Laboratory culture and estimated life span of the Eastern Atlantic squid, Loligo forbesi Steenstrup, 1856 (Mollusca: Cephalopoda)

Laboratory culture and estimated life span of the Eastern Atlantic squid, Loligo forbesi... Abstract. First culture results are presented from four major experiments (lasting up to 478 days) on the commercially important squid species, Loligo forbesi Steenstrup, Details are provided on eggs, hatching, feeding, growth, survival, behaviour and sexual maturation. Best survival during the critical first 75 days was 15%. The hatchlings (up to 4.9mm mantle length, ML) are the largest among the genus Loligo, and the largest squid grown was a male 155mm ML and 124g. First schooling was observed only 40–50 days post‐hatching. Spawning was not achieved although males reached maturity, females had maturing ova and mating was observed. The largest giant axon measured was 425μm in diameter (from a female 130mm ML), a size suitable for most biomedical applications. Laboratory data suggest a 2‐year life cycle compared to fishery data which suggest a 1‐year cycle. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aquaculture Research Wiley

Laboratory data suggest a 2‐year life cycle compared to fishery data which suggest a 1‐year cycle.
