| Species you are culturing: | |
Make-up Water Source:
We are assuming that clean source water is used, low in nutrients and without unusually high mineral concentrations. If in doubt, send a water sample to a reputable laboratory and fax us the results. |
| Where does your water come from (city, well, reservoir, etc.)?: | |
| Make-up water flow rate: | % of total volume replaced per day. |
| Temperature range: | °F to °F. |
| Maximum sustained pH (12-hour period): | |
| Note: High pH = high un-ionized ammonia (NH3) = low allowable total ammonia (TAN) = reduced nitrification = bigger biofilter. |
| Dissolved oxygen concentration of water entering the biofilter: | mg/l |
| Total system water volume treated by biofilter: | gallons |
| Nitrogen Loading: |
| Individual average body weight at harvest time: | lbs, or grams |
| Maximum number of animals served by the biofilter at time of harvest: | |
| Typical feed rate prior to harvest: | percent of body weight per day. |
| Feeding frequency prior to harvest (give times of day): | |
| Feed protein content: | percent |
| Feed type (describe): | |
Solids Filtration:
Fish waste must be filtered out prior to the biofilter. This will reduce biofilter fouling and heterotrophic bacterial activity. |
| Solids removal system (describe): | |
| Solids, size filtered: | microns |
| Biofilter Type Preferred |
| Bead (Bio-Clarifier) Fluidized Sand. | Rotating Biol. Contractor (RBC) |
| Low-Space Bioreactor (Moving Bed) | Trickle |
| Fluidized Sand. | Other |
| If you have information on one-pass total ammonia nitrogen (TAN) removal efficiency for the biofilter type you wish to use, please specify: | percent |
| Describe the water quality conditions under which this one-pass ammonia removal was achieved: | |
| Further describe your system and biofiltration requirements | |
| If possible, please provide us with the feed chart you intend to use for your species based on weight and water temperature. |
| Note: Our calculations are based on standard aquacultural engineering methods and current scientific studies. |
