Catfish growth and survival were not related to average daily maximum NH(,3) exposures ranging from 63 to 183 (mu)g/liter, even though morning DO concentrations were often below 2 mg/liter.Subjects--Topical Terms:

520 $a Catfish growth and survival were not related to average daily maximum NH(,3) exposures ranging from 63 to 183 (mu)g/liter, even though morning DO concentrations were often below 2 mg/liter.
520 $a Rainbow trout and channel catfish were reared intensively in earthen ponds where water exchange did not affect water quality. Exposures of the fish to fluctuating dissolved oxygen (DO) and un-ionized ammonia (NH(,3)) levels in the ponds were related to fish growth, survival, and histopathology to investigate the effects of these parameters on limiting fish production.
520 $a In the trout ponds, DO was kept above 5 mg/liter with mechanical aeration, and average daily maximum NH(,3) concentrations ranged from 8.3 to 48.7 (mu)g/liter. Fish growth and survival were correlated with NH(,3) exposure, demonstrating the effect of this parameter on fish production.
520 $a Gill lesions characteristic of NH(,3) toxicity were noted in both species of fish. Livers of trout with the most gill damage demonstrated reduced glycogen vacuolation, indicating a dietary influence of NH(,3) that probably contributed to their reduction in growth. This effect was not noted in the catfish.
