Bibliografía de los peces de agua dulce de Argentina. Suplemento 1993.

La presente lista constituye un nuevo aporte a la información de los peces de agua dulce de la Argentina (López et al., 1981, 1982, 1986 y 1989). Por razones de economía de espacio, hemos variado el esquema seguido en las anteriores, no mencionamos los resúmenes de las diferentes reuniones, ni las especies citadas en el texto de los trabajos incluidos. Por otra parte, no consideramos las contribuciones de nuestros colegas uruguayos (con excepción de aquellas referidas a cuerpos de agua compartidos), ya que temimos caer en olvidos involuntarios que, con el tiempo, se transformen en situaciones enojosas.

Sampling and analytical methods of the National Status and Trends Program Mussel Watch Project: 1993-1996 Update

Polycyclic aromatic hydrocarbons, butyltins, polychlorinated biphenyls, DDT and metabolites, other chlorinated pesticides, trace and major elements, and a number of measures of contaminant effects are quantified in bivalves and sediments collected as part of the NOAA National Status and Trends (NS&T) Program. This document contains descriptions of some of the sampling and analytical protocols used by NS&T contract laboratories from 1993 through 1996. (PDF contains 257 pages)

Biology and Management of Sablefish, Anoplopoma fimbria: Papers from the International Symposium on the Biology and Management of Sablefish, Seattle, Washington, 13-15 April 1993

At its june 1990 annual meeting, the Technical Subcommittee (TSC) of the Canada-U.S. Groundfish Committee recommended that scientists and managers working on sablefish, Anoplopoma fimbria, issues convene to present and discuss the results of their recent research. Thorough knowledge of the biology and population dynamics of this species is essential for its effective management, especially considering its commercial importance. TSC representatives from both countries recognized that a great deal ofactive research has been conducted on this species since the International Sablefish Symposium was held in Anchorage, Alaska, in March 1983 (Melteff, 1983). As a result of this recommendation, the International Symposium on the Biology and Management of Sablefish (ISBMS) was convened April 13-15, 1993, at the Alaska Fisheries Science Center in Seattle, Washington.

Ecology of Juvenile Walleye Pollock, Theragra chalcogramma: Papers from the workshop "The Importance of Prerecruit Walleye Pollock to the Bering Sea and North Pacific Ecosystems" Seattle, Washington, 28-30 October 1993

The Alaska Fisheries Science Center (AFSC), National Marine Fisheries Service (NMFS), hosted an international workshop, 'The Importance of Prerecruit Walleye Pollock to the Bering Sea and North Pacific Ecosystems," from 28 to 30 October 1993. This workshop was held in conjunction with the annual International North Pacific Marine Science Organization (PICES) meeting held in Seattle. Nearly 100 representatives from government agencies, universities, and the fishing industry in Canada, Japan, the People's Republic of China, Russia, and the United States took part in the workshop to review and discuss current knowledge on juvenile pollock from the postlarval period to the time they recruit to the fisheries. In addition to its importance to humans as a major commercial species, pollock also serves as a major forage species for many marine fishes, birds, and mammals in the North Pacific region.

Silver King Creek Paiute cutthroat trout restoration, 1991 through 1993

Silver King Creek, Alpine County, is the native range of the Federally-threatened Paiute cutthroat trout, Oncorhynchus clarki seleniris. Paiute cutthroat currently inhabit Coyote Valley and Corral Valley creeks, which are tributaries to Silver King Creek below Llewellyn Falls, and also Silver King Creek and tributaries aboye Llewellyn Falls. Rainbow trout, O. mykiss, were introduced into the basin during 1949 and became hybridized with Paiute cutthroat. Chemical treatments attempted by the California Department of Fish and Game (CDFG) in 1964 and 1976 failed to eliminate hybrid trout. A chemical treatment project was again conducted by the CDFG from 1991 through 1993 to eliminate hybrid trout from within the range of Paiute cutthroat. This report presents a summary of events for the first two years of the Silver King Paiute Cutthroat Trout Restoration Project; a more thorough analysis is made of the third and final year of the project.

