Batch fecundity of the swimming crab Portunus trituberculatus (Brachyura: Portunidae)

Aquaculture, 2006
Abstract We assessed batch fecundity of the swimming cab Portunus trituberculatus for the purpose of seed production. Oocyte number and number and body size of first zoeas were examined for females collected from natural habitats in the Seto Inland Sea of Japan.

Morphology and phylogeny of Ameson portunus n. sp. (Microsporidia) infecting the swimming crab Portunus trituberculatus from China

European Journal of Protistology, 2017
Ameson portunus n. sp. is a new microsporidian species that infects the skeletal muscle of Portunus trituberculatus, a pond-reared swimming crab from China. This parasite was characterized using morphological and molecular phylogenetic data. Light and transmission electron microscopy revealed that this microsporidian experienced disporogonic and ...

cDNA cloning, characterization and expression analysis of catalase in swimming crab Portunus trituberculatus

Molecular Biology Reports, 2012
Catalase is an important antioxidant protein that protects organisms against various oxidative stresses by eliminating hydrogen peroxide. In the present study, a full-length cDNA sequence of catalase was cloned from the haemocytes of swimming crab Portunus trituberculatus by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid ...

Molecular cloning and characterization of prophenoloxidase gene in swimming crab Portunus trituberculatus

Fish & Shellfish Immunology, 2010
Phenoloxidase (PO), a melanin-synthesizing enzyme, found as a zymogen (proPO) in hemolymp, plays an important role in arthropod defence. In this study, a prophenoloxidase (proPO) cDNA was cloned from the haemocytes of swimming crab Portunus trituberculatus by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA end

Eighteen novel polymorphic microsatellites for the swimming crab (Portunus trituberculatus)

Conservation Genetics Resources, 2012
Eighteen novel polymorphic microsatellite loci were isolated from the swimming crab, Portunus trituberculatus, and characterized in a cultured stock of swimming crab. The number of alleles varied between two and four, and the observed and expected heterozygosity at population level ranged from 0.1481 to 0.8621 and 0.4898 to 0.7475, respectively.

Transcriptome analysis of different stages of testis development in Portunus trituberculatus

Comparative Biochemistry and Physiology Part D: Genomics and Proteomics
The swimming crab (Portunus trituberculatus) is an important marine economic species, however its artificial breeding yield is relatively low. Currently, the main challenge faced by the swimming crab seed industry is the reliance on wild populations for seed cultivation, which results in unstable yield and quality, affecting the healthy development of ...

Cloning and expression of arginine kinase from a swimming crab, Portunus trituberculatus

Molecular Biology Reports, 2011
Arginine kinase (AK) is an important phosphotransferase that plays a critical role in energy metabolism in invertebrates. In this paper, the cDNA of AK (designated as PtAK) was identified from the eyestalk cDNA library of swimming crab Portunus trituberculatus.

Dietary protein requirements of the juvenile swimming crab, Portunus trituberculatus

Aquaculture, 2013
Abstract An 8-week feeding trial was conducted to determine the optimal dietary protein requirements for juvenile swimming crabs ( Portunus trituberculatus ) reared in cement pools. Six iso-energetic and iso-lipidic experimental diets were formulated to contain graded levels of protein, and these dietary protein levels were 31.6, 36.5, 41.7, 45.6, 50.

[Stable isotope ratio characteristics and origin tracing of Portunus trituberculatus].

Ying yong sheng tai xue bao = The journal of applied ecology, 2021
A method for geographical discrimination of Portunus trituberculatus was explored to provide technical support for the protection of geographical indication products and for tracing the origin of seafood. P. trituberculatus were collected from three major production areas, including the Yellow Sea, the Bohai Sea, and the East China Sea.

Acute metabolic response of Portunus trituberculatus to Vibrio alginolyticus infection

Aquaculture, 2016
Abstract Vibrio alginolyticus is a common pathogen that causes vibrio disease in swimming crab, Portunus trituberculatus . An understanding of the metabolic response mechanism of swimming crab to V. alginolyticus is essential for further control of this disease.
