By inserting
Telenet Fish Chaser |
The spawn got attained to Fry stage,
five days in advance when compared the development of spawn
to Fry in two nurseries i.e., one with inserting Fish Chaser
and another without inserting Fish Chaser. The percentage
of spawn to Fry realization was also more in the nursery
in which Fish Chaser was inserted. This is to be further
studied for strengtheting the technology.
This is to certify that the Fish Chaser
supplied by Telenet Company is working satisfactory as per
my observations explained in my statement.
