(Murcia: Universidad de Murcia, Servicio de Publicaciones, 1986) Más Hernández, J.; Facultad de Biología
A study has been camed out on the distribution, during different periods of time, of the species of the ichthyofauna of the Segura basin. This contribution consists of a superficial preliminary section related to historical antecedents, to give a general perspective from the 16th to 19th centuries. It is followed by a biogeographical description of the position of the watershed in relation to the lberian Peninsula, and a summary of bibliographical information from 1930 to 1952. Finally, there is a description of the present situation. Some faunal characteristics have been analysed, detailing the date and magnitude of the repopulations and introductions into the ecosystem. This has been complemented with some considerations on the recent evolution of the fish population and on the possibilities of recuperation in the immediate future.
