Abstract
In this chapter it is shown how economic evaluation algorithms of water use can be integrated into a long-term water management model such that surface-water availability and economic evaluation of various levels of water availability to different uses can be modeled simultaneously. This approach makes it possible to include essential features of economic analyses of water use into water resource modeling and thus improves the capability of such models to support decision making in water management. This is especially relevant for the implementation of the Water Framework Directive, which requires economic analyses to be included in the decision process about future water management strategies.
The water management simulation model WBalMo is presented and the integration of economic-evaluation algorithms is demonstrated for the examples of surface-water use for fish farming and for filling open-cast mining pits in order to achieve acceptable water-quality levels in the emerging pit lakes. Results of applying this integrated evaluation approach are shown for different water management scenarios under conditions of global change in the East German Spree and Schwarze Elster river basins, where water scarcity is an urgent issue. Among the lessons which are drawn by the authors one lesson reads that integrating economic evaluation algorithms into a pre-existing model might bring enormous problems. Therefore, such model approaches should be developed together by water engineers and economists in an interdisciplinary endeavor right from the start.

Abstract
Purpose
The aim of the paper is to gain a wide picture of competitive aspect of tuna farming industry, show its impact on the economy and society in Croatia, and to identify possibilities for improvement of current and future industry‐involved companies.
Design/methodology/approach
Research methodology used was desk research using benchmark of relevant published papers and analysis of official statistical data. Based on information gathered, the author developed its own analysis of a current state in the industry.
Findings
The paper provides an overview of tuna farming industry in Croatia, showing place for increasing the production due to stable demand but also the unused demand in domestic market. Still, there are a lot of barriers as a legal regulations, limited space and lack of supporting industries. With the involvement of companies and the country's representative bodies, the industry has potential to develop into stable economic activity.
Social implications
Tuna farming is based on seacoast and thus improves the demographical picture of those, usually sparsely populated areas. Also, it encourages the fishery of small pelagic fish.
Originality/value
The paper analyses tuna farming industry from its economic aspects, providing information and the base for further research of its economic potential and attraction.

Abstract
Dietary public health advice has been to consume fish. The fatty acids in fish, specifically the ratio of n‐3 to n‐6, are reported to be instrumental in determining the benefits. Looks at the available literature on differences in fatty acid composition between wild and farmed fish. Supports the hypothesis that farmed fish have a higher fat content and a different fat composition to wild fish. Suggests that more detailed studies, are required to compare the fat compositions of the various types of wild and farmed fish.

Abstract
Being a manager of his/her farmholding, the smallholder is described as having objectives and decisions. The smallholder is therefore a decision maker reflecting an organised decision‐making unit. These activities are carried out with the purpose of satisfying the small farmer’s goals as derived from objectives and priorities set. Farm level operations are upheld as a typical goal‐oriented system in which farmers’ decisions are taken in consideration with the prevailing environment and constraints. Chosen for this discussion are the Kisii, Vihiga and Kakamega areas of western Kenya. These areas are characterised by high population density, high agricultural potential area with reduced land, practising permanent cultivation with mixed farming, poverty and low incomes and unsteady food supplies. Basically this describes the smallholder environment and its constraints in relation to fish pond farming. What is apparent is the understanding of the environment and how it shapes the farmers’ operations in directing their decisions with reference to pond fisheries. Covered in this discussion are issues relating to farmer management strategies, decision‐making processes, decision making at the farm level and the information application processes.

Abstract
Purpose
Using a dialogic approach to narrative analysis through the lens of fairytale, this paper explores the shared construction of corporate environmental stories. The analysis provided aims to reveal the narrative messaging which is implicit in corporate reporting, to contrast corporate and stakeholder narratives and to bring attention to the ubiquity of storytelling in corporate communications.
Design/methodology/approach
This paper examines a series of events in which a single case company plays the central role. The environmental section of the case company's sustainability report is examined through the lens of fairytale analysis. Next, two counter accounts are constructed which foreground multiple stakeholder accounts and retold as fairytales.
Findings
The dialogic nature of accounts plays a critical role in how stakeholders understand the environmental impacts of a company. Storytelling mechanisms have been used to shape the perspective and sympathies of the report reader in favour of the company. We use these same mechanisms to create two collective counter accounts which display different sympathies.
Research limitations/implications
This research reveals how the narrative nature of corporate reports may be used to fabricate a particular perspective through storytelling. By doing so, it challenges the authority of the version of events provided by the company and gives voice to collective counter accounts which are shared by and can be disseminated to other stakeholders.
Originality/value
This paper provides a unique perspective to understanding corporate environmental reporting and the stories shared by and with external stakeholders by drawing from a novel link between fairytale, storytelling and counter accounting.

