GROWTH AND SURVIVAL ON EXPOSURE TO LAMBDA CYHALOTHRIN AND AFLATOXINS OF DIETARY FISH FROM SELECTED AQUATIC SOURCES IN KENYA

Abstract

Toxicants cause a wide range of concerns in the health of fish. The specific objectives of the study were determine aberration of growth and survival as an iron indicator on exposure to lambda cyhalothrin and aflatoxins in dietary fish from selected aquatic sources in Kenya. The total wet weight was measured to the nearest 0.1g with an electronic weighing balance (Scanvaegt salter, model 323; Avery Weigh-Tronx Ltd, West Midlands, UK)Gen Stat Version 12, SPSS Version 21 and Excel 2010 were used in data analysis. The completely randomized design was adopted and Turkeys’ to separate the means having set the significance levels at p<0.05. The specific growth rate in length was lower in aflatoxin treated fish in bred fish. Garipenus Spp had the lowest the specific growth rate of 10.53 % on treatment with aflatoxin as compared to lambda cyhalothrin. In Oreochromis Spp the treatments affected the SGR equally giving a lower SGR of 24.6% compared to the control. The natural occurring toxins negatively affect growth and therefore relevant stakeholders be keen to prevent contamination from farm to fork.
