The embryonic development of orange mud crab, Scylla olivacea (Herbst, 1796) held in the captivity
This study attempts to observe and record early embryonic developments of the orange mud crab, Scylla olivacea. The period taken by the eggs to hatch was 8 days and the colour of the eggs gradually changed from yellow to brown, gray and dark gray. During the embryonic development, the developing embryos reached the blastula stage within 24 hours with a mean egg diameter of 329.91 µm ± 6.62. The...

متن کاملThe Population dynamics of mud crab (Scylla serrata) in coast of Bandar Khamir (Hormozgan Province)
The Sampling one-year period from October 92 to October 93 on a monthly basis was conducted using gillnets and baited traps. 70% of gillnet catches during flood tide consisted of adults. Sub-adults and juveniles were 28 % and 4.5%, respectively. Similarly, during ebb tide consisted of 51.7%, 24.2%, and 24.1%, respectively. It suggests that gillnets are not sized selective gear. In contrast, bai...
متن کاملEcdysone receptor in the mud crab Scylla paramamosain: a possible role in promoting ovarian development.
In arthropods, it is known that ecdysteroids regulate molting, limb regeneration, and reproduction through activation of the ecdysone receptor (EcR). However, the ecdysteroid signaling pathway for promotion of ovarian development in crustaceans is still unclear. In this study, three cDNA isoforms of EcR were cloned from the mud crab Scylla paramamosain. qRT-PCR revealed that the SpEcR mRNA was ...
متن کاملRapid isolation and characterization of polymorphic microsatellite loci in the mud crab, Scylla paramamosain (Portunidae).
Scylla paramamosain is a widespread and commercially important species of coastal marine crab. We identified 13 polymorphic microsatellite loci from a genome library constructed with 5'-anchored PCR method. Thirty-two S. paramamosain from the East China Sea were used to analyze the characteristics of these loci. The number of alleles per locus ranged from 3 to 8, with a mean of 5.923. Observed ...
