Highlands Trout at Katse Dam in Lesotho are undertaking the first large expansion from 500 t.p.a of production to 1250 t.p.a production of trout in floating cages. The cages have been imported from Akva in Norway. The local Lesotho team have previously been trained in assembly of these, which takes place in sections on land at the Katse workshop facility. After the sections are assembled, they are moved into the water at the slipway and bolted together to form 20m by 20m square cages. These are then towed out to the mooring site on Katse Dam and once moored, the internal nets are hung and the outer cage is covered by bird netting. Fish stocking to these cages is underway.
Due to the high primary productivity levels in Cahora Bassa, Mozambique, algal biofouling in tilapia (Oreochromis niloticus) farm cages is problematic and requires constant maintenance. A joint initiative, administered by Advance Africa, between “Copalcor” and “Mozambezi Fisheries and Aquaculture” was initiated in May 2013 and the project aims to investigate the influence of two copper net mesh sizes on the growth and performance of tilapia in comparison to standard nylon and HDPE netting.
Advance Africa have commenced with the second phase of the Seychelles Mariculture Master Plan project, which began on 9 July when funding was received from NEPAD. This phase is geared principally towards the development and finalization of the regulatory framework that will guide the development of mariculture in the Seychelles and developing an appropriate application procedure.
The current focus is on meetings with several government agencies and departments to discuss amongst others, allocation of land for developing a hatchery cluster, investment incentives, and making arrangements for two oceanographic cruises to verify the locations of offshore mariculture development zones.
The 1st draft of the Regulatory Framework and the application procedure has been submitted to the review committee. The team, comprising of Prof Tom Hecht and Myles Badenhorst of Advance Africa and Aubrey Lesperance of Seychelles Fishing Authority, also completed the 1st draft of the environmental monitoring procedure for sea-based sites, a protocol for benthic and water chemistry sample analyses, as well as a protocol for CTD side scan sonar and ROV survey of aquaculture sites.
Advance Africa are pleased to announce the appointment of Myles Badenhorst who joins our team from the 1st of November 2012. Myles has a BA Geography and BsC Honours degree in Geography from the University of Witwatersrand. He has considerable skills in the areas of environmental sciences, GIS, conservation, and has completed an Aquaculture Innovations course in Grahamstown. We look forward to having Myles in the team!”
