| Hypomesus pretiosus (Girard, 1854) | ||||
| Family: | Osmeridae (Smelts) | ( not available ) | ||
| Order: | Osmeriformes | |||
| Class: | Teleostei | |||
| English name: | Surf smelt | |||
| Distribution: | Eastern Pacific: Prince William Sound, Gulf of Alaska to Long Beach, southern California, USA. Reports from the western Pacific are misidentifications of Hypomesus japonicus. | |||
| Adult biology: | Individuals 3.5 cm may ascend rivers, presumably returning to the sea shortly after (Ref. 27547). Presumably young move offshore and reappear inshore as mature adults (Ref. 27547). At sea, they feed on small crustaceans, worms and jellyfish, as well as larval fishes (Ref. 6885, 10276). Females reach age 3, males age 2 (Ref. 27547). Oviparous, with demersal eggs and planktonic larvae (Ref. 35792). Eggs are laid on beaches with heavy surf action (Ref. 33312). | |||
| Diagnosis: | Number and arrangement of preanal ventral midline melanophores (lacking in clupeoid larvae); absence of diagonal muscle layers that are present in clupeoids. Pigmentation: Preflexion-flexion: 8-11 on preanal ventral midline; 2-4 on postanal ventral midline; 1-4 below notochord tip; about one-third of larvae have 1-2 on postanal dorsal midline; lateral pairs between gut and trunk musculature increasing to 15-16 at end of flexion stage; lateral pair on terminal section of gut. Sequence of fin development: caudal, anal and dorsal, pectoral and pelvics.. See also LARVAE table. | |||
| Climate Zone: | temperate; 61°N - 33°N | |||
