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.
The mature age of a spottail shiner is around one or two years of age. The maximum age recorded for a spottail shiner to live is 5 years. Since there has not been a lot of research involving the life history of the spottail shiner not a lot of information can be given on spawning and reproduction.
