Statocyst-Induced Eye Movements in the Crab Scylla Serrata*

Journal of Experimental Biology, 1972
ABSTRACT The fast and slow eye movements of nystagmus in crabs can be produced by moving a striped pattern around the animal or by rotating the animal in complete darkness. The discharges in the eye muscles are the same regardless of the method used to produce nystagmus.

Transport of Scylla serrata megalopae at various densities and durations

Aquaculture, 2000
Abstract The optimal conditions for transport of Scylla serrata megalopae were determined. Loading densities of 50, 100 and 150 ind l −1 of hatchery-reared megalopae were studied over a 6-h simulated transport, including shaking. Survival immediately after transport was significantly higher at 50 ind l −1 (99.3±1.6%) (mean± x %) than at 100 (93.0±

Identification and agglutination properties of hemocyanin from the mud crab (Scylla serrata)

Fish & Shellfish Immunology, 2011
Infectious diseases have significantly delayed the growth of crab aquaculture. Identification of the immune molecules and characterization of the defense mechanisms will be pivotal to the reduction of these diseases. Hemocyanin is an important non-specific immune protein present in the hemolymph of both mollusks and arthropods. However, little is known

Aspects of the feeding strategy of the predatory crab Scylla serrata

Marine Biology, 1979
Scylla serrata in a South African estuary occurred more frequently in that part which had the highest number of prey organisms. Food location was by contact chemoreception, using the dactyls of the walking legs. Major prey groups were burrowing bivalves, attached bivalves and small crabs. s. serrata showed a preference for small crabs as prey.

Effects of temperature on feeding and activity in the crab Scylla serrata

Marine Biology, 1980
The effect of temperature on feeding, duration of emergence and movement by the crab Scylla serrata (Forskal) was measured under laboratory conditions using infrared time-lapse photography. Little difference was found between experiments carried out at 25° and 20°C. All parameters measured declined at 16°C.

Study of epileptiform activity in cerebral ganglion of mud crab Scylla serrata

Invertebrate Neuroscience, 2011
An attempt is made to induce in mud crab (Scylla serrata) epileptiform activities that resemble the generalized epileptic seizures. Cerebral ganglion of crab was exposed in situ, to a convulsant drug pentylenetetrazole (PTZ) 100 mM, for induction of seizures.

Heart-rate of the crab Scylla serrata (Forskal) in air and in hypoxic conditions

Comparative Biochemistry and Physiology Part A: Physiology, 1975
Abstract 1. The heart-rate of the crab Scylla serrata in normoxic water but isolated from stimuli is initially 70 to 80 beats/min but declines to 25 to 35 beats/min after 72 hr. 2. Exposure to air causes rapid bradycardia; 50% of the initial heart-rate is reached after 7 to 18 hr. 3.

A new parasite that infects eggs of the mud crab, Scylla serrata, in Australia

Journal of Invertebrate Pathology, 2006
The mud crab, Scylla serrata, is currently being evaluated for its feasibility for mass aquaculture in Australia. As part of the evaluation process, pathogens that can affect this species need to be identified. This research note describes a possible new parasite that infects the eggs of S. serrata.
