Culture of sole, Solea senegalensis Kaup. Histomorphological and histopathological aspects

Abstract

Solea senegalensis is a common sole of Mediterranean waters, and it represents 95% of the sole catch in the southern part of Portugal. It is very similar to Solea vulgaris, a flatfish common in Atlantic waters. However, due to a decrease in the profitability of sea bream and seabass cultivation resulting from over – production in the Mediterranean area research efforts have been renewed. As a consequence, a big effort among Portuguese and Spanish research groups has been made during the last three years, in order to sole the principal problems of the cultivation of S. senegalensis, such as the nutritional problems related with the weaning, and pathology related to pigmentation of juveniles. The cultivation procedure as well as the pathological alterations during the production of juveniles will be presented.
