Life History Strategy of Maurolicus muelleri (Gmenlin, 1789) in the Bay of Biscay

Maurolicus muelleri is a significant component of the marine ecosystem and has potential to be valuable fishery resource. However, in Bay Biscay, its primary biological traits remain unclear. This study presents data on length distribution, age, growth, maturity ogive, spawning season, batch fecundity, sex ratio for captured Biscay. The results showed that spring, adult spawners (ages 1 2) were dominant catches, while September, immature juveniles (age 0) born spring mostly found. Using standard lengths as basis, 50% fish mature at 34.1 mm (both sexes combined), ratio, male female, was 0.44:0.56. proportion females increased with length, 1:1 predicted 41.5 mm. season allocated least between March likely peak May. fecundity ranged from 114 919 oocytes/female, weight females. allowed us interpret life history strategy this species, i.e., high females, which participate one or two reproductive seasons. Therefore, any possible exploitation age 0 prior could lead decrease population recovery slow.
