Changes in benthic macrofauna in oyster parks during an OsHV-1 μVar oyster spat mortality outbreak

In intertidal areas, oyster farming creates a crosshatching pattern between tables and aisles. Tables provide refuge from the current solar irradiance oysters facilitate accumulation of OM, thereby structuring spatial organization associated macrozoobenthic community at mesoscale. The aim this study was to describe quality table environment small scale response OsHV-1 μvar mortality. species assemblage dominated by Golfingia vulgaris, Tubificoides benedii, Capitella capitata Scoloplos armiger. habitat appeared be in bad ecological state throughout 2-month survey (May June 2017), whereas aisle, eutrophication occurred lately clearly related due massive stranding dead seaweed end (in early July). So, disturbance seemed occur two phases: 1) after spat mortality 2) resulted status, as revealed macrofaunal indicators. Large quantities DNA were also found some species, including crabs amphipods, one week crisis, but there is no apparent virus reservoir benthic species.
