Over 200,000 of Clarias gariepinus two-week
old hatched fry were sorted at different ages i.e 2, 3, 4, 5 and 6 weeks
using nine differet grading tools, namely Dipnet (DN), grading cage (GC), hang
grading net (HGN), meshed box (MB), plastic basin (PB), plywood box (PWB),
sorting table (ST), woven basket (WB), and wood grading panel (WGP). The result
from the study indicated that sorting table (ST), grades faster in all the age
of the fry, having the highest number of graded fry. In all the ages, plastic
basin (PB) consistently had the lowest. The highest mortality values were
observed in sorting table (ST) in all the ages of fish sorted while the lowest
values were recorded in grading cage (GC). The success of the grading cage (GC)
was that it grades more efficiently through the bottom unlike other sorting
tools which gradel through its sides. Clarias
gariepinus fry between the age of 2 and 4 weeks is best graded using the
grading cage for high survival rate and sorting table is best used with fish
from the age of 4 weeks and above.
