摘要：In this study, three shelter types (no shelter, mesh and pipe shelter) were used to evaluate
growth, survival and feed conversion ratio on juvenile Astacus leptodactylus. A. leptodactylus
with an average weight of (25.4 ¡À0.52 mg) and an average total length of (14.00 mm ¡À0.03)
were used for this study. This experiment was conducted in a total of 12 aquaria of 100 L each
of 80 x 40 x 25 cm (length x width x height) and each aquarium was contained 10 young
crayfish. The experimental design was a 3x4 factorial arrangement, and treatments were
randomly assigned to the aquariums. This study was continued 90 days experimental period.
There is a relationship between shelter type and survival. Survival was significantly different
among the groups. The highest survival (85.0%) was obtained using mesh as shelter, while the
poorest survival (40.4%) was observed without shelter. .n addition; the survival was 67.5%
were found in pipes groups. Final length and weight were found significantly different among
the shelter groups and the best growth was observed net shelter groups. No significant
differences were observed feed conversion ration among the shelter groups. The highest yield
(176.8 g) was obtained using mesh net shelter, while the lowest yield (54.4 g) was found
without shelter (control) groups. Also, yield in pipes shelter groups was found 104. 76 g.
