Use more data sheets if needed for one fishing event
– Make it Clear that this is the same angler and fishing location
Fish for a minimum of 30 minutes at a given Location.

How Much To Fish?
• As much as possible try to:
Target Mud, Natural Reef and Restored reef Equally
Visit at least one of each type of site on every fishing trip.
We need multiple fishing events (samples) at EACH location
(1-9) during each season.
This is not a one person study, this is a team effort.
Coordinate with CCA to target areas so that fishing effort
is evenly distributed amongst sites.
CCA will reimbursed Bait cost. Turn in your data with your
receipt to get reimbursed.

Thank you!
