More specifically, a nested raceway system includes a first vessel and a second vessel. In an embodiment, there may be more than two vessels. In another embodiment, the first vessel has a base with a head-end bulkhead, a tail-end bulkhead. The second vessel has a second base with a plurality of apertures thereon, a second head-end bulkhead, and a second tail-end bulkhead. The second vessel is nested (i.e., suspended) within the first vessel and creates at least two habitats within the first vessel. The plurality of apertures allows for small marine life, algae, or other valuable minerals to sink to the bottom to be removed or grown. In an embodiment, the first and second vessels are constructed of a floatable, durable, and flexible material. ## Claims ### Claim 1 An apparatus for use in water with flowable material comprising: a first vessel comprising: a first base comprising a head edge, a tail edge, a first side edge, and a second side edge;
