So the "90% of the population is male" is an anecdotal observation of the adults you've obtained? Likely being wild caught, this wouldn't be too surprising.

I think a 90% male claim on a wild population or birth rate would be rather suprising. A near even split was observed in birth rates in The Sex of Triploids and Gynogenetic Diploids in Bombina orientalis (a 1980 paper, full pdf is available at the link, near 50/50 split of sexes in their control group).
