Tanzania country information

Common names: Usipa
Occurrence: native
Salinity: freshwater
Abundance: | Ref:
Importance: highly commercial | Ref: Eccles, D.H., 1992
Aquaculture: | Ref:
Regulations: | Ref:
Uses: live export: yes;
Comments: Occur throughout Lake Nyasa. Appears to be truly pelagic, with larvae found in nearly all samples of plankton. A pelagic plankton-feeding species which supports a large commercial fishery that recently developed in Malawi. A major food species for Opsaridium and Rhamphochromis. Shows great variations in abundance, but high fecundity enables population to develop rapidly from low levels (Ref. 4967). Also Ref. 54530.

簡短描述 型態特徵 | 形態測量圖

Steely blue coloration on upper part and silvery blue on lower part of the body. Dorsal-fin origin above anal-fin origin.
在上半部上的鐵藍色的顏色與銀藍色在身體的較下面的部位上。 在臀鰭起源上面的背鰭起點。

生物學特性     字彙 (例如 epibenthic)

Caught using plunge nets, chirimilas or beach seines (lamparas) with light (Ref. 4967). Occurs over sandy bottoms in the morning and move a little offshore later during the day (Ref. 5595). Forms schools (Ref. 4365).

使用 plunge 網捕捉了, chirimilas 或者海灘圍網 (倫巴拉網) 有淡色的。 (參考文獻 4967) 生活在砂質底部之上早晨時而且稍後向外海移動一些在白天期間。 (參考文獻 5595) 形成魚群。 (參考文獻 4365)
