 Fish meal  as animal feed  – Specification                    TBS/AFDC 09 (5549) P3 
 
0 FOREWORD  
Fish meal is a rich source of high -quality protein and contains Calcium and 
Phosphorus. Since the fish meal available in t he country shows wide variations in 
its quality, it is felt that formulation of this standard would ensure production of 
fish meal of a uniform quality for use in the manufacture of animal feeds.  
 
In the preparation of this Tanzania  Standard substantial assistance was drawn 
from  
IS 4307:1973  – Specification for fish meal as livestock feed published by 
Indian Standards Institution.  
 
MS 227:1981 – Specification for fish meal  publishe d Standards and 
Industrial Research  Institute of Malaysia.  
 
In reporting th e results of a test or analysis made in a ccordance with this 
Tanzania  Standard, if the final value observed or calculated is to be rounded off, 
it shall be  done in accordance with TZS 4 (see clause 2).  
 
1.0 SCOPE  
 
This Tanzania  Standard prescribes the require ments, methods of sampling  and 
test for  fish meal  as animal feed .
