Distribution of gill Monogenean parasites from Oreochromis niloticus (Linn, 1758) in man-made Lake Ayam I, Cte dIvoire

Parasites of native Cichlidae populations and invasive Oreochromis niloticus (Linnaeus, 1758) in tributary of Amazonas River (Brazil) Parasitos de populações de Cichlidae nativos e invasora Oreochromis niloticus (Linnaeus, 1758) em tributário do Rio Amazonas (Brasil)

This study provides the first investigation on acquisition of parasites in invasive O. niloticus by parasite species of native Cichlidae from the Igarapé Fortaleza basin, Northern Brazil. There were examined 576 specimens of 16 species of native cichlids and invasive O. niloticus collected in the main channel and the floodplain area of this tributary of Amazon River. The invasive O. niloticus w...

Cultured gill epithelial cells from tilapia (Oreochromis niloticus): a new in vitro assay for toxicants.

A culture gill epithelium from seawater-adapted tilapia (Oreochromis niloticus) was developed for testing PAHs and dioxin-like contaminants in seawater. The epithelia consists two to three layers of epithelial cells incorporating both pavement cells and mitochondria-rich cells (MRCs). Polarity and a stable transepithelial resistance (TER) were maintained, and closely resembled those in fish gil...

Gill monogeneans of Nile tilapia (Oreochromis niloticus) and red hybrid tilapia (Oreochromis spp.) from the wild and fish farms in Perak, Malaysia: infection dynamics and spatial distribution

Tilapia is one of the commercially important fish in Malaysia as well as in other parts of the world. An understanding of monogenean infection dynamics in tilapia fish may assist us in searching for some intervention measures in reducing the loss of fish caused by parasitic diseases. The present study aimed (1) to compare infection level of monogeneans between the wild and cultured Oreochromis ...

Charaterisation of Salmonella Isolated from Nile Tilapia (Oreochromis niloticus) along Lake Victoria Beaches in Western Kenya

Foodborne Salmonella infections have become a major problem world wide. Salmonellosis transmitted from fish are quite common. Established quality control measures exist for export oriented fish, none exists for fish consumed locally. This study aimed at characterization of Salmonella isolated from Nile tilapia . The study was carried out in selected beaches along L. Victoria in Western Kenya be...

Effects of triploidy induction on growth and masculinization of red tilapia [Oreochromis mossambicus (Peters, 1852)×Oreochromis niloticus (Linnaeus, 1758)]
