Histological and histochemical observations in the stomach of the Senegal sole, Solea senegalensis.

Histochemical aspects of the yolk-sac and digestive tract of larvae of the Senegal sole, Solea senegalensis (Kaup, 1858).

Histochemical distribution of glycoproteins, carbohydrates and proteins rich in different amino acids were studied using histological and histochemical procedures, in Senegal sole, Solea senegalensis (Kaup, 1858) larvae from hatching until day 15. Glycogen, proteins and glycoproteins were detected in the yolk-sac of the larvae at hatching and during the yolk-resorption. The epithelial digestive...

Development of the Senegal sole, Solea senegalensis forebrain.

The present paper deals with the ontogeny of the forebrain of the flatfish Senegal sole, Solea senegalensis, through different developmental stages before and after to metamorphosis. A first approach was made by conventional histological techniques, which allowed the determination of the main ontogenetic events. A second approach was to analyze the proliferation zones (PZ) during development an...

Effect of daily thermo - and photo - cycles of different light spectrum on 1 the development of Senegal sole ( Solea senegalensis ) larvae

Male reproductive system in Senegalese sole Solea senegalensis (Kaup): anatomy, histology and histochemistry.

Despite the fact that the Senegalese sole Solea senegalensis is a target species for the aquaculture industry in Spain and Portugal, very little is known about its gametogenesis and especially about testicular development. Therefore, the male reproductive system in adult S. senegalensis was described using a histological and histochemical approach. Mean gonadosomatic index was very low (0.094+/...

Glyconjugates in epidermal, branchial and digestive mucous cells and gastric glands of gilthead sea bream, Sparus aurata, Senegal sole, Solea senegalensis and Siberian sturgeon, Acipenser baeri development.

Epidermal, branchial and digestive mucous cells, and the gastric glands of larvae/postlarvae (from hatching until 45 days posthatching) of three fish species (two teleostean and a chondrostean) were investigated using conventional histochemical methods (periodic acid schiff -PAS-, diastase-PAS; alcian blue pH 0.5, 1 and 2.5) in order to distinguish neutral and acidic (carboxylated and sulphated...
