Remediation of Cayuga Syndrome in Landlocked Atlantic Salmon Salmo salar Using Egg and Sac‐Fry Bath Treatments of Thiamine‐Hydrochloride
Abstract A lethal thiamine deficiency, termed Cayuga Syndrome (CS), affects larval landlocked Atlantic salmon Salmo salar in several of New York's Finger Lakes. This syndrome has been linked to a maternal diet of alewife Alosa pseudoharengus that have high thiaminase concentrations within them...

Thiamine concentrations of at least 1,000 mg/L. during water hardening, or 10,000 mg/L if treated as moribund sac‐ky, were necessary to almost eliminate syndrome‐related mortality. When post‐treatment total thiamine tissue concentrations (i.e., the sum of thiamine pyrophosphate, thiamine mono‐phosphate and free thiamine) approached or exceeded a threshold of 0.8 nmol/g sac‐fry in the sac‐fry, mortality due to CS was significantly reduced.
