| Analysis of the fatty acids of total lipids of wild fingerlings (1-4 g) of sea bass (<i>Dicentrarchus labrax</i>) caught off the northcoast of France shows that more than 30% of total fatty acids consists of the two essential fatty acids eiopentaenoic (C20:5 n-3) and docosahaenoic (C22:6 n-3) acids. One- and three-day old yolk sac larvae have even higher amounts of these two important fatty acids (about 40%). On the other hand, laboratory-reared 60-day old larvae had much lower concentrations of C20:5 n-3 (4% of total fatty acids) and C22:6 n-3 (5,5% of total fatty acids). In larvae suffering from whirling or spinning disease the percentage of C20:5 n-3 was only 2,8% and only traces of C22:6 n-3 were found. These results emphasize the... |

| Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37... |
