Orange nodules in the skin of cultured turbot Scophthalmus maximus containing lipofuscin-like pigments
7 páginas, 10 figuras Orange nodules of different sizes (1 to 4 cm in diameter) were observed on the skin and fins of cultured turbot Scophthalmus maximus (L.). These nodules were located mainly in the dermis and hypodermis and were composed of numerous aggregates of pigment-laden macrophages surrou...
