Abstract:
Study on nutrients content (nitrite, nitrite and ammonia) and distribution in cage
culture area of Setiu Lagoon, Terengganu was carried out with two sampling; the first
sampling on 19 - 20 December 2006 and the second sampling on 17 - 18 January
2007. The sampling involved only one station but carried out in one day cycle.
Nutrients that were measured in water samples were nitrate, nitrite and ammonia. The
objectives of this study are to determine the factor that gave effects to the nutrient
distribution and content and to determine the effect of North East Monsoon season to
the nutrient distribution. Based on the results of water samples analysis, the average
value and the range of nitrate concentration during the first sampling are 0.811 mg/L
(0.155 - 1.572 mg/L) for surface water and 0.936 mg/L (0.346 - 1.609 mg/L) for
bottom water. The average value and the range of nitrate concentration during the
second sampling are 1.740 mg/L (0.293 - 3.473 mg/L) for surface water and 0.771
mg/L (0.486 - 1.361 mg/L) for bottom water. The average value and the range of
nitrite concentration during the first sampling are 0.014 mg/L (0.009 - 0.020 mg/L)
for surface water and 0.020 mg/L (0.004 - 0.042 mg/L) for bottom water.
