“…Water that leaves the refugium enters a 45,000-L sump, where two 5-hp motors on variable frequency pump it back to the stream inlet for reuse; the pumping rate ranges from 560 to 6,250 L/min.

The naturalized conservation aquaculture unit (refugium) at Los Lunas Silvery Minnow Refugium is the first purpose‐built, large‐scale conservation aquaculture mesocosm. The refugium is 0.2 ha in area, with 0.11 ha of interconnected water habitats, including a stream with sand bars, five ponds, shelves, marshes, attached bars, and overbank areas that can be inundated to create floodplains. The key components of conservation aquaculture management in the refugium are as follows: (1) no artificial feed is used, so that the fish develop the foraging strategies that will be needed in the wild and do not develop maladaptive behaviors associated with feeding; (2) the production of natural food organisms is based on indirect fertilization; (3) fish are subjected to managed predation, so that when stocked they are not behaviorally naïve; and (4) low stocking rates are used to mimic population densities in the wild. Results from 6 years of management and the lessons learned about facility design and conservation aquaculture management are discussed.

“…The refugium and how it functions hydrologically were described by Tave et al (2011). To help create a natural mesocosm, native plant species were planted in the ponds, marshes, shelves, and along the berm that surrounds the refugium (Coleman et al, 2011). Conservation aquaculture management techniques used to culture the Rio Grande silvery minnow in the refugium were described by Hutson et al (2012).…”

“…Ponds 2 and 4 have marshes (Figs. 1 and 2) that are composed of nine species of rushes and sedges (Coleman et al, 2011); the predominant ones are: Torrey's rush Juncus torreyi, common spike rush Elocharis palustris, and softstem bulrush Schoenoplectus taberaemontani. Swim-up fry are often found at the edge of these vegetated areas.…”

A major reason why conservation aquaculture is needed to improve the success of aquaculture-assisted fisheries is that traditional production aquaculture produces fish with mal-adaptive behaviors. These behaviors can be produced via domestication and culture techniques, and preventing these mal-adaptive behaviors requires integrating improvements in genetic management and culture protocols. The genetic protocols needed to minimize hatchery-induced genetic changes have received considerable attention, but changing the way fish are raised has received less effort. Conservation aquaculture cultures fish in environments that resemble their native habitats so that when stocked, they behave like wild fish rather than hatchery fish. A purpose built-conservation aquaculture facility can also be used to learn about a species’ behavior and how it reacts to changes in the environment, something which can be difficult or expensive to study in the wild. These observations can then be used to help direct both propagation and recovery management. This paper provides the rationale for why genetic management, culture systems, and management practices need to be altered to produce fish that are behaviorally similar to wild fish for aquaculture-assisted fisheries programs. It then provides a description of some of the behaviors of the endangered Rio Grande silvery minnowHybognathus amarusthat were observed at the Los Lunas Silvery Minnow Refugium, a purpose-built conservation aquaculture facility, and explains how some of these behaviors can be used in culture and recovery management. Behaviors described are: schooling; predator avoidance; feeding behavior; use of vegetation for cover and predator avoidance; habitat use by bottom substrate; location in the water column; upstream movement via a fish ladder; movement upstream in a high-velocity channel; response to changes in water level; spawning behavior; seine avoidance; and Kaah-chee-nyee Srkaash, a behavior described for the first time.
