Mount Royal potato farmer Warren Ellis and his company Warren Ellis Produce Inc. made a brief court appearance on Tuesday.
Both Ellis and his company are facing one count each under the Federal Fisheries Act of allowing a deleterious substance into water frequented by fish.
The charges stem from between July 3 and 7 of 2012.
During that timeframe about 100 dead fish, mostly trout, were found floating in the Barclay Brook section of the Trout River.
Ellis and his produce company are currently awaiting sentencing in two separate cases, to which they pleaded guilty in December.
One case stems from a 2011 fish kill and involves one charge of allowing a deleterious substance into a waterway containing fish (also on the Trout River).
The second case involves a charge under the provincial Crop Rotation Act. That case is set for sentencing on Feb. 13.