Seltene Fischlarven in den Ichthyoplanktonfängen der westlichen Ostsee im Zeitraum 1993 - 1996

Distribution and abundance of fish eggs and larvae in North Sea and Baltic Sea have been objectives of fishery research for over 100 years. Most fish species produce pelagic eggs or larvae. The early developmental stages of many marine fish species important to commercial fishery are part of plankton communities, and can be sampled by a single gear. Collections of fish in their larval phase provide material for studies of many aspects of fishery research: e.g. information on plankton communities and abundance of fish species in the area of investigation.

Oceanographic Profiling and Spectroradiometer Observations from the MOCE-2 Cruise: 28 March to 14 April 1993

This report contains results from the second cruise of the Modis Optical Characterization Experiment (MOCE). Data presented here were obtained on the Mexican Research Vessel El Puma between 29 March and 13 April along the Pacific coast of Baja California and in the Gulf of California. Three types of data are reported: high spectral resolution radiometry at three depths for 13 stations; salinity, temperature beam attenuation and chlorophyll-a fluorescence, profiles at the same stations; and total suspended matter and suspended organic carbon and nitrogen.(PDF is 90 pages.)

Deutsche Rotbarschfischerei im NW-Atlantik (Reykjanes Rücken - Irminger See - Ostgrönlandschelf) in den Jahren 1993 und 1994 und ihre möglichen Zukunftsaussichten

Die Rotbarschfänge der deutschen Hochseefischerei in der Irminger See (ICES Gebiet XII und XIV) weisen in den beiden letzten Jahren, verglichen mit anderen kommerziellen Arten ( z.B. Kabeljau) hohe Steigerungsraten auf. Sie sind einerseits durch die Wiedervereinigung (Eingliederung der damaligen Rostocker Hochseefischerei in die BRD-Flotte), anderseits durch Fangsteigerungen der DFFU (Deutsche Fisch-Fang-Union) auf den historischen Fanggründen des Ostgrönlandschelf bedingt. Über diese Fischereien, sowie über ihre Zukunftsaussichten, soll im Folgenden berichtet werden.

Auswirkungen der Salzeinströme 1993/1994 auf die ozeanographischen Bedingungen in der zentralen Ostsee

The effects of both the major Baltic inflow in January 1993 and two smaller inflows in December 1993 and March 1994 on the environnmental conditions in the Bornholm, Gdansk and eastern Gotland Basins are described. These inflows terminated the 16-year stagnation of the central Baltic deepwater and led to a moderate increase in salinity, but to the highest oxygen concentrations in the Gotland Deep since the 30ies.

Report of the Inter-American Tropical Tuna Commission for the year 1993

ENGLISH: The Inter-American Tropical Tuna Commission (IATTC) operates under the authority and direction of a convention originally entered into by Costa Rica and the United States. The convention, which carne into force in 1950, is open to adherence by other governments whose nationals fish for tropical tunas and tuna-like species in the eastern Pacific Ocean. Under this provision Panama adhered in 1953, Ecuador in 1961, Mexico in 1964, Canada in 1968, Japan in 1970, France and Nicaragua in 1973, Vanuatu in 1990, and Venezuela in 1992. Ecuador withdrew from the IATTC in 1968, Mexico in 1978, Costa Rica in 1979, and Canada in 1984. Costa Rica readhered to the convention in 1989. The Commission held its 51st meeting in Port Vila, Vanuatu, on June 8-10, 1993. SPANISH: La Comisión Interamericana del Atún Tropical (CIAT) funciona bajo la autoridad y dirección de un convenio suscrito originalmente por Costa Rica y los Estados Unidos de América. El convenio, vigente desde 1950, está abierto a la afiliación de cualquier país cuyos ciudadanos pesquen atunes tropicales y especies afines en el Océano Pacífico oriental. Bajo esta estipulación, la República de Panamá se afilió en 1953, Ecuador en 1961, México en 1964, Canadá en 1968, Japón en 1970, Francia y Nicaragua en 1973, Vanuatu en 1990, y Venezuela en 1992. Ecuador se retiró de la CIAT en 1968, México en 1978, Costa Rica en 1979, y Canadá en 1984. Costa Rica se adhirió de nuevo al Convenio en 1989. La Comisión celebró su 51ª reunión en Port Vila (Vanuatu) del 8 al 10 de junio de 1993. (PDF contains 316 pages.)
