The Pacific sardine (Sardinops sagax) has been one of the most abundant fish in the California Current Ecosystem (CCE) since the late 1990s. In recent years under a warm regimen, large Pacific sardine reached Canadian waters in mid-June and returned to the spawning ground in Southern California during October. The...
The documentation of sustainability constitutes a significant opportunity for product value-adding in the captured fish sector, and a means of differentiating sustainably caught and landed fish from inferior alternatives. In the industry-owned R&D project WhiteFish the main objective is to create a tool for catch and processing SMEs in the...
The study investigated fresh fish characteristics that determine consumers' preference for fresh fish in rural and urban households. Primary data were collected from a total of 192 fresh fish consumers using multi-stage sampling procedure. The data were analyzed using descriptive statistics, regression analysis and Relative Attribute Model (RAM). The results...
It is commonly acknowledged that body weight of fish is a key factor in determining market value of landed catch, thus influencing optimal harvest strategies. However, in management strategy evaluations and bioeconomic modelling, body size is often an overlooked economic parameter, and there are no systematic studies on the prevalence...
Warming of the Arctic has taken place with a loss of sea ice and changes in the Arctic ecosystem. Valuable commercial species may move northward and large-scale commercial fishing may be proposed. This paper considers the potential for commercial fisheries in the Arctic, much of which is international waters, and...
Despite to the high fishing pressure; use of illegal fishing methods; deforestation, manufacturing, tourism and even the dynamic market environment, an artisanal stake-net fishery, which operates for shrimps, has been able to survive since 1721 in Negombo lagoon in the western Sri Lanka. The key strength of the stake-net fishery...
"Infrastructure facilities of landing sites, which are the core of the fishing industry in Sri Lanka, were severely damaged by the tsunami in December 2004.
Currently these facilities are being rebuilt in association with various non-governmental organisations. At present there are large numbers of small anchorages which require development of...
Fishers are faced with multiple risks, including unpredictability of future catch rates, prices and costs. While the latter are largely beyond the control of fisheries managers, effective fisheries management should reduce uncertainty about future catches while also enhancing profitability. Different management instruments are likely to have different impacts on the...
Stronger microeconomic foundations to dynamic renewable resource models lead to rethinking the commons problem. Specifications of technology consistent with microeconomics allow reinterpretating the market failure under open access for common resources, the dynamic economic optimum, and global commons issues in general. The market failure is broader and deeper than previously...
The main objective of this study was to describe the marine artisanal fishery in Tanzania mainland by manipulating data from frame and catch assessment surveys from 1984 -2011. Results showed that catches have been fairly stable while fishing effort has been increasing leading to decline in CPUE. This could be...
Whole-genome duplications are radical evolutionary events that have driven speciation and adaptation in many taxa. Higher-order
polyploids have complex histories often including interspecific hybridization and dynamic genomic changes. This chromosomal
reshuffling is poorly understood for most polyploid species, despite their evolutionary and agricultural importance, due to the
challenge of distinguishing...
Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that...
Biotic resistance is the idea that native species negatively affect the invasion success
of introduced species, but whether this can occur at large spatial scales is poorly
understood. Here we re-evaluated the hypothesis that native large-bodied grouper
and other predators are controlling the abundance of exotic lionfish (Pterois volitans/miles) on...
Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the
spatial distribution of marine species. However, there is still a gap in the development of concepts and techniques for its
application in the marine pelagic realm, where there are no clear boundaries delimitating...
The ascomycete Geosmithia morbida and the walnut twig beetle Pityophthorus juglandis are associated with thousand

Forest understory vegetation is influenced by broad-scale variation in climate, intermediate-scale variation in topography, disturbance and neighborhood interactions. However, little is known about how these multi-scale controls interact to influence observed spatial patterns. We examined relationships between the aggregated cover of understory plant species (%C[subscript U]) and multi-scale controls using...
This article examines the influence of Emmanuel Levinas’s philosophy on the ethical aspects of the life and work of André Schwarz-Bart. The essay is framed through recent re-interest in Schwarz-Bart’s collaborative works with his wife, Simone, as a bridge between Holocaust and postcolonial studies. The publications, arguments, and key points...
To determine effects of intraarticularly administered tiludronate on articular cartilage in vivo, eight healthy horses were injected once with tiludronate (low dose tiludronate [LDT] 0.017 mg, n = 4; high dose tiludronate [HDT] 50 mg, n = 4) into one middle carpal joint and with saline into the contralateral joint....
Many microbial, fungal, or oomcyete populations violate assumptions for population
genetic analysis because these populations are clonal, admixed, partially
clonal, and/or sexual. Furthermore, few tools exist that are specifically designed for
analyzing data from clonal populations, making analysis difficult and haphazard.
We developed the R package poppr providing unique tools...
INTRODUCTION: Tissue engineering is a new methodology for addressing meniscal
injury or loss. Synovium may be an ideal source of cells for in vitro meniscal fibrocartilage
formation, however, favorable in vitro culture conditions for synovium must be
established in order to achieve this goal. The objective of this study was...
Temperature-dependent fecundity and survival data was integrated into a matrix population model to describe relative

Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...
Excess fatty acids and sterols are stored as triacylglycerols and sterol esters in
specialized cellular organelles, called lipid droplets. Understanding what determines the cellular
amount of neutral lipids and their packaging into lipid droplets is of fundamental and
applied interest. Using two species of fission yeast, we show that cycling...
We report the first systems biology investigation of regulators controlling arterial plaque macrophage transcriptional changes in response to lipid lowering in vivo in two distinct mouse models of atherosclerosis regression.

