Telescope Shiners, Length vs Mass



We have the first monthly set of length vs weight measurements for telescope shiners, from fish collected in Hurricane Creek February 3. This figure pools males and females, since it wasn't possible to sex them from external examination.


This r-squared value of 0.81 seems to be typical of local shiners in north 'bama. I suspect that as the season goes on we'll see a divergence between males and females, as females become proportionally heavier relative to length.

Neat! Sounds like the telescope shiner project will be really interesting! I may stop by next week and try to catch someone in the lab, I'd like to hear more about the results.
