This may have occurred when being moved onto the boat when caught, or when being corralled into the sling in the holding tank.
Todd Glodek and Kevin Polk, both from The Rosensteil School of Marine and Atmospheric Science (RSMAS), went fishing for broodstock this morning. Catching one Yellowfin tuna on their boat, and collecting another Yellowfin tuna from a nearby fishing boat that had just reeled it in. Both these tuna were kept alive and transferred into the holding tank at Achotines.
This afternoon several people in the course, led by Dr Gavin Partridge, set up a small scale trial on a clear larval tank. The plan is to try several different ideas with the tank to asses mortality and survival rates.
The feeding regime today was a 0100 feed of rotifers and algae as well as an 0800, 1300 and 2000 feed on the trial tanks.
Spawning today happened as usual just after 22:30, with two collections for a total of over 500,000 eggs.
