Hello All,
In Oregon I have found that in the summer months redside shiners also
expire
within minutes of capture. They are often dead in the seine. In the
winter
no problems. I speculate that being pulled from 50 degree water into 90+
degree air is enough of a shock to do them in.
When collecting for live specimens, I find winter to be most productive.
Pulling fish from 40 degree water into 40 degree air and them
transporting
them in a bucket seems to reduce mortality. I never collect live
specimens
in the summer.
Norm
