slingshotz Posted September 28, 2011 Report Share Posted September 28, 2011 The little fish are most likely chub minnows, or sucker fry. Both are in the majority of watersheds in Alberta and the golf course pond probably filled and top off the pond with some local stream/creek/river water. The big grass carp are also used in many ponds here to keep the vegetation in check but they are sterile so can't breed. They released a bunch into Lake Sundance to control the weeds, we managed to net one this year (during the perch netting harvest) and it was pretty cool to see.

Nauticus Posted September 28, 2011 Author Report Share Posted September 28, 2011 Normally I would agree that the many thousands, this is no exaggeration, of "minnows" could be native, except for the density per gallon which is not normal unless you are a salmon in the spawn of a west coast river. These were also not the typical shape of most native minnows. Having taught natural history in Edmonton this is something I am confident of. These were defiantly the fry of larger fish who had spawned in the pond without predators to cull the numbers down. Quote Link to comment Share on other sites More sharing options...
