline available methods for assessing fish condition.

TL;DR: In the Barents Sea, the distribution of commercial species of fish and shellfish is observed in the summer period, and is related to increased inflow of Atlantic Water and reduced ice cover as mentioned in this paper.

TL;DR: Any evaluation of harvest policies for forage fish needs to include issues, and models tailored for individual species and ecosystems are needed to guide fisheries management policy.

TL;DR: In this paper, several case studies from diverse geographic areas exemplify the union of aquaculture technology, quantitative modelling, social science, physiology and ecology to estimate enhancement potential, improve enhancement strategies, assess enhancement outcomes, and support adaptive management.

TL;DR: In this article, a method to estimate the relative catch efficiency of different fishing gear designs based on comparison of catch data is described, which does not require an equal number of deployments or alternation between gears, but accounts for multiple competing models describing the data by using multi-model inference.

TL;DR: The epidemiological survey was carried out to provide the basis for analysis and prediction of consumer exposure risk due to the presence of anisakid nematodes in fish from European wild-catch fisheries, and represents the largest and most comprehensive epidemiological data compilation of an isakids ever generated.

TL;DR: Routine reporting of how prey condition influences identification, the specific approaches used, and any assumptions made in identifying prey are recommended, and %F data should be reported as a nested hierarchy of taxonomic levels which allows these data to be readily standardised across studies and used in meta-analyses.

TL;DR: It is suggested that the National Parks, which are No Take Zones (NTZs), and the fisheries regulations inside and outside of Reserves are inadequate for maintaining or restoring reef fishery target families under current levels of fishery exploitation.

TL;DR: The methods used to date to study fisheries competition with seabirds are reviewed, “best practices” for future resource competition assessments are presented, and an integrated approach is most promising to obtain robust scientific results.

TL;DR: In this article, the authors used three divergent case studies to demonstrate the value of using qualitative social science approaches to complement more conventional quantitative methods to improve the knowledge base for fisheries management.

TL;DR: An integrated management strategy is proposed for the blue crab in SEW, including the Mediterranean and Black Sea and the eastern Atlantic coasts of the Iberian Peninsula, and an appraisal of the current trends in global and European crustacean fisheries is concluded.

TL;DR: This review summarizes various applications of next-generation sequencing that has been used in fishery research up to now and underscores the need to understand well genetic and biological significance of investigated species for fisheries and aquaculture.

TL;DR: This work provides a framework for model development that identifies and corrects model misspecification and illustrates the framework, using simulated data, which is computationally intensive and practical approximations are available, computational algorithms are being improved, and computer power is increasing.

TL;DR: In this paper, the Dirichlet-multinomial distribution is incorporated into stock synthesis, and a model-based method for estimating effective sample size is proposed. But this method does not propagate uncertainty about data weighting when calculating uncertainty intervals, and often are not re-adjusted when conducting sensitivity or retrospective analyses.

TL;DR: This study suggests that methods of stock discrimination based on early incremental growth are likely to be effective, and that automated classification techniques will show little benefit in supplementing early growth information with shape indices derived from mature outlines.

TL;DR: In this article, the authors performed a content and discourse analysis of an online discussion forum used by the largest land-based shark fishing club in Florida and identified a minimum of dozens of cases of illegal shark fishing practices among forum users.

TL;DR: This study is the first Mediterranean-wide epidemiological assessment of infection in the viscera and flesh of E. encrasicolus by A. pegreffii, an important causative agent of human anisakiasis.

TL;DR: This paper revisits topics addressed in two previous papers on data weighting in fisheries stock assessment models and discusses some new topics: most iterative reweighting of composition data is multiplicative, but additive methods deserve consideration.

TL;DR: Simulation methods are used to evaluate the ability of commonly-used and recently-proposed diagnostic tests to detect model misspecification in the observation model process, systems dynamics, and incorrect data weighting and suggest multiple carefully selected diagnostics can increase the power to detect misspecify without substantially increasing the probability of falsely concluding there is misspecified models.

TL;DR: In a survey conducted in Spain, the majority of consumers were willing to pay extra for an Anisakis-free product, indicating a willingness to pay 10% above the usual fish price at market (6.60€/ kg compared with 6€/kg) as discussed by the authors.

TL;DR: In addition to high prevalence and abundance values, the cod sampled in this study presented a diversity of ascaridoid nematodes with a majority of fish displaying a co-infection.

TL;DR: Results indicate that the otolith microchemisty and morphometry and scale morphometry are acceptable markers of habitat and represent a potential tool (in combination or individually) for the identification of streaked prochilod nursery areas.

TL;DR: In this article, the authors determined the Sr:Ca and Ba:Ca ratios in otoliths, by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS).

TL;DR: In this article, the authors analyzed incidental catch records of white sharks from the US-Mexico border to Bahia Sebastian Vizcaino (BSV) and evaluated whether Heupel et al. (2007) criteria for the identification of shark nursery areas were met for BSV.

TL;DR: In this paper, the authors used Rastrelliger kanagurta fishing-catch data during the high-catch season in the second quarter, which was from April to June (2008 and 2009), and satellite data of chlorophyll-a (chl-a), and sea surface temperature from MODIS-Aqua.

TL;DR: In this article, an adaptive and integrated socio-ecological framework to optimize production potentials and enhance sustainability through production clusters is proposed, and the viability of this was tested in northern Palawan and south central Mindanao in partnership with commercial marine fish culture companies and small-scale fishers.

TL;DR: The results support the idea that the best fishing ingredients are investing time and maximizing encounter probabilities through habitat choice, with only moderate additional effects to be expected from attention to abiotic conditions, day time and choice of type of artificial lure.

TL;DR: In this article, the authors compared the performance of AD and UVP methods by a ring trial (RT) involving highly experienced laboratories and evaluated the potential transferability of the best performing method to the industry.

TL;DR: In this article, the authors used the lessons learned from >10 years of research and conservation of the Caribbean flats fishery are used to demonstrate how C&R Fishery Evaluation Guidelines (FEGs) can be applied to this and similar catch and release fisheries.

TL;DR: This article used spatio-temporal binomial generalized linear mixed models (GLMMs) to map the long-term spatial distributions of older juveniles and adults of red and gag groupers in the U.S. Gulf of Mexico.
