The ammonia meter is equally suitable for use in laboratories and treatment plants, and for direct field testing.
Variables measured were dissolved oxygen (mg/L), temperature ([degrees]C), conductivity (mS), pH (using a model 60 and 85 YSI meters; Yellow Springs Instruments), turbidity (NTU; using a LaMOTTE portable turbidity meter; LaMOTTE Instruments), ammonia (mg/L; using a Hanna portable ammonia meter; Hanna Instruments), maximum depth (cm), and volume ([m.sup.3]) in each pool prior to sampling fish.
