The Impact of Lake Ecosystems on Mineral Concentrations in Tissues of Nile Tilapia ( L.).

This study evaluates the differences in mineral and toxic trace element concentrations of Nile tilapia () tissues from three aquatic ecosystems in Ethiopia-Lake Ziway, Lake Langano, and Gilgel Gibe reservoir-with a focus on edible (fillet) and discarded (digestive tract, gills, skin, and liver) parts. A total of sixty ( = 60) Nile tilapia samples were collected, comprising twenty ( = 20) fish from each lake, and analyzed by inductively coupled plasma mass spectrometry. All elements varied markedly among tissues and between the lakes.
