Biology

Lesser spotted dogfish or catshark belongs to one of the largest families of sharks, the dogfishes or Scyliorhinidae. Most commonly encountered around the coasts of northern Europe it is a bottom dwelling shark most usually found over sand, mud, algae, and rocky bottoms in coastal waters down to depths of 400 m. Like many elasmobranchs, the catshark often aggregates by size and sex.

In the North East Atlantic females reach first maturity at around 52 cm, with 50% of individuals mature by 57 cm (8 years) and all are expected to be mature by 69 cm. Males reach first maturity at around 49 cm, with 50% of individuals mature by 53.5 cm (6 to 7 years) and all mature 62 cm. Females lay their eggs during spring and early summer. The shark embryos are enclosed in cases (called ‘mermaids’ purses) whilst they develop and mature, a period of 5-11 months depending on sea temperature.

Catsharks can grow up to 1 metre in length, but rarely seen larger than 80 cm. Maximum age is reported as 12 years. They are also marketed as dogfish.
