Leuciscus idus



Is it a Dace? Is it a Roach? Is it a Hybrid? No. It’s an Ide! This little Scandinavian species is not natural to British waters and has been bred by British fishery owners. The Ide shares its body shape with a Chub and look very similar when young, it has a small head and has large eyes with a yellow tinge to its iris. The dorsal fin of an Ide is a greyish blue in colour where as the other fins have a reddish colour. With a greenish colouration to its back and a greyish blue down the flanks this small scaled fish is very pleasant to the eye.


As they are an introduced species UK records are not recorded. The average size of an Ide within the UK is between 12oz and 2lb, there are records of some UK fisheries stocking Ide in excess of 4lb. Within the Ide’s natural environment it has been knows to reach sizes in excess of 10lb.


Records show that the average length of an adult Ide will be around 30cm to 40cm from tip to tail.


The Ide will live a fair length compared to other species. The average lifespan for an Ide will vary from 10 to 15 years in the right conditions.


The Ide inhabits the lower reaches of clear large rivers, lowland lakes, and brackish estuaries of rivers. It schools in clean, deep water, moving into shallow freshwater to spawn. Ide will spend a lot of their time at the top of the water and will swim around cover such as weeds and banks.


The Ide is a surface dwelling shoaling fish and are not fussy when it comes to food.


Similar to a chub, this species will sample anything. Their natural diet will contain a variety of aquatic larvae and insects. Being up in the water fish, an angler will benefit from using a pole fished shallow in the water. Worm and casters are common baits for Ide in the summer months where as maggots are well used within the colder times of the year.


Ide will commonly reach sexual maturity between the ages of 3 to 5. In areas such as Finland they tend to mature later in life, around 7 years of age. It has been recorded that the males are on average three cm shorter in length than the females at the time of sexual maturity.


Spawning starts around April to June. The ideal temperature is anything between 5 to 14 degrees. Ide will lay their eggs within sandy or weedy shallow areas where the eggs will sit on gravel and plant life.
