However, for certain species such as Atlantic salmon, detecting the presence or abundance of a particular life history stage is more relevant than only knowing of their presence.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Life stages of organisms share the same eDNA, but messenger RNA (mRNA), which is found in cells, varies by the stage and physiological state of that organism. The research team has successfully sequenced Atlantic salmon and Atlantic cod mRNAs from aquaculture tank samples.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u201cThis proof of concept introduces eRNA as a potential frontier technology to monitor physiological events in captive and wild species,\u201d says Zegers.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Zegers and Grey have done some pilot work with water samples from the Green Lake National Fish Hatchery in Ellsworth and were able to get encouraging preliminary results. <\/span><span style=\"font-weight: 400\">Sherrie Sprangers<\/span><span style=\"font-weight: 400\">, co-chair and professor in the Environmental and Biological Sciences Division at UMaine Machias, and Zeger are currently working on the development of the DNA aptamers in hopes to devise a way to capture cells from water.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The team will be following the Downeast Salmon Federation fish out of East Machias until they are stocked in hopes to use the DNA aptamer as a tool to follow them in nature. Monitoring smoltification with eRNA could reduce the use of costly rotary screw traps (the current primary tool for monitoring smolts) and allow monitoring of parr-smolt dynamics to portions of watersheds that are currently inaccessible for screw traps.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The National Science Foundation award to Maine EPSCoR is #OIA-1849227.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Machias, Maine \u2014 The development of an environmental RNA (eRNA) marker to advance research in Atlantic salmon aquaculture and restoration efforts, led by University of Maine and University of Maine at Machias professors, has received a $20,000 seed grant supported by a National Science Foundation award to Maine EPSCoR at the University of Maine.
