Abstract: Post-larval organisms are introduced and held for growth to marketable size in a controlled environmental unit which has a dome over a body of water. The configuration of the unit and the techniques of establishing a self-sustaining eco-system within the unit and heating the body of water by bubbling heated air therethrough allows for maintaining the living conditions of the organism in a location geographically remote from its natural habitat.

Abstract: A disposable mouth-to-mouth resuscitation device which avoids mouth-to-mouth contact of a rescuer with the victim being resuscitated, and which prevents exhaled vomit from the victim from coming into contact with the rescuer. The device includes a body having a mouthpiece into which the rescuer breathes. The mouthpiece includes a mask that covers the mouth of the victim during resuscitation. A tongue depressor tube insertable into a victim's mouth is releasably attached to the body. A flapper valve disposed in the body permits the victim to exhale breath and vomit from coming into contact with the mouth of the rescuer. The victim's breath exits through an escape port that bypasses the flapper valve.
