Productividad primaria en un estanque de cría de peces (31°12’S; 57°55’W)

Gross and net primary productivity, respiration and related parameters were estimated in an experimental fish pond where silverside (Basilichthys bonariensis) were bred, using the oxygen light-dark bottle method. The results obtained showed a positive correlation (r = 0.83, p < 0.005) with te...

The results obtained showed a positive correlation (r = 0.83, p < 0.005) with temperature. The chlorophyll a concentration, the number of phytoplankton cells and the Secchi disk showed no correlation with primary productivity.The mean gross primary productivity on sunny days was 2022 g C m-2 day-1 in the deepest zone, with a 47% variation. For the whole pond the results was 358.7 KgC ha-1 year-1 considering a correction for statistical average of sunny days. The respiration/ gross primary productivity relation was 0.50 for the whole pond.With comparative purposes the primary productivity was estimated with the simplified method of daily curves and by the method of oxygen changes in open waters.
