Trophic Strategy

provided by Fishbase
Inhabits rocky reefs and coral reefs (Refs. 9137, 9710, 58534, 58652, 127989); silty reefs or wrecks in lagoons, bays, or harbors (Ref. 27370), may occur in aggregations; also found hidden in caves and cracks of rocks during the day (Refs. 12382, 48635, 127989). Usually in areas subject to strong currents (Ref. 48635). Intertidal observations were also reported (Ref. 49162). Feeds mainly on benthic crabs and shrimps (Ref. 2334), also preys on small fishes (Ref. 12382). Spine of preopercle venomous (Ref. 2334). Nocturnal. Feeds mainly on decapods in addition to polychaetes, isopods, mollusks and fish (Ref. 127989).

利用

provided by The Fish Database of Taiwan
一般以一支釣及延繩釣的方法捕獲。魚肉白,但質地較爛,煮湯時肉易散開且多溶解油質,因此適合抹鹽油煎食用。唯須注意其內臟可能累積熱帶海魚毒。而它的鱗片及棘刺尖利,需小心刺傷。在水族館中也有人看上它鮮紅的體色,將它飼養做為觀賞魚。

Sargocentron rubrum

provided by wikipedia EN

Sargocentron rubrum, also known as redcoat, is a member of the family Holocentridae of the order Beryciformes. Squirrelfish in general are large, active, nocturnal fish which are usually red in color.[2]

It is found in the wide Indo-Pacific, from the Red Sea to the West Pacific, where it ranges from southern Japan to New Caledonia, New South Wales (Australia) and recently Tonga.[3] Observed since the mid-20th century in Levantine waters of the Mediterranean Sea, following entry via the Suez Canal, it is now very common through the entire eastern Basin.[4]