Bulk magnetic properties of soils and sediments are often sensitive proxies for environmental change but commonly require interpretation in terms of the different sources of magnetic minerals (or components) that combine to generate them. Discrimination of different components in the bulk magnetic record is often attempted through endmember unmixing and/or...
The search for and discovery of early archaeological sites is an inherently geoarchaeological problem. Archaeological sites of late Pleistocene-age are known to be located in the Intermountain West, however, the record of these early sites remains limited to only a few examples. In the lower Salmon River canyon (LSRC), the...
Ecolabelling has become an essential component of the global sustainable seafood trade. The MSC is currently the world leader in certification and ecolabelling programs for wild capture fisheries. While the environmental benefits of certification have been widely recognised, its economic benefits are often anecdotal or unknown. The South African hake...
This study evaluates existing market-based incentive mechanisms, such as Marine Stewardship Council (MSC) certification, Fishery Improvement Projects (FIPs), and International Seafood Sustainability Foundation (ISSF) associate membership, as innovative instruments for tuna fishers to improve sustainability of their fishing methods. There is little knowledge on ways these types of incentive mechanisms...
Western Australian (WA) fisheries have a long association with environmental certification- the WA rock lobster fishery (in 2000) was the first fishery certified under the Marine Stewardship Council (MSC) standards.In 2012 the Western Australia Minister of Fisheries announced that the State Government had committed $14.6 million across a four-year period...
There are three main aspects of sustainability; the environmental, the social and the economic. When it comes to fisheries, stock sustainability is particularly important and the stock and ecosystem health has significant effects both on the environment and on the sector economy. In order to add value to a product,...
Small-scale fisheries make key contributions to food security, sustainable livelihoods and poverty reduction, yet to date the economic value of small-scale fisheries has been poorly quantified. In this study, we take a novel approach by characterizing post-landing trends of small-scale fisheries resources and estimating their total economic value, including both...
The main instrument used in fishery management is the total allowable catch (TAC). Fishery management often fails because TACs are set too high and do not sufficiently restrict fisheries. The question we address in this paper is why do decision makers choose inefficiently high TACs? Our approach is to model...
Integrating governance mechanisms into bio-economic modeling tools is a key challenge for the assessment of fisheries management plans. Impact assessments are carried out without considering real management options and institutional context. Only fishing mortality changes and their impact on fish stocks are considered. The Bay of Biscay sole fishery offers...
The introduction of individual fishing quotas (IFQs) in the Gulf of Mexico red snapper fishery significantly impacted the way the commercial fleet operated. As result of the added flexibility afforded by the IFQ program, vessels began taking fewer but longer trips. They also began diversifying the composition of their catch....
Rights-based fisheries management programs allocate to fishermen a specified portion of the annual TAC, providing fishermen with the incentive to optimize the value of this share, which has been shown to lead to more economically efficient behavior. Less efficient operators will tend to leave the fishery, decreasing overcapacity, but this...
Two of the primary issues of the next Common Fisheries Policy (CFP) reform are maximum sustainable yield (MSY) and transferable fishing concessions (TFCs). The European Commission set the goal of achieving MSY for all European fisheries by 2015. Besides, the European Commission agreed on implementing TFCs under some major principles...

MOTIVATION: Estimation of bacterial community composition from
a high-throughput sequenced sample is an important task in
metagenomics applications. Since the sample sequence data
typically harbors reads of variable lengths and different levels of
biological and technical noise, accurate statistical analysis of such
data is challenging. Currently popular estimation methods are...
ITQ systems generate ITQ prices. For any given ITQ-managed species there are typically two prices. One is for the annual (or seasonal) quota, the other is for the longer lasting ITQ-share. In well-functioning ITQ markets, these prices reveal important information about the fishery. In the single species framework, prices of...
Gender inequalities pervade aquaculture and fisheries. Participation is marked by strong gendered divisions of labour, and sector policy is gender-blind even though sociological and ethnographic studies show that policy impacts are highly gendered. In projects concerned with economic development, the main approach taken to address inequalities is to “empower women,”...
We investigate the effects of incorporating a fixed input on equilibrium profits and biomass. We first set up a theoretical model with an input that is fixed in the short-run (vessel size) but that can be used with a variable input at suboptimal capacity. We use this model to get predictions for...
In Bangladesh, women constitute about 50% of the population but comprise only one-fourth of the labor force. Considering women's critical roles in fisheries sector many projects in Bangladesh address both men and women as target groups putting more emphasis on women groups.
