Geographical catch distribution of yellowfin and skipjack tuna in the Eastern Pacific Ocean, 1967-1970, and fleet and total catch statistics, 1962-1970

ENGLISH: Logbook records of tuna vessels fishing in the eastern Pacific Ocean were used to prepare charts showing the distribution of yellowfin tuna and skipjack catches by i-degree area, by quarter of the year, and by gear, for the years 1967-1970. Recent changes in the geographical distribution of yellowfin catch are illustrated. Also given are annual catch statistics and the composition of the international tuna fishing fleets which operated in the Commission's Yellowfin Regulatory Area each year, 1962-1970. SPANISH: Los registros de los cuadernos de bitácora de los barcos pesqueros de atún en el Océano Pacífico oriental se usaron para preparar gráficos que presentan para los años de 1967-1970, la distribución de captura del atún aleta amarilla y barrilete por área de 1 grado, trimestre del año y, por las artes. Se ilustran los recientes cambios en la distribución geográfica de la captura del atún aleta amarilla. Se presentan también las estadísticas de captura anual y la composición de la flota internacional de pesca, que explota cada año el Area Reglamentaria de la Comisión, 1962-1970.

A review of the Japanese longline fishery for tunas and billfishes in the Eastern Pacific Ocean, 1967-1970

ENGLISH: This report deals with the Japanese longline fishery for tunas and billfishes from 1967 through 1970, extending the studies made by Kume and Joseph (1969a, 1969b). The distribution of effort and catch is discussed and evaluated, and the changes in apparent abundance are examined. An analysis is made of the sexual maturity and size composition of the fish, and a brief comparison of the size composition of the catches from the longline and the surface fisheries is included. SPANISH: Este informe analiza la pesca palangrera japonesa de atunes y peces espada desde 1967 a 1970, ampliando los estudios hechos por Kume y Joseph (1969a, 1969b). Se discute y avalúa la distribución del esfuerzo y la captura, y los cambios en la abundancia aparente. Se hace un análisis de la madurez sexual y de la composición de talla de los peces y una breve comparación entre la composición de talla de los peces capturados en la pesca palangrera y la epípelágíca.

Fischbestände der Ostsee, ihre Entwicklung seit 1970 und Schlussfolgerungen für ihre fischereiliche Nutzung - Teil 2: Hering

The herring of the Baltic Sea shows a complicated population structure. Comparable to herring in other areas it can also be discriminated as spring and autumn spawning herring. Autumn spawning herring has been nearly vanished since the late 1960’s. Baltic Sea spring spawning herring show a broad variety as far as morphometric and other biological characteristics are concerned. It seems not very likely that all those differences are genetically based. The spawning sites of populations are, however, often clearly separated and such groups of herring are in most cases characterized by distinct differences in individual growth. Therefore for assessment purposes it is necessary to distinguish between as small as possible units in order to not endanger smaller populations to become extinct by overexploitation. On the other hand migrations and mixing of herring of different origin especially during the summer feeding period result in extreme difficulties of the discrimination of small units. For this reason only three herring assess ment units have been identified for the central and the northern Baltic Sea: herring in Sub-divisions 25–32+32, herring in Sub-division 30 and herring in Sub-division31. The spring spawning herring of the western Baltic Sea has been combined with spring spawning herring in Division IIIa. Only the herring stock in Sub-division 30 shows a positive development in the past. The largest assessment unit in Sub-divisions 25–29+32 decreased continuously during the whole period 1974–1998. The western Baltic Spring spawning herring stock decreased from 1990 to 1996. There is an ongoing debate on scientific level whether the combination of small populations into large assessment units like the one in S-D’s 25–29&32 might include the danger of the extinction of small compartments of the unit. On the other hand the practice by the International Baltic Sea Fishery Commission of managing the Baltic Sea herring fisheries by dividing a yearly Total Allowable Catch for the whole area among fishery zones without taking care of any biological structure and any individual stock development is totally against the idea of sustainability of fisheries.

Fischbestände der Ostsee, ihre Entwicklung seit 1970 und Schlussfolgerungen für ihre fischereiliche Nutzung - Teil 3: Sprotte

The sprat of the Baltic Sea is not as short-lived as inother Seas probably because fish predator species arerestricted mainly on cod and salmon. Sea bird popula-tions are much smaller and marine mammals are rare inthe Baltic Sea. The sprat stock biomass is fluctuatingstrongly. The fluctuation is mainly influenced by thestock recruitment and is also dependent on the strengthof the cod stock. After a strong decrease during the1980ies sprat catches increased again from 1992 onwardsand reached a peak with over half a million tonnes in 1997. At about the same time the character of the BalticSea sprat fishery changed from catches mainly for hu-man consumption to catches mainly for industrial pur-poses initiated by the fishery of Sweden. The recentrecord high catches of sprat have been possible only dueto the low level of the cod stock of the main Baltic SeaBasins over some years. A sprat fishery on such a highcatch level might cause conflicts with a recovering codstock in future.

