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.

生物学特性     字汇 (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 网捕捉了, chirimilas 或者海滩围网 (伦巴拉网) 有淡色的。 (参考文献 4967) 生活在砂质底部之上早晨时而且稍后向外海移动一些在白天期间。 (参考文献 5595) 形成鱼群。 (参考文献 4365)
