A spar buoy pen system (10) formed of a net pen (14), vertical spar buoys (16), and anchors (18). The spar bouys (16) are formed of elongated tubular columns having a center of ballast above the center of gravity to flow in a substantially upright position. Anchor lines (22), auxiliary floats (24), and attachment lines (32) deflect the spar buoy (16) at a predetermined angle such that the spar buoys (16) and the anchors (18) cooperate to hold the net pen (14) in a predetermined configuration and in a taut condition.
