Chinook salmon spawner stocks in California's Central Valley, 1989: annual report

This report covers the 37th annual inventory of chinook salman, Oncorhynchus tshawytscha, spawner populations in the Sacramento-San Joaquin River system.-It is a compilation of reports estimating the fall-, winter-, late-fall-, and spring-run salmon spawner populations for streams which were surveyed. Estimates were made from counts of fish entering hatcheries and migrating past dams, froro surveys of dead and live fish and redds on spawning areas, and from aerial counts. The estimated 1989 total escapement of chinook salmon in the Central Valley was 205,990 fish. This total consisted of 181,864 fall-, 12,171 spring-, 539 winter-, and 11,416 late-fall-run spawners. All of the spring-, late-fall-, and winter-run salmon were estimated to be in the Sacramento River system, while 3,493 fish of the fall run were in the San Joaquin River system. Due to decreases of spawner populations in most Central Valley tributaries, the total 1989 salmon stock was 32% lower than in 1988; however, late-fall salmon in the upper Sacramento River had a run size similar to that of 1988. The winter run in the mainstem Sacramento River was at a record low level. (PDF contains 44 pages.)

An analysis of methods of sampling to determine the size composition of commercial landings of yellowfin tuna, Neothunnus macropterus, and skipjack, Katsuwonus pelamis

ENGLISH: The staff of the Inter-American Tropical Tuna Commission is collecting and analyzing catch statistics of the Eastern Pacific fishery for yellowfin tuna (Neothunnus macropterus) and skipjack (Katsuwonus pelamis) in order to provide the factual information required for maintaining the catch of these species at maximum sustainable levels (Shimada and Schaefer, 1956). Careful, systematic and continued studies of the population structure, life history, and ecology of these species are needed for a proper and adequate interpretation of the catch statistics so that a sound conservation program may be achieved (Schaefer, 1956). SPANISH: El personal científico de la Comisión Interamericana del Atún Tropical cumple, entre sus tareas, la de reunir y analizar las estadísticas de pesca del atún aleta amarilla (Neothunnus macropterus) y del barrilete (Katsuwonus pelamis) de la pesquería del Pacífico Oriental, a fin de adquirir la información necesaria para mantener la pesca de estas especies a niveles de producción máxima sostenible (Shimada y Schaefer, 1956). Estudios cuidadosos, sistemáticos y continuos de la estructura de la población y ciclo de vida y ecología de estas especies, son necesarios para lograr una interpretación adecuada de las estadísticas de pesca, de modo que éstas, a su vez, permitan realizar un programa conservacionista serio (Schaefer, 1956).

Nährstoff-Einträge aus der deutschen Aquakultur in die Ostsee

Es gibt vier bzw. fünf große Gewässereinzugsgebiete mit Bedeutung für die Fischzucht. Dies sind die Donau mit ihrem Abfluß in das Schwarze Meer, Rhein, Weser und Elbe, die in die Nordsee entwässern sowie die Oder, die in die Ostsee mündet. Daneben gibt es noch einige weitere kleinere Flüsse von Nordwesten bis Nordosten Deutschlands, die in Nordsee (z. B. Eider, Stör) oder Ostsee (z. B. Stebnitz) fließen und das Ablaufwasser von Fischzuchten transportieren können.

