Because the FHSS systems are using much (or all) of the band, there are situations where they can be badly affected while a DSSS system is not affected at all. This can occur if the band is heavily congested except for a small portion and the DSSS system chooses that portion on which to operate.
Spotted seatrout (specks) in Louisiana seldom survive past age 5, tunas are old at age 12, and redfish may live about 40 years at the maximum. The oldest red snapper reported in the scientific literature is an individual sampled in February 1991.
Like the maximum size, the lifespan of goldfish is also variable. The record is 43 years, but it is uncommon for goldfish to live this long. Goldfish usually live quite long when kept in large aquaria or outdoor ponds, up to 15 to 20 years is not unheard of. In smaller or heated aquaria, a lifespan of five to ten years is quite achievable.
