More Baby Fish Have Arrived!

February 3, 2012

On Friday, January 27th half a million eggs arrived from Miami, Florida! They were placed in an incubation tank, where they hatched early Saturday morning. To the naked eye they looked like pieces of rosemary floating in the water. But under the microscope you could see the egg sack that was encased around the head and the tail was sticking out. The bottom of the tank was siphoned in order to get rid of the unhatched eggs and dead larvae. This is very important because if they were left in the tank bacteria can grow, which can kill the larvae. After determining how many larvae were alive, they were then transferred into six larval rearing tanks. They will obtain their food from their egg sack for three days. Cobia develop after they hatch, which means their mouths are very small and in turn can only eat rotifers for the first couple of weeks. They will eat enriched rotifers for about three weeks and then move onto eating artemia for another 45 days. Once they start growing more we will be able to wean them onto dry food and then eventually bring them out to the offshore cage that is fitted with shark resistant netting that was donated by DSM Dyneema!
