Distribution and Apparent Abundance of the Basking Shark, Cetorhinus maximus, off the Central and Southern California Coast, 1962-85

Basking sharks, Cetorhinus maximus, are frequently observed along the central and northwestern southern California coast during the winter and spring months. These large plankton feeding elasmobranchs, second in size only to the whale shark, Rhineodon typus, had been the subject of a small commercial fishery off California in the late 1940's and early 1950's for their liver oil, rich in vitamin A, and in later years for reduction into fish meal and oil (Roedel and Ripley, 1950). These fisheries were sporadic and did not take basking sharks in large numbers.

Eleventh Annual Report for the year ended 31st March, 1962

This is the eleventh Annual report of the Cumberland River Board on information of its activities and responsibilities on river management in its area between the beginning of April 1961, to the end of March 1962. The report contains 5 main sections on water resources, land drainage, fisheries, pollution, and finally the expenditure and income for the 12 month period. The first area that the report deals with is water resources, which includes information on the building of gauging stations, abstraction of water, and rainfall and river flow. The section on land drainage looks at work on improvement schemes and information on maintenance work carried out on rivers including Wampool, Waver, Wiza, Ellen, Cocker, Irt, Mite, Keekle, Eden, Esk, Caldew and Petteril. The fisheries section covers 5 districts of the River Eden, Esk, Derwent, Ellen and South West Cumberland. It includes angling information and a general report for salmon and sea trout, Brown trout and freshwater fish. Fish disease and fish hatchery are also covered as well as Byelaws and fisheries protection. The fourth section on pollution deals with water quality and information on sewage and trade effluents. The River Boards preceded the Environment Agency which came into existence in 1996.

River Dart Scale Reading Investigation Report on the 1962 Season

This is the first River Dart Scale Reading Investigation Report on the 1962 season by the Devon River Board. The object of this investigation is to examine, by means of scale-reading, the general biology of the salmon population of the River Dart. It reviews briefly the theory and mechanics of the scale-reading technique, the life history of the salmon, and the methods used for the collection of scales and the examination of the materials. It shows the results of the survey and the number of scales studied from each of the various sea-age classes, time of running with distribution of the sea-age groups throughout the season, fish sizes and smolt ages at migration. All are summarized in various tables and figures are also included, plotting weight distributions for each age classes and frequency distributions.

Fisheries Survey River Avon, 1962

This is the Fisheries Survey River Avon, 1962 by the Devon River Board. The object of the survey is to investigate the present distribution and relative abundance of salmonid fish in the river. It describes the methods of the investigation, the sampling and identification. It goes through the salmon, sea-trout and brown trout parrs, adult and coarse fish frequencies and distributions, all summarized in individual tables for each fish class. It also includes a variety of comments about the obtained results.

Ictiólogos de la Argentina: Aurelio Juan Santiago Pozzi

This series will include all those people who, by means of their contributions, great and small, played a part in the consolidation of ichthyology in Argentina. The general plan of this work consists of individual factsheets containing a list of works by each author, along with reference bibliography and, whenever possible, personal pictures and additional material. The datasheets will be published primarily in chronological order, although this is subject to change by the availability of materials for successive editions. This work represents another approach for the recovery and revalorization of those who set the foundations of Argentine ichthyology while in diverse historical circumstances. I expect this to be the beginning of a major work that achieves the description of such a significant part of the history of natural sciences in Argentina.

Lista de los peces de la provincia de Santiago del Estero.

Esta serie tiene como finalidad dar a conocer las especies presentes en los diferentes estados provinciales. Tomando como base los trabajos de López et al. (2003), Reis et al. (2003) y Liotta (2006), mencionamos para cada territorio los cambios y novedades posteriores a estas publicaciones. Además, las especies introducidas son señaladas en las tablas I y II. Consideramos que este modesto aporte contribuirá a precisar el conocimiento ictiofaunístico regional, ya que, además de las listas de especies, adjuntamos bibliografía de referencia y el marco biogeográfico e hídrico correspondientes, que podrán ser de utilidad para quienes hagan uso de este trabajo. Por otra parte entendemos que la participación de autores involucrados en la región considerada, le da un verdadero sentido federal a esta contribución, además de reforzar vínculos en los protagonistas de nuestra especialidad. En este nuevo número presentamos la provincia de Santiago del Estero que se encuentra limitada al noroeste por Salta, al norte y noreste por Chaco, al sudeste por Santa Fe, al sur por Córdoba y al oeste por Catamarca y Tucumán. A las 39 especies citadas por Liotta 2006 para la provincia de Santiago del Estero debemos agregar 2 citas, de las cuales 1 es introducida (Tabla II). En el listado no están incluidas 8 especies que requieren confirmación (Tabla III).

El plancton de Mar del Plata durante el período 1961-1962 (Buenos Aires, Argentina)

The first part presents a general picture of the composition of the coastal plankton near Mar del Plata (Buenos Aires prov., Argentina) between August 1961-August 1962. Especially noted is the abundance of Noctiluca from October to the end of March. The second part deals with the plankton collected during a short cruise, named Operación Mar del Plata 1, planned to survey coastal waters. In the third part the author gives the descriptions of some new or interesting species. A chain-forming Gymnodinium is reported as G. catenatum; some differences with Graham description, could be due to the fact that he studied only preserved material. Oblea baculifera is a new species belonging to the new genus Oblea, of the Diplopsalis group, created for some species previ¬ously known as Peridiniopsis. A key of the included species is given. The other new species are Peridinium aspidiotum, P. anomaloplaxum, P. lipopodium and Gonyaulax fratercula, all of them carefully described and depicted. Sticholonche zanclea (Radiolaria), Calsiosolenia sinuosa (Coccolithophoridae) and Tintinnopsis levigata (Tintinnida) are reported for the first time in the South-Atlantic. For T. levigata ?, Balech, 1939, a new name has been created: T. tregouboffi. Some unknown details of the protoplasm of the silicoflagellate Dictyocha octonaria are described. In the fourth part the author compares the plankton taken in Mar del Plata with the previously studied at Pto. Quequén. The plankton of March-April points to an invasion of oceanic warm waters from the Brazilian Current System.
