I'm trying to achieved a normalized number of brook trout stocked in lake by life stages. As stocking can be realized with eggs, fry, alevins or 1+ individuals, those "stocking intensity" in sens of number of individuals stocked are difficult to compare (as more eggs are normally stocked than 1+ fish). Applying a stages-specific % of survival to the sexual maturity, or reproduction can help normalize those numbers.
Yes - the best reference would be:
Peterson et al. 2008. When eradication is not an option: modeling strategies for electrofishing suppression of nonnative brook trout to foster persistence of sympatric native cutthroat trout in small streams. North American Journal of Fisheries Management 28:1847-1867
But the following would also be good to read to help provide context:
Peterson and Fausch 2003 Testing population-level mechanisms of invasion by a mobile vertebrate: a simple conceptual framework for salmonids in streams. Biological Invasions 5:239-259.
Peterson et al. 2004. Population ecology of an invasion: effects of brook trout on native cutthroat trout. Ecological Applications 14:754-772
These papers studied wild fish, but ratios should be analogous...
Thanks you M. Rogers, that's exactly the kind of data I and the student working with me needed.
