Effect of the diet on lipid composition and liver histology of short snout seahorse Hippocampus hippocampus

摘要: Little is known about the nutritional requirements of ornamental fish and effects which they may have on histology. Because this, 45 young, captive-bred seahorses (1.37 g ± 0.51) were randomly divided put into fifteen, 35-L, glass aquariums. Three experimental diets tested in triplicate: live enriched Artemia (LEA); frozen (FEA); commercial Mysis (M). fed twice daily, 6 days a week for 102 days throughout experiment. The body weight length measured every 20 days, at end experiment, liver samples taken histological studies. Biochemical analyses recorded, differences total lipid content each three also observed, reflecting their respective content. with LEA treatment showed vacuoles hepatocytes nuclei displaced to periphery. Similar results observed FEA seahorses, but lesser extent. In contrast, M characterized by having livers lower size centrally located nuclei.
