Trout and friends

In addition to trout, many other fish species like to swim in the Longinoja stream.
- Golly, I’m a gudgeon!
- Ciao, I’m a chub!
- Just a lonely stone loach am I!
- Yikes, I’m a pike!
- Good day, I’m a grayling!
Alongside the endangered trout, many other fish species live here in the Longinoja stream – the same that you can find in the Vantaanjoki river.
- The gudgeon (Gobio gobio) is a small fish in the carp family (Cyprinidae) that lives on river beds.
- The chub (Squalius cephalus) is a stockier member of the carp family that can be identified by its rounded anal fin (behind the belly).
- The stone loach (Barbatula barbatula) is a small fish with barbels around the bottom jaw that lives among the gravel and stones of fast flowing water.
- The pike (Esox lucius) is a predator that eats other fish, including members of its own species.
- The grayling (Thymallus thymallus) is a species of game fish that lives in fast flowing waters. It can be identified by its large dorsal fin that looks like a sail.
- In addition to trout, many other fish species like to swim in the Longinoja stream.
