Habitat
It inhabits the eastern United States and Canada, from Nova Scotia southward through all of the Atlantic coast states and most of Florida, and westward through Georgia, Alabama, and Louisiana to as far as the Navasota River in eastern Texas. From Louisiana, it extends northward in the Mississippi River drainage through eastern Arkansas to southeastern Missouri and southwestern Kentucky.
Diet
Picuda primarily feeds on smaller fish, crustaceans, and insects, using its sharp teeth to ambush prey in fast-moving waters. It hunts actively during dawn and dusk, often in schools to corner smaller organisms. Feeding behavior includes swift chases and surface strikes.
Behavior
Picuda are schooling fish that exhibit aggressive and territorial behavior, particularly in defending feeding areas in rivers. They are diurnal predators, most active during low light periods, and known for powerful jumps when hooked by anglers. This species migrates upstream during the wet season for spawning and can be solitary or group-oriented depending on food availability.
Fishing
Anglers targeting Picuda (Salminus affinis), a hard-fighting sport fish in South America's rivers, should focus on aggressive techniques like trolling with diving lures, casting spinnerbaits, or fly fishing with streamers to imitate their prey of smaller fish and crustaceans, capitalizing on their ambush-style strikes. Use medium-heavy spinning or baitcasting rods paired with reels spooled with 20-30 lb test line and strong hooks to handle their explosive jumps and powerful runs; effective baits and lures include live minnows, crankbaits, or spoons that mimic natural forage. The best season is during the rainy months for spawning migrations, with prime fishing times at dawn and dusk when they are most active in fast-moving waters; target them in rivers like the Magdalena and Santiago in Ecuador, focusing on deep pools, riffles, and current breaks where schools form. Picuda can reach up to 11 pounds and 40 inches, with the IGFA all-tackle world record around 11 pounds, underscoring their status as a thrilling catch. Conservation-wise, angler-funded programs through license fees support habitat protection in these waterways, and practices like catch-and-release help maintain stable populations, making regulated fishing a key tool for preserving this species in its South American habitats.
