Abstract
Source of the Nile Fish farm (SON) is located at Bugungu area in Napoleon Gulf, northern Lake
Victoria. The proprietors of the farm have a collaborative arrangement with NaFIRRI to undertake quarterly environment monitoring of the cage site as is mandatory under the NEMA conditions. The monitoring surveys cover selected physical-chemical factors i.e. water column depth, water transparency, water column temperature, dissolved oxygen, pH and conductivity; nutrient status, algal and invertebrate communities (micro-invertebrates/zooplankton and macroinvertebrates/
macro-benthos) as well as fish community. The second quarter survey for the calendar year 2015, which is the subject of this report, was undertaken in June 2015.
Results/observations made are presented in this technical report along with a scientific
interpretation and discussion of the results with reference to possible impacts of the cage facilities to the water environment and aquatic biota
