RT Journal Article T1 Investment and Decapitalization in the Fishing Industry: The Case of the Spanish Crustacean Freezer Trawler Fleet A1 González Galán, Ana A1 García del Hoyo, Juan José A1 García Ordaz, Félix AB The objective of this work is to estimate the capital stock invested in the Spanish freezertrawler fleet dedicated to the capture of crustaceans on the African coast, for the period from 1964 to2019. The importance of having methods for the correct measurement of the capital invested in afishing fleet is to be able to express in monetary terms the excess catch capacity, which is a signal ofoverexploitation of a fishery, that is, the fleet operates at a level of effort or capacity higher than theminimum amount required to capture the desired quantity at the lowest possible cost. Followinga methodology based on the permanent inventory method, we obtained a model that explains theconstruction value of a fishing vessel as a function of its technical characteristics. The market valuein successive sales was estimated as a function of the construction value, the age of vessel and othervariables. In this way, we estimated the value that the market assigns to the possible increases inindividual fishing capacity and the decrease in value derived from the technical obsolescence of thevessels. Finally, we calculated the gross and net investment series and net capital stock PB MDPI SN 2071-1050 (electrónico) YR 2021 FD 2021 LK http://hdl.handle.net/10272/20288 UL http://hdl.handle.net/10272/20288 LA eng NO González Galán, A., García del Hoyo, J.
