Groton Update

Here's a quick update on our trout. Here are 2 pictures at 6 weeks of development. All yolk sacs have pretty much been absorbed into the fish and most are now actively feeding on fish food from the top. The above picture is of our lone deformity. We had 5 fish die since the beginning but this one had a mutation where (from what we can decipher) the yolk sac was enclosed within the fishes belly. This skin did not recede as the yolk sac did, leaving this bubble. The bottom represents a typical healthy Brown Trout. Anyone else experience any developmental deformities?
