"In July 2001 RV 'AtlantNIRO' conducted survey on the southern slopes of the Lauzy Bank outside the 200-mile limit in the depth interval from 550 to 1200…..

"Baird’s smoothhead (Alepocephalus bairdii) was fished in depth more than 700 m. Its length was 23-74 cm, mean length of males was 45.2 cm, females 51.7 cm. The length of fish increased with depth of fishing. Weight of fish varied from 83 to 3030 g. Mean weight of males was 774 g, females 1169 g. Males were slightly more numerous than females (sex ratio 1.1:1). The majority of fish (81%) were mature".
The mean of the male and female mean weight is slightly less than 971.50 g.‘Report of the Working Group on the Biology and Assessment of Deep-Sea Fisheries Resources Horta, the Azores, Portugal 4–10 April 2002’More infoMore info.
