Surface water contains a large number of pollutants, particularly human pathogens, organic toxicants and heavy metals. Due to the toxic nature of heavy metals towards marine organisms, its removal from the environment has been a growing issue. The biosorption of heavy metal ions from surface water using fish scales has emerged as an environmentally friendly technique. This study assessed the de...

Background: Aquatic pollution by pesticidal application, in recent times, has gained much attention throughout the world, as they ultimately reach to the aquatic bodies through agricultural runoff or by aerial spraying and finally, impair the health status of fish. The aim of the present study was to evaluate the toxicological responses of Almix® herbicide on oxidative stress parameters in thre...

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 ...

Lake Paranoá is a tropical reservoir for the City of Brasilia, which became eutrophic due to inadequate sewage treatment associated with intensive population growth. At present, two wastewater treatment plants are capable of processing up to 95% of the domestic sewage, thereby successfully reducing eutrophization. We evaluated both genotoxic and cytotoxic parameters in several fish species (Geo...

BACKGROUND Streptococcosis is an important disease of tilapia throughout the world. In Malaysia, streptococcosis outbreak was commonly reported during the 3-month period of high water temperature between April and July. This study describes the duration of protection following single and double booster dose regimes against streptococcosis in tilapia using a feed-based vaccine containing formali...

The present study was undertaken to investigate whether treatment with vitamin E (VE) protects against intoxication induced by lead (Pb) exposure in Oreochromis niloticus. Fish were exposed for 60 days to a 10 mg Pb / Kg diet. The oxidative stress affected by Pb in fish was treated by antioxidant (VE) supplementation. Fish were assigned to four dietary groups. The diets differed in their consti...

The contamination of heavy metals in water is a worldwide issue which increasing day by due to the different types anthropogenic activities. These pose serious health risk on aquatic organisms. One such metal chromium. present study about determine 24h, 48h, 72h and 96 hours LC50 value hexavalent chromium for Nile Tilapia, Oreochromis niloticus. In study, 96h exposure Tilapia (Oreoch...
