This study was designed to mimic conditions that could exist during an accidental spill of hydrazine, a fuel for missiles and jet engines. Twelve‐day‐old eggs of rainbow trout Salmo gairdneri were exposed to nominal hydrazine concentrations of 0.01, 0.1, 1.0, and 5.0 mg/liter. The eggs were exposed for 48 hours and subsequently maintained in a recirculating‐flow system. Exposure to the various concentrations of hydrazine did not result in significant mortality or reduction in hatching. Aberrations in morphogenesis of larvae included loss of muscular control, reduced growth rates, and loss of tactile sensitivity at concentrations of 1.0 and 5.0 mg/liter.
