BIOLOGY
Catshark belongs to one of the largest families of sharks, the dogfishes or Scyliorhinidae. Mating occurs from late summer to November, after which females move to spawning grounds in shallower water. The shark embryos are enclosed in cases (called mermaids' purses) whilst they develop and mature (usually around June/July). Females and males mature from 54 to 60 cm in length at around 5 years of age. Catsharks can grow up to 1m in length, maximum age is unknown. They are also marketed as dogfish.
ADVICE
Catsharks are one of the few shark species whose numbers appear to be stable at present. In general consumers should avoid eating shark species as they are vulnerable to over-exploitation due to their specific biological characteristics (slow-growing, late to mature and generally produce few young).
