Seismic surveying off Newfoundland and Labrador could bring lasting effects to fish

Seismic surveying happening in Newfoundland and Labrador this year is leaving researchers and fish harvesters concerned over the health of fish and catch rates in the province’s waters. Seismic activity in the province is being carried out by Petroleum Geo-Services (PGS), with projects in Labrador, eastern Newfoundland and off of the Grand Banks. Weilgart said fish can also be harmed in other ways as a result of seismic surveying. She said  damage done by seismic surveying could lead to reflexes and immunity systems being compromised for long periods of time, which can make them more susceptible to predators. “Sometimes these [effects] are four months [after a survey], sometimes even a year, these impacts persist a year after the seismic survey ended,” she said. >click to read< 10:52
