Benefits

provided by FAO species catalogs
The most important commercially caught trichiurid or gempylid with an annual catch of 752 711 t in 1990. About 85% of the catches reported are taken from FAO Fishing Area 61, and around 60% of the total yield is taken by China. Other areas from which are reported catches of Trichiurus lepturus are 34, 57, 71, 51, 31, 41 and 47. Caught mainly with bag nets in estuaries, with trolling, beach seines, boat seines, set nets and bottom or midwater longlines in inshore waters, and with bottom trawls in offshore waters throughout the world. The total catch reported for this species to FAO for 1999 was 1 418 944 t. The countries with the largest catches were China (1 222 454 t) and Korea, Republic of (64 445 t). Excellent taste when fried or grilled, also used for sashimi (sliced raw meat prepared with soysauce and horse raddish).

Diagnostic Description

provided by FAO species catalogs
Anterior margin of pectoral-fin spine not serrated. Anal-fin origin situated below 39th to 41st dorsal-fin soft ray. Fangs in both jaws with barbs. Body extremely elongate and strongly compressed, ribbon-like, tapering to a point (tip often broken); position of anus nearer snout than posterior tip of body (preanal length about 2/5 of standard length). Mouth large, with a dermal process at tip of each jaw; lower hind margin of gill cover, concave; eye large, its diameter 5 to 7 times in head length; 2 or 3 pairs of enlarged fangs with barbs nearer tip of upper jaw and another pair near tip of lower jaw; a single series of sharp, compressed lateral teeth (often also fang-like in larger specimens) in both jaws; minute teeth on palatines. Dorsal fin rather high and long, without a notch between the spinous and soft parts, with III spines and 130 to 135 soft rays; anal fin reduced to about 100 to 105 minute spinules, usually embedded in the skin or slightly breaking through, its origin situated below 39th to 41st dorsal-fin soft ray; pectoral fins medium-sized, about as long as snout, with I spine and 11 to 13 soft rays; pelvic and caudal fins absent. Lateral line beginning at upper margin of gill cover, running oblique to behind tip of pectoral fins, then straight close to ventral contour. Scales absent on body. Excess ossification of supraoccipital, interhaemal and interneural bones often seen in specimens from Indian waters. Colour: Fresh specimens steel blue with silvery reflection, pectoral fins semi-transparent, other fins sometimes tinged with pale yellow; the colour becomes uniform silvery grey sometime after death.

Brief Summary

provided by FAO species catalogs
Benthopelagic,continental shelf to 350 m depth (from 55 to 385 m in the eastern Pacific), occasionally in shallow waters and at surface at night.Young and immature fish feed mostly on euphausiids, small pelagic planktonic crustaceans, such as Paracalanus, Acartia, Oncaea etc., and small fishes (anchovies, bregmacerotids etc.). Adults become more piscivorous and feed on anchovies, sardines, myctophiids, bregmacerotids, carangoids, sphyraenids, atherinids, sciaenids, Scomber, Trichiurus etc. and occasionally on squid and crustaceans . Adults and juveniles have opposing complementary vertical diurnal feeding migration. Juveniles and small adults form schools about 100 m above the bottom during daytime and form loose feeding aggregations at night-time near the surface where they prey on planktonic organisms. Large adults feed on pelagic prey near the surface during daytime and migrate to the bottom at night. In the Sea of Japan, this species matures at 2 years old at a size of about 30 cm preanal length in females and 28 cm in males. Some individuals of both sexes also mature at age 1 (Shiokawa, 1988). Egg production at 45 cm preanal length is estimated at about 130 000 over the entire spawning season around the central part of the Sea of Japan. Eggs are pelagic, have a diameter of 1.59 to 1.88 mm, and hatch after 3 to 6 days at a size of 5.5 to 6.5 mm total length. The spawning season is from April to August with a peak in June in the East China Sea, from July to October with a peak of September in Suruga Bay, from April to October with a peak in June in the Kii Channel, from May to November off the Kii Peninsula, and from June to October with a peak in July and August in the central part of the Sea of Japan (Shiokawa, 1988). Shiokawa (1988) estimated the age at preanal length of this species in the Sea of Japan based on otolith readings. Females: 1 year at 24 cm, 2 years at 30 cm, 3 years at 34 cm, 4 years at 37 cm, 5 years at 40 cm, 6 years at 41 cm. Males: 1 year at 23 cm, 2 year at 28 cm, 3 year at 31 cm, 4 year at 33 cm, 5 year at 34 cm, 6 year at 35 cm. For the Californian population Fitch and Gotshall (1972) estimated the age of a 83 cm total length male as 4 years and the age of a 112 cm total length female as 7 years. Migration of this species is considered to be carried out between the wintering grounds in the East China Sea and the spawning grounds in the Yellow Sea (Misu,1961). In the Sea of Japan, the wintering grounds is situated in the coastal waters, mostly on the continental shelf (Shiokawa,1988).

