Effect Of N.P.K on the Larval Survival Of Oreochromis niloticus
ABSTRACT
Three
concentrations of aqueous solutions of N.P.K 15:15:15 were prepared
corresponding to recommended fertilization rates of 120kg/ha/2 weeks on a lha
pond of 0.8m depth for N.P.K. These were serially diluted to yield 0.0mg/1,
4.5mg/I and 15mg/I and 22.5mg/l respectively in control; treatment I, 2 and 3
were used for N.P.K fertilizer. O. niloticus larvae was exposed to the media
for 72 hours during which the larvae were swimming eractically, vigour lost,
decrease in feed intake with increase in concentration, the toxicity lead to
reduction in survival with increase in concentration. Water quality examination
should a decrease in dissolved oxygen content and increase in alkalinity and
total hardness. Toxicological implications of this finding in relations to
aquatic ecosystems and biodiversity are discussed.
