Interim report on the progress of an inventory of artesian wells in Florida: leading to the enforcement of sections 370.051 - 370.54, Florida statues

One of the causes of lower artesian pressure, water waste and aquifer contamination is the misuse and insufficient care of artesian wells. In 1953, Senate Bill No. 57, entitled "An Act to Protect and Control the Artesian Waters of the State" (see Appendix) became a law. This law was passed through the efforts exerted by leading members of the Senate and the House of Representatives, who understood the need for a wise and controlled expenditure of our most valuable natural resource. The State Geologist and his authorized representatives were designated by this law to enforce this conservation measure; however, no financial provision was included for the 1953-55 biennium. The proposed program of the Florida Geological Survey for this biennium did not include the funds nor provide any full-time personnel for the enforcement of this statute. As a result, little actual work was accomplished during these two years, although much time was given to planning and discussion of the problem. Realizing that this program could provide additional basic data needed in the analysis of the water-supply problem, the State Geologist sought and was granted by the 1955 Legislature adequate funds with which to activate the first phase of the enforcement of Florida Statute No. 370.051-054. Enumerated below is a summary of the progress made on this investigation as outlined previously: 1. Data have been collected on 967 wildly flowing wells in 22 counties. 2. Chloride determinations have been run on 850 of the 967 wells. 3. Of the 967 wells, 554 have chlorides in excess of the 250 ppm, the upper limit assigned by the State Board of Health for public consumption. 4. Water escapes at the rate of 37, 762 gallons per minute from these 967 wells. This amounts to 54, 377, 280 gallons per day. The investigation is incomplete at this time; therefore, no final conclusions can be reached. However, from data already collected, the following recommendations are proposed: 1. That the present inventory of wildly flowing wells be completed for the entire State. 2. That the current inventory of wildly flowing wells be expanded at the conclusion of the present inventory to include all flowing wells. 3. That a complete statewide inventory program be established and conducted in cooperation with the Ground Water Branchof the U.S. Geological Survey. 4. That the enforcement functions as set down in Sections 370.051/.054, Florida Statutes, be separated from the program to collect water-resource data and that these functions be given to the Water Resources Department, if such is created (to be recommended by the Water Resources Study Commission in a water policy law presented to the 1957 Legislature). 5. That the research phase (well inventory) of the program remain under the direction of the Florida Geological Survey. (PDF contains 204 pages.)

Fecundity of the anchoveta (Cetengraulis mysticetus) in the Gulf of Panama

ENGLISH: One aspect of the work of the Inter-American Tropical Tuna Commission is to investigate the biology, life history, and ecology of the anchoveta (Cetengraulis mysticetus) to make possible an understanding of the effects of the fishery on this species. While the catch per standard day's baiting has been used as a measure of the apparent abundance of anchovetas in the Gulf of Panama (Alverson and Shimada, 1957), it would be desirable to have an independent measure of population abundance. One such estimate can be obtained by a knowledge of the fecundity and sex ratio, together with the total annual egg production of this species. This method is one of those used routinely by the U. S. Bureau of Commercial Fisheries to estimate the size of the spawning population of the Pacific sardine, Sardinops caerulea (California Cooperative Research Program, Progress Report, 1 January 1951 to 30 June 1952). While the purpose of the present paper is to provide information about the fecundity of the anchoveta, nothing is known yet of the total annual egg production of this species although Simpson (1959) has provided much of the information (identification of the anchoveta egg, time of spawning, delimitation of the spawning area) which would be necessary as a basis for enumerating anchoveta eggs in the spawning area of the Gulf of Panama. SPANISH: Un aspecto del trabajo de la Comisión Interamericana del Atún Tropical es la investigación de la biología, historia natural y ecología de la anchoveta (Cetengraulis mysticetus) para que sea posible entender los efectos de la pesquería sobre esta especie. Aunque se ha venido usando la pesca de carnada por día estándar de actividad como una medida de la abundancia aparente de las anchovetas en el Golfo de Panamá (Alverson y Shimada, 1957), sería deseable tener una medida independiente de la abundancia de la población. Una estimación de esta naturaleza puede obtenerse por el conocimiento de la fecundidad de la razón de los sexos, junto con la producción total anual de huevos de esta especie. Este método es uno de los empleados rutinariamente por el Bureau of Commercial Fisheries de los Estados Unidos para estimar el tamaño de la población reproductora de la sardina del Pacífico, Sardinops caerulea (California Cooperative Research Program, Progress Report, 1 January 1951 to 30 June 1952). Aunque el propósito del presente trabajo es el de proveer información sobre la fecundidad de la anchoveta, nada se sabe todavía sobre la producción total anual de huevos de esta especie, a pesar de que Simpson (1959) ha proporcionado abundante información identificación del huevo de la anchoveta, tiempo del desove, delimitación de las áreas de desove) necesaria como una base para medir la producción de huevos de la anchoveta en el área de desove del Golfo de Panamá.

Historia de la piscicultura del pejerrey en Chascomús

El pejerrey Odontesthes bonariensis es uno de los peces de aguas continentales más emblemáticos de la Argentina y una de las especies más estudiada desde diferentes aspectos: ecológico, sistemático, morfológico, fisiológico, genético, etc. (López et al. 1991). Durante los años 1891 y 1892 se realizaron las primeras experiencias de piscicultura,lográndose por primera vez la reproducción artificial en 1904. Su amplia distribución actual es consecuencia de las siembras que se realizaron desde el antiguo Vivero de Piscicultura del Ministerio de Agricultura y Ganadería de la Nación y de la Estación Hidrobiológica del Ministerio de Asuntos Agrarios de la provincia de Buenos Aires, ambos establecimientos ubicados en la ciudad de Chascomús. En el presente trabajo se realiza una aproximación a la historia de la piscicultura del pejerrey en Chascomús, la que se divide en tres períodos: 1) Antecedentes de piscicultura, importancia de la pesca comercial en el sistema de lagunas Encadenadas de Chascomús y primeras medidas tomadas para conservar la explotación de las lagunas hacia fines del siglo XIX. 2) Etapa del antiguo Vivero (Ministerio de Agricultura de la Nación), desde 1904 hasta 1939. 3) Etapa de la Estación Hidrobiológica (Ministerio de Asuntos Agrarios, provincia de Buenos Aires), desde 1943 hasta el presente.

Contribution to the biology and geographical distribution of Aegagropila sauteri (Nees) Kutz. [Translation of: Gidrobiologicheskie Zhurnal, Kiev 4(3), 68-69, 1967]

Aegagropila sauteri is a peculiar green algae, the branched thalli of which, according to the amount of growth, forms velvety spheres of a diameter of 3-4, sometimes to 5-6 cm. and bigger. Investigators attribute it to a special genus of green algae. The authors examine Aegagropila sauteri in Lake Markakol (Kazakhstan).
