Geographical distribution of yellowfin and skipjack tuna catches in the Eastern Pacific Ocean, and fleet and total catch statistics, 1975-1978

ENGLISH: Logbook records of purse seiners and baitboats fishing for yellowfin and skipjack tunas in the eastern Pacific Ocean were used to prepare charts showing the distribution of catches by one-degree area and quarter of the year for each gear and regulation status, for the years 1975-1978. Changes in geographical distribution of the catch over the four-year period are described. Information on annual catch statistics and fleet composition by country is presented. SPANISH: Se emplearon los registros de bitácora de las embarcaciones cerqueras y de carnada que pescan atún aleta amarilla y barrilete en el Océano Pacífico oriental, para preparar los diagramas que indican la distribución de captura por zonas de un grado y trimestres del año de cada arte y condición de las reglamentaciones, en los años de 19'75 a 1978. Se describen los cambios de la distribución geográfica de la captura durante un período de cuatro Se presenta la información, por país, de las estadísticas de captura y de la composición de la flota.

Culturable fish seeds in Nigerian waters: A research survey (1978-1985)

The desired species identified in this survey include mullets, catfishes, fast growing fish predators, species for control of weeds and grass it, ponds, cichlids and shrimps. Five coastal states: Lagos, Ondo, Bendel, Rivers, and Cross River were covered in the studies. Investigations were also carried into the major rivers and their tributaries. A combination of the estimation methods of Le Cren, (1962) and Pitcher and Mac Donald (1973) was employed in the analysis of data. From the detailed data collected from (1978-1985), the survey indicated that about 100 million fish seeds can be collected annually from Nigerian waters using appropriate gear-seine nets, cast nets, and fish traps. Of this number, 60% is available along the coastal belt of the country while 40% is in the major rivers, their tributaries and swamps. At the present level of fish culture development in Nigeria, this is more than enough, even after allowing for 50% mortality due to handling and transportation stress

Report on the electrophoretic and morphometric studies conducted at the Inter-American Tropical Tuna Commission from 1969 to 1978

Knowledge of the population structure of an exploited stock is necessary for the effective management of a fishery. For this reason the Inter-American Tropical Tuna Commission (IATTC) has sponsored numerous genetic, morphometric, and migration studies of yellowfin, Thunnus albacares, and skipjack, Katswonus pelamis, in a concerted effort to determine the structure of these stocks in the eastern Pacific Ocean.

Some data on landings of pelagic fish by the artisanal fishermen near Freetown during January-December 1978

Pelagic fish (except for tuna) are landed in Sierra Leone mainly by the artisanal fishermen. The two most important species are Sardinella and Ethmalosa.Deep-sea species are normally exploited by purse seiners of foreign countries. The landings of artisanal fishermen largely comprise Sardinella eba.Landing data for Sardinella landed at Tombo and Goderich, and for Ethmalosa at Tombo, are presented in tabular form. Collection methods are described, with a definition of the unit of fishing effort, and a description of the gear used.The landing data are discussed with particular attention to fishing effort, catch per unit effort, and price per ton

An identification key of the most important German freshwater teleost fishes by means of their eggs [Translation from: Archiv fur Hydrobiologie 83(2), 200-212, 1978]

The fetal and larval development of many freshwater fish is already relatively well covered. Coverage of the morphology of fish-species' eggs is very sparse. For this reason the authors have attempted to prepare a key on fish eggs which covers the bulk of German Teleostei fish. The key also includes a discussion of problems of categorization and terminology.

Respiration and the efficiency of energy during embryonic development of Asellus aquaticus L. (Crustacea) [Translation from: Vestsi Akademii Navuk Belorusskoi SSR, Seriya Biyal. 1978(5) 112-114, 1978]

Experimental studies were carried out on the transformation of matter and energy during embryonic development of the isopod Crustacea Asellus aquaticus L. under two constant temperatures. Material for the experiments was collected in the quarry lakes of the Kurasovshchin-zone (city-Minsk) at 9°C in April and at 18°C in June, 1977. The rate of consumption of oxygen per specimen by eggs and embryos of Asellus aquaticus was observed and dynamics of the basic biological characteristics during embryonic development studied.

The intensity of photosynthesis in salt lakes of Crimea [Translation from: Informatsionnyi Byulleten Biologiya Vnutrennikh Vod No.37 26-29, 1978]

The purpose of this work was the study of phytoplankton production of the salt lakes of the Steppe region of Crimea, during the vegetative period of 1974. From May to October Sakskoe and Sasyk Lakes were examined, and from August to October - Moinakskoe Lake. The density of the salt water was measured and the intensity of photosynthesis was determined. From the data presented, it is apparent that the intensity of photosynthesis in Sakskoe and Sasyk Lakes, on average, is extremely high.

Report of the Inter-American Tropical Tuna Commission for the year 1978

ENGLISH: The Inter-American Tropical Tuna Commission operates under the authority and direction of a convention originally entered into by the Republic of Costa Rica and the United States of America. The convention, which came into force in 1950, is open to adherence by other governments whose nationals fish for tropical tunas in the eastern Pacific Ocean. Under this provision the Republic of Panama adhered in 1953, the Republic of Ecuador in 1961, the United Mexican States in 1964, Canada in 1968 and Japan in 1970. In 1967, Ecuador gave notice of her intent to withdraw from the Commission, and her withdrawal became effective on August 21,1968. The Commission held two meetings in 1977, the 34th from June 27 to 29 in San Diego, California, and the 35th on October 17 and 18 in Mexico City. The Commission adjourned its 35th meeting, held in Mexico City on October 17, and 18, 1977, without agreeing to a resolution for the conservation of yellowfin during 1978. SPANISH: La Comisión Interamericana del Atún Tropical está bajo la autoridad y dirección de una convención la cual fue originalmente formada por la República de Costa Rica y los Estados Unidos de América. La Convención, vigente desde 1950, está abierta a la afiliación de otros gobiernos cuyos nacionales pesquen atún en el Pacífico oriental tropical. Bajo esta medida la República de Panamá se afilió en 1953, la República del Ecuador en 1961, los Estados Unidos Mexicanos en 1964, Canadá en 1968 y el Japón en 1970. En 1967, el Ecuador anunció su intención de retirarse de la Comisión y la renuncia se hizo efectiva el 21 de agosto de 1968. La Comisión celebró dos reuniones en 1977, la XXXIV del 27 al 29 de junio en San Diego (California) y la XXXV del 17 al 18 de octubre en ciudad de México. La Comisión clausuró su XXXV reunión, celebrada en ciudad de México del 17 al 18 de octubre de 1977, sin acordar una resolución para la conservación del atún aleta amarilla en 1978.
