UH OH! The internet is down today Katie fed fish breakfast with tetramin I fed fish lunch with tetramin Fry in incubator still alive. woohoo! Incubator setting 3: 28 C Continued cleaning the tanks ---> Tank 2 and 3 --->bleached gravel in Tank 2 Made salt water --->gallon water from reverse osmosis --->cup of salt Set up new brine shrimp hatchery Dr. Hyde e-mail? still no word... TOMORROW: continue the cleaning //**Observations**//: This is the longest that we've been able to keep our fry alive. They are now 6 days old and only 1 has died. I believe the incubator is the reason that they are still alive because that is all that has changed since our last breeding. It could be that the temperatures in the lab vary too much overnight seeing as we only have on small radiator by the window and also because there are windows on two of the walls (lots of cold air). All the other tanks have heaters and thermometers to keep track of the temperature of the water but there is no way to heat the water in the fry containers. So the warm temperature is most likely the reason for the increased survival rate. Yay!

Katie fed fish breakfast with brine shrimp I fed fish lunch with brine shrimp (yummy!) Fed fry in incubator ---> fry have moved from Powder 0 to Powder 0+1 ---> * in about a month, if fry still alive, they can be moved to a tank with a thermometer and stable temperature
 * brine shrimp aquarium not totally hatched but still usable
 * --->* changed water in fry container; it was starting to get clogged with food
 * its VERY important to clean the fry containers because the food can coat the top of the water forming a layer and stop the fry from getting oxygen. not good.

Continued cleaning tanks ---> Tank 2: washed and rinsed; no more bleach smell (*VERY IMPORTANT!) --->Tank 3: washed and rinsed; no more bleach smell Made more salt water (1 gallon water, 1 cup salt)
 * Set up breeding tank with two male albinos from Tank#4 and two female albinos from tank #5...cross your fingers!**

Katie fed fish breakfast with brine shrimp I fed fish lunch with brine shrimp (aquarium appears to be all hatched!) Fed fish 10th period as usual with brine shrimp Breeding: --->no eggs --->females still appear to be "full" (usually after breeding their bellies are considerably smaller) Fed fry wth powder 0+1 Returned gravel to #2 (gravel doesn't smell like bleach) Filled tank #2 about 1/3 of the way with water ---> we would have filled it up all the way but we emptied out the reservoir of the reverse osmosis sytem (...it only collects so much a day)
 * returned fish to original tanks (famales to tank #5, males to tank #4)
 * Finished outline for milestone map

//**Observations**//: Finals are gunna stink :(

No here. On field trip to sing Christmas carols. See KMH's Week 2.

Katie fed fish breakfast I fed fish lunch Fed fish 10th period Fed fry in incubator/ half of fry are dead... Added more water to tank #2; almost full

//**Observations**//: Over these past months, we've been able to "master" our brine shrimp hatching skills. Over the summer the process was slightly differerent; there was the same set up but we emptied the hatchery every day and concentrated the shrimp into a smaller container with less water. But we realized as we've been continuing the process this year, that we end up wasting a very large amount of eggs. Only about half of the brine shrimp eggs hatched overnight and so we ended up sending them down the drain when we collected only the hatched shrimp. Since we had learned the brine shrimp can stay alive for about three in the temporary aquarium we made with a soda bottle and salt water, we decided to let them "brew" in there for a day or two longer before emptying the aquarium. It worked! We found that almost all the shrimp eggs hatched and our daily collections were much more heavily concentrated with shrimp. Our daily collections are definitely helped by the lamp we use; the shrimp swim toward the light and heat so it is easier to collect them. When the air tube is removed and the lamp is set in place, the empty shells sink to the bottom and the shrimp swim to to the side making the collection VERY easy.
