Experimental cage farming in Tanzania started in 2013 with a study to test the effect of different
stocking densities of Nile tilapia on growth, survival, Food Conversion Ratio, and impact on water
quality. Although the experimental results were influenced by relative high mortality during the early
phase of the experiment, the highest final biomass after 6 months was in the order of 11kg/m3.
Commercial productivity at SON farm in Uganda is in the order of 50 kg/m3 after a 7 month production
cycle, indicating the potential for higher yields. No environmental impacts (based on pH, oxygen and
other water quality parameters) in the direct vicinity of the cages was observed. The study
recommended the use of cages in the lake provided that site studies are made with regard to wave
flushing and continuous monitoring of the environmental parameters (TAFIRI 2013). The report with
recommendations will be submitted to the Ministry of Livestock Development and Fisheries and the
LVFO, for approval of commercial cage farming in the Tanzanian part of Lake Victoria. Meanwhile,
several parties have expressed an interest to develop a cage farm in Lake Victoria. Among them is
VicFish, a Nile perch processing company in Mwanza. VicFish factories are presently operating at only
50% capacity (25 MT/day) due to declining Nile Perch catches, severely affecting the profitability of
the company. VicFish is developing two aquaculture projects, one on land and a cage farm. Both
projects are awaiting governmental approval.
With a coastline of over 1400 km (including the islands of Zanzibar, Pemba and Mafia), suitable water
and temperatures, there is considerable potential for coastal aquaculture development in Tanzania.
Despite past initiatives and research projects, at present only one commercial shrimp farm is
operational (Alphakrus Ltd.). General concerns about environmental degradation, disease problems in
shrimp farming, and lack of inputs and technology, have hampered coastal aquaculture development
so far
3.5.2 Availability of inputs (for tilapia culture)
Reasonable numbers of Nile tilapia fingerlings (both mixed and monosex) are available through
various small (semi-) commercial hatcheries and governmental stations (see Annex 4).
Although not much is known about the quality and productive performance (none of the hatcheries are
using breeding programmes for genetic improvement), at the present stage of tilapia aquaculture in
the country the availability of fingerlings is not immediately constraining further development.
Raw materials of plant origin for incorporation into tilapia feed, such as rice bran, wheat middling’s,
maize, maize bran, cassava, cotton seed cake and soybean meal are readily available but may be in
competition with use for livestock feeding. There are presently no factories that produce formulated
fish feeds in Tanzania. Farmers either use farm made feeds (meals or simple (extruded) pellets), or
purchase simple feeds from TAFIRI or other governmental stations. The absence of manufactured fish
feed is caused by a low and scattered demand, mainly due to lack of knowledge on feed and feed
management at the farm and the benefits accrued from using manufactured feeds.
3.5.3 Institutional setting
The Fisheries Development Division, under the Ministry of Livestock and Fisheries Development
(MLFD), is the designated Competent Authority in all matters pertaining to fish and fishery products.
This is in accordance with the Fisheries Act No. 22 of 2003 and Fisheries Regulations of 2009 and the
Fisheries (Laboratory Fees) Regulations of 2012. Among other things, the Fisheries Development
Division is responsible for monitoring, control and surveillance of fishing, efficient fisheries resources
utilization, marketing, and the certification of fish and fishery products and ensures that they meet
national and international quality and safety standards requirements.The Department of Aquaculture
Development (DAD) under the MLFD was established in September 2008, to oversee aquaculture
development in the country. Following its establishment, DAD has put in place National Aquaculture
Development Strategy (NADS) which is currently at implementation stage. The Department has two
sections, a fresh water aquaculture section and marine aquaculture section (see annex 5).
The National Fish Quality Control Laboratory (NFQCL) Nyegezi, Mwanza which is under the Fisheries
Development Division in the MLFD was established in 1997. NFQCL is responsible with safety and
Quality assurance of the fish and fish products in order to comply with the national Fisheries
Legislation and the international market standards and requirements. The NFQCL achieved its
accreditation status in 2007 through South African National Accreditation System (SANAS). This was
purposely done in order to increase consumer’s confidence with the safety of the fishery products
exported from Tanzania to foreign markets such as the European Union (EU) member countries,
United States of America (USA), Japan and Australia. In order to meet this obligation, the NFQCL is
required to comply with ISO/IEC 17025 standards. The Quality system undertaken by the laboratory
ensures that the requirements of the standards ISO 9001 and ISO/IEC 17025 are met.
Other governmental bodies related to fisheries & aquaculture include the National Environment
Management Council (NEMC), the Marine Parks and Reserves Unit (MPRU), the Board of External
Trade (BET), and the Tanzania Foods and Drugs Authority (TFDA), see for detailed description
Annex 6.
Tanzania Fisheries Research Institute (TAFIRI) was established by the Act of Parliament No. 6 of 1980
to promote, conduct, and co-ordinate fisheries research in Tanzania. This is the only Fisheries organ
mandated by the government to carry out different researches on fisheries matters. Its core functions
include carrying out research in the fields of fisheries statistics and stock assessment; Fish biology,
taxonomy and fisheries of commercially important fish species; Socio-economic and marketing;
Hydrobiology and water pollution; Gear technology and Aquaculture.
Department Aquatic Sciences and Fisheries of the University of Dar es Salaam was established in April
2009 from the two teaching departments that existed in the former Faculty of Aquatic Sciences and
Technology (FAST) following the restructuring of the University of Dar es Salaam that resulted in
