Are sardine larvae caught off northern Portugal in winter starving? An approach...
Chícharo, Alexandra; Esteves, E.; Santos, A. M. P.; Santos, Antonina dos; Peliz, A.; Re, P.Recently, winter upwelling events off western Iberia have become more frequent. This may affect the production and survival of sardine eggs and larvae through increased offshore transport. By analysis of RNA:DNA ratios, we investigated the impact of winter upwelling events on the larval condition of Sardina pilchardus larvae as a function of oceanographic conditions and food availability. Larvae were collected ...

Estimation of starvation and diet variation of the RNA/DNA ratios in field-caug...
Chícharo, Alexandra; Chícharo, Luís; Valdes, L.; Lopez-Jamar, E.; Re, P.The aim of this study was to analyse the general larval condition, to determine the lncidence of starvation and to investigate the effect of time of day on RNA/DNA ratios among field-caught Sardina pilchardus (L.) larvae. The larvae were collected during 4 research cruises off northern Spain, during March, April, May and June 1992. A highly sensitive fluorometric method for nucleic acid quantification was appli...
