Description and behaviour
The tench is one of the most secretive fish of still waters — weedy lakes, ponds, peat pits and quiet backwaters where the water warms slowly and the bottom is carpeted with soft silt.
This fish is markedly warmth-loving and bottom-dwelling: the tench spends almost all its time right on the bottom among stands of pondweed, lilies and reeds, rarely rising into the water column. When the temperature drops or oxygen runs short it can bury itself in the silt and fall into a torpor, which makes it remarkably hardy in closed waters with no outflow.
The tench feeds on bottom invertebrates, insect larvae, molluscs and plant detritus, searching for food deep in the silt and among the roots of water plants. Its characteristic thick, slimy skin protects it from injury as it moves through dense weed and snags.
Spawning and seasons
The tench spawns late compared with other carp species — from late May through July, once the water has warmed steadily to 19–20°C, and it spawns in several batches with breaks in between.
During spawning and immediately afterwards the tench stays in the thickest weed over the shallows and barely reacts to bait — the bite all but stops in this period.
The main fishing season opens in June, once the water is warm enough for active feeding, and runs to late August or early September. As the water cools the tench sharply reduces its activity, and by autumn it stops feeding altogether, settling into the silt to winter until the following spring.
When it bites
The best time for tench is the early morning, in the first hours after dawn, when the water by the weeds still holds the cool of the night and the fish move out to feed over shallows warmed through the previous day. A second, less pronounced feeding spell comes on before sunset.
In the heat of midday the tench usually stands motionless in the shade of the weed and takes sluggishly — on many peat pits and weedy ponds the daytime bite all but stops.
The fish feeds more steadily in warm, windless weather with a light haze, or after a warm rain has freshened the water. A sharp cold snap and swings in atmospheric pressure noticeably knock back the tench's activity for a day or two.
Methods and tackle
The classic tench rig is a whip or Bolognese float rod of 4–6 m with fine line of 0.14–0.18 mm and a sensitive float carrying 1–2 g, enough to show up the cautious, often barely visible bite.
You fish right at the edge of the weed, in windows of clear water among the lilies and along the reed line — that is where the tench searches for food in the morning hours. Cast accurately and without unnecessary noise: the fish is very sensitive to vibration and any splash at the surface.
On the more open stretches of ponds and old pits a light feeder with a small cage and a soft, sensitive quivertip works well — the tench takes the bait unhurriedly, and on coarse tackle the take often goes unnoticed by the angler.
Baits and lures
The main tench bait is a large brandling worm or a bunch of small worms presented straight on the bottom at the edge of the weed; through the colder part of the season an animal bait is the most reliable.
Maggot also does well, as does its combination with worm — a "sandwich" that draws fish by both scent and movement. As the water warms the tench readily takes plant baits too: stewed pearl barley, paste and small soft boilies.
Groundbait for tench should be fine and dark in colour, matched as closely as possible in smell to the silty bottom — use breadcrumb, oilcake and a little chopped worm, with the bare minimum of harsh flavourings, since this wary fish avoids strongly scented mixes.
Playing and landing
A tench bite often looks like a slow, insinuating dip of the float — there is no need to rush the strike; better to wait for the antenna to slide confidently under.
Once hooked the tench puts up a dogged but not violent resistance, trying to reach the nearest weed; it is important to lead the fish gently and without jerks away from the weed towards clear water straight away.
Because of the dense slime on its body the tench is best handled with wet hands or through the mesh of a landing net so as not to damage the skin. Good tench swims on weedy lakes and ponds are worth remembering and baiting up in advance — the tench is a creature of habit and holds for a long time to the same silty spots.
