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.
Goldfish are actually very complex creatures. Amazingly, they can reach lengths of 12 or more inches and live 10 to 20 years. The oldest goldfish on record was over 40 years! Goldfish are among the hardiest of fish, and can survive through the worst of conditions. They are perfectly adapted to life in a pond, just like their wild carp ancestors.
