Germanium (Ge), in the form of germanic acid, at a Ge/Si molar ratio of 1.0 inhibits gemmule development and silica deposition in the marine demosponge Suberites domuncula. Lower Ge/Si ratios inhibit the growth in length of the silica spicules (tylos

Using light and electron microscopy, a study of the development of the lateral line system of the sea bass Dicentrarchus labrax, from embryo to adult, revealed that the first free neuromasts appeared on the head shortly before hatching and multiplied

This work is aimed at demonstrating the influence of insulin in the triggering of hepatic cholestasis in young gilt-head sea bream larvae reared under experimental conditions. The results are based on an immunological assay of insulin and an ultrastr

The olfactory organ of the European sea bass (Dicentrarchus labrax) in adults and during development has been studied by light microscopy and by transmission and scanning electron microscopy. This organ includes two cavities, each extended by an acce

The aim of this report is the synthetic presentation of observations related to ultrastructural aspects of the lipid metabolism during the ontogenesis of trophic mechanisms in three teleost species, the sea bass, Dicentrarchus labrax, the sea bream,

Under natural conditions, sea bass eggs hatch in the open sea and young-of-the-year sea bass are found close to estuaries and enter brackish and even freshwater lagoons in the Mediterranean and the eastern Atlantic. The ontogeny of osmoregulation in

The effects of glycerol added to seawater at different concentrations were tested in monocultures of Chlorella minutissima and Brachionus plicatilis in mixed cultures of these two species and on starved or fed Sparus aurata larvae. Glycerol enhanced

Insulin was sought during the early postembryonic development of gilt-head sea bream, Sparus aurata, using ultrastructural, immunohistochemical and biochemical techniques. The endocrine pancreas appeared at hatching (Day 0) as a single cluster of mor

The mechanism of biliary lipid secretion, which is poorly documented in high vertebrates and unknown in fish, was studied using cytochemistry and electron microscopy during early post-embryonic development in three teleostean species of aquacultural
