After 12 seasons and counting, "Deadliest Catch" gets its own spin-off.
"Deadliest Catch: Dungeon Cove" (9 p.m., Discovery, TV-14) follows four families striving to make a living and stay alive while hunting down Dungeness crab in a dangerous stretch of Oregon coastline.
- The five-part series "Taking Fire" (10 p.m., Discovery) follows American soldiers patrolling dangerous areas of Afghanistan, featuring real combat footage captured by helmet cameras and other handheld devices.
- With students back in school, "Frontline" (10 p.m., PBS, check local listings) devotes two segments to education.
"A Subprime Education" examines growing concern about the multi-billion-dollar private college industry.
While institutions sell themselves as incubators of innovative education and escalators to success, in too many cases, for-profit schools have merely collected tuition and left students saddled with crippling debt without providing a useful degree.
And much of the funding for these so-called universities comes from government-backed loans.
Some have compared their fraudulent and predatory practices to that of shady banks during the subprime lending bubble that contributed to the crash of 2008.
"Schools" have resorted to aggressive recruiting, enrolling homeless people and drug addicts, just to keep the "tuition" flowing.
A second segment, "The Education of Omarina" follows up on a 2012 report on efforts to reduce the high school dropout rate and tells the story of a single student, Omarina Cabrera, and her path from a troubled Bronx middle school to college.
- Debuting tonight, the eight-part series "The Contenders: 16 for 16" (8 p.m., PBS, check local listings) reviews 50 years of presidential politics and recalls distinctive campaigns, some well known and others all but forgotten.
Tonight's "contenders" include Brooklyn Rep. Shirley Chisholm, who ran in 1972, when the thought of a black person or woman becoming a major party's nominee seemed beyond fantasy.
Another segment explores Arizona Sen. John McCain's first failed effort, his 2000 "Straight Talk" express campaign that appeared to charm the press corps before running into the buzz saw of power politics.
Next week, "Contenders" examines the against-the-grain races of Howard Dean (2004) and Pat Buchanan (1992 and '96).
TV-themed DVDs available today include "Suspects, Series 3 and 4."
