| In the liver of rainbow trout (Salmo gairdnerii ), vitellogenin (Vg) synthesis is influenced by oestradiol (E sub(2)) which is believed to act through the classical mechanism of steroid hormone action. After binding of the hormone to a soluble specific receptor protein, the oestradiol-receptor complex is translocated to the nucleus, where it interacts with DNA and modulates expression of Vg genes, leading to increased synthesis of specific mRNA and Vg. The authors show here: (i) the presence of specific oestrogen receptors in the cytosol of the male trout liver. (ii) The male liver, offering, an ideal experimental control of "zero" background, the authors followed - in the liver of male trouts - the kinetics of induction of Vg mRNA by hybridization with Vg... |

| The by-products (viscera, heads, backbone and skins) of tongue sole coming from a Senegal frozen fisherie plant, were hydrolized with the Protamex® enzyme.Degrees of hydrolysis of 30 and 19% were obtained respectively with 40°C and 50°C.The results also showed that the proteins contained in these by-products are completely solubilized by the action of this protease at the end of 180 minutes of hydrolysis. The biochemical characterization showed that these hydrolysates are rich in proteins (61%) and minerals (10%). However, the hydrolysates contain peptides of lower molecular sizes 1760Da.Lastly, these hydrolysates have high nutritional value in order to set up table fowls because they have in big quantity 9 essential amino acids for the poultry feed. |

| Confusion has arisen over the nomenclature of certain fish of the family Centracanthidia, because of the colour variations due to sexual dichromatism, sexual inversions, protogynous hermaphroditism, and seasonal modifications according to the stage of maturity. A historical survey of nomenclature is presented for species described under the genera Maena, Smaris and Spicara, the last being the most recent. A morphological study and an electrophoretic study of the crystalline lens of the various species involved is described. The techniques and standards used are given. As a result of the study, and bearing in mind the effects of the variations mentioned above, it was concluded from electrophoretic comparisons that only 2 species are valid, Spicara maena and... |

| Thau is a mediterranean lagoon with a large productive stock of molluscs (oysters, mussels) cultivated on suspended tines and colonised by epibionta (ascidia and others invertebrates, algae, etc ... ). This study was developed as part of the PNOC-OXYTHAU.programme. Its aim was to analyze the effects of oyster farrning on water-mass surrounding structures loaded with suspended molluscs and proximal watermass separating these structures. This study concems particulate suspended matter and deposits of particulate organic matter on the bottom after sedimnentation. Biochemical measurements were carried out for nitrogen, carbon, proteins, lipids and carbohydrates. ln order to estimate sedimentaton, bottom sediment traps were used |

| Toxic impact of sublethal concentration (1 mg/L; 5% of 96h LC50 value) of sodium arsenite (NaAsO2) on certain biomolecules (proteins, nucleic acids, lipids, and glycogen) of five tissue components (muscles, liver, brain, skin, and gills) of the freshwater catfish Clarias batrachus was analysed. The important toxic manifestations include marked decrease in the concentration of proteins (21.72-45.42% in muscles; 3.42-53.94% in liver; 15.39-45.42% in brain; 15.40-4.00% in skin and 11.35-64.13% in gills), DNA (0.55-22.95% in muscles; 8.33-14.06% in liver; 5.30-18.40% in brain; 13.57-52.80% in skin; and 12.38-31.01% in gills), RNA (42.68-76.16% in muscles; 10.68-39.75% in liver; 5.66-29.05% in brain; 7.72-27.93% in skin and 21.47-44.38% in gills) and glycogen... |
