Reproduction Preferences Additional InformationGobius couchi has a life span of up to 6 years (Miller, 1986).
Very little information is available detailing the reproduction of Gobius couchi, but it is probable that this is fairly similar to that of other Gobiidae. For instance, Gobius cobitis, Pomatoschistus microps, and Pomatoschistus minutus usually produce 2 clutches of eggs each breeding season. Eggs are laid by the female and attached to the under-surface of large boulders or shells. The eggs are then fertilized and guarded by the male. Thus the eggs are protected and kept inshore until the feeding larvae hatch. The breeding season usually occurs in spring and early summer in Britain. Fecundity will probably vary between 2,000 and 12,000, within the same range as that of other Gobiidae.
