Piked dogfish

The Piked dogfish or Spurdog is probably the most successful shark species worldwide, as it is found in most seas in relatively large numbers. Individuals usually measure between 50 and 110 cm in length and weigh around 1–3 kg, although they can grow larger, exceeding 150 cm and reaching up to 9 kg. Its reproduction takes place during the winter. It is caught using bottom trawls, static nets, longlines, and vertical lines.

This is a benthopelagic shark species that typically inhabits depths between 5 and 150 meters, although it has been recorded at depths exceeding 1000 meters and can also tolerate brackish waters. It is a social species, often forming groups based on size and sex, though mixed aggregations may appear seasonally. During gestation, which lasts approximately 22 months, the female carries the eggs inside her body. Each female can give birth to 1 to 20 offspring (ovoviviparity). The newborns are self-sufficient and fully independent from the very first moment of their lives, and their size ranges from 18 to 30 centimeters. Its diet, like that of most sharks, is varied, but due to its small size, it is limited mainly to small bony fish, crustaceans, gastropods, cephalopods, and jellyfish. 

It is recommended to avoid as elasmobranchs are generally vulnerable, and although this species is doing well, overfishing it will make things difficult. It is always recommended to ask your fisher or fishmonger where the fish was caught and with which fishing method, as well as buying this species outside of its spawning period. Prefer locally harvested seafood products by coastal small-scale fisheries.
