Alvarez Del Castillo, Kelsey Sethi, Suresh A Won, Eugene Maniscalco, John Pendleton, Richard Ryan, Eliza Rudstam, Lars G Animals Introduced Species Salt Tolerance Salinity Temperature Perciformes Estuaries Ecosystem North America Rivers Seasons Since being introduced into the Laurentian Great Lakes in the 1990s, round goby (Neogobius melanostomus) has spread rapidly, reaching the Hudson River Estuary, NY in 2021. To address the expansion potential into saline environments from this North American coastal invasion front, we experimentally assessed the salinity tolerance of adult round gobies. Water temperatures vary widely in temperate aquatic ecosystems, and our study is the first to investigate the effect of temperature on the salinity tolerance of round goby, conducting tolerance trials at three temperatures: a preferred temperature of 20°C, 26°C reflective of summer conditions, and 5°C reflective of winter conditions. Adult round gobies were subjected to weekly salinity increases of 3 parts per thousand (ppt), concluding at 33ppt. Study specimens were monitored for stress cues (behavior changes and color changes), and mortality. We found significant salinity tolerance differences dependent on water temperature, with the highest tolerance at 5°C and the lowest tolerance at 26°C. By 30ppt, survival was 87% at 5°C and only 7% at 26°C. Based on mortality results, round goby expansion may occur year-round into brackish portions ( |
