Secutor ruconius (Hamilton 1822)

Description: Body silvery, dorsal with 10 narrow dark or faint vertical bars down to midlateral. Head naked, with nuchal spine; mouth protrusible pointing upward; tip of maxilla reaching to about level of lower margin of eye. Body very deep and compressed, depth max 1.4-1.7 in SL; breast fully scaled. Lateral line ending about middle of soft dorsal fin. (Ref. 2108, 90102)

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): 8; Dorsal soft rays (total): 16 - 17; Analspines: 3; Analsoft rays: 14

Between February and May, adults are less abundant in estuary. Feeds on invertebrates (Ref. 4959). Also Ref. 58652.

Found in coastal waters. Enters estuaries and rivers (Ref. 30573). Usually over sand or mud bottoms and rarely near reefs (Ref. 90102). Forms schools. Feeds on small crustaceans (Ref. 5213). Marketed fresh or dried and salted (Ref. 12693).

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