We started discussion with Nandini from Nellore, as she is working on zebrafish
Nandini uses Artemia to feed zebrafish, here artemia grows and live in salt water. Where as Zebrafish is fresh water organism
So before feeding we have to take the artemia cyst and add 1lit. tap water and a spoon of salt in it
After 24hrs larve of artemia would be seen so we can wash and feed it to zebrafish
But rather than doing this, can’t we use other fresh water organism like moina Or daphnia?
What would zebrafish will be eating in natural fresh water body like river?
How do we get moina in Nellore?
Then sakshi explained how she cultures moina by using 250ml plastic bottles
With 200ml of DC water and 1 drop of milk everyday with help of dropper
When we add milk, bacteria in the water feed on the milk and multiple, then moina feeds on those bacteria
Where if we take 5 moina today then after 3 days we will get 15 moina in the bottle
What would happen if we add more milk in the culture?
As amount if milk increase⬆, Bacteria will also increase⬆ and as Bacteria uses more oxygen, amount of oxygen in watter will decrease⬇️
So here Biological Oxygen Demand (BOD) is more as oxygen is less so to get as much as oxygen it can, moina will produce more hemoglobin
Therefore moina will turn red in presence of hemoglobin due to more milk, bacteria and less oxygen
So here CUBist study about Epigenetics to know if this red color of moina will pass on from mother to offspring
So is it possible?

For example, having a mutation in the BRCA1 gene that prevents it from working properly makes you more likely to get breast and other cancers.
