March 2 - An Anomaly

Post date: Mar 04, 2013 1:43:28 AM

Our developmental index is about 71% and we are on schedule for release at the end of April. Most of the alevin (sac fry) appear to be developing normally but one little guy has not been so lucky. The fish on the right shows problems with the tail, which appears to be coiled and attached to the sac. The three on the left are doing fine. The largest of the three (bottom-right in the petri dish) was the first one to hatch in January. Some of the fish are now swimming in the tank but most are clustered together in corners.