Abstract
Purpose
Marron farming in Western Australia has existed for decades. However, to what extent do marron growers see potential in this industry in ways that include expanding into hospitality and tourism? The purpose of this paper is to examine this dimension from a group of 26 marron growers.
Design/methodology/approach
The limited knowledge on marron farming from an academic, industry, as well as from operators' perspective is a critical factor in choosing a qualitative approach in this paper in the form of telephone and face‐to‐face interviews.
Findings
Overall, there is an agreement among respondents about the significant commercial potential of marron farming. However, the dilemma of satisfying increasing demand for marron is acknowledged, as well as resulting problems, for instance, in the form of greed and lack of unity among some growers.
Research limitations/implications
While the low number of respondents may not be sufficient to make generalisations of the marron farming industry, this paper proposes an overview into an unexplored industry, and provides useful insights into a niche market.
Practical implications
Increased demand for marron in both national and international markets presents opportunities for local operators and the future of marron farming. At the same time, a balance must be maintained in order to preserve natural resources and the industry's sustainability.
Originality/value
Despite its demand and potential, to date very limited research has been conducted on marron farming, particularly studying the links between marron, hospitality and tourism, as well as marron growers' points of views on this industry. This exploratory paper contributes to narrowing the existing knowledge gap on these dimensions.

Abstract
Purpose
This paper aims to explore how women entrepreneurs in informal settings, especially in the fishing sub-sector in rural communities, relate to different dimensions of innovation. Specifically, this paper examines how women entrepreneurs engage in process, managerial and technological innovations. This paper also examines how they fund their business, develop their products across the value chain innovatively and how it influences their business output and welfare.
Design/methodology/approach
A face-to-face structured interview was administered among 100 women entrepreneurs in the fishing agriculture sub-sector in the Anam community, Anambra East LGA, in Anambra State. The study uses the multiple logistic regression model, descriptive analysis technique and it is quantitative in approach. The research is situated within the Local Innovation Systems and adopts diffusion innovation theory.
Findings
The study established the following: level of education and learning capabilities are significant predictors of process innovation capabilities among women-owned enterprise in informal settings; level of education, years of fishing experience and learning capabilities are significant predictors of technological innovation capabilities among women-owned enterprise in informal settings; and level of education is the only significant predictor of management innovation capabilities among women-owned enterprise in informal settings.
Originality/value
This paper focuses attention on the issue of innovation by women who operate in the informal sector of the fishing sub-sector in the agricultural value chain with attention for their productivity and welfare.

This study aims to gain insights into the relevance and market potential of fish origin (farmed or wild) among consumers in Belgium, Norway and Spain.
Abstract
Purpose
This study aims to gain insights into the relevance and market potential of fish origin (farmed or wild) among consumers in Belgium, Norway and Spain.
Design/methodology/approach
Cross‐sectional data were collected through a consumer survey (n=1,319), conducted in November‐December 2007 in three European countries: Belgium, Norway and Spain. The study describes personal and food characteristics, as well as consumer attitudes and knowledge related to fish origin. Further, these characteristics were analysed in terms of their impact on the choice of either farmed or wild fish, using bivariate analyses.
Findings
In general, European consumers have little knowledge or awareness regarding the origin of fish. This results in uncertainty in consumers' perception of farmed fish in particular. The study is in line with previous ones suggesting that perceptions of aquaculture and farmed fish are based more on emotions than on rational considerations. Still, the perception of farmed fish is positive in general. Consumers do not prioritise fish origin as an information cue, although variation is present between different consumer groups. Consumers of predominantly farmed versus wild fish did not have a very distinct profile, which corroborates with the only modest significance of fish origin as a product‐specific information cue during the fish purchase and consumption decision process.
Originality/value
The strength of the paper pertains to its international scope, and to the diversity of countries selected in terms of relevant variables. Also, the growing relevance of aquaculture as a fish production method and farmed fish as a food product makes results and findings of the study topical and of practical relevance.

Abstract
This study employs a focus group methodology to examine the factors affecting the acceptability of gene technology in food production, using genetically modified (GM) farmed salmon as a focus for the research. The results identified a small group of “triers” ‐ willing to try any GM food product, and a small group of “refusers” ‐ rejecting the technology and derivative products. For the middle majority of “undecided” consumers, the decision to accept or reject GM food products was based on a number of interrelated factors, associated with the food product and the benefits conferred.
