Feeding responses of hatchery-reared gilthead sea bream (Sparus aurata L.) to a commercial diet and natural prey items
Provedor de dados: 5
Autores: Andrew, J; Begout, Marie-laure; Kadri, S; Holm, J; Huntingford, F.
Many fish species have evolved feeding mechanisms and behaviours enabling them to feed on specific prey. However, such mechanisms may not be optimal for feeding on commercial-pelleted diets in aquaculture. Gilthead sea bream chew and occasionally eject pellets or parts of pellets from the mouth when feeding on commercial diets. This may result in an increase in nutritional waste from the intensive culture of this species. In this study we examined the prevalence of this food processing behaviour in two sizes of sea bream, feeding on three types of natural prey items in comparison to a commercial pellet, to give an insight into the circumstances in which excess chewing and ejection of food items from the mouth occurred. These included two hard-textured food...

Haliotis tuberculata   , a generalist marine herbivore that prefers a mixed diet, but with consistent individual foraging activity
Provedor de dados: 5

While population foraging behaviour of herbivores has been extensively studied, individual choice is still poorly understood. Very few studies have focused on the individual consistency of foraging behaviour in marine herbivores. Because marine ectotherms are strongly influenced by their environment and because a mixed diet is appropriate for herbivores, we hypothesized that Haliotis tuberculata, a large marine gastropod, would not exhibit significant individual consistency in foraging activity and would display generalist food choices. To test these hypotheses, the behaviour of 120 abalone was studied using a choice test of eight macroalgal species over 3 weeks, with video recording 24 hr a day. In addition, primary components, secondary metabolites and...

PRIVATE LABELS: A MECHANISM FOR FULFILLING CONSUMER DEMAND FOR HEALTHY FOOD?
Provedor de dados: 31
Autores: Weaver,   Robert D.; Moon,   Yongma.
As consumer preferences rapidly evolve with respect to health-related attributes of food, many have questioned the performance of the conventional food industry to fulfill new demand. As the structure of the industry has shifted toward conditions where retailers have access to and incentive to respond to rapidly changing information concerning consumer preferences, it is relevant to consider the conditions under which retailers will offer private labeled healthy food products not available from national brand manufacturers. This paper presents a theory of the dynamic, stochastic decision of retailers to offer private label products that are close substitutes to national brands. Within the context of salient features of healthy foods, we examine the role of...

Food Away From Home: How much does it really influence diet quality?
Provedor de dados: 31
Autores: Mancino,   Lisa; Todd,   Jessica E.; Lin,   Biing-Hwan.
This study confirms that eating food away from home (FAFH) adversely affects dietary intake. By looking at changes within individuals’ dietary intake over two days, thus controlling for self-selection issues, we find that FAFH causes increased caloric intake and reduced diet quality. Our estimates on the effect of specific meals show that lunch and dinner consumed away from home have the largest effect on total daily caloric intake, but that breakfast has the largest negative effect on total diet quality. In particular, eating breakfast away from home decreases intake of fruit, whole grains and dairy and increases the percent of calories from saturated fats and solid fats, alcohol and added sugar. Eating lunch and dinner away from home also reduce diet...

Investigating Thai Shopping Behaviour: Wet-Markets, Supermarkets and Food Quality
Provedor de dados: 31
Autores: Gorton,   Matthew; Sauer,   Johannes; Supatpongkul,   Pajaree.
An analysis of primary survey data on Thai shopping behavior seeks to understand the relative satisfaction of consumers with wet markets and supermarkets and identify the factors that affect frequency of visit to, and purchase behavior within, these retail outlets. This is used as a basis for engaging in wider debates on the ‘supermarket revolution’ in Asia. On all salient attributes affecting retail outlet choice, wet markets are perceived, in general, to be inferior to supermarkets. However for fresh produce sales, wet markets retain an advantage. Both socio-economic characteristics and retail outlet attributes are considered as determinants of food shopping behavior. Bootstrapped bivariate ordered probit models identify that those using wet markets more...

Take off the heater: Utility effect and food environment effect in food consumption decisions
Provedor de dados: 31
Autores: Lombardini-Riipinen,   Chiara; Lankoski,   Leena.
In this paper, we describe individual food consumption decisions as driven by a utility effect and a food environment effect. To outline the utility effect, we first develop a new theoretical model of individual food consumption. Next, we introduce the food environment effect by showing how the food environment can affect food consumption decisions and how this can skew the resulting food consumption vector. Finally, we analyse manipulations of the food environment as a potential form of policy intervention. Our key result is that the food environment has several entry points in food consumption decisions and that libertarian paternalistic manipulations of the food environment can be effective, easily implemented, well-accepted and low-cost intervention...

Unstable Individual Bids and Stable Market Demand
Provedor de dados: 31
Autores: Alfnes,   Frode; Rickertsen,   Kyrre; Shogren,   Jason F.
We explore preference stability at the individual and market level. We examine individual bidding behavior among 116 French consumers who participated in experimental auctions conducted seven months apart for five types of fish. We reject preference stability at the individual level, but not at the aggregate market level.

Determinants of Food Choice in a Transitional Economy: Insights from the Theory of Reasoned Action
Provedor de dados: 31
Autores: Petrovici,   Dan Alex; Ritson,   Christopher; Ness,   M.
This paper draws upon a consumer survey carried out in Bucharest (Romania) to explore determinants of food choice in a transition economy. An adapted version of the Theory of Reasoned Action was developed. This included attitude toward intention, habit and preference as independent variables. The structural equations modelling carried out in 'Analysis of MOment Structures' AMOS showed a significant positive influence of all variables. Similar to other studies conducted in European Union (EU) countries (Saba, Di Natale, 1998) habit outweighed the other variables. The study emphasises the heterogeneity of consumer beliefs about food. Furthermore it was suggested that there is scope for noneconomic variables in explaining food choices and consumer behaviour...

Choosing ‘buy none’ in food choice analysis: the role of utility balance
Provedor de dados: 31
Autores: Campbell,   Danny; Doherty,   Edel; Gibson,   Vikki.
Stated choice analysis is now a widely used and accepted methodology for exploring food choice. In stated choice experiments respondents are asked to make a choice between two or more alternatives, one of which typically takes the form of a ‘buy none’ option. It is widely recognised that respondents often perceive this option differently from the other alternatives and various reasons for this have been offered. Nevertheless, the role that utility balance among the experimentally designed options plays on the propensity of respondent’s choosing ‘buy none’ has largely been overlooked. Using a non-linear representation of utility we show that the ‘buy none’ choices are sensitive to utility balance. We further show how accommodating this provides an...
