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.
