  <dc:description>&lt;p&gt;&lt;span&gt;Fisheries managers need effective methods to limit the spread of invasive round goby&amp;nbsp;&lt;/span&gt;&lt;i&gt;Neogobius melanostomus&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in North America. Elevating carbon dioxide (CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;) in water at pinch points of rivers (e.g., inside locks) is one approach showing potential to deter the passage of invasive fishes, such as bigheaded carps&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;i&gt;Hypophthalmichthys&lt;/i&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp., but the effectiveness of this method to alter round goby behavior has not been determined. The goal for this study was to determine CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;concentrations that alter round goby behavior across a range of water temperatures. Free-swimming avoidance (voluntary response) and loss of equilibrium (involuntary response) were quantified by exposing round goby to increasing CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;concentrations at 5, 15, and 25 °C using a shuttle box choice arena and static tank. Water chemistry was measured concurrent with behavioral endpoints and showed that round goby avoided a threshold of 99–169 mg/L CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;(79,000–178,000 µatm) and lost equilibrium at 197–280 mg/L CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(163,000–303,000 µatm). Approximately 50% lower CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;concentrations were found to modify behavior at 5 °C relative to 25 °C, suggesting greater effectiveness at lower water temperatures. We conclude that CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;modified round goby behavior and concentrations determined in this study are intended to guide field testing of CO&lt;/span&gt;&lt;sub&gt;&lt;span class="style1"&gt;2&lt;/span&gt;&lt;/sub&gt;&lt;span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;as an invasive fish deterrent.&lt;/span&gt;&lt;/p&gt;</dc:description>
