First Night Sees 90 Per Cent Fertilisation

ACHOTINES BAY, PANAMA - On day one of the 7th Annual Workshop delegates arrived at the facility and met Vernon Scholey, the Laboratory Director at the Inter-American Tropical Tuna Commission, reports Alex Mhlhlzl.

In the morning the attendees heard a spawning and witnessed the collection of eggs. As normal light conditions cause a 'spooking' effect in tuna - a condition which causes the fish to rapidly accelerate, endangering themselves to critical collisions against tank walls - a red light was used to keep distress to a minimum.

The eggs were collected by a surface filter scoop and deposited into another fine mesh filter storage system. Once this stage was complete the eggs were counted via a density method, before being distributed among the incubators.

First nights collection was over 600,000 eggs with an almost 90 per cent fertilisation rate.