Trophic Strategy

Generally over muddy bottoms of shallow coastal waters (Ref. 9351). Often enter estuaries (Ref. 9351). Adults and juveniles have opposing complementary vertical diurnal feeding migration. Juveniles and small adults form schools about 100 m above the bottom during daytime and form loose feeding aggregations at night-time near the surface where they prey on planktonic organisms such as euphausiids, small pelagic planktonic crustaceans and small fishes (anchovies, bregmacerotids, etc.). Large adults feed on pelagic prey (anchovies, sardines, myctophiids, bregmacerotids, carangoids, sphyraenids, atherinids, sciaenids, Scomber, Trichiurus, squid and crustaceans, etc.) near the surface during daytime and migrate to the bottom at night. One of the main predators during summer in a sandy beach at Canto Grande, Santa Catarina, Brazil (Ref. 55758).

Migration

provided by Fishbase
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).

Max weight of 1.5 kg given in Ref. 28023 seems too low. The current angling world record was caught in Rio de Janeiro's Guanabara Bay and weighed 3.69 kg. Commercial fisherman have caught fish of up to 5 kg (Capt. Eduardo Baumeier, pers. Comm., 2001). Marketed salted or dried and also frozen (Ref. 9351). Excellent taste when fried or grilled; also for sashimi when fresh.

體甚延長,側扁,呈帶狀;尾略長,向後漸變細,末端成細長鞭狀,尾柄與肛前長的比例達40%左右。頭窄長,頭背面斜直或略突起,前端尖銳,吻尖長;左右額骨分開。眼中大;虹彩白色。口大,平直;下頜長於上頜;齒發達銳利,側扁而尖,排列稀疏,上頜前端具倒鉤狀大犬齒2對;下頜倒鉤狀多於尖形齒。鱗退化;側線在胸鰭上方顯著向下彎,而後沿腹緣至尾端。背鰭起始於後頭部延伸至尾端,具III棘,共130-141軟條,肛門前背鰭數38-42;臀鰭完全退化,起始於背鰭第43-45軟條之下方,棘狀化,但通常埋於皮下;胸鰭短,末端可達側線上方;無尾鰭與腹鰭。體銀白色;背鰭及胸鰭淡白而呈透明狀,具不顯著之黑緣;尾端呈黑色。以前文獻記載尚有沙帶魚(/Lepturacanthus savala/)產於台灣灘,惜一直未有採獲標本,其與白帶魚之差異在於臀鰭第I棘發達,超過眼徑之半。另有一種短帶魚(/Trichiurus brevis/)目前僅發現於中國大陸沿海及金門等海域,是否有分布於台灣海峽東側仍需再調查,其與白帶魚之差異在於肛門前背鰭數為34-35。

Occurs on continental shelf, occasionally in shallow waters and at surface at night. Generally found on muddy bottoms of shallow coastal waters and may often penetrate estuaries (Ref.9351). Immature fish feed mostly on euphausiids, small pelagic planktonic crustaceans, small fishes while adults feed on anchovies, sardines, myctophiids etc. and occasionally on squids and crustaceans. Adults and juveniles have opposing complementary vertical diurnal feeding migration. Large adults usually feed on pelagic prey near the surface during the daytime and migrate to the bottom at night. Juveniles and small adults form schools 100 m above the bottom during the daytime and form loose feeding aggregations at night-time near the surface where they prey on planktonic organisms. Caught in estuaries and offshore waters throughout the world (Ref. 9688). Also caught with encircling nets (Ref. 9351). Marketed salted/dried and also frozen (Ref. 9351).
