How to catch a spotfin croaker

Bait

Fresh sand crabs (live and soft-shell) — overwhelming favorite. Mussels, clam strips, ghost shrimp as backup.

Rig

High-low with two #4 baitholder hooks, 1–2 oz pyramid sinker, 12 lb mono mainline

Technique

Walk the wash — cast just past the breaking waves where the trough meets the wash zone. Spotfin patrol the back of the wave. Move every 10 minutes if no bite — they cruise.

When to target

Seasonality

Peak fishing late summer through fall (Aug–Nov) when sand crabs are abundant. Spring is hit-or-miss. Winter quiet.

When they bite

Tide preference

Incoming through high — feeds on the rising wash

Time of day

Dawn and dusk strongly preferred

Pressure

Stable

Moon bias

Slight new-moon (surf species)

Seasonality

When to target

Peak fishing late summer through fall (Aug–Nov) when sand crabs are abundant. Spring is hit-or-miss. Winter quiet.

Table fare

If you keep it

Good — mild, white, slightly soft. Better fried or grilled than baked. Bleed at the gills.

⚠ Safety & handling

Before you grab it

Mild dorsal spines, otherwise easy to handle. Watch for hidden weeverfish at your feet when wading.

Common mistakes

What anglers get wrong

Often called 'corbina' by people new to surf fishing — the spot at the pectoral base is the giveaway. Corbina has no spot.

Did you know

Spotfin croakers are one of California's three 'corbina-class' surf trio (the others being corbina and yellowfin croaker). All three target sand crabs, but spotfins are the willing biters — corbinas are the snobs.
