The objectives of this paper are to analyze the drivers of smoked marine fish prices and examine the challenges along the value chain to inform policy.

The study relies on cross-sectional data from 158 fish smokers, 100 wholesalers, and 120 retailers in Ghana. The challenges faced by the actors along the chain are identified and ranked using Kendall's coefficient of concordance. The three-stage least square estimation approach is employed to control for endogeneity resulting from the simultaneous equations for prices of different fish types and their substitutes.

The results reveal that marketing experience, the extent of competition, price of substitutes, payment terms, and variable cost items, such as transportation cost and storage charges, are key determinants of smoked fish prices along the value chain. Lack of access to credit is the main constraint to the marketing of smoked marine fish, irrespective of the actor or the fish type.

Many studies have established the linkages between fish consumption, prices, and food security in the literature. However, there is a dearth of information on the responsiveness of fish prices to changes in the market and seller-specific factors to drive policy to stabilize prices along the value chain.

This paper examines the prices of fishery products (an important source of protein for the poor) and drivers of their inter-regional variations in India, where fishery is a critical sector. By explaining regional price differences, we make an attempt to derive policy implications as to how fish price inflation can be controlled.

The paper is primarily based on secondary data provided by the Ministry of Agriculture, Government of India. In the absence of data on inter-regional trade, appropriate indicators are constructed using the gravity model to capture supply side factors that may influence regional price differences. Pooled regressions are carried out for a representative marine and an aquaculture fish variety separately for the period 2011 to 2017.

After controlling for income levels, it is found that marine fish prices can be reduced by improving intra-state transport infrastructure. For reducing the price of aquacultures, it is shown that it is imperative to reduce the distance between producers and consumers.

The study is limited by the availability of data on interstate trade and consumption of fish and has only used prices of representative fish varieties instead of average marine and aquaculture fish prices.

This paper considers trade and value chain based business theories to explain regional price differences. It analyzes the drivers of relative price differences and suggests measures to control them using a gravity model of trade.

This paper aims to put forward and compare two accessible approaches to model and forecast spot prices in the fishing industry. The first modelling approach is a Markov-switching model (MSM) in which a Markov chain captures different economic regimes and a stochastic convenience yield is embedded in the spot price. The second approach is based on a multi-factor model (MFM) featuring three correlated stochastic factors.

The two proposed approaches are analysed in terms of parameter-estimation accuracy, information criteria and prediction performance. For MSM’s calibration, the quasi-log-likelihood method was applied directly while for the MFM’s parameter estimation, this paper designs an enhanced multi-variate maximum likelihood method with the aid of moments matching. The numerical experiments make use of both simulated and actual data compiled by the Fish Pool ASA. Data on both the Fish Pool’s forwards and Norwegian T-bill yields were additionally used in the MFM’s implementation.

Using simulated data sets, the MSM estimation gives more accurate results than the MFM estimation in terms of the norm in ℓ² between the “true” and “computed” parameter estimates and significantly lower standard errors. With actual data sets used to evaluate the forecast values, both approaches have similar performances based on the error analysis. Under some metrics balancing goodness of fit and model complexity, the MFM outperforms the MSM.

With the aid of simulated and observed data sets examined in this paper, insights are gained concerning the appropriateness, as well as the benefits and weaknesses of the two proposed approaches. The modelling and estimation methodologies serve as prelude to reliable frameworks that will support the pricing and risk management of derivative contracts on fish price evolution, which creates price risk transfer mechanisms from the fisheries/aquaculture sector to the financial industry.

The study here examines how business actors adapt to changes in networks by analyzing their perceptions or their network pictures. The study is exploratory or iterative in the sense that revisions occur to the research question, method, theory, and context as an integral part of the research process.

Changes within networks receive less research attention, although considerable research exists on explaining business network structures in different research traditions. This study analyzes changes in networks in terms of the industrial network approach. This approach sees networks as connected relationships between actors, where interdependent companies interact based on their sensemaking of their relevant network environment. The study develops a concept of network change as well as an operationalization for comparing perceptions of change, where the study introduces a template model of dottograms to systematically analyze differences in perceptions. The study then applies the model to analyze findings from a case study of Norwegian/Japanese seafood distribution, and the chapter provides a rich description of a complex system facing considerable pressure to change. In-depth personal interviews and cognitive mapping techniques are the main research tools applied, in addition to tracer studies and personal observation.

The dottogram method represents a valuable contribution to case study research as it enables systematic within-case and across-case analyses. A further theoretical contribution of the study is the suggestion that network change is about actors seeking to change their network position to gain access to resources. Thereby, the study also implies a close relationship between the concepts network position and the network change that has not been discussed within the network approach in great detail.

Another major contribution of the study is the analysis of the role that network pictures play in actors' efforts to change their network position. The study develops seven propositions in an attempt to describe the role of network pictures in network change. So far, the relevant literature discusses network pictures mainly as a theoretical concept. Finally, the chapter concludes with important implications for management practice.

Studies of the marketing and distribution of fish have examined a declining industry, which, in response to trends in fish consumption and major developments in the food retailing industry, has undergone profound alterations. The shift in demand from fresh to frozen fish and the decline in the number of traditional fishmongers have been of particular importance in effecting changes in the distribution of fish. This article aims to remedy the neglect of the inland markets. By analysing their present roles and identifying their particular functions within the wider marketing system, it should be possible to offer a clearer perspective on their present and future roles.

