overview

who is the crucifix sea catfish

The uritinga is a marine catfish that lives mainly in estuaries and brackish lagoons, from Colombia to Brazil, and also goes up into fresh water. It stays over shallow mud bottoms and eats fish and shrimp. It exceeds 1 m and 9 kg, but the usual size is 40 to 60 cm. It lives three to four years, matures between 1.5 and 2 years, and breeds from November to April. In Pará and Maranhão it is a common catch on longlines, bottom lines and gillnets, and amateur anglers find it in mangrove channels and bays, using fish or shrimp bait, especially at night. It is sold fresh.

fun facts

  • The cleaned skull, with the crucifix pattern on the underside, is sold worldwide as a souvenir and amulet.
  • FishBase records that it grows more slowly in two dry periods of the year, in March and from August to November.
how to recognize it

identification

Somewhat flattened head, mouth on the underside and three pairs of barbels (one at the corner of the mouth and two on the chin). Dark grayish back and pale belly; serrated spines on the dorsal and pectoral fins. Nape bony plate with a notch at the front and a small rear chamber of the swim bladder, which separates it from the gurijuba. The cleaned skull shows, on the underside, a pattern resembling a crucifix.

Caught all year. Breeding runs from November to April; in the dry season of the second half of the year, saltier water draws the catfish into the estuaries.

best time of day

Night and twilight. Most active at night and in murky water; by day it bites on the bottom of channels and holes.

weather, water and behavior

what affects the crucifix sea catfish
sensitivity The little bars show how much each factor affects this species. Five full: it feels it a lot.

cold and cold fronts

No significant effect on the equatorial coast.

atmospheric pressure

Not very sensitive.

moon

Spring tides at new and full moon increase the current and activity in the channels.

rain

Adapted to muddy water; rain doesn't bother it.

water level

It follows the saltwater wedge: in the dry season it moves further up the estuaries.

noise

Not very sensitive to murky water.

wind

Strong wind bothers the boat more than the fish.

tide

Fish the ebb at the mouths of igarapés (creeks) and mangrove channels.

depth

1 to 10 m, in channels and holes.

accessories

  • pliers and gloves
  • damp cloth to hold the fish

tip from an angler

Fish the ebb at the mouths of igarapés (creeks) and mangrove channels, with enough sinker to keep the bait still on the bottom.

what the law says

rules for the crucifix sea catfish

Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not assessed by the IUCN, according to FishBase. Not on the national list (Portaria GM/MMA 1.667/2026). We found no specific federal rule for the species.

We found no species-specific rule beyond the region's general rules.

catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.

The serrated spines of the dorsal and pectoral fins puncture and cause infection: use gloves and pliers, hold the fish from behind the spines and release it horizontally, in the water.

in the kitchen

Firm, tasty flesh, eaten fresh in the North in caldeiradas, roasts and moquecas.
