Mating Behavior and Morphology of Imported Mexican Freshwater Crayfish (Cambarellinae: Cambaridae) in Japan

Freshwater Crayfish, 2021
Abstract In the present study, for the first time the Mexican freshwater crayfish reported in the Japanese aquarium pet trade is identified as Cambarellus patzcuarensis. This diagnosis is based on the morphological description of key characters, such as the gastric mill, mandible, and gill, which are also illustrated.

Complete primary structure of the molt-inhibiting hormone (MIH) of the Mexican crayfish Procambarus bouvieri (Ortmann)

Peptides, 1996
The amino acid sequence of MIH was elucidated by means of digestions with specific proteases, manual Edman degradation, and mass spectrometry. MIH consists of a 72-residue peptide chain (molecular mass 8322 Da) with six cysteines forming three disulfide bridges that connect residues 7-43, 23-39, and 26-52.

A neuropeptide family from the sinus gland of the Mexican crayfish, Procambarus bouvieri (Ortmann)

Aquaculture, 1995
Abstract The main neuroendocrine axis of crustaceans is constituted by the brain, medulla terminalis X-organ (MTXO) -sinus gland (SG) system. A variety of hormonal peptides are synthesized in the MTXO where the peptidergic neuronal somata are situated.

Primary structure of the major isomorph of the crustacean hyperglycemic hormone (CHH-I) from the sinus gland of the Mexican crayfish Procambarus bouvieri (Ortmann): Interspecies comparison

Peptides, 1993
The amino acid sequence of this neuropeptide was elucidated by means of a combined approach of enzymatic digestions, manual and automatic Edman degradations, and mass spectrometry. It is a 72 residue peptide (molecular mass 8388 Da), with six cysteines forming three disulfide bridges connecting residues 7-43, 23-39, and 26-52, with blocked N- and C ...

Amino acid sequence of the minor isomorph of the crustacean hyperglycemic hormone (CHH-II) of the Mexican crayfish Procambarus bouvieri (Ortmann): Presence of a d-amino acid

Peptides, 1995
The primary structure of the neurohormone crustacean hyperglycemic hormone (CHH-II) was determined by means of enzymatic digestions, manual Edman degradation, and mass spectrometry. CHH-II is a 72 residue peptide (molecular mass 8388 Da), with six cysteines forming three disulfide bridges that connect residues 7-43, 23-39, and 26-52.

Morphometric analysis of interspecific and microgeographic variation of crayfish from a Mexican cave

Biological Journal of the Linnean Society, 1992
Two undescribed species of Procambarus crayfish (Crustacea, Decapoda) inhabit the subterranean stream running in the recently explored Cueva de Los Camarones, Chiapas, Mexico. Individuals ranging from dark, robust, large-eyed forms with an epigean mien to pale, comparatively slender, microphthalmic ones resembling related troglobites were found, but ...

A neuropeptide with molt-inhibiting hormone activity from the sinus gland of the mexican crayfish Procambarus bouvieri (Ortmann)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1989
Abstract 1. 1. By means of reverse-phase high-performance liquid chromatography (RP-HPLC) on a μBondapak-Phenyl column, a neuropeptide with molt-inhibiting hormone (MIH) activity was isolated from a crude extract of 2000 sinus glands from the crayfish Procambarus bouvieri (Ortmann) with a yield of 25 ng/SG. 2. 2.
