Abstract
Limnological parameters of the two freshwater fish ponds treated with artificial feed or buffalo dung were studied. There were no significant differences between water temperature, light penetration, pH, electrical conductivity, dissolved oxygen, total hardness, nitrates and planktonic biomass, whereas highly significant differences were found between total alkalinity and phosphates between artificial feed and buffalo dung treated ponds djudge the impact or dille rent extension educa,ion methodS used hy 'he Field Veterinary Staff for the dissemination of modern livestock farming practices among the farmers, Ten livestock farmers were taken randomly from each Veterinary Hospital ar ea and as such sample A eonsisled of 100 ,espondenls.
