Serra Spanish Mackerel
The Serra Spanish mackerel is Brazil's own species of Spanish mackerel — native to the western Atlantic from the Caribbean south to Rio Grande do Sul.
It's a cornerstone of artisanal coastal fisheries, especially in the Northeast, where year-round availability makes it one of the most commercially and recreationally important pelagic fish along the Brazilian coast.
Scientific Name: Scomberomorus brasiliensis
Also known as Serra, Cavala, Scomberomorus brasiliensis
- Elongated, strongly compressed silver body with a pointed snout and a widely split mouth lined with small, sharp teeth — built for speed and cutting through baitfish schools.
- Rows of bronze-yellow spots along the sides; lateral line curves gradually down toward the tail rather than dropping sharply — the key visual difference from king mackerel.
- Forked, tuna-style tail with a single keel and two lateral ridges on the caudal peduncle; no scaled corselet on the pectoral fins.
- Common fish run around 65 cm; maximum recorded length is 125 cm and just under 7 kg, though most fish caught by anglers are well under that.
What to know
Habitat Distribution
- Native to Brazil — found along the entire Atlantic coastline from the mouth of the Amazon south to Rio Grande do Sul, with the heaviest concentrations in the North and Northeast.
- A reef-associated, oceanic traveler: moves through coastal and offshore waters, often over or near reefs, rocky outcrops, and structure that concentrate baitfish.
- Tropical to warm-temperate waters; the species range runs from roughly 21°N to 36°S in the western Atlantic.
- Year-round availability in northeastern Brazil makes that stretch — states like Ceará, Rio Grande do Norte, and Pernambuco — the heart of the Brazilian fishery.
Key Locations
- Northeastern Brazil (Ceará, Rio Grande do Norte, Pernambuco) — the core of the artisanal fishery, with year-round availability and the highest documented landings.
- Northern Brazil and the Belém market area — the holotype specimen was collected here, and the region has a long history of serra fishing.
- Southern Brazil coast down to Rio Grande do Sul — the southern limit of the species' range; fish are present but less consistently than in the Northeast.
Specific Spots
- Reef edges and rocky outcrops concentrate baitfish, which pull serra in tight — work the up-current face of structure where fish can intercept prey without burning energy.
- Surface and mid-water over shallow coastal reefs, especially when baitfish schools are visible or birds are working overhead.
- Current lines and color changes offshore where warm water meets upwelling; serra use these thermal edges to corner prey.
- Near the surface early and late in the day; they push baitfish to the top in low-light conditions, making them visible and catchable from boats or piers.
Serra Spanish Mackerel FAQ
Answers from onWater's species guide.
What are the best lures and bait for Serra Spanish Mackerel?
Trolled or cast metal spoons and slender hard-bodied minnow lures in silver or sardine patterns are the go-to across the Brazilian coast, match the size to local baitfish, typically 8–15 cm.
What flies work for Serra Spanish Mackerel?
Clouser Minnows (weighted flies that imitate baitfish) in white, chartreuse, or silver are the most practical choice, they sink fast, cast well in wind, and profile like the sardines and anchovies serra are chasing.
When is the best time to fish for Serra Spanish Mackerel?
Northeastern Brazil: available year-round, with fishing effort sustained across all months, no hard off-season. Southern Brazil: more seasonal presence, with fish appearing in warmer months as water temperatures rise along the coast.
How do you catch Serra Spanish Mackerel?
Most fishing for serra in Brazil happens from small open boats, either trolling lures and rigged baits along reef edges and current lines, or casting to visible surface-feeding schools. Shore and pier fishing with cast metal lures is also common in the Northeast wherever fish push baitfish close to the coast.
What do Serra Spanish Mackerel eat?
Small fish are the primary food, sardines, anchovies, and other schooling baitfish make up the bulk of the diet. Matching a slender silver lure or a Clouser Minnow (a weighted streamer that imitates a baitfish) to the size of local bait is the most reliable starting point. Squid and shrimp round out the menu.
