Representative images of the effects of perchlorate treatment on gonad development and reproductive stage in stickleback males and females. (A) Ovaries analyzed from adult control fish not treated with perchlorate (n = 4–6 individuals) contain ovarian follicles of all 4 stages of maturity. Follicles representative of each stage denoted with black arrows (B) Ovaries analyzed from adult fish treated with 100 ppm perchlorate (n = 4–6 individuals) contain predominantly stage 1 immature ovarian follicles, denoted with black arrows. (C) Testes from adult control fish not treated with perchlorate (n = 3–4 individuals) were found to be undergoing less spermiation and to be less mature than (D) testes from 100 ppm perchlorate treated fish (n = 3–4 individuals).
