open access: yesJournal of Fisheries and Aquatic Science, 2012
The study were aim to demonstrate the affects of live food type’s i.e., mixed diatom, Artemia nauplii and rotifer on survival rate and molt time of larvae stage till 1st day juvenile crabs (C1) of P. pelagicus. Three types of feeding regimes given to the crab larvae through out the study trials are with and without mixed diatom, with and without ...

Reproduction and Larval Ecology of the Blue Swimming Crab Portunus pelagicus in Ragay Gulf, Philippines

Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1989
AbstractThe Ragay Gulf situated at the southeastern part of Luzon is an important fishing area especially for the blue crabs. Commercial landings are caught by traps, gillnets and trawls. Most prevalent catching method is by means of baited traps called “Bubo” in Pilipino. Landings fluctuate yearly and were 641 t in 1984 and 210 t in 1985.

The occurrence of luteinizing hormone-like molecule and its receptor in the blue swimming crab, Portunus pelagicus

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology
Knowledge of the neuroendocrine system possibly improves the reproductive performance of captivated crustacean broodstock in aquaculture and it may substitute eyestalk ablation. In this study, we explored the luteinizing hormone (LH)-like molecule and proved the existence of the LH receptor (PpelLHR)-like mRNA in the blue swimming crab, Portunus ...

The complete mitogenome of blue swimming crab Portunus pelagicus Linnaeus, 1766 (Crustacea: Decapoda: Portunidae)

Mitochondrial DNA Part A, 2015
The complete mitochondrial genome (mitogenome) of the blue swimming crab Portunus pelagicus Linnaeus, 1766 (Crustacea: Decapoda: Portunidae) was determined in this study. The full length mitogenome is 16 157 bp in size, and consists of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and a non-coding control region, with the base composition of ...

Genetic diversity and population structure of the blue swimming crab Portunus pelagicus in Thailand

Genetic diversity and population differentiation of the blue swimming crab (Portunus pelagicus) in Thai waters was examined by SSCP analysis. Thirty eight primers pairs were initially tested against genomic DNA of P. pelagicus (N = 3). The positive amplification product of cytochrome oxidase subunit I (COI), M122/135RAP and P[subscript +3]4M[subscript +

Development of the Larval Stages of the Blue Swimming Crab Portunus pelagicus L. (Portunidae : Decapoda : Crustacea)

Marine and Freshwater Research, 1979
The four zoeal stages and megalopa of P. pelagicus were reared in culture and are described. Each appendage or structure is described showing the changes that occur during the zoeal phase. P. pelagicus larvae have similar types and location of setae as the larvae of P. spinicarpus. The positions of the chromatophores in the zoeal stages are described.
