The reproductive cycle of Ophichthus rufus (Pisces: Anguilliformes) in the NW Mediterranean

The reproductive biology of the Mediterranean Snake cel, Ophichthus Rufus (Ophichthidae), was studied on the basis of microscopic and macroscopic analysis. Results show that O.rufus is an oviparous species with a group synchronous ovary type. The maturation process of the gonads starts in December and progress until August, when ovulation and a pawing take place. It is a fractional spawned with buoyant eggs. Potential annual fecundity estimates ranged from 1426 to 23.605 oocytes. Except for small sizes, a clear predominance of females was observed
