| Symbiosis is a form of animal life that lives two lives and their lives
play another hand is dependent on service. In this study, the symbiosis
relation between barnacle Chelonibita patula on blue swimming
crab Portunus. segnis from Persian Gulf coasts (Boushehr Province)
was studied. A total of 571 crabs different size ranges in random were
examined. The samples after freezing at -20 ° C transfered to laboratory
for analysis. After separating the samples were initially identify
the gender of the abdomen. After this phase, biometric characteristics
of the samples, including body weight, carapace length and width
were measured. The effect of gender, season and size distribution of
barnacles on the carapace was measured. The number of barnacles
on each crab varied from two to twenty-three. The condition factor
was in crab species with range of 3.5 to 8 (mean 6.04). The results
showed a significant difference between the sexes abundance of barnacles
(P < 0.05), so that the distribution and density were more in
females samples. The results showed that by increasing the carapace
width of crabs the accumulation of barnacles will increase. Frequency
barnacles in different seasons showed that the most frequent in winter
during the spawning crabs and the lowest rate was observed in spring
when the spawning period. The relationship between both crustaceans
is a cooperative relationship, that is especially barnacles crab carapace
levels as their environment and they do all production activities, reproductive,
nutritional and metabolic itself on crabs, instead crab with
barnacles camouflage and little attention is placed predators. |
