The pejerrey is a medium-sized fish with a delicate mouth, so the tackle leans to the fine and sensitive side. A recommended setup:

• Rod: light action (light / ultralight), from 1.80 to 3.00 m depending on the method. For float fishing from shore a longer rod helps to cast and to register the bite; for spinning with micro-lures, a short, sensitive fast-action rod. A soft tip is key to cushioning the fragile mouth.
• Reel: small spinning reel (size 1000 to 2500) or a light baitcaster, with a smooth, well-adjusted drag. The smoothness of the drag prevents the mouth from tearing during the fight.
• Main line: fine nylon of 0.20 to 0.25 mm, or light braid (4 to 8 lb) for spinning, which gives maximum sensitivity to detect the subtle bite.
• Leader: nylon or fluorocarbon finer than the main line, 0.18 to 0.22 mm. Fluorocarbon is less visible underwater and helps in clear water.
• Hooks: small and of good quality, matched to the pejerrey's reduced mouth; staggered on the line to gauge depths.
• Accessories: fine, sensitive floats or corks, light sinkers to regulate depth, and a soft mesh net if you are going to release fish, to handle them with the least possible harm.

The philosophy of the tackle is simple: the finer and more sensitive it is, the more bites you will detect and the more you will enjoy the fight of this silver fish.

The gear must measure up to a strong fish that runs, jumps, and lives in current with structure. Specific recommendation:

Spinning (standard setup)

• Rod: spinning rod of 1.80 to 2.10 m, medium to medium-fast action and medium / medium-heavy power, with a good response for setting the hook in a hard mouth.
• Reel: a sturdy spinning reel size 3000 to 4000, with a progressive, reliable drag to hold up to the runs.
• Line: braided line of 20 to 30 lb; it gives sensitivity, low stretch for a solid hookset, and the load capacity for big fish.
• Leader: an anti-cut leader is essential because of the teeth: thin flexible steel (coated steel cable) or heavy fluorocarbon of 40-60 lb. Without it, the dorado cuts the line with a single bite.

For trophy specimens or big rivers: step up to a medium-heavy/heavy rod, a 4000-5000 reel, and 30-40 lb braid, with a steel leader.

Fly fishing

• Rod: #8 to #10, fast, to move large streamers and fight in current.
• Reel: with a good disc drag and backing capacity.
• Line: WF (weight forward) matched to the rod number; in fast water a sinking tip may be advisable.
• Tippet / leader: finish with an anti-cut section of steel or heavy fluorocarbon, just as in spinning.

Key accessories: strong, well-sharpened hooks (ideally barbless if you're going to release), long pliers to unhook without hurting yourself on the teeth, and if you practice catch and release, a knotless/rubber net and gloves to handle the fish carefully.
