Sources close to production tell TMZ ... Sig and the crew of the F/V Northwestern were at sea, with cameras rolling, when the captain briefly passed out. We're told Sig brushed it off when he came to, and wanted to keep fishing.

The production crew insisted he get medical attention, and he was airlifted to a nearby hospital.

His daughter posted a pic of him smiling in his hospital room. The family thinks he suffered a heart attack, but doctors are still running tests.
