The opillo-crab season comes to an end, as does the eighth season of “The Deadliest Catch” (Discovery, 8 p.m.) in a two hour episode that includes some critical injuries. It’s followed by an hour long postshow, “After the Catch” (Discovery, 10 p.m.).

Speaking of which, can a proposed open-pit mine for copper and gold co-exist with a wild salmon fishery? It’s examined on a new “Frontline” (PBS, 10 p.m., check local listings).

Fred Willard didn’t get fired from all of his TV jobs. He returns tonight to host a pair of the new improv show “Trust Us With Your Life” (ABC, 9 and 9:30 p.m.), though his own story is probably more interesting than those that will be told by Jerry Springer and Florence Henderson.

The music concentration of “History Detectives” (PBS, 8 p.m., check local listings) continues when someone tries to determine whether his amp was owned by the great Motown bassist James Jamerson.
