Cast netting: Recreational cast netting for shrimp is
permitted during the Louisiana inshore waters shrimp
season only. Cast nets must be less than 8.5 feet in radius.
The daily shrimp limit is five gallons of heads-on shrimp
per day, per vehicle or boat. Cast netting for bait is
permitted year round. The shrimp limit, when cast netting
for bait outside the Louisiana inshore waters shrimp
season, is one gallon per day per vehicle or boat. Cast
netters must maintain actual custody of shrimp while on
the refuge.
