Vomer small, without posterior process; periphery of glossohyal bone with single row of blunt teeth, a few teeth located irregularly at center of distal region; base of adipose fin less than 20% of head length; eye small; adipose eyelid well developed (Ref. 33312). Distinguished by its midlateral scale count of 66 to 73 and the presence of 4 to 7 pyloric caeca (Ref. 27547). Lateral line short and incomplete, reaching about to tip of pectorals (Ref. 27547). Adipose sickle-shaped; pectorals small; pelvic fins originating behind or below dorsal origin (Ref. 6885). Light olive green to brownish on back, sides and belly silvery and iridescent with a bright reflecting band along the side in living specimens; males show more golden hues than females during spawning season (Ref. 6885). Branchiostegal rays: 7-8 (Ref. 35792).

Life Cycle

Schools approach the beach to spawn, usually with the females appearing a few days before the males. At spawning, large numbers of males mill about near the edge of the surf. When a female is seen, numbers of males pursue her and try to get into spawning position. If she swims to deeper water, the males desert her. 1 to 5 males swim parallel to and slightly behind a ripe female. The males press against the female and as they reach water 2.5 to 5 cm deep, the fish bend and vibrate, releasing eggs and sperm, then retreat to deeper water. The spawning act may be repeated on several successive waves. Wave action buries the eggs, usually to a depth of 2.5 to10 cm but sometimes to as deep as 30 cm (Ref. 27547).

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). Feeds on fish, benthic animals and zooplankton (Ref. 6885).

Oviparous, with demersal eggs and planktonic larvae (Ref. 35792). Eggs are laid on beaches with heavy surf action (Ref. 33312).

Hypomesus pretiosus
(
İngilizce

wikipedia EN tarafından sağlandı
Hypomesus pretiosus, or surf smelt, is a marine smelt with a range from Prince William Sound, Alaska to Long Beach, California, although its population declines south of San Francisco. The surf smelt grows to be about 10 inches in southern waters, and 83⁄4 inches in northern waters near Canada. On average, surf smelt weigh about 10 to the pound.[1]
Spawning occurs in the nighttime, which is why it is sometimes called the night smelt,[2] peaking in the months from May to October. With a maximum age of three to four years, some females will spawn at the age of one, and all will spawn at the age of two. Females lay from 1,500-30,000 sticky eggs in the surf zone per spawn, which they may do three to five or more times in a season.[1]
H. pretiosus feed on polychaete worms, larval fish and jellyfish, but they primarily feed on small crustaceans. They can be important parts of salmon and halibut diets, and are the most economically important fish among California smelts. Around 225,000 kilograms are harvested there every year.[1][3]

wikipedia NL tarafından sağlandı
Vissen De Amerikaanse spiering (Hypomesus pretiosus) is een straalvinnige vis uit de familie van de spieringen (Osmeridae), orde van spieringen (Osmeriformes). De vis kan een lengte bereiken van 30 centimeter. De hoogst geregistreerde leeftijd is 3 jaar.
Leefomgeving
De soort komt in zeewater en brak water voor in gematigde wateren in de Grote Oceaan.
Relatie tot de mens
Hypomesus pretiosus is voor de visserij van aanzienlijk commercieel belang. In de hengelsport wordt er weinig op de vis gejaagd.

二名法 Hypomesus pretiosus(Girard, 1854) 阿拉斯加公魚（學名：Hypomesus pretiosus，英语：surf smelt）是胡瓜鱼科公鱼属的海生鱼类，分佈于威廉王子灣到長灘的地區內，不過數量在舊金山以南就開始衰减了。南方的海公魚長度達10英寸（250毫米），而加拿大附近約只有8英寸（200毫米）。[1]
阿拉斯加公魚在五月至十月的日間產卵，因此也被稱作day smelt。[2] 可存活四至五年，大部份雌魚都在二歲時產卵，但也有一歲產卵的雌魚，一條雌魚會在碎波區產卵，一次產卵約有1,500-30,000個，一般一個繁殖季節可能產三到五次，也可能更多。[1]
其食物包括多毛綱生物、一些仔魚和水母，但主要以甲殼綱動物為食。本身則是鮭魚和大比目魚的重要食物，是加利福尼亞重要的經濟魚類。年漁獲量達225,000公斤（496,000英磅）。[1][3]
