Habitat
Tench prefer mud-bottom lakes and ponds or the still waters of the lower reaches of rivers where rooted aquatic plants grow in profusion. They are very tolerant of low oxygen saturations and can occur in weak brackish water. Tench can stay alive for a long time when taken out of the water.
Diet
Tench primarily consume aquatic insects, worms, mollusks, and plant matter, often foraging on the bottom for food. They use their barbels to detect and root out prey in murky substrates, and feeding activity is most intense at dawn and dusk. Their diet shifts seasonally, incorporating more vegetation in summer and animal matter in spring.
Behavior
Tench are generally solitary or found in small groups, preferring to hide in vegetation during the day and becoming more active at night or in low-light conditions. They exhibit territorial behavior around feeding areas but are not aggressive, often burrowing into mud to escape predators or during winter dormancy. These fish are known for their resilience, tolerating poor water conditions and surviving out of water for extended periods.
Fishing
This hard fighting freshwater fish takes bait delicately, and as dedicated tench fishermen can attest, they easily become tackle shy. Devoted tench anglers employ a variety of baits including aquatic insect larvae that are the mainstay of their diet. The flesh is soft but tasty and in some areas demands a high price. A muddy flavor can be avoided by keeping the tench alive in clear water for a time after capture
