Demand for science and advice to address economic considerations is increasing, but the International Council for the Exploration of the Seas (ICES) does not engage many economists or address economic issues in many member countries. The Strategic Initiative on the Human Dimension (SIHD) has raised the profile of economics, but...
This paper presents findings from an investigation into the stay or exit decision of vessel owners in Scottish fisheries subject to stock recovery measures. Semi-structured in-depth interviews were conducted with 39 vessel owners during and following a vessel buy-back scheme. Empirical results show key factors affecting the decision to stay...
The financial success of the Scottish whitefish fleet is directly affected by the outcome of the December
2005 EU fisheries council where the fisheries management measures are decided.
To assist government, vessel owners and industry bodies at the December council negotiations, the
Seafish economics team has developed a cost and...
Douglas-fir provides social, economic, and ecological benefits in the Pacific Northwest (PNW). In addition to timber, forests support abundant plant and animal biodiversity and provide socioeconomic viability for many rural communities. Products derived from Douglas-fir account for approximately 17% of the U.S. lumber output with an estimated value of $1.9...
Scallop fishing was in effect a regulated open acceess fishery in UK until 2012 when the Western Waters management regime was implemented, limiting the maximum effort for the UK fleet of over 15m vessels and, via the UK government, limiting effort per vessel over 15m. This analysis identifies the main...
The majority of self-concept and sociometric research on crippled
children has been comparative studies in which the disabled child has
been a minority member within a group of physically normal children.
This study takes a different avenue in that it investigated the self-concept and peer reputation of physically handicapped children...
Situation: UK scallop fishing is input measures, with effort limits applied to >15m vessels only. There are no output limits. Industry members noted a decline in profits, and suggested that the effort regime was to blame. Government asked for evidence to support the claim and asked Seafish for economic analysis...
Seafish has undertaken an economic impact assessment (EIA) of the landing obligation for key UK fleets targeting demersal stocks. The purpose of the EIA is to provide information that supports decision-making and understanding at a fleet segment, home nation and national level. The EIA has been undertaken in two phases:...
Recently concerns over anthropogenic carbon pollution have received increased global attention and research in forest biomass and carbon sequestration has gained momentum. Light Detection and Ranging (LiDAR) remote sensing has in the last decade demonstrated forest measurement and biomass estimation potential. The project objective was to compare LiDAR forest biomass...
Temperature influences the incidence of chemically induced cancer in fish,
with warmer temperatures being associated with higher cancer incidence. The
mechanisms of temperature-modulated chemical carcinogenesis in fish, however,
have not been described in detail. Therefore, one primary objective of this study
was increased understanding of how temperature-modulated genotoxicity of 7,12-...
Effects of diet on food energy utilization by grass
carp fed aquatic plants or formulated diets with varied
lipid sources and levels are presented in three
manuscripts. Significant effects of diet on food
consumption, digestion, growth and muscle fatty acid (FA)
composition of fingerling diploid grass carp fed aquatic
macrophytes...
This presentation provides an overview of a keynote presentation given during a plenary session of the Industry and Policy Day held at the IIFET 2016 Scotland conference in July 2016. The session was chaired by Hazel Curtis and the presentation was given by Ernesto Penas Lado.
Light Detection and Ranging (LiDAR) remote sensing has demonstrated potential in measuring forest biomass. We assessed the ability of LiDAR to accurately estimate forest total above ground biomass (TAGB) on an individual stem basis in a conifer forest in the US Pacific Northwest region using three different computer software programs...
Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...
A series of session stakeholder presentations will address the current status, challenges, needs and future perspectives for implementation of management and ecological / economic assessment of data poor fish stocks and fisheries in management advice. This covers methods, simulation models and management strategy evaluation (MSE) tools to conduct assessment and...
Fish products are among the most highly-traded commodities. The proportion of fish harvests that is internationally traded has steadily risen over time. As a result, trade has become a key driver of the dynamics of local fisheries, with a range of ecological, economic and social impacts. This paper reports empirical...
