| - | ## Daily maintenance (ver. 19/11/04) | ||
| - | |||
| - | ## Check all fish and remove dead fish | ||
| - | |||
| - | Just check the tanks. | ||
| - | |||
| - | ## Feed fish | ||
| - | |||
| - | - For the morning part, feed powder food to them. | ||
| - | |||
| - | - For the afternoon part, feed Artemia. Use the bottle prepared 2 days ago (see the daily check sheet in the biotron). | ||
| - | |||
| - | #### How to collect live Artemia efficiently? | ||
| - | |||
| - | 1. Shake and mix the stock bottle prepared at least 2 days ago. | ||
| - | |||
| - | 1. Filter huge particles including live/dead Artemia, hatched egg shells and unhatched eggs using fine mesh. | ||
| - | |||
| - | 1. Wash filtered particles with breeding-quality water (Cl-) to wash salt out. | ||
| - | |||
| - | 1. Collect washed particle in the 50mL tube and incubate for some minutes. | ||
| - | |||
| - | 1. Since unhatched eggs quickly sink and hatched egg shells don't sink, incubated tube will show 3 layers; brown unhatched eggs on the bottom, moving live Arteimia above the unhatched egg layer and hatched egg shells on the top of the tube. | ||
| - | |||
| - | 1. Collect live Artemia with plastic pipette carefully and check if live Artemia is successfully collected. Then feed it to fish. | ||
| - | |||
| - | ## Prepare Artemia stock (For the afternoon part) | ||
| - | |||
| - | 1. Wash the bottle (you prepare stock for the bottle which you used at the day) | ||
| - | |||
| - | 1. Put a half cup of dried Artemia, 3 cups of salt and 500mL breeding-quality water. | ||
| - | |||
| - | 1. Mix and put an air stone into the bottle. **Check the bubbling! Without enough air supply, they don't hatch and all die.** | ||
| - | |||
| - | |||
| - | ## Cleaning | ||
| - | |||
| - | Clean the water outlet of each tank with a brush. Without this process, tanks become full and fish can come out from the top of the tank. **This causes a possibility of fish strain contamination!** | ||
| - | |||
| - | ## Washing filter | ||
| - | |||
| - | Wash the mesh filter on the inlet of big tank under the shelf. If they are too dirty, change with new one (cut the stock filter for the appropriate size). | ||
| - | |||
| - | ## Make sure the water tap(above the lower tank) is closed | ||
| - | |||
| - | Water in the lower big tank immediately evaporate, so make it always full. In this case, you can use the water tap above the tank but **make sure it is closed after use.** | ||
| - | |||
| - | ## Fill the count list | ||
| - | |||
| - | Count the number of fish in the specific tank (noted on the daily checksheet) | ||
