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.
In the wild these fish gets up to 24 inches (60 cm) in length, though they seldom exceed 12 - 15 (30.5 - 38 cm) in the aquarium. They are fast growing, and have an average lifespan of 10 - 15 years in captivity. In the wild they can live more than 15 years.
