  <dc:description>&lt;div class=""&gt;&lt;div class="article-section__content en main"&gt;&lt;p&gt;Channel catfish&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Icialurus punctatus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;ranging from 70 to 148 mm in total length were treated with formalin at a concentration of 25 μL/L for 4 h daily on four successive days each week over a 28-week period beginning in mid-September. Coefficients of condition (weight-tolength ratios) and histological examinations of gill tissues were used to evaluate health of fish exposed to formalin. Gill tissues of both formalin-treated and untreated fish showed effects typical of intensive culture, including hypertrophy, hyperplasia, and excess mucous secretion; no differences were found in gill morphometry between the two groups. Channel catfish periodically treated with formalin had a significantly higher coefficient of condition (P &amp;lt; 0.05) after 28 weeks and no indication of adverse effects attributable to formalin.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
