Abstract
A commercial fishing net takes advantage of animal psychology to easily permit the escape of entrapped porpoises while preventing the escape of desired tuna and other edible fish, the net having at least a portion comprising a drop net which sinks beneath the water surface to a depth defined by tethered floats when a control bladder attached to the top of the drop net is deflated, there also being an optional stiffener hose extending along the top of the drop net and being filled with a releasable pressurized fluid to maintain the upper edge of the drop net aligned and prevent the bunching of this net portion.
