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.
My pond is in its eighth year and since last year some of my original fish have been dying off one by for no apparent reason. I know you can find lots of people on the internet saying that goldfish can live 20 years or more, but I was wondering what length of lifespan you all are seeing in your ponds.
