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 کاملBehavioural evidence for colour vision in an elasmobranch.
Little is known about the sensory abilities of elasmobranchs (sharks, skates and rays) compared with other fishes. Despite their role as apex predators in most marine and some freshwater habitats, interspecific variations in visual function are especially poorly studied. Of particular interest is whether they possess colour vision and, if so, the role(s) that colour may play in elasmobranch vis...
متن کاملFirst genetic linkage map for the mud crab (Scylla paramamosain) constructed using microsatellite and AFLP markers.
The mud crab (Scylla paramamosain) is of economic importance for the fisheries and aquaculture industry in China. In this study, we constructed the first genetic linkage map for this species using microsatellite and amplified fragment length polymorphism (AFLP) markers. The map consisted of 65 linkage groups, including 34 triplets and 9 doublets. A total of 212 molecular markers were mapped, in...
