A recent study in agricultural products has brought out evidence of asymmetrical transmission of price changes according to the sign (positive or negative) of past variation. Interestingly, asymmetry was more commonplace for products with a lower elasticity of supply due to the perishable nature of products. A similar study based on TAR and M-TAR cointegration models is carried out on the French markets for fish products. In particular, this paper investigates the relation between the characteristics of supply (farmed or wild-caught species) and the results regarding asymmetry of price transmission along the supply chain of fresh products. Like in previous studies, it is expected that farming, by increasing the security of supply, show less asymmetry than wild-caught products. Results bring no evidence of asymmetric price transmission in any avlue chain, whatever the origin of the supply, farmed or wild. It is nevertheless found differences in terms of speed of adjustment and size of margins taht can be interpreted as a consequence of the uncertainty in the conditions of supply. ...French Abstract : Des travaux en économie agricole ont récemment montré que le caractère asymétrique de la transmission des prix le long d'une filière apparaissait fréquemment pour des produits avec une faible élasticité de l'offre due au caractère périssable de ces produits. Un travail similaire utilisant des modèles de cointégration de type TAR et MTAR, est ici effectué pour des produits de la pêche. Plus précisément, ce travail recherche s'il existe une relation entre le type d'asymétrie mis en évidence et les caractéristiques du produit étudié : espèce sauvage ou espèce d'élevage. L'hypothèse testée est que les produits provenant d'élevage sont caractérisés par une transmission asymétrique moindre ampleur que les produits sauvages, l'élevage permettant de réduire les incertitudes quant à l'offre. Les résultats empiriques n'apportent aucune validation de cette hypothèse. Néanmoins, ils mettent en évidence une forte différence quant aux vitesses d'ajustement à court terme qui peuvent être interprétées comme une conséquence de l'incertitude dans les conditions d'offre des produits sauvages.