Concerns itself with the growth prospects for the West African fishing industry, decides that attempts to reform marketing in isolation from the system of financing will be unsuccessful. Wonders what can be done to identify constraints to trade, and this involves more than a mere understanding of economic processes. Attempts to show the response of marketing institutions to technical innovations and economic growth in the hope that it will provide some empirical data to modify Western economic concepts that are generally applied to developing economies. Concludes that generalisation for all developing economies are not possible.

The purpose of this paper is to provide a profile of fresh fish consumers and analyze trends in their choices of fresh fish. In addition, this study investigates whether being an active practitioner of angling or whether belonging to a household with angling activity has an effect on consumers' choices.

Consumers' habits, profiles, and perceptions were obtained from randomized personal interviews (n=395) at traditional markets (the main source of fresh fish for Spaniards) and from interviews with restaurant managers (n=11) carried out on Mallorca Island, in the West Mediterranean, in 2009.

A wide range of middle‐aged and middle‐class residents consumed fresh fish. The residents in the sample preferred to buy fish in traditional retail markets and consumed fish at least once a week, including a wide range of species. Consumers were satisfied with the quality of the fish but were moderately unsatisfied with the information that they received about the fish and fisheries. Although fish price was a factor in decisions to purchase, consumers were willing to pay more for local products of good quality. A significant proportion of individuals in the sample were themselves recreational fishers or belonged to households with recreational fishing members. These individuals shared a different consumer profile, tending to prefer local species that come at higher prices. A parallel survey of fish restaurants showed differences in preferred species depending on customers' place of residency and nationality.

The consumer trends that were identified and the perception of fresh fish captured by local fleets might have implications for commercialization and fishery management.

This is the first study of consumer choice related to leisure activity in a country with a very high rate of fish consumption.

The purpose of this paper is to separate households into several types based on their features, and then to further investigate determinants of household fish consumption in China by figuring out consumption preference divergences between types of households under the effects of economic and socio-demographics factors.

This paper first applies Multiple Correspondence Analysis to separate the modalities of variables and households according to their features, with health knowledge and time constraint of a spouse highlighted. Then, the transcribed principal information of both variables and households has been added into Marshallian demand function with fish price, income, child effect, and health status for identification of factors on household fish demand. The robust fixed effect and robust random effect GLS regression has been conducted.

The paper provides empirical insights about what and how factors affect household fish consumption. It suggests that, for all households, pork is still a main substitution of fish, fish consumption regarding to each household should be constant, and fish consumption differs a lot between provinces. For households with higher dietary knowledge, the authors found that increase of income, the existence of adolescent would cause an increase in fish consumption, while illness of household member makes a decrease in fish consumption. For households with working women who have higher opportunity cost of time pursue much more convenience, then consume less fish at home than their counterparts.

The increasing variety in consumer’s dietary need makes the understanding of which becoming much more difficult than before. This paper uses three-wave panel data with households spread over nine provinces in China, but the results still has its limitation since china is the one with vast in territory and residents. In the future, the difference between urban and rural area in fish consumption need further research.

The paper reveals the common determinants of fish consumption in China, and makes a further clear answer by a further discussion on different household types. The results have rather high implications for making targeted policy or precisely forecasting a future fish demand in China, which will rather be helpful for fishery industry development in China.

This paper fulfills an identified need to study the divergence of determinants or the impact degree of different factors on fish consumption in China by household types. An increasing trend of food away from home has significant effect on how to count household size in food consumption studies, and the identification of persday in this study shows its advantages in dealing with this issue, which makes a contribution on resolve the overestimation of household size issue.

Food consumption patterns have changed in many Asian countries over the past two–three decades. It is important to understand the changes in food consumption patterns and its drivers in different country settings as each country has different food cultures, tastes and habits. Thus, the purpose of this paper is to examine the patterns and determinants of food consumption choice and demand in Sri Lanka.

Using Household Income and Expenditure Survey 1990/1991, 2002 and 2012/2013 data, this study explores the relationship between food consumption patterns and the observed changes reported in per capita income, urbanization, structural transformations and demographics. Specifically, present study estimates the probability of consuming main food items such as rice, bread, dhal, vegetables and fish using a multivariate probit model and also estimates income and price elasticities of household major food items by applying Quadratic Almost Ideal Demand System.

This study demonstrates that per capita income, food prices, education level of the household heads, rural–urban affiliation and ethnic background significantly affect the consumption decision of the major food items. Sri Lankan households in general seem to consider that rice and dhal are necessary commodities, whereas bread and fish are luxury commodities.

The lack of panel data and several missing districts in two survey rounds for analysis are limitations of the study.

To the author’s knowledge, this is the first study for Sri Lanka that examines food consumption choice and demand using nationwide data for the last two decades. This study applies novel econometric techniques to account for various issues in data analysis.

This paper examines the problems of launching new products onto the market, particularly healthy foods and fish products. Research was undertaken to investigate whether consumers would be prepared to purchase a new concept, i.e. polyunsaturated fatty acid (PUFA) fed fish, premium price PUFA fish and different species of PUFA fish, specifically salmon, eel and sturgeon. The factors influencing the respondents’ decisions were investigated. The methodology utilised a questionnaire containing both qualitative and quantitative questions and several group discussions. It was found that the majority of the sample found the concept of PUFA fish acceptable and plausible and were prepared to pay a premium price, but the number of people prepared to purchase specific PUFA species was lower. Although health was given as a main reason for purchase other factors such as image, physical appearance of the whole animal, sensory properties, the type of product and the price also had to be satisfied for a clear purchase intention to be indicated.
