Awaous ocellaris (Broussonet 1782)

A black ocellus on the posterior part of the first dorsal fin. Upper jaw thick and slightly extended. The cheek and upper portion of operculum scaled.

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 7; Dorsal soft rays (total): 10; Analspines: 1; Analsoft rays: 10; Vertebrae: 26

Found on fine gravel bottoms from estuaries to fresh water of rivers.

fisheries: minor commercial; price category: very high; price reliability: very questionable: based on ex-vessel price for species in this family

分布於亞洲：由印度到菲律賓，北至臺灣、日本。 大洋洲海域：斐濟、法屬玻里尼西亞、新加勒多尼亞與萬那度。臺灣分布於東南部及南部河口域。

小型魚類，不具漁業價值。

體延長，前部分呈圓筒形，後部側扁。背緣與腹緣呈淺弧形。尾柄高約體高的1/2倍。頭長為體長的1/3倍。眼居上側位，眼間距內凹，寬度小於眼徑。吻鈍，吻長約等於眼徑。口前位，上頜、下頜約等長，口裂延伸至眼前緣的下方。胸鰭圓扇形，胸鰭上部分有游離的鰭條。腹鰭呈吸盤狀。臀鰭與第2背鰭同形，臀鰭基底較第2背鰭基底長。尾鰭呈圓形。頭、體呈淺棕色，體側中部有7~8個灰黑色不規則斑塊，最後面的斑塊在尾鰭基部中央較大；體背側具許多深褐色的細斑；眼前下方至上頜有2條黑褐色斑紋，成魚較細，或不顯著；頰部另散布細點或短紋。第一背鰭有灰黑色斑塊，鰭棘後部上有1個黑色眼斑；第二背鰭及尾鰭各具黑褐色點狀斑紋。(林上智、林沛立編寫 2012/10)

暖水性底層小型魚類，棲息於淡水河川中，上溯河川的能力頗強，經常能夠在河川中游處發現其蹤跡。其以水生昆蟲為食，也啃食藻類。數量豐富。因其體型較大，體色特殊，容易飼養，可當作觀賞魚進行養殖。

Awaous ocellaris is a species of goby native to fresh, marine and brackish waters of southern Asia from India to the Philippines, and eastern Asia to Japan as well as the islands of Oceania. This species can reach a length of 13 centimetres (5.1 in) TL. It is of minor importance to local commercial fisheries.
