Haddock is a slender fish, fairly grey in colour - they can also have shades of purple or greenish brown on their body.
They are easily identified by the black line that runs the length of them from gills to tail.
They live in The Atlantic and The North Sea.
Haddock spawn in mid to late Spring and are best to be avoided at this time. Haddock return to the best after they have spawned so best enjoyed between May through to February.
It eats small invertebrates and larger haddock have been known to eat other fish.
They get to roughly 40-60cm
