Pond Boss Forums STOCKING A NEW POND Raising Forage and Bait Crawfish Crappie or Trout Forage; Yay or Nay?

I don't know how well the crawfish would do in a pond scenario when the main focus was Brook Trout due to water temps. Brookies are more sensitive to higher water temps and the resulting lower DO levels than other trout species.

"Dissolved Oxygen Levels:

EPA criteria for no impairment of salmonid production (USEPA 1987):

Embryo and larval stages 11 mg/l
Other life stages
8 mg/l

Normal activity: > 5 - 6 mg/l dissolved oxygen (Baker et al. 1993)
Spawning season: > 7.0 mg/l (necessary for egg survival)

Rainbow trout are more tolerant of low dissolved oxygen
levels while brook trout are particularly sensitive
to low dissolved oxygen levels (Camp Dresser and McKee 1981)."
