The pink maomao (Caprodon longimanus), also known as the longfin perch, is a species of marine
ray-finned fish, a member of the subfamily Anthiinae which is part of the grouper and sea bass family Serranidae
. It is found in the southern Pacific and the southeastern Indian Ocean.
Description
The pink maomao has long and pointed
anal fin has 3 spines and 7-9 soft rays. In specimens from the eastern specific there are 58-65 scales in the lateral line while in specimens from the western Pacific there are 61-71 lateral line scales.[2] The females are an overall mauvish pink colour while the males are a similar colour but may show blackish blotches on the back and upper flanks and on the dorsal fin and males also have yellowish dorsal, caudal, anal and pelvic fins.[3] The maximum recorded fork length is 55 centimetres (22 in)[2] but they are more commonly recorded at fork lengths pf 28–30 centimetres (11–12 in) and they normally weigh around 1 kilogram (2.2 lb) but can reach 2 kilograms (4.4 lb).[5]
Distribution
The pink maomao is found in the southeastern Indian Ocean off
D'Urville Island and Kaikōura in New Zealand, especially in the north island.[3] They also occur in the southeastern Pacific around Easter Island, the Juan Fernández Islands, the Nazca Ridge and the Isla Salas y Gómez. It has also been reported from the Hawaiian Islands.[1]
Habitat and biology
The pink maomao is found near inshore reefs and its habits are both
protogynous hermaphrodite, they are hatched as females and may change sex to become male.[4] Juvenile fish are only occasionally observed suggesting that this species breeds infrequently in low numbers.[5]
Taxonomy
The pink maomao was first formally
type locality not being stated but thought to be Australia.[7] Studies in New Zealand suggest that there are two species occurring there, one from the Kermadec Islands and the other from the North Island and the west Norfolk Ridge.[3]
Fisheries
The pink maomao has thick, white flesh which is excellent eating and it is pursued by spearfishermen[5] but is infrequently caught by line fishermen.[8] Bag limits are in place in New Zealand.[5]
