Variación de la composición bioquímica en hembras de merluza común (Merluccius hubbsi) durante el ciclo reproductivo
Provedor de dados: 20
Autores: Leonarduzzi, E.; Massa, A.E.; Manca, E.A.
The biochemical composition and energy content of muscle, liver and gonads of Merluccius hubbsi females during the reproductive cycle were assessed. Adult females (44-50 cm total length) were caught in the Patagonian area (43~' S-45~' S). Condition factor (K) and hepatosomatic index (HSI) were estimated. Proteins and lipids in each tissue were determined. Besides, water and ashes content in muscle was analyzed. In all tissues the biochemical components underwent variations during the reproductive cycle. During the process gonads showed a significant drop in protein and lipid content (P &lt; 0.01). In muscle, a decrease in proteins (P &lt; 0.01) and lipids in the postspawning period was observed; the percentage of both components increased during the...

Cambios bioquímicos post-mortem en músculos de diferentes especies pesqueras. Determinación de la vida útil de las mismas en frío
Provedor de dados: 20
Autores: Massa, A.E.
Se investigaron los cambios bioquímicos post-mortem y se determinó la vida útil comercial de tres especies pesqueras, muy valoradas por el sector industrial pesquero de nuestro país, durante el almacenamiento en frío: lenguado (Paralichthys patagonicus), corvina rubia (Micropogonias furnieri) y la vieira patagónica (Zygochlamis patagónica). Los cambios bioquímicos relacionados con el ATP y sus productos de degradación, la actividad de las principales enzimas involucradas en el catabolismo del ATP y el pH fueron investigados. En base a los contenidos de los compuestos relacionados con la degradación del ATP se establecieron distintos índices químicos para evaluar la frescura y/o la calidad de estos productos. Por otro lado, se monitorearon los niveles de...

Composición química y perfil de ácidos grasos de la anchoíta bonaerense en función del tamaño de los ejemplares y la zona de pesca
Provedor de dados: 20
Autores: Massa, A.E.; Fernández Compás, A.S.; Pennisi Farell, S.C.; Manca, E.A.
The aim of this study was to determine the chemical composition and fatty acids profile present in Argentine anchovy (Engraulis anchoita) northern population as a function of fish size and fishing area (SW Atlantic Ocean, Argentine Sea). Samples were collected during the northern stock assessment cruise of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) carried out on board of  FRV Capitán Oca Balda in Spring 2008 (OB-02/2008). The fishing trawls were performed between 34º 35' S and 40º 19' S. The area was divided in two zones: the northern, between 34º S-38º S, strongly influenced by the mixohaline waters of the Río de la Plata River estuary and the southern, between 38º S-41º S, that included the El Rincón coastal area. In each...
