Oceanic Institute of Hawaii Pacific University is making some great headway with rearing Yellow Tangs! Check out the videos of the 36dph and 49dph groups at the Rising Tide Facebook Page: https://www.facebook.com/Rising-Tide-Conservation-850675348332972/
“The [Yellow Tang] group that is 70dph only has a handful remaining, and just a couple of that handful look like the photo. We are observing a pretty significant gap in development within cohorts, where some fish are extremely stunted compared to their siblings. However, we are really excited to be seeing the dorsal and anal fins forming, which is signaling that the transition to settlement is close! The next group that we have is 49 dph today and many of these fish appear similar in development to our day 70 group. This tank has more than 100 remaining, and they appear really strong, much more lively and active than the day 70 group did at the same age. We are really excited about these 49 dph fish, as they really seem to be doing well. They are even eating frozen cylcopeeze! Finally, we have another group at 36dph and there are over 1,000 in that tank. They have started taking artemia and dry feed and we are really optimistic that they will continue to thrive as well!!
The biggest changes since our first “success” last year are that we are overlapping the live feeds much longer. The fish are getting broader combinations of copepods, rotifers and artemia, where as last time we relied almost exclusively on copepods (of varying sizes). We also offered dry feed more intensively and at earlier stages, which I think is really helping.”
