 Foreword  
 
Development of the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in Ea st Africa. It is envisaged that through harmonized 
standardization, trade barriers which are encountered when goods and services are exchanged within the 
Community will be removed.  
 
In order to meet the above objectives, the EAC Partner States have enacte d an East African Standardization, 
Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring 
standardization, quality assurance, metrology and testing of products produced or originating in a third country 
and tra ded in the Community in order to facilitate industrial d evelopment and trade as well as helping to 
protect the health and safety of society and the environment in the Co mmunity.  
 
East African Standards are formulated in accordance with the procedures estab lished by the East African 
Standards Committee. The East African Standards Committee is established under the provisions of Article 4 
of the EAC SQMT Act, 2006. The Committee is composed of representatives of the National Standards 
Bodies in Partner States , together with the representatives from the private sectors and consumer 
organizations. Draft East African Standards are circulated to stakeholders through the National Standards 
Bodies in the Partner States. The comments received are discussed and incorp orated before finalization of 
standards, in accordance with the procedures of the Community.  
 
Article 15(1) of the EAC SQMT Act, 2006 provides that “Within six months of the declaration of an East African 
Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East 
African Standard as a national standard and withdraw any existing national standard with similar scope and 
purpose”.  
 
East African Standards are subject to review, to keep pace with technological a dvances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing.

 Introduction  
Fish feed s are essential for semi -intensive and intensive aquaculture farming systems. Fish nutriti on has 
therefore become one of the most important subjects in aquaculture. Aquaculture nutrition and feeding is 
concerned with the supply of dietary nutrients to fish either directly in the form of an exogenous ‘artificial’ diet 
or indirectly through the i ncreased production of natural live food organisms within the water body in which the 
fish are cultured. Natural food organisms, play a crucial role in the nutrition of fish within extensive and semi -
intensive pond culture systems. In the intensive culture  systems, with high stocking density natural food 
organisms play little or no role in the nutrition of the farmed species. The nutrition and feeding of fish within 
each culture system must be considered as being unique and evaluated on its own merits.  
Additionally, the nutrient requirements for fish feeds will inevitably vary between omnivorous and carnivorous 
fish. Omnivorous fish will eat almost anything from vegetable and plant matter, insects, crustaceans and meat 
proteins while carnivor ous fish eat mea t only.  
Feeds may be produced by mixing various feeding stuffs or ingredients which may themselves vary in 
compositi on.  The choice of raw material  mixtures will depend on locality, season and availability, economics 
and the quality of the product. The c hemical composition of feedstuffs play s an important role in  the 
formulation of balanced and economical rations for various classes of animals. This is only possible when 
exact knowledge of the chemical composition of feedstuffs is available. Studies on the nutritive value of 
feedstuffs available in the East African region show differences between analytical values.
