situated on a site in the southwest corner. The ponds are rectangular, 1.0-1.5 m deep, each provided
with independent inflow and drainage sluices. A fish sump is dug around the edge of the production
ponds. Most bunds are accessible by vehicle.
The stocking programme in Barseek fish farm involves stocking with grass carp on first filling the
pond in October/November or December, after the post-harvest preparation. Mullet fry (mixture of M.
cephalus and M. capito ) are added in March when these become available from the coastal waters. In
May common carp are stocked. Tilapia is mostly stocked by uncontrolled inward migration from the
canals. Harvesting takes place in October to February. The small size of the mullet and carp implies a
low survival rate and presumably the ponds are stocked well below their carrying capacity towards the
end of the growing season. The management of both the capture fisheries of Lake Edku and the
Barseek Fish Farm are under the jurisdiction of the Department of Fisheries of the Governorate of
Beheira. The discharge of the Barseek fish farm into Lake Edko through Barseek drain is an obvious
water quality problem affecting the lake. Figure (5-9a) shows the fish ponds around the lake area and
figure (5-9b) shows the pumping stations of Barseek fish farm.
