Hello fish folks,

I'm in a time crunch with a list of "have to do" things that hasn't gotten
any shorter in weeks, or I'd be able to look this up for myself.  Does
anyone have a good feel for the duration of time that species in the
following groups "typically" (if there is such a thing) spend as
larvae--that is, post hatch until they would be big enough to gain some
mobility and be better able to resist flow disturbances (either natural
spates or regulated flows?). Specific region is mid Atlantic highlands
(e.g., northwest PA).  Major groupings are small percids, catostomids,
cyprinids, and centrarchids.  I would imagine there is some variability
with temp. and other environmental factors. Any specific info or references
welcome but I'm really just trying to judge the size of the ball park.

Thanks in advance

Doug
