Transepithelial calcium uptake and transcellular calcium uptake mechanisms were compared in the proximal intestine of freshwaterand seawater-adapted tilapia, Oreochromis mossambicus. Stripped intestinal epithelium of seawater fish showed a higher paracellular permeability to calcium in vitro. Net transepithelial calcium uptake was 71% lower, reflecting a physiological response to the increased ...

Fish is a very important component of human diet. A total 64 samples Clarias gariepinus were collected from two fish ponds each in Yaba, Ijegun, Ikorodu and Epe Lagos State, Nigeria. The bacterial flora the fishes determined quantitatively qualitatively. mean viable count ranged log10 7.6 cfu/g to 7.9 cfu/g. load on skin intestine generally higher than gills. Salmonella between 7.2 it was highe...

Vibrio cholerae, the etiologic agent of cholera, is autochthonous to various aquatic environments, but despite intensive efforts its ecology remains an enigma. Recently, it was suggested that copepods and chironomids, both considered as natural reservoirs of V. cholerae, are dispersed by migratory waterbirds, thus possibly distributing the bacteria between water bodies within and between contin...

For sustainable aquaculture, the removal of marine resource ingredients in fish diets is an important objective. While most studies focus on the replacement of fish oil by vegetable oil, little is known on the nutritional effects of presence (which corresponds to the control diet) or absence of dietary fish oil. We studied fatty acid composition of brush-border membranes and digestive enzyme ac...

The fish intestinal microbiota is affected by dietary shifts or diet-related seasonal fluctuations making it highly variable and dynamic. It assists with the digestion and absorption of food that is a common, yet dynamic process. However, fundamental dynamics of microbial ecology associated with food digestion in intestine and stomach are poorly understood in fish. We selected the southern catf...

The absorption of Cl(-) and water from ingested seawater in the marine fish intestine is accomplished partly through Cl(-)/HCO(3)(-) exchange. Recently, a H(+) pump (vacuolar-type H(+)-ATPase) was found to secrete acid into the intestinal lumen, and it may serve to titrate luminal HCO(3)(-) and facilitate further Cl(-)/HCO(3)(-) exchange, especially in the posterior intestine, where adverse con...

This study aimed to highlight the relationship between diet, animal performance and mucosal adherent gut microbiota (anterior intestine) in fish fed plant-based diets supplemented with an egg white hydrolysate (EWH) antioxidant anti-obesogenic activity obese rats. The feeding trial juveniles of gilthead sea bream ( Sparus aurata ) lasted 8 weeks. Fish were near visual satiety a meal (FM)/fish o...

Seawater ornamental fish is an Indonesian fauna whose are very diverse and easily infested with parasite. Therefore, the quarantine procedures was necessary to prevent spread of parasitic disease. The purpose this study examine identication parasites in marine before transported from Fish Quarantine, Quality Control Safety Fishery Products Denpasar, Bali. Parasite examination carried out by con...
