Growth performance, body composition, and digestive functionality of Senegalese sole (Solea senegalensis Kaup, 1858) juveniles fed diets including microalgae freeze-dried biomass.

Senegalese sole is one of the most promising fish species cultivated in the Southern European countries. This study was aimed at assessing the effects of microalgae biomass added to diets for Senegalese sole juveniles on fish growing and condition status. Three isoproteic (52%) and isolipidic (10%) were formulated containing 15% Tisochrysis lutea (TISO), Nannochloropsis gaditana (NAN), or Scenedesmus almeriensis (SCE) biomass, respectively.

Physiological short-term response to sudden salinity change in the Senegalese sole (Solea senegalensis).

The physiological responses of Senegalese sole to a sudden salinity change were investigated. The fish were first acclimated to an initial salinity of 37.5 ppt for 4 h.

The centromeric satellite of the wedge sole (Dicologoglossa cuneata, Pleuronectiformes) is composed mainly of a sequence motif conserved in other vertebrate centromeric DNAs.

Here, a new satellite-DNA family is isolated and characterized from wedge sole, Dicologoglossa cuneata Moreau, 1881 (Pleuronectiformes), a fish having a small genome. This satellite-DNA family of sequences was isolated by conventional cloning after digestion of genomic DNA with the DraI restriction enzyme. Repeat units are 171 bp in length with a high AT content (63%).

Molecular characterization, phylogeny, and expression of c-type and g-type lysozymes in brill (Scophthalmus rhombus).

Lysozymes are key proteins of the innate immune system against bacterial infections. In this study we report the molecular cloning and characterization of the c-type and g-type lysozymes in brill (Scophthalmus rhombus). Catalytic and other conserved residues required for functionality were identified.
