Introducción de peces exóticos en la República Argentina

A review and analysis of the exotic fish distribution and introduction is made using bibliographic information. Both lentic and lotic environments were considered. In order to classify the state of the populations, different categories were defined as follow: permanent, probably permanent, reported and unknown. Results show that 15 species were attempted to be introduced from 1904. Only 8 of them arose an successfull aclimatization: raimbow trout, brown trout, lake trout, landlocked salmon, carp, goldfish, and mosquitofish. For the salmonids, ecological features were analized, in order to explain the disappearence or the permanence in some regions. (Document contains 90 pages)

Evaluación del rendimiento pesquero potencial de la República Argentina: I. Datos 1

A limnological and fish survey program was developed on 110 lakes and reservoirs of Argentina during the summers of 1984 to 1987. Here we exclude lakes without fish. Lakes and reservoirs were visited once each, except for six situated in Chubut Province that were studied seasonally over the course of two years. Here we present raw data used to evaluate the potential fish yield of Argentinian lakes and reservoirs. (Document contains 56 pages.)

Evaluación del rendimiento pesquero potencial de la República Argentina: II. Evaluación por regiones

A limnological and fish survey program was developed in 110 lakes and reservoirs of Argentina during the summers of 1984 to 1987. Lakes and reservoirs were visited once, except for six situated in the Chubut Province that were studied seasonally over the course of two years. The sampling surveys were performed by the "Instituto Nacional de Investigación y Desarrollo Pesquero" and the "Provincia de Chubut". Here we present preliminary results of potential fish yield assessment on a regional basis, using empirical models. (Document contains 11 pages.)

Evaluación del rendimiento pesquero potencial de la República Argentina: III. Edad y crecimiento de peces 1

Age and growth of populations of three fish species from sixteen lakes and reservoirs situated in the Patagonian Andean and the Patagonian Plateau Region (Argentina) were studied. They included two native species, the Patagonian smallmouth perch. (Percichthys trucha) and the Patagonian silverside (Patagonina hatcheri) and the introduced rainbow trout (Oncorhynchus mykiss). For the three species backcalculated lenght at age was obtained from scale readings. Von Bertalanffy growth curves were usually adjusted to data. For the three species, faster growth was related with lake productivity. (Document contains 38 pages.)

Nuevas localidades para peces de agua dulce de la República Argentina. I.

Four species of Characiformes and five species of Siluriformes are recorded from ten new argentine localities. New distributional data are discussed. Relevant morphological measurements and some comments are added.
