2.3 Milk fish cage culture
Floating cages were constructed in the following dimensions of 3’ x 4’ x 2’. Frame was made out of
metal and covered with plastic coated galvanized wire mesh (Figure 6). Fish cages are set up in
shallow water at the depth with appropriate floats and anchors. Then the standard length and weight
of the fries were measured; before caging the fries permit to acclimate (Figure 7). Every cage is
seeded with 30 fingerlings and cages are maintained by the selected families of dirt that cling to the
cage was removed on weekly basis by brushing manually to enhance the natural free flow of water
for feeding. Weight and standard length of fingerlings along water quality were measured
fortnightly. From the average readings obtained from each cages, a final average reading was
obtained. After 6 month of farming cycle harvest was made, the weights and standard lengths of
fish were measured and results compared with natural fish. In addition, the cost of expenditures of
and the income from the milk fish sales were calculated to estimate the net profit per cage.
