Estudou-se o tempo de conservação em gelo de 339 amostras de jaraqui escama fina (Semaprochilodus taeniurus)e 361 amostras de jaraqui escama qcossa (Semaprochilodus insignis).As amostras estudadas foram divididas em 17 lotes, dos quais se estudou as medidas morfométricas, peso e rendimento, bem como os testes sensoriais das características: EXTERNA, INTERNAS e ODORES DAS GUELRAS. A pontuação foi atribuida por uma equipe com um mínimo de 05 avaliadores. A chave proposta para avallar o frescor, ficou com 25 pontos para peixes recém-capturados e 08 pontos mínimos quando se tornava impróprio para consumo humano. Apresenta-se a composição centesimal dos lotes e as determinações de qualidade, tais como: pH, Rancidez oxidativa do músculo pelo método (TBA), Bases Voláteis Totals (BVT) e Trimetilamina (TMA). A duração média da conservação no gelo foi de 19,5 dias para o jaraqui escama fina e 17,5 dias para o jaraqui escama qrossa. | Storage life on ice (0°) was investigated for 339 samples of jaraqui Semaprochilodus taenlurue (Jaraqui escama fina) and 361 S. Inslgnis (jaraqui escama grossa). The sampie examined were divided Into 17 lote from which the following data was taken: morphometry measurements and weight and yield of diferent body sections. Subjetive evaluations were recorded for gill odor and for externai and internai appearance of freshness. The subjective scores were given by a team of at least five trained panelist. Twenty-five points were allocated for freshcaught fish and eight for non consumable fish. A nutritional composition analysis (humidity, protein, fat and ash) was performed on all lots. Quality determinates such as pH, free fatty acid (FFA), rancidity by means of the thiobarbituric acid (TBA) method, total volatile bases (TYB) and trimethylamine (TMA), were also carried out. The average ice storage life was 19.5 days for S. taenlurus and 17.5 days for 5. insignis.

Con este trabajo se informa la presencia de tres enfermedades virales que afectan a plantas de vicaria: mosaico del tomate (ToMV), mosaico del pepino (CMV) y mosaico del melón de agua (WMV-2). El ToMV y WMV-2 se aislan por primera vez de infecciones naturales en esta especie. El WMV-2 se detectó formando complejo con el ToMV y el CMV. | This paper is to report the presence of three virus diseases affecting plants of Catharanthus roseus L.: tomato mosaic (ToMV),cucumber mosaic (CMV) and watermelon mosaic (WMV-2). The ToMV and the WMV-2 were isolated for the first time from natural infections in this species. The WMV-2 was detected forming a complex with ToMV and CMV.

5 pages, 4 figures, 3 tables | [EN] Runoff that reaches an estuary was estimated as a function of daily rainfall in the drainage basin when the daily measurements of river flows are not available. This method is applied to the rivers flowing into the Ría de Vigo and compared with the River Deza that reaches the Ría de Arosa where the daily flow and rainfall are known. The optimum value of the retention coefficient (k = 0.75) is calculated. The distribution of flow calculated from the equation obtained and the surface salinity of the Ría de Vigo were related and a significant correlation (0.69) obtained. The values of estimated flows obtained by the proposed method are enough reliable to be used in studies of estuarine residual currents using the box model | [ES] Se hace el cálculo de los aportes de agua dulce que recibe un estuario en función de la precipitación diaria de la cuenca hidrográfica cuando no se dispone de medidas diarias de los caudales de los ríos que vierten en él. Se aplica este método a los ríos que vierten en la ría de Vigo comparándolos con el río Deza tributario a la ría de Arosa del que se conocen diariamente la precipitación y el caudal, y se calcula el valor óptimo del coeficiente de retención (k = 0.75). Se relacionan las distribuciones de los caudales estimados a partir de la ecuación obtenida y las salinidades superficiales de la ría de Vigo obteniéndose una apreciable correlación (0,69). Los valores de los caudales estimados aplicando el método propuesto, son lo suficientemente fiables para ser utilizados en estudios de corrientes residuales estuáricas empleando el modelo de cajas | This work was done within project MAR88-0245 supported by the CICYT and by the Consellería de Pesca de la Xunta de Galicia | Peer reviewed
