Fish (Books)

Dogfish
"But he [Toothless] came back when Hiccup called, eventually, and by the end of a couple of hours he had caught six medium-sized mackerel and a dogfish"

- Book 1

Herring
Herring are mentioned in How to Train Your Dragon when Hiccup feeds Toothless kippers. Kippers are herring that are split lengthwise, preserved (salted or pickled), and then smoked.

Mackerel
Mackerel are mentioned in the first book when describing the smell of dragons. The Dragon Nursery is described as smelling of "the stench of dragon - a salty stink of seaweed and old mackerel heads", in Book 1.

"If you catch me a nice big mackerel you will be the cleverest, fastest dragon on Berk AND you will make that Fireworm dragon look like an idiot AND you will have all the lobsters you can eat when we get home AND I will tell you a really good joke."

- Hiccup to Toothless in Dragonese

"Hiccup had gotten bored and was looking for oysters when Toothless came bursting triumphantly out of the sea carrying a small mackerel."

- Book 1

"But he [Toothless] came back when Hiccup called, eventually, and by the end of a couple of hours he had caught six medium-sized mackerel and a dogfish"

- Book 1

Piranha
Piranha are mentioned when Gobber describes what will happen if the Viking Novices wake up the dragons hibernating in the Dragon Nursery. "Dragons this size are normally fairly harmless to man, but in these numbers they will set upon you like piranhas. There'd be nothing left of even a fatso like you, Wartihog - just a pile of bones and your helmet."

- Gobber
