A Preliminary Note on the Breeding And Growth of Tilapia in Marine Fish Ponds On Zanzibar Island

Abstract

The following notes describe an initial experiment in the stocking of marine fish ponds operated by the Organization with a species of wild Tilapia found in the estuarine reaches of the Mzinga Mzinga stream, at the north-western end of Zanzibar Island. This species had been collected twice previously from Zanzibar. It is closely allied to Tilapia mossambica (Peters) and to Tilapia pangani Lowe, being fairly similar to the latter but differing from it in the lateral line scale count. It is possibly a distinct species, and Dr. Trewavas of the British Museum is working on its systematic position.
