dc.description.abstract | The study was aimed to evaluate the effect of stocking density on the growth and survival
rate of razor clam Cultellus maximus at the grow-out stage. The experiment was conducted
at density of 10, 20, and 30ind/m2 with three replications. The juvenile razor clam C. maximus
with an initial length of 5.10 ± 0.8 cm (4.34 ± 1.19g)/ per individual were chosen. Growth in
live weight and shell length was measured weekly for the three different stock groups. Water
quality parameters as temperature, salinity, pH, TAN, NO2, NO3, kH and H2S were in a suitable
range for razor clam culture. After 16 weeks of culture, the results indicated that the most
significant length of 9.63 cm and weight 21.31 g was obtained from the treatment 10 ind/m2
and the highest survival rate in the treatment, up to 82 ± 2 %. There was a significant
difference among the three treatments for growth and survival rate (p < 0.05). Our findings
suggested that juvenile razor clam C. maximus should be stocked at the level of 10 ind/m2.
However, further studies are needed in different locations to ensure the effectiveness of low
stocking density in each region. Our results provide a reference standard for farmers and
future studies. | en_US |
