We've just restocked the middle pool (Mr Crabtree) with 500 tench, been a slow year this year for the tench so we thought we'd freshen it up with some new bars of Soap.
Popped 500 of the little beauties in and they've got the winter months to settle in.
We'll be feeding them up over the winter months and look forward to seeing what catches you get in the coming years.
Tench and a little guide
Tench are easily recognizable thanks to their distinctive look. They have a slender, elongated body covered with smooth, dark greenish-brown to olive-green skin that shines in the light.
These fish can grow up to 50 cm (about 20 inches) in length and typically weigh between 2 to 8 lbs). However, some record-breakers have been spotted weighing over 13 lbs, showcasing their potential size. The British record stamds at 15lb which was caught by David Pratt on a midlands still water.
Their relatively small and rounded fins enhance their swimming capabilities. The most striking feature is their large, fleshy lips, enabling them to forage effectively on the bottom of their habitats.
This body structure, alongside their coloration, not only helps them blend in with aquatic plants but also aids their specialized feeding habits.
Habitat and Distribution
Tench thrive in freshwater environments, including lakes, ponds, and slow-moving rivers. They prefer warm, shallow waters dense with vegetation, which provide shelter and breeding areas.
Highly adaptable, tench have established populations in various locations across Europe and Asia. Interestingly, they can also be found in specific regions of the UK, expanding their range even further.
Typically, you can find them at depths of 3 - 6 feet but they also venture into deeper waters during warmer months to escape rising temperatures.
These fish favor habitats with soft, muddy bottoms where they can dig for food using their unique mouth structure.
Diet and Feeding Habits
Tench are primarily omnivorous, with a diet rich in various food sources. They consume insects, crustaceans, small fish, and aquatic plants.
Their foraging style is quite unique; they uproot plants while searching for delicacies at the bottom of water bodies. This method displays their important role in maintaining aquatic ecosystems.
Peak feeding activity occurs at dawn and dusk, making these the ideal times for anglers to cast their lines. Research shows that fish activity can increase by as much as 50% during these hours.
These fish also possess a slow metabolism, allowing them to withstand longer periods in nutrient-poor waters. This ability gives tench an advantage when food sources dwindle.
Breeding and Reproduction
The breeding season for tench occurs in spring and early summer when water temperatures exceed 18°C. During this time, male tench become more territorial, displaying aggressive behaviors to deter rivals.
Nesting typically takes place in shallow waters, where females can lay thousands of eggs amid lush vegetation. Under optimal conditions, these eggs hatch within one week.
Interestingly, newly hatched fry are black and stay close to the substrate for safety. As they grow, they gradually venture into deeper waters, continuing their development.
Maturing tench exhibit notable changes in physical appearance, particularly in males, who develop more vibrant colors, enhancing their appeal during mating season.
Tools and Techniques for Catching Tench
For those keen on catching tench, utilizing effective fishing methods is vital.
Bait Selection: Soft baits like sweetcorn, worms, and specialized tench pellets have proven successful.
Fishing Techniques: Float fishing and method feeder techniques yield great results. It is best to fish close to the bottom, as tench often forage near the substrate.
Optimal Times: As previously mentioned, dawn and dusk are prime times for fishing, with tench active during these hours.
Location: Look for areas with abundant vegetation or near the edges of lakes and rivers, as tench frequently forage for food there.
Patience plays a crucial role in fishing for tench; these cautious fish often nibble before fully taking the bait.
Conservation Status and Threats
Despite their adaptability, tench populations face several environmental threats. Urbanization, pollution, and the introduction of invasive species can disrupt their natural habitats.
Although tench are generally regarded as a stable species, local populations may fluctuate. Protecting their habitats through conservation efforts and responsible fishing practices is essential.
Tench are important to their ecosystems, making it vital to practice catch-and-release fishing. This not only helps maintain healthy tench populations but also promotes ecological awareness among anglers.
