Humanoids from the deep (1996)

In this remake to the original 1980 ecological horror movie, a secret government experiment turns nightmarish when genetically altered fish, bred as amphibious weapons, escape. Scientists believe them dead after a biohazardous chemical spill. Far from it, the creatures thrive as bloodthirtsy killers, threatening to annihilate a small coastal town by slaughtering the men and abducting the women for mating! Government scientists attempt to keep the creatures' origin a secret while trying to destroy them.
