Formalin sensitivity in rainbow trout

Formalin sensitivity in rainbow trout

Formalin is a commonly used prophalyctic antifungal and antiparasitic treatment of fish and fish eggs, yet little is known about the differential sensitivity among strains after exposure as eggs. This study seeks to determine the sensitivities (measured by mortality) of four rainbow trout strains, after first exposure to formalin as eggs, and a later exposure as fingerlings. The data is analyzed using logistic regression and a Cox proportional hazard model. Both models yield consistent conclusions; the different strains do die at different rates as fingerlings, but the egg treatment does not contribute to these differences.