Nutrient-phytoplankton interrelationships in the Eastern Tropical Pacific Ocean

ENGLISH: Near surface nutrient distributions in the eastern tropical Pacific Ocean, using data from the EASTROPAC Expedition of 1967-68 and pre~EASTROPAC data, are described. Nutrient concentrations were maximal along the equator, in the Peru Current and its offshore extension, and in the Costa Rica Dome and westward tensions of this feature. Nutrient-poor water was found north of the equator well offshore. In this water nitrate was often undetectable (<0.1 µg-at/liter) at the surface, but phosphate and silicic acid concentrations were moderate. Enrichment experiments showed that nitrogen was the primary limiting nutrient in poor water even though large amounts of organic N were found. Half saturation constants (K s ) were determined for ammonium-supported phytoplankton growth. These data were used to calculate near-surface primary productivity values which compared favorably with 14C values. Assimilation ratio measurements indicated that algae were not extremely nitrogen-deficient. Laboratory-determined K, values for phosphate and silicic acid indicated that these nutrients were rarely limiting. In rich water, chlorophyll levels were less than expected from nutrient levels, and this anomaly may be related to limitation by nutrients other than nitrogen (N), phosphorus (P), or silicon (Si), or to grazing. SPANISH: Se describe la distribución subsuperficial de los nutrientes en el Océano Pacífico oriental tropical, empleando los datos de la Expedición EASTROPAC de 1967~68 y datos anteriores a éstos. La concentración de nutrientes fue máxima a lo largo del ecuador, en la Corriente del Perú, en su prolongación mar afuera, en el Domo de Costa Rica y en las prolongaciones occidentales de esta característica. Se encontraron aguas pobres en nutrientes al norte del ecuador y bastante mar adentro. En estas aguas el nitrato era casi imperceptible (<0.1 µg-at/litro) en la superficie, pero las concentraciones de fosfato y ácido silícico fueron moderadas. Los experimentos de enriquecimiento indicaron que el nitrógeno era el principal nutriente limitante en aguas pobres, aun cuando se encontraron grandes cantidades de nitrógeno orgánico. Se determinaron las constantes de saturación media (K s ) para el desarrollo del fitoplancton sostenido por el amonio. Estos datos se emplearon para calcular los valores de la productividad primaria cerca a la superficie que pueden compararse favorablemente con los valores del 14C. Las medidas de la proporción de asimilación indican que las algas no tenían una deficiencia extremada de nitrógeno. Los valores determinados en el laboratorio de K, para el fosfato y ácido silícico indicaron que estos nutrientes limitaron rara vez la producción. En aguas ricas, los niveles de clorofila fueron inferiores a lo esperado según los niveles nutritivos y esta anomalía puede relacionarse a la alimentación o a la escasez de otros nutrientes distintos al nitrógeno (N), fósforo (P) o silicio (Si).

A review of bonga fisheries of the Cross River State, Nigeria

The Nigerian pelagic fishery contributes about two-thirds of the total marine fishery resources of the country. The main components of this fishery are the clupeid (Ethmalosa, and Sardinella spp) and the scombroid (jacks, barracuda and tuna) fisheries. In 1979 to 1983, fish production from the national inshore and brackishwater zones was 1,702,685 tonnes. Bonga (Ethmalosa fimbriata) which dominates the pelagic fishery in the Cross River State of Nigeria, contributed about 158,612 tonnes (i.e. 9.3%) of this national marine fish catch. Although bonga is caught along the entire Nigerian coast, a significant fishery exists mostly in the wider estuary of the Cross River State, which borders on the Cameroon Republic. In the Cross River State, and within the period, bonga contributed 24% to the marine fish landings. Bonga is supported by a single species (E. fimbriata). The species forms an important fishery all the year-round in the open sea off these estuaries, whenever the canoes venture to sea, but these open sea fisheries are affected by whether conditions. The best, and most suitable gear for bonga are the gill nets, cast nets, boat seines, and shore seines. Dried and smoked bonga are a common market commodity in the southern parts of the country generally, but particularly in the Cross State where it is a readily available and acceptable food item

A review of the Japanese longline fishery for tunas and billfishes in the Eastern Pacific Ocean, 1981-1987

ENGLISH: This report reviews the activity of the Japanese longline fishery in the eastern Pacific Ocean during the 1981-1987 period, extending the studies for the 1956-1980 period made by other investigators. The spatial and temporal distributions of fishing effort, catch, apparent abundance, sexual maturity, and size composition are examined for the principal species of tunas and billfishes taken by that fishery. The interaction between the surface and longline fisheries is discussed. SPANISH: En este informe se presenta un repaso de la actividad pesquera de barcos palangreros japoneses en el Océano Pacifico oriental durante el periodo de 1981-1987, extendiendo los estudios del periodo de 1956-1980 realizados por otros investigadores. Se examinan las distribuciones especial y temporal de les fuerzo de pesca, la captura, la abundancia aparente, la madurez sexual, y la composición por talla de las principales especies de atunes y picudos capturadas por dicha pesquería. Se comenta la nteracción entre las pesquerías de superficie y palangrera. (PDF contains 171 pages.)

Compensating restrictive fisheries management measures: distribution of improved cocks to Kainji Lake communities 1997-2001

The Nigeria-German Kainji Lake Fisheries Promotion Project (KLFPP) promoted the distribution of genetically improved cocks to the Kainji Lake (Nigeria) fishing communities aiming to compensate for possible short-term income losses due to the implementation of fisheries management measures restricting the use of the Lake's resources and to provide alternative sources for income generation, especially for the women. Out of 5,075 cocks produced, 4,171 cocks were distributed at subsidized prices mainly to women in 116 fishing villages of Kainji Lake. During an impact survey carried out in 12 villages, 6-24 months after distribution, only 25% of the cocks distributed were seen. However, potential income for each beneficiary from the hybrid offspring was estimated at minimum 1,000 Naira per year
