Recreational anglers and a small number of commercial fishermen can fish for sea bass again in Jersey "under strict requirements", the States says.
Assistant Environment Minister Gregory Guida said a limited recreational fishery had been reopened "in line with the rest of northern Europe" after data indicated "a recovering population".
The species had been suffering a long-term decline in stocks due to over fishing.
Recreational anglers are now being permitted to catch one bass per day while a controlled commercial fishing programme was in place to support local inshore commercial boats to fish for bass "under a strict management system, which includes detailed reporting requirements", he said.
The scheme will also kept under review to monitor its effects on stocks, the States added.
