Type of rearing unit:
|SEMI-OPEN MULTI-TANK ARCTIC REARING SYSTEM|
Memorial University – Semi Open Multi-Tank
The researcher wishes to operate the Multi-tank system under semi-open conditions as plankton carried by natural sea water is required to feed the marine invertebrates housed within the unit. This water will be introduced in the system as a constant make-up flow. Consequently, no solid filtration, biofiltration or chemical treatments will be required in this unit as these may remove the plankton. The water exchange rate (up to 200% v/v water change per day) will be adjusted to maintain rearing conditions optimal.
This system will then consist of the fish holding portion of a standard arctic system, plus the necessary equipment required to pump and chill the water. The water chilling control precision is ±0.3°C. Furthermore, the standard control & monitoring system will be included, along with the fixtures above the shelves for photoperiod control (one photoperiod for the whole unit).
The system should accommodate up 24 x 9.4 Liter tanks. In option this system can accommodate up to 64 x 1.5 Liter tanks or 48 x 2.8 Liter tanks. The current unit comes with 24 x 9.4 L tanks.
Each shelf has a row of LEDs. The Habitat Module has an opaque insulation (isolates from room lighting).
