Frigate Mackerel (Tuna) at Long Ke Wan (Sai Kung)

had fun dive at Long Ke Wan (Sai Kung) on 3rd July.

dived with a Mexican. It was quite dangerous at the end of the first dive because a speed boat pass by our head, when we were swimming to boat at the depth 3m.
In the second dive, I saw a group of yound Frigate Mackerel (one kind of Tuna). Their size was about 10 inches and I guessed there were about 150-200 piece.
This has been the first time that I saw tuna in Hong Kong since I learned diving.
當上水後問其他船上的人是否很到這群Tuna?他們境然不相信我看到的是Tuna。還問是不是看錯章紅當Tuna?
Tuna這麼明顯的特徵都攪錯?

而章雄即(Greater amberjack)

所以經常留意魚的特徵,不難分開2者。
