Fish haven / artificial reef
DangersRegional
A fish symbol identifies an artificial reef or fish-haven obstruction.
What it means
The fish-haven symbol marks deliberately placed material intended to attract marine life. The chart may add an area limit, obstruction legend, or least depth.
Why it matters
Treat charted depth and clearance information as decisive. Do not infer a guaranteed clearance from the fish symbol alone.
