Fish checklist grows further at Cape d’Aguilar

Despite
poor visibility at the Marine Reserve all summer, a number of new records
have been made in recent months. On 25 June a small school of Silvery
Moony (Monodactylus argenteus) were recorded at 10 m depth. The
same day, a 35 cm Giant grouper (Epinephelus lanceolatus) was
observed in a small cave (Fig. 1). This huge species, which can reach
2.30 m in length, has been very rare in Hong Kong in recent decades
although a few have been seen on artificial reefs in recent years (Wilson
2003). There has also been a resident school of Rivulated parrotfish
(Scarus rivulatus) consisting of four terminal males and
more then ten initial phase females. Although the females are relatively
abundant locally, this is the first time I have seen a male in >
700 dives. A 20 cm terminal male Globehead parrotfish (Scarus globiceps)
seen on 10 July with the Rivulated parrotfishes is not just a new record
for the reserve, but also for Hong Kong. The cumulative total of reef
fishes at Cape d’Aguilar (see More new fishes from the Cape d’Aguilar
Marine Reserve, Porcupine! 28) is now 184.
