A body has been recovered from the Severn Estuary at St Pierre Pill near Chepstow.
A search and rescue operation had been launched after a man was reported missing from a yacht in the area.
Coastguards as well as one lifeboat and two land teams from the Severn Area Rescue Association were involved in trying to find the missing person.
The search has since been called off.
Hundreds of thousands of baby eels have been released today as part of a conservation project.
The elvers try to swim upstream where they will grow into adults as our Gloucestershire correspondent Ken Goodwin reports.
The Environment Agency is patrolling the River Severn to watch out for elver poachers.
They're using boats with special imaging equipment so they can see in the dark. Other officers patrol the banks.

Mr Mott is wearing a head camera for some of the shots so you can see what he can see.
If what he is doing looks dangerous now, imagine what it is like in the dark, and in a gale. But it is a way of life Mr Mott says he is determined to protect.
