A Comparison of Risk Exposure in Aquaculture and Agricultural Businesses

Agriculture and aquaculture have common features associated with their biological nature affecting risk exposure of the businesses. The aim of this paper is to compare risk exposure in salmon farming and agricultural enterprises in Norway by using an implicit error component model to examine the risk structure of yields, prices and economic returns at the farm level. Results indicate a higher farm-level year-to-year variability in yields, prices and economic returns in salmon farming than in agricultural enterprises. The variability in livestock enterprises was generally lower than for crop enterprises. Return on assets was highest in salmon farming with an average annual return of 9.2%. All of the agricultural farm types exhibited a negative average return on assets on average. Stochastic dominance tests of the distribution of economic returns from aquaculture and agricultural farm types showed salmon farming to be the most risk efficient alternative and salmon farming was most attractive from an investor’s perspective.Risk analysis, variability, Norway, Risk and Uncertainty,

Natural Resource Industries, ‘Tragedy of the Commons’ and the Case of Chilean Salmon Farming

Chilean salmon farming has been considered as an outstanding example of success after growing at double digit rates for more than twenty years. While the expansion was indeed dramatic, it came at the expense of severe sanitary and environmental deterioration. The outbreak in 2008 of the infectious salmon anaemia, a viral disease that kills salmon, but does not affect humans, has made this utterly clear. The overexploitation of the ‘commons’ upon which the industry has grown and the lack of an adequate regulatory mechanism to monitor adverse environmental effects contributed to this disaster, which now threatens the future of the industry and the country benefiting from its natural comparative advantage for salmon farming. The paper shows that activities based on the exploitation of a common pool resource require quite a different analytical approach than the one conventional neoclassical theory offers us for the understanding of firm and industry behaviour. This study shows that industries of this sort enjoy unique location-specific conditions requiring specific know how, R&D, and strong public-private cooperation in order to attain environmentally sustainable long term growth.- Chilean salmon farming, common pool resources, natural resource based industry, ‘tragedy of the commons’

The market for salmon futures: an empirical analysis of fish pool using the Schwartz multifactor model

Using the popular Schwartz 97 two-factor approach, we study future contracts written on fresh farmed salmon, which have been actively traded at the Fish Pool Market in Norway since 2006. This approach features a stochastic convenience yield for the salmon spot price. We connect this approach with the classical literature on fish-farming and aquaculture using first principles, starting by modeling the aggregate salmon farming production process and modeling the demand using a Cobb-Douglas utility function for a representative consumer. The model is estimated by means of Kalman filtering, using a rich data set of contracts with different maturities traded at Fish Pool between 12/06/2006 and 22/03/2012. The results are then discussed in the context of other commodity markets, specifically live cattle which acts as a substitute

The Price Responsiveness of Salmon Supply in the Short and Long Run

Productivity growth and competitiveness indicate that salmon supply is price responsive. However, in the short run supply is likely to be constrained by the biological production process, regulations, and capacity constraints. In this article, we estimate a restricted profit function for Norwegian salmon producers, which allows us to examine the industry’s short-run and long-run supply responsiveness separately. Using data spanning 1985 to 2004, we find that there is close to zero, own-price supply responsiveness in the short run. In the long run, this changes substantially as supply becomes elastic. This result can contribute to explaining the observed cyclical profitability in the salmon farming industry.Restricted profit function, supply, salmon farming, profit cycles, Demand and Price Analysis, Productivity Analysis, Research and Development/Tech Change/Emerging Technologies, Research Methods/ Statistical Methods, D24, Q21, Q22,

Environmental DNA for assessing abundance of salmon lice (Lepeophtheirus salmonis) in salmon (Salmo salar) farms

The aim of this thesis was to investigate an alternative way to detect salmon lice (Lepeophtheirus salmonis) in the field, and investigate the possibility of counting salmon lice in a commercial farming facility of Atlantic salmon (Salmo salar) by using methods and tools based on environmental DNA (henceforth referred to as eDNA). This was performed by sampling water in a salmon farming facility over a couple of months, collecting live salmon lice at a local salmon slaughter factory and conducting an experiment in a laboratory under a controlled environment

The Effect of Color on Consumer WTP for Farmed Salmon

Atlantic salmon is recognized for its pink-red color. The color is due to deposition of color pigments in the muscles. Wild salmon absorb the pink-red color pigment astaxanthin from the crustaceans they eat. To impart the pink-red color in farmed salmon, synthetically produced astaxanthin is added to their feed. The more astaxanthin, the redder the flesh becomes. In conventional salmon farming, the relatively expensive astaxanthin constitutes approximately 15% of the total feed costs. In this study, we use a stated choice experiment with pictures to investigate consumer willingness to pay (WTP) for salmon with different degrees of redness. The results show that consumer WTP increases with the redness of the salmon. However, when consumers were informed about the origin of the color, the WTP for the above-normal-red salmon was reduced.choice experiment, color, mixed logit, salmon, WTP, Resource /Energy Economics and Policy, Q13, Q22,

The Value of Information in Salmon Farming: Harvesting the Right Fish to the Right Time

Research regarding management practice in fish farming has traditionally focused on two topics: production planning and forecasting of prices. This article combine these two areas of research, and illustrate how information of price patterns can change production plans, and hence increase the value of the farm enterprise. We present a model farm and illustrate with different levels of price information how information of future prices alter the original production plan and hence create extra value for the farmer. The phrasing of the paper and the empirical application are on salmon and salmon farming, but the ideas and general results should be applicable to all farmed species.Resource /Energy Economics and Policy,
