Short description
เครื่องมือที่ใช้ในการแยกชนิดสัตว์,สิ่งมีชีวิตออกจากกัน | สัณฐานวิทยา | ความยาวต่างๆ
เงี่ยงครีบหลัง (รวม) : 0; ก้านครีบอ่อนที่หาง (รวม) : 15 - 16; เงี่ยงครีบก้น: 0; ก้านครีบอ่อนที่ก้น: 16 - 17; สัตว์มีกระดูกสันหลัง: 44. Diagnosis: Body slender, its depth about 17-22% of standard length; 13-14 pre-pelvic and 8-9 post-pelvic scutes, with pre-pelvic scutes not strongly keeled, beginning behind base of last pectoral finray, but post-pelvic scutes with sharp spines; maxilla blade about 2.25 times as long as its shaft, but not continued forward to hind tip of pre-maxilla; posterior supra-maxilla diamond-shaped or more or less rhomboidal, approximately symmetrical; lower gillrakers long and slender, 36-42; a distinct silver stripe along flanks, broadest over tips of pelvic fins (Ref. 188, 93833). It resembles Limnothrissa miodon of Lake Tanganyika, which is slightly deeper-bodied, has a larger eye, about equal to head length behind eye, and a maxilla blade continued forward to hind tip of pre-maxilla (Ref. 188).
A pelagic, lacustrine species, forming very large schools (Ref. 188, 36901, 121343). The juveniles tend to stay closer to the shore than those of 5 cm standard length or more (Ref. 188). They appear to spend daylight hours at a depth of 70-95 m, rising up to 8-15 m at night, especially on dark nights (Ref. 188, 36901). These migrations reflect also the plankton migration (Ref. 36901). It feeds on plankton (Ref. 36901, 93960, 121343, 121352), like prawns, shrimps, also copepods, chironomids, diatoms and algae (Ref. 188). It breeds at about 6 cm standard length, with ripe individuals present almost throughout the year, but major spawning in May-June and again in December-January, the adults moving inshore to breed; the eggs sink slowly (Ref. 188). It is caught with seine nets, often using lights (Ref. 188).
