Ground water in the Immokalee area, Collier County, Florida

The scope of the investigation involved the drilling of test holes and the detailed inventorying of existing wells in order to define the location, depth, potential yield, and chemical quality of the water contained in the shallow aquifer that might be used for the development of a central water-supply system. The field work and collection of data for the investigation covered the period 1961 through 1963. Much of the data collected for the report on the ground-water resources of Collier County (McCoy, 1962) is incorporated into this report. (Document has 36 pages.)

Report of the Inter-American Tropical Tuna Commission for the year 1962

ENGLISH: The Inter-American Tropical Tuna Commission, pursuant to the provisions of the Convention, has the duty of collecting and interpreting factual information to facilitate maintaining the populations of tunas, and of tuna baitfishes, supporting the fisheries pursued by nationals of its Member Governments in the Eastern Pacific Ocean, at levels which will permit maximum sustainable average harvests year after year. This requires a wide variety of research into the biology, life history, ecology and population dynamics of the several species, and investigations into the effects of both natural factors and fishing activity on their abundance and on the harvests they can sustain. The research is conducted by a permanent, internationally recruited scientific staff, employed directly by the Commission, selected on the basis of professional competence by the Director of Investigations. SPANISH: La Comisión Interan1ericana del Atún Tropical, de informidad con las disposiciones de la Convención, tiene el deber de recolectar e interpretar la información que facilite el mantenimiento de las poblaciones del atún y de los peces de carnada que sirven para la pesca de este, sosteniendo las pesquerías a que se dedican los habitantes de sus Gobiernos Miembros en el Océano Pacifico Oriental, a niveles ,de abundancia que permitan un promedio máximo sostenible de cosechas ano tras ano. Esto requiere una amplia variedad de investigaciones dentro de la biología, historia natural, ecología y dinámica de las poblaciones de diversas especies, y sabre los efectos, tanto de los factores naturales como de la actividad pesquera, en la abundancia de las mismas y en el rendimiento que puedan dar. La investigación es conducida por un grupo científico permanente, cuyos miembros son reclutados internacionalmente empleados directamente por la Comisión, una vez que han sido seleccionados sobre la base de su competencia profesional, por el Director de Investigaciones.

The influence of blue-green algae on development of the zooplankton. [Translation of: Byull.mosk.Obshch.Ispyt.Prir.(Biol.) 67, 128-131, 1962]

Many have observed the reduction of the quantity of zooplankton in the presence of water blooms. It is known that in seas zooplankton as it were avoids places of accumulation of blue-green algae. By observations on one of the tributaries of the Rybinsk reservoir - the River Shumorovka - the authors tried by simultaneous collections to trace the changes in numbers, not only of zoo- and phytoplankton but also of bacteria. The plankton was collected by quantitative nets with suitable numbers of gauze and bacteria were taken account of by the method of direct calculation on membrane filters. It can be seen that the development of blue-green algae appears as an important factor, determining not only the intensity but also the direction of the process of production of zooplankton.

A contribution to the knowledge of the skin albuminose cells of Torpedo ocellata Raf [Riv.Istochim.norm.pat. 8 411-416, 1962]

Glandular cells, other than the mucous cells, have been described in the skin of various groups of fish (Teleosts, Ganoids, Selachii) and they have been called 'albuminose' by various authors. The authors propose to study the albuminose cells in the skin of Torpedo ocellata Raf. from a histochemical point of view. The albuminose cells have a complex morphological structure and a correspondingly complicated histochemical make-up. One must treat them as an example of cell with secretions of a particular type, which must and will be better incorporated when more is known of characteristics existent in other species.

Experimental culture of algal balls (Cladophora sauteri). Retention of original shape [Translation from: Bull.Jap.Soc.Phycol. Vol. 10, (1), p. 23-27, 1962]

It was on July 1960 when 10 algal balls were acquired for exhibition at Suma Aquarium, Kobe. Permission to remove the specimens from the Lake Akan Reserve was given by the National Nature Reserve Committee. Algal balls, as a rule, lose their natural beauty when they are kept in an ordinary tank for a certain length of time. In an effort to retain the natural beauty it was decided to exhibit them in culture. This paper summarises the findings of this experiments with Cladophora sauteri. The author concludes that serious consideration has to be given as to the intensity of light, the sunlight, the water temperature and the nutrition for algal balls in culture in order to retain the natural beauty and shape.
