A review of the factors influencing spawning, early life stage survival and recruitment variability in the common cuttlefish (Sepia officinalis)
Global landings of cephalopods (cuttlefish, squid and octopus) have increased dramatically over the past 50 years and now constitute almost 5% of the total world’s fisheries production. At a time when landings of many traditional fin-fish stocks are continuing to experience a global decline as a res...
