WORTH NOTING ON TV

* SATURDAY

Duckman (USA Network, 10:30-11 p.m.): This often-acidic animated series quickly acquired dedicated fans - well, cult followers, to its nonfans - when the show premiered last year.

Now it's back for a new season, still featuring a politically incorrect duck detective given to acrimonious tirades against virtually any aspect of society that incurs his displeasure.

It's a show not designed for kids and not even for all adults, some of whom dislike its outspokenness. But many viewers find it exactly the change of pace they need in today's TV world. Lots of guest stars do voice-overs or the occasional live-action appearance.

In the season opener, Duckman inadvertently becomes a media personality, a success that ends as quickly as it began. * SUNDAY

CNN Presents ... The Wild, Wild East (CNN, 9-10 p.m.): ``Crime'' now tops ``official oppression'' as the main source of fear for many Russians in Moscow, where murder is up 40 percent, rape and robbery 42 percent, and fraud 170 percent.

As shown in this edition of the weekly newsmagazine, the shift is part of Russia's problem with organized crime, which is harming that country's shaky economy and affecting the person on the street.

It is also affecting Europe and the United States. Among the people interviewed is FBI Director Louis Freeh, who says, ''The threat that exists there is grave to Russia, and also very, very significant to our own safety.''
