Introduction to the technique

Bottom fishing is vertical or nearly vertical fishing practiced from a boat to target fish holding on the bottom or just slightly above it. It is not a “simple” technique in the trivial sense of the word: the real difference is made by drift control, reading the bottom, and the ability to keep the bait in the right strike zone without making it drag unnaturally. There are different forms of bottom fishing, from light inshore styles to medium-deep and all the way to deep bottom fishing, and each requires small variations in tackle and setup. Classic catches include pandora, rudd, bottom-feeding gilt-head bream, common pandora, various sea breams, conger eels, scorpionfish, and dentex, but the technique will intercept anything feeding close to the bottom.

When to practice it and why

Bottom fishing produces all year round, but fish behavior changes greatly depending on water temperature, light, current, and fishing pressure. In spring and autumn there are often excellent windows because many species feed steadily and occupy accessible depth ranges; in summer it pays to focus more on dawn, dusk, and nighttime hours, while in winter slower, more precise fishing near ledges and mixed mud bottom is often rewarded. Seas that are too rough make it difficult to stay effectively fishing, but a slight drift and a bit of movement can help because they bring the bait to life and make the rig work better. After a tide or current change, or when the wind realigns with it, short but very productive moments often occur: bottom fishing rewards those who know how to recognize these windows.

Reading the spot

The bottom should not be chosen “at random,” but interpreted. The best areas are changes in bottom composition, for example the transition from sand to rock, small ledges, humps with gentle edges, channels, and flat areas dotted with scattered stones: this is where food concentrates and predators patrol. With sonar and GPS, do not look only for marked fish, but above all for structure: a rise of just a few feet, a crack, or a strip of debris can be worth more than a school seen suspended in the water column. A typical sign not to underestimate is “empty water just above the bottom” with a few echoes slightly detached: it often indicates fish lying on the bottom or suspended just a little above it, exactly the ones reachable with a well-adjusted rig.

Well-thought-out tackle

For inshore bottom fishing, short and sensitive rods are excellent, generally between 1.8 and 2.4 meters, capable of reading the sinker on the bottom while also handling important fish. The reel must have smooth retrieve, progressive drag, and good line capacity; more than size, what matters is reliability under strain and the ability to drop and retrieve often without causing fatigue. Braid offers contact, sensitivity, and a quicker hookset in depth, while monofilament is more forgiving and absorbs jolts better: many anglers use braid on the spool and a fluorocarbon or nylon leader to combine sensitivity and natural presentation. The sinker should be chosen not only for “how much depth there is,” but to stay as vertical as possible with the minimum weight that still allows control: too light and it drifts off, too heavy and it stiffens everything and kills the bites.

Rigs and variants

The most classic rigs are the paternoster with droppers above the sinker, the flag-style rig, bottom-fishing rigs with backbone line and swivels, and more essential one-hook versions for wary fish or snaggy bottoms. Relatively short droppers help with control and reduce tangles on rough bottoms or with sustained drift; longer droppers provide more natural presentation when fish are suspicious and the sea is calm. On rock and ledges it is often better to reduce the number of hooks: you fish cleaner, snag less, and understand the bite better. For dentex, large red porgies, or fish that strike just off the bottom, a rig that keeps the bait slightly lifted from the bottom can be more effective than the classic “sinker planted and low droppers” setup.

Baits and presentation

The bait must be fresh, compact, and rigged so that it works well on the drop and during controlled drift. Squid, cuttlefish, shrimp, sardine, bloodworm, Korean worm, and fish strips are great classics, but the choice should be tied to the target species and the presence of bait stealers: on bottoms infested with small fish, a larger, firmer bait lasts longer and selects better fish. Presentation matters as much as the bait itself: a crooked bait spins on itself, twists the dropper, and looks unnatural; a straight baiting, with the hook well exposed, fishes immediately better. One often decisive detail is alternating stillness and small movements: two or three short taps with the rod tip, then a pause, imitate a live morsel without moving the sinker too far from the productive zone.

Boat management and fishing action

In bottom fishing, the boat is part of the tackle. You need to drop in such a way as to arrive on the spot with the line as vertical as possible, correcting the drift and making repeated passes over the same stretch if it produces bites. If the sinker loses bottom or the line opens up too much, you are no longer really fishing: it is better to retrieve, realign, and start again than to drag the bait out of the zone. Bites can be sharp or barely hinted; often a violent hookset is unnecessary, and a simple progressive tightening accompanied by the retrieve is enough, especially with sharp hooks and thin leaders. When an area produces a fish, it is rarely by chance: marking the exact point and the angle of the drift is one of the habits that truly makes you improve.

Common mistakes and corrections

The most widespread mistake is fishing too heavy and too stiff, thinking it will help you “feel better”: in reality, it reduces natural presentation and sensitivity to subtle bites. Another classic mistake is insisting on a uniform bottom with no reference points, whereas bottom fishing performs better on details, even tiny ones, that concentrate life and food. Many beginners strike instinctively at the first vibration and pull the bait from the mouth of wary sea breams; instead, it is better to distinguish between nibbling and a true run, maintaining contact and waiting for the weight of the fish. Maintenance also matters: hooks that are not perfectly sharp, worn knots, leaders that have turned dull or become curled cost more fish than people think.

Trade secret

One underrated trick is using the “controlled lift” when the bottom seems empty. After touching bottom, raise the sinker a few decimeters and fish there for a few minutes: many fish, especially sea breams and active dentex, do not stay glued to the bottom but slightly above it, where they see the bait better and attack it more decisively. If you alternate brief pauses on the bottom with pauses just off it, you can often understand in only a few drops at what height they are feeding that day. The other advantage is practical: fewer snags, a cleaner rig, and a bait that works in a much more visible way, especially on mixed bottoms or with small tufts of seagrass.
