Abstract:

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, baited traps only caught adults and sub-adults with the percentage of 90.5% and 9.5%, respectively. The CW∞  and K of males were slightly higher than females namely 21.147 and 1.38 for males and 21.023 and 0.83 for females. The mortality estimates are as follows: natural mortality (M) male = 2.48 and fishing mortality (F) male =1.2, while M female =1.78 and F female = 0.75. The results show that S. serrata population is still less than underexploited.

Physico-chemical characterization of bacterial and hemagglutinins from the serum of the mud crab Scylla serrata

A naturally occurring hemagglutinin (HA), with activity against bacteria and yeast cells were detected in the serum of Scylla serrata using mammalian erythrocytes (RBC), various bacteria and yeast as indicator cells. The serum gave highest HA titer with rabbit RBC, tripsinized yeast and Vibrio fluvialis. An analysis of the physico-chemical properties of the HA showed it to be specifically depen...

Isolation and Identification of Acholeplasma sp. from the Mud Crab, Scylla serrata

For the first time, a mollicute-like organism (MLO) was cultured from moribund mud crabs (Scylla serrata) during an outbreak of clearwater disease in Zhejiang Province, China. The MLO displayed a fried-egg colony morphology in culture, did not possess a cell wall, and was not retained by 0.45 μm and 0.2 μm filters. It was able to ferment glucose, sucrose, lactose, and maltose, but it did not ut...

Preliminary Study on the Feeding Regime of Laboratory Reared Mud Crab Larva, Scylla serrata (Forsskal, 1775)

Survival of larvae of mud crab, Scylla serrata (Forsskal, 1775) is a persistent issue in the field of induced breeding of the species. A preliminary study was conducted on feeding regimes of laboratory reared larvae and juveniles of S. serrata. The results showed that the survival of the larvae fed with green water alone or green water with plankton and feed was not significantly different from...

Purification and characterization of antibacterial proteins from granular hemocytes of Indian mud crab, Scylla serrata.

Marine invertebrates depend upon antimicrobial peptides (AMPs) as a major component of innate immunity, as they are rapidly synthesized and diffuse upon pathogen invasion. In this study, we report the identification and characterization of a 11 kDa antimicrobial protein, which we name SSAP (for Scylla serrata antimicrobial protein), from granular hemocytes of the mangrove crab S. serrata. The p...

Biological evaluation of crab meat (Scylla-serrata) in the rat.

Shell-fish are of some significance in the human diet. Because of their high content of protein, low content of fat and high proportion of polyunsaturated fatty acids, they are commonly recommended in diets designed to treat atherosclerotic patients. However, little work on their nutritional value has been reported. Assessments of the biological value of different crab-meat preparations indicat...
