Empirical Support for Linkage

?

  • In a study in which embryo-larval fathead minnows (Pimephales promelas) were exposed to the thyroid peroxidase inhibitor 2-mercaptobenzothiazole (MBT), T3 concentrations measured at 14dpf were reduced at the same concentration (1 mg/L) that significantly reduced anterior swim bladder inflation at the same time-point (Nelson et al. 2016).
  • Maternal injection of T3, resulting in increased T3 concentrations in the eggs of striped bass (Morone saxatilis) lead to significant increases in both swim bladder inflation and survival (Brown et al., 1988).

Uncertainties or Inconsistencies

?

  • Li et al. (2011) reported impairment of swim bladder inflation in Chinese rare minnows (Gobiocypris rarus)exposed to exogenous T3.
