Abstract :

<p>&nbsp;<span style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">The present study was conducted to evaluate the acute toxicity of catechol to <i>Clarias batrachus</i> along with its effects on haematological, biochemical and reproductive changes of fish. 96h median lethal concentration (LC₅₀) of catechol along with its 95% confidence limits was </span><span style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">30.74 (30.02-31.56) </span><span style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">mg/l.

A significant decrease (p&lt;0.05) in total serum protein along with maturity index (MI) and significant increase (p&lt;0.05) in total serum glucose was observed in treated fish for both the sublethal doses compared to control <span class="citationweb">in case of catechol</span>. </span><span lang="EN-GB" style="text-align: justify; background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">The findings of the study </span><span style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">may help forecast </span><span lang="EN-IN" style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">safe levels of catechol and portray </span><span style="text-align: justify; font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;">the health status of fish in natural water bodies.</span></p> <p class="MsoNormal" style="margin-left:-9.0pt;text-align:justify;text-justify:&#10;inter-ideograph;line-height:200%"><b><span style="font-size: 12pt; line-height: 200%; font-family: &quot;Times New Roman&quot;, serif;"><o:p></o:p></span></b></p>
