Imazapyr+imazapic herbicide determines acute toxicity in silver catfish Rhamdia quelen

Ecotoxicology and Environmental Safety, 2016
Imazapyr (IMY) and imazapic (IMI) are imidazolinone herbicides which have been associated in a commercial formulation (Kifix(®)). To date, there are no studies on the toxicity of an IMY+IMI herbicide in fish. This work aimed to assess the acute toxicity (24 and 96 h) of IMY+IMI (0, 0.488 and 4.88 µg/L) towards Rhamdia quelen through hematological ...

Waterborne ammonia and silver catfish, Rhamdia quelen: survival and growth Sobrevivência e crescimento de jundiá, Rhamdia quelen, exposto à amônia

Ciência Rural, 2011
The aim of the present study was to determine the effects of waterborne un-ionized ammonia (NH3) on the survival and growth of silver catfish (Rhamdia quelen). Juveniles were exposed to 0.10, 0.22, and 0.42mg L-1 NH3 at pH 8.2 for 45 days. After 15 days, a significant mortality rate (33%) was observed in the fish exposed to 0.42mg L-1 NH3.
