Application of RAPD markers in fish: Part I – some genera (Tilapia, Sarotherodon and Oreochromis) and species (Oreochromis aureus and Oreochromis niloticus) of Tilapia
Random amplified polymorphic DNA (RAPD) analysis was applied to the four-tilapia species (three genera): redbelly tilapia (Tilapia zillii), white tilapia (Sarotherodon galilaeus), blue tilapia (Oreochromis aureus) and Nile tilapia (Oreochromis niloticus). Twenty random primers – fifteen (10-mer) and five (20-mer) – were used to assay polymorphisms among three genera and between two species. ...

Biomarkers and pollutants in the Nile Tilapia, Oreochromis niloticus, in four lakes from San Miguel, Chiapas, Mexico
The effects of the oil industry and environmental pollutants present in four lakes from Reforma, Chiapas, Mexico, were assessed via ethoxyresorufin O-deethylase activity (EROD), PAH metabolites, and butyrylcholinesterase activity (BChE) in Nile Tilapia, Oreochromis niloticus. Fish were collected during two seasons (the rainy season in September 2000 and the dry season in May 2002) from the lakes ...

Protective role of dietary N‐acetylcysteine on the oxidative stress induced by cylindrospermopsin in tilapia (Oreochromis niloticus)
Cylindrospermopsin (CYN) is a toxin produced by various cyanobacteria species. Fish can be exposed to this cyanotoxin in their natural environments and in aquaculture ponds, and toxic effects can be derived. The present study investigated the effects of dietary N‐acetylcysteine (NAC) on the oxidative stress induced by pure CYN and CYN from lyophilized cells of Aphanizomenon ovalisporum in tilapia ...

Time-Course Variations of DNA Damage and Biomarkers of Oxidative Stress in Tilapia (Oreochromis niloticus) Exposed to Effluents From a Swine Industry
Abstract DNA damage (Comet assay), lipoperoxidation levels (TBARS), and several biomarkers of oxidative stress such as catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx), glutathione S-transferase (GST), and contents of reduced (GSH) and total (TG) glutathione were measured in liver and blood (Comet assay) of tilapia (Oreochromis niloticus) exposed for 7, 15, 30 (subchronic ...

Mode of Action and Growth Toxicity of Arsenic to Tilapia Oreochromis mossambicus Can Be Determined Bioenergetically
Abstract We present a bioenergetics-based approach to analyze the chronic effects and growth toxicity mode of action in tilapia Oreochromis mossambicus exposed to waterborne As and to predict fish growth under different exposure scenarios. 7-day exposure bioassays showed that tilapia accumulate As when exposed to waterborne As. We conducted growth bioassays to assess chronic As toxicity to ...

A functional hydrolysate adds value to feeds for omnivorous fish species
Omnivorous fish species are known to be less demanding in terms of nutritional and palatability requirements and yet dietary hydrolysate supplementation greatly improved production yields and margins. Several biological benefits are associated with protein hydrolysates and they have been used in finfish larval and juvenile diets for several decades now, mainly due to their high palatability and ...
