Frequently asked questions
- What special fishing regulations apply at Casco Bay?
- Casco Bay carries 2 special-regulation overlays that override Maine's statewide 2026 rules, covering Striped bass. One of them reads: "Atlantic striped bass 28-31 in slot + 1 / day ASMFC; bluefish + mackerel + winter flounder + Atlantic cod; circle hooks required on natural bait for striped bass since 2021; DMR Recreational Saltwater Fishing Registry required ages 16+." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Casco Bay?
- Yes. Casco Bay is in Maine, so a valid Maine fishing license is required just as it is anywhere else in the state, issued by Maine Department of Inland Fisheries & Wildlife (MDIFW) — freshwater; Maine Department of Marine Resources (DMR) — saltwater. The special regulations on this page change the bag, size, slot, or gear rules for Casco Bay; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Maine rules.
- Do Casco Bay's special rules replace Maine's statewide limits?
- Only where they conflict. Maine's statewide 2026 regulations apply on Casco Bay by default; the overlays above replace the matching statewide rules for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.
- Which species have special rules on Casco Bay?
- Striped bass has a water-body-specific rule on Casco Bay, each linking to its full Maine regulations above. Species not listed here follow the statewide Maine limits.
