NYACK - The Department of Environmental Conservation says that an increase in dead fish in the Hudson River is not related to the new Tappan Zee Bridge construction, but one local boater is fighting to better protect an endangered species.

Daniel Wolff says that he and his friends have seen five dead sturgeon in and along the shore of the Hudson River over the last few months.

According to the DEC permit, only four of these fish can be incidentally killed due to the construction, but DEC officials say no dead sturgeon has been linked to work on the bridge.

Wolff says that he would like to see some sort of permit that would hold the construction companies accountable for the fish.

DEC officials say they are keeping a close eye on all permitted activities by doing on-site inspections. They also have a DEC environmental compliance monitor who is on-site at all times.
