1. Continue the current marking study investigating the effectiveness of stocking wiper
fingerlings vs. fry in terms of survival and cost. Use this information to refine the current
wiper stocking quota for fingerlings and fry."
I wonder if they have come up with a number, for the survival rate of the wiper fry they stock at Willard? I know they have said it could be as low as 1% or up to 10% but in 25 years, I don't remember them giving us an idea of what the survival rate actually is. Lots of other good info though.[/quote]
[#0000FF]From some other reports I got from DWR a couple of years ago...survival rate of the sac fry varies between .5% and 11%...with a lot of variables each year. Very difficult to monitor or verify because of the sheer numbers and small sizes of the fry.
On the other hand, the larger fingerling sized wipers show what appears to be close to a 50% survival rate. But they are more costly to produce.
