Upper Piscataquis to 30 times in the upper Penobscot. Furthermore, the required parr density is well within the observed range of densities for some reaches, and therefore may be obtainable. Clearly, variation in freshwater productivity can play an important role in assessing a reach’s potential to sustain a sub-population. However, this identifies a critical data gap. We need a spatially explicit random sampling scheme for juvenile salmon populations in the Penobscot basin to ascertain relative differences in productivity among the major management subdrainages. Furthermore, sampling needs to be sufficient to capture the variability of juvenile abundances within and among reaches. Table 4.

Mortality of both adults and smolts increased with the number of dams PRFP Page 138
that must be passed. Furthermore, he expressed population segment viability in half-lives, and showed that population viability was affected by the number of dams, with the Upper Piscataquis (Guilford) having the shortest half-life of 6.52 years and the segments with no dams or few dams (Mouth to Great Works) was self-sustaining (presented as 100 years). The population half-life estimates take into account population segment size and smolt production potential. Some parameters such as angling mortality have changed since 1986, and we now have updated dam survival data for some dams. Nevertheless, the findings from 1986 are consistent with our results.
