“…The growth is a result of substantial productivity growth 1997;Guttormsen, 2002;Tveteras, 2002) that has reduced production costs to about a third of the level in the early 1980s. Furthermore, the growth has been amplified by market growth that at least partly is due to generic marketing programmes (Bjørndal, Salvanes and Andreassen, 1992;Myrland, 2000, 2002).…”

“…The increase in production has been accompanied by declining real prices, primarily because of a substantial productivity growth for farmed salmon (Asche, 1997;Guttormsen, 2002;Tveteras, 2002). However, in addition to the influence of farmed salmon, a number of hypotheses have been forwarded for the causes of price declines for wild salmon.…”

This article examines the Japanese market for salmon. This market is of interest, since it is the largest and most diversified salmon market in the world with wild and farmed species, from Europe and South and North America, competing in the same market. In contrast to the European Union (EU)- and U.S.-markets, there have been neither trade conflicts nor trade restrictions. The Japanese market can hence provide information about the impact of bringing substantial quantities of a new product into a market, and the effect of large-scale aquaculture on traditional fisheries. In this article, market integration between wild and farmed salmon on the Japanese market is examined, using both bivariate and multivariate cointegration analysis. Tests for the Law of One Price are also conducted. The results indicate that the species are close substitutes on the market, and that the expansion of farmed salmon has resulted in price decreases for all salmon species.

“…This is also the case for salmon aquaculture, one of the technologically leading sectors. Our study focuses on salmon aquaculture, which has increased its degree of control with the production process through many innovations in key technologies such as fish feed, feeding equipment, IT based monitoring of live fish, vaccines and genetics [4], [5], [6]. Salmon production has moved from a technological regime with poor degree of control of many processes to one that can be described as approaching 'biological manufacturing'.…”

Abstract. Since the 1980s a large number of innovations have radically transformed the production process in salmon aquaculture. Increased degree of control with the production process, increased scale of plants, and more intensive use of farm locations are some of the consequences. Until the mid 1990s the industry also experienced rapid productivity growth leading to production costs to be reduced to 1/3 of their initial levels in Norwegian salmon aquaculture. But thereafter productivity has been stagnant. This paper analyses the innovation process and productivity growth in the Norwegian salmon industry, and discusses the challenges for the future.

“…A raíz de esto, se ha incorporado una mayor tecnología en equipos y producción de alimentos, en normas y procedimiento en bioseguridad, además de la especialización y capacitación del personal en los centros de cultivo, situación que lleva emparejado un incremento en los costos de producción, que serán más altos en aquellas empresas con menor desarrollo tecnológico (Bjørndal, 2001). Por otra parte, la industria chilena del salmón, no utiliza una estrategia colaborativa, debido a la alta competitividad entre las distintas empresas (Fehlandt & Rodríguez, 2006), situación que no ocurre en Noruega (Tveteras, 2002).…”

RESUMEN. En Chile, la mayoría de las empresas de cultivo de salmones en la fase parr alimentan a los peces con 24 raciones/día; por otra parte, el alimento en el estómago de los peces, puede permanecer cerca de 4 a 5 h. Este trabajo evalúa en base a procedimientos y protocolos productivos, la disminución en la frecuencia de raciones de alimento y su efecto en la supervivencia, crecimiento, conversión y conducta de alimentación de los peces. Se trabajó en condiciones normales de producción comercial, con aproximadamente 1.200.000 peces de 0,17 g durante cuatro meses. Hubo dos tratamientos, el control con 24 raciones/día y el ensayo, que al inicio de la experiencia se entrego 12 raciones/día y al finalizar la experiencia se proporcionó 4 raciones/día. Se emplearon cinco estanques de 18 m 3 para cada tratamiento. La disminución en la frecuencia de alimentación, no afectó la supervivencia de Salmo salar, se obtuvo mayor crecimiento en los peces del ensayo, con mejor conversión de alimento, se logró reducción de alimento depositado en el fondo de los estanques y se visualizó mejor apetito en los peces.

In Chile, most salmon-farming companies feed fish in the parr phase 24 rations/day. However, food can remain in fish stomachs for around four or five hours. Using productive procedures and protocols, this study evaluates less frequent food rations and how they affect the survival, growth, conversion, and feeding behavior of the fish. The study was conducted over four months under normal commercial production conditions, using approximately 1,200,000 fish of 0.17 g each. There were two treatments: the control, which received 24 rations/day, and the assay, which received 12 rations/day at the onset of the study and 4 rations/day at the end of this. Five tanks, each 18 m 3 , were used for each treatment. The lower feeding frequency did not affect the survival of Salmo salar. The fish in the assay obtained greater growth and had better food conversion rates. Less food was deposited on the bottom of the assay tanks, and the fish were observed to have better appetites. Keywords: food ration, growth, feeding behavior, Salmo salar, Atlantic salmon, aquaculture, Chile. ___________________Corresponding author: Héctor Flores (hflores@ucn.cl) INTRODUCCIÓNEn Chile, la salmonicultura ha tenido un crecimiento sostenido durante los últimos años, demostrando su gran capacidad de desarrollo, llegando a ser uno de los principales productores y exportadores de salmón en el mundo. El recurso más cultivado en Chile es salmón del Atlántico (Salmo salar) con una cosecha total de 204.013 ton el año 2009 (SERNAPESCA, 2009), posicionando al país junto a Noruega como los productores más importantes a nivel mundial, con un ...
