TL;DR: Stock synthesis implements compensatory population dynamics through use of a function relating mean recruitment to spawner reproductive output that enhances the ability of SS to operate in data-weak situations and enables it to estimate fishery management quantities such as fishing rates that would provide for maximum sustainable yield.

TL;DR: This paper defines integrated analysis, describes its history and development, gives several examples, and describes the advantages of and problems with integrated analysis.

TL;DR: In this article, the authors carried out an analysis of small-scale fisheries (SSFs) in Europe based on a selection of nine case studies and found that the most significant competitors are large-scale fleets, and recreational fisheries.

TL;DR: In this paper, the authors present a review of the current literature applying the Life Cycle Assessment (LCA) framework for the environmental assessment of fisheries and highlight energy use by fishing vessels, among other key factors determining environmental impacts.

TL;DR: In this article, the authors take a novel approach by characterizing post-landing trends of small-scale fisheries resources and estimating their total economic value, including both commercial and subsistence values, in a remote rural region in Madagascar.

TL;DR: The distribution and behaviour of Atlantic cod and pouting is affected by the presence and complexity of artificial hard substrates on the seabed, and population densities of both species were highly enhanced at the hard substrate habitats in comparison to the sandy sediments.

TL;DR: In this paper, the authors describe how acoustic, optical and radar sensors on ships, satellites and aircraft are used with forecast models to improve the management and harvesting of fisheries resources to help fishermen save fuel and ship time during their search for fish; to modelers who produce fisheries forecasts; and to scientists who help develop strategies for sustainable fisheries management.

TL;DR: This article showed that deep water species and habitats are under a more serious threat from fishing than hitherto assumed, and showed a linear increase in the mean depth of fishing of 62.5m −1, corresponding to an increase of about 350m for the period since 1950.

TL;DR: In this paper, two simple stock synthesis (SS) approaches were proposed to mimic the depletion-based stock reduction analysis (DB-SRA) estimation of overfishing limits (OFLs) currently applied to data-limited U.S. west coast groundfish species.

TL;DR: In this article, the authors examined the consequences of using the wrong recruitment assumption in the assessment used in the harvest strategy for setting the catches in south-eastern Australia, where the rate of ocean-warming is 3 to 4 times the global average.

TL;DR: In this paper, the authors developed a novel standardization method that uses continuous principal component scores, derived from a Principal Component Analysis of the catch composition data, as non-linear predictor variables for targeted effort within a Generalized Additive Model (GAM) framework.

TL;DR: In this article, the authors investigate the issue of sustainability and options for future development of small-scale fisheries by means of a case study in Majorca (Balearic Islands; W Mediterranean).

TL;DR: In this article, a framework or tool named tool for understanding resilience of fisheries (VA-TURF) was developed to assess the vulnerability of the coastal fisheries ecosystems in the tropics to climate change.

TL;DR: The fish recovered during live storage, but the haul size and duration influenced the blood and muscle pH significantly even after 6 h, and it was observed that 52% of examined fish had catch related damages; red discoloration, net markings and skin scratches.

TL;DR: In this article, two generic fish populations (long-and short-lived) subject to size and year-varying M were simulated, along with data used to fit statistical catch-at-age (SCAA) models.

TL;DR: In this article, the authors investigated the potential effects of current velocity on estuarine fish abundance data, and whether associated changes in bait plume size are important for benthic BRUV surveys in estuaries.

TL;DR: Underwater video can be a beneficial addition to a long-term trapping survey by increasing the frequency of occurrence for most reef fish species, which should translate into improved indices of reef fish abundance in the SUSLME.

TL;DR: In this paper, a case-study of artisanal fisherwomen in three communities on Ngazidja island, Comoros, was conducted to examine women's fishing methods, impacts, and contributions to coastal livelihoods and food security.

TL;DR: In this paper, a methodology to access fishers' ecological knowledge and local ecological knowledge (FEK) was designed under an ecosystem-based fisheries management framework, which was adapted from the Delphi technique, and focused on several spatial and temporal issues related to the small-scale fisheries of the northern coast of Brazil.

TL;DR: In this article, the authors used a passive acoustic telemetry array to study the movement patterns of Albula vulpes along the north coast of Cape Eleuthera, The Bahamas.

TL;DR: In this paper, a stochastic viability approach is proposed to address the trade-offs associated with balancing ecological, economic and social objectives in regulating mixed fisheries, taking into account the complexity and uncertainty of the dynamic interactions which characterize such fisheries.

TL;DR: In this article, the authors describe the creation of three small-scale area closures that serve to eliminate the exploitation and disturbance of discrete spawning aggregations of Atlantic cod and prevent the potential extirpation of these spawning components.

TL;DR: Analysis of blood samples obtained immediately after capture indicated that, relative to minimally stressed captive individuals, juvenile sand tiger blood biochemistry is disturbed after brief capture stress, and post-release survivorship is disturbed.

TL;DR: The results demonstrate the benefit of using a relatively thin single twine netting to ensure the appropriate size selection with round fish and the best results were obtained using netting with a T90 orientation.

TL;DR: Although juvenile white sharks were shown to overlap with gillnet fisheries in their vertical, horizontal and temporal distributions, post- release survival of sharks retrieved live in gillnets was high and Sharks were more often found live ingillnets when net soak times were low.

TL;DR: This review attempts to shed light on the possible links between the fecundity pattern and the specific environmental conditions encompassed by fish stocks and suggest future perspectives and conceptual models that could be developed in order to better explain and predict the feces pattern in fishes.

TL;DR: Wang et al. as discussed by the authors proposed a new opportunity for management of lake fisheries in China, where economic prosperity and improving awareness of environmental protection and food-safety concerns have provided a new window of opportunity for lake fisheries management.

TL;DR: In this article, the authors investigated the role of young-of-the-year alewives in the collapse of Atlantic cod along the northern 240 km of New England's historically productive coastal shelf.

TL;DR: In this article, the effects of three different light wavelengths (blue, red and white) were assessed on the composition, abundance and behaviour of nocturnal fish at the Houtman Abrolhos Islands, Western Australia.

TL;DR: In this article, a method for modeling size-selective mortality within a commonly-used assessment model, Stock Synthesis, is presented, which allows the normal distribution of length-at-age to be partitioned into three or five overlapping platoons with slow, medium, or fast growth trajectories.
