Abstract
  • The aim of this work is to estimate the supply elasticity of the fish regarding the variationsin one of the most important running costs (fuel cost) for the Galician fleet in the Celtic Sea. The Spanish fleet involved in the Celtic Sea fishing grounds, also known as the _300 fleet_, as when Spain joined the EEC it was made up of this number of vessels, presently has 199 vessels (the 70% of them operate from Galicia).This fleet mainly catches hake (merlucius merlucius), anglerfish (Lophius piscatorius and Lophius budegassa), horse mackerel (trauchurus trauchurus), megrim (Lepidorhombus whiffiagonis) and nephrops. Although it is currently possible to associate specific target species with particular fleets, various quantities of hake, anglerfish, megrim and nephrops are taken together, depending on the gear type. A supply function for each species has been estimated as an expression that depends on the price of fish, price of other fish landed by the fleet and the fuel price. The preliminary results indicate that the supply of some species is more elastic regarding the fluctuations in fuel prices than other ones. It could explain the strategy of the fleet for selecting the less elastic stocks to the fuel costs.
