Tissue residues of formaldehyde were determined for striped bass Morone saxatilis of three size‐groups (total length, mean ± SD): 13.0 ± 0.9 cm, 15.5 ± 2.8 cm, and 33.9 ± 1.9 cm. The experiments conducted were a 144‐h exposure to a static solution of 25 mg formalin/L (9.3 mg formaldehyde/L) and a 1‐h exposure to a static solution of 250 mg formalin/L (92.5 mg formaldehyde/L). There were no statistical differences between formaldehyde residues in untreated (control) fish and fish exposed to 25 mg formalin/L for 24 h, but exposed fish did have significantly higher formaldehyde residues after 48 and 72 h of this treatment. Formaldehyde levels were back to normal after 96 h. Muscle formaldehyde residues were not significantly different between treated and control fish after treatment with 250 mg formalin/L. Additional formaldehyde was produced in tissues of control fish during decomposition during storage.
