Tench
Tinca tinca
The tench — 丁桂鱼 — is Eurasia's olive, red-eyed still-water carp: a thick-skinned, slime-coated bottom feeder of weedy bays, native across Europe and northern Asia — in China only to Xinjiang's Irtysh and Ulungur waters — and introduced to southern British Columbia, where it is established in Okanagan lakes such as Christina and Osoyoos.

Identifying features
- Deep, olive-green body with a thick coat of slime over very small scales
- Small, round, red-orange eyes — unmistakable up close
- Rounded fins, a thick caudal peduncle and no sharp spines
- One small barbel at each corner of the mouth
- Males have noticeably longer, curved pelvic fins that reach past the vent
Habits
- Eurasian species; in China native only to still bays of Xinjiang's Irtysh system and Lake Ulungur, with introductions elsewhere
- Feeds on the bottom on insect larvae, snails and plant matter, often at dawn
- Loves dense weed and soft mud, digging pits in the silt while feeding
- Shy and slow-growing; most active in warm, calm summer weather
- Spawns in summer, scattering sticky eggs over weeds in shallow bays
Distribution
Where to find them
- Weed edges in still bays of Ulungur and Irtysh backwaters
- Dawn feeding pits in soft mud beside reed beds
- Quiet corners of stocked still waters
Where they live
How to catch them
Still-water bottom fishing with corn and bread Lake
Rig: Ledger or method-feeder rig on a clear spot beside weeds, baited with corn, bread or small pellets in European carp style
Bait/lure: Sweet corn, bread, pellets
Key tip: Pre-bait a clear patch at dawn for several days; tench are shy and visit baited spots early before other fish arrive.
Float fishing at dawn near weed Lake
Rig: Light float rig laid overdepth beside reed and lily edges, bait resting on the bottom
Bait/lure: Worms, corn, maggots
Key tip: Watch for the classic tench bubbles and tiny float lifts at first light; strike at the second, firmer movement.
Best baits & lures
Baseline setup
- Rod: Medium 10-12 ft float or feeder rod
