Hampshire Carp Hatcheries specialises in breeding and thus producing fingerling fish between one and two years old. Tench are probably one of the slowest growing coarse fish reaching on average 2 – 4 inches in their first year then 4 – 6 inches after a further year of growth. Once they reach this size they tend to accelerate away. The fact that they grow so slowly is reflected in the price – they tend to be one of the more expensive species to rear.
If you wish to stock fish in a fishery and can’t afford to stock the larger fish immediately, then these fish would benefit from further growth in a purpose built and well managed stock pond (see fact sheet).
Tench like warmer water and tend not to feed well until water temperatures rise in to double figures in the late spring. They are brought up feeding on pellets so will have no problem adapting to anglers’ bait. Some fisheries like us to add a few golden tench to the batch to act as markers within the population. This enables the fishery manager to gauge the size of the population by the number of marker fish caught in a season.
