Short-finned squid landed by the French fishery are by-catch of trawlers operating in the Northern Bay of Biscay and Southern Celtic sea. In the period November 1997–June 1999 samples of commercial specimen were collected monthly. A total 1065 Todaropsis eblanae were analysed for biological parameters. In a subsample of animals age was determined using statoliths. Mature animals are observed almost all year round, however juvenile recruitment occurred mainly in winter and sexual maturation increased in spring. Size at sexual maturity (DML 50) was 16.5 cm in females and 13.5 cm in males. Length frequencies showed that the range of exploited stages was 9–29 cm in females and 8–22 cm in males. Statolith analysis indicated that youngest recruits were about 4 mo old and that growth was faster in females than in males (3.41 and 1.86 cm mo−1, respectively). Sex-related differences in growth and size at maturity are in agreement with previously published data from the Galician coast.
