My contacts at QM say they have a consistent source producing around 10-20/month which from what I know about shark breeding that's a ton of eggs! They told me that as long as demand continues, they will continue to provide them. They also said they are all over a month old and feeding well on Krill and PE mysis.
Can you find out how many they sell a month? Not only the white spotted but other sharks to. I am kind of curious.