Fischbestände der Ostsee, ihre Entwicklung in den Jahren seit 1970 und Schlussfolgerungen für ihre fischereiliche Nutzung. Teil 1: Dorsch

On the basis of the ”Gdansk Convention on Preservation of Living Resources of the Baltic Sea” the International Baltic Sea Fishery Commission (IBSFC) has been regulating catches of most important fish species in the area since 1974. This article reviews, in a first step for Baltic Sea cod, the development of stocks and fishery since 1970 in the light of respective catch regulations of IBSFC. TACs have been fixed by IBSFC by species for the whole Baltic Sea and resulting quotas have been split according to national and/or international fishery zones from 1975 up to now. The Baltic Sea cod is on biological background treated in scientific stock assessment as two separate stocks. Both stocks, in the western and eastern Baltic Sea, show clearly different developments over the period since 1970. After a short living peak in stock size of the eastern compartment about 20 years ago this stock has been on a very low level since the late 1980’s. During that period with increasing effort big cod catches have been landed.. The level of fishing effort is more or less the same still with much lower catches nowadays. A detailed description of development of stock sizes and recruitment is given. The conclusion is that with the present regime of regulation on the basis of one TAC for the total Baltic Sea and with high fishing capacity available for cod it will be impossible to meet the aim of good and stable yields.

Estimation of the relative annual abundance of yellowfin tuna, Thunnus albacares, in the Eastern Pacific Ocean during 1970-1985

ENGLISH: Estimates of relative annual abundance of yellowfin tuna in the eastern Pacific Ocean during 1970-1985 are made using catch rates, measured as tons caught by purse seiners per hour of searching. Catch rates are standardized a weighted generalized linear model. The important standardizing factors are vessel speed, season-area, and whether the yellowfin were caught in association with dolphins, skipjack tuna, or floating objects. Observations are weighted to give equal areas equal weight and to give each unit of fishing effort equal weight within an area. The results indicate that catch per days fishing underestimates abundance during the late 1970's when the fishery shifted some of its effort from dolphin sets to floating object sets, and overestimates abundance when the fishery shifted back to dolphin sets in 1984 and 1985. SPANISH: Se estima la abundancia anual relativa del atún aleta amarilla en el Océano Pacífico oriental (OPO) durante 1970-1985 por medio de tasas de captura, calculadas como toneladas cortas capturadas por barcos cerqueros por hora de búsqueda. Se usa un modelo lineal ponderado generalizado para estandardizar las tasas de captura. Los factores importantes de estandardización son la velocidad del barco, temporada-área, y si se capturaron los aletas amarillas en asociación con delfines, barriletes, o objetos flotantes. Se ponderaron las observaciones para otorgar igual importancia a áreas iguales y a cada unidad de esfuerzo pesquero dentro de un área. Los resultados señalan que la captura por día de pesca estima por bajo la abundancia durante los últimos años de la década de los 70, en cual época la pesquería trasladó parte de su esfuerzo de lances sobre delfines a lances sobre objetos flotantes, y la sobreestima al volver la pesquería a lances sobre delfines en 1984 y 1985.

Oceanographic and meteorological observations for project Little Window: March 1970

ENGLISH: Project Little Window was planned to provide some answers to the important scientific question of whether or not the HRIR (high resolution infrared radiometer) sensors aboard NASA and NOAA satellites can provide useful data for much of the oceanographic community. The sensors aboard these satellites were designed in response to the initial needs of meteorologists for temperature measurements integrated over a distance of 5-10 nautical miles and extending over a range from 30°C to about -75°C (i2-4°C). To this end the sensors have been a very powerful tool to the meteorologist in preparing daily weather advisories and in carrying out research. SPANISH: El proyecto Little Window fue planeado para suministrar algunas respuestas al importante tema científico sobre si los captadores (ltsensors") infrarrojos de alta resoluci6n (IRAR) a bordo de los satélites NASA y NOAA, pueden o no proveer datos útiles para la mayor1a de los oceanógrafos. Los captadores a bordo de estos satélites fueron concebidos en respuesta a las necesidades iniciales de los meteor6logos para obtener mediciones de temperatura integradas sobre una distancia de 5-10 millas náuticas, y entre 30°c y aproximadamente -75°C (~2-4°C). Con este fin los captadores han sido un instrumento poderoso para el meteor6logo en la preparaci6n de las informaciones diarias de tiempo y en la realizaci6n de las investigaciones.
