Abstract

Wet Season Variations of some Physicochemical Parameters of the Brackish Water farm, Buguma, Niger Delta, Nigeria

Owhonda KN

Some physicochemical parameters of Nigerian Institute for Oceanography and Marine Research/African Regional Aquaculture Centre (NIOMR/ARAC) brackish water fish farm; Buguma; Rivers State; Nigeria were monitored twice each month from April to October in 2011 and 2012; covering wet season for both years in the region. The result obtained indicates that for 2011 pH; ammonia-nitrogen; nitrite-nitrogen; nitrate-nitrogen; alkalinity; carbon (iv) oxide; salinity; dissolved oxygen and temperature ranges were between 6.5-7; 0-0.1 ppm; 0.25-0.25 ppm; 40-80 ppm; 5-10 ppm; 9-20 ppt; 3.8-6 ppm and 26-31oC respectively while for 2012 pH; ammonia-nitrogen; nitritenitrogen; nitrate-nitrogen; alkalinity; carbon (iv) oxide; salinity; dissolved oxygen and temperature ranges were between 6.5-7; 0-0.1 ppm; 0.05-0.05 ppm; 0.05-0.25 ppm; 40-80 ppm; 5-10 ppm; 9-20 ppm; 3.8-5.6 ppm; 26-31oC respectively. There were no significant differences (p>0.05) in all parameters for both years and the values measured were within tolerable limits for optimum aquaculture.
