We have the data for telescope shiner GSI through July now. Just as I suspected, June is the peak month for spawning as inferred from large GSI values (fraction of gonadal tissues as part of body weight). July fish are still elevated in GSI over May, but the end is in sight for the breeding season. Compared to other shiner data I've seen, the telescopes have a very focused one month peak. Usually it's a smoother rise and fall.
Here are the graphs, male and female:

"Usually it's a smoother rise and fall."
Do you have any other data from other species that you could share? I'd like to see the difference.
Good data. Do you think the drought could have affected the breeding season?
Cheers,
Andrew
