The aim of the present study was to purify and characterize a toxic protease secreted by the pathogenic Photobacterium damselae subsp. piscicida strain CP1 originally isolated from diseased cobia (Rachycentron canadum). The toxin isolated by anion exchange chromatography, was a metalloprotease, inhibited by L-cysteine, ethylenediaminetetraacetic acid (EDTA), ethylene glycol-bis(beta-aminoethyl ...

The aim of this study was to assess the ecological factors associated with feeding by Rachycentron canadum (cobia) in the waters of Hormuzgan Province, Iran. Specimens were collected seasonally from Sep. 2014–Sep. 2015 from the Ferdows-1 survey ship and from landing areas in the city of Bandar Abbas. A total of 577 cobia were collected (340 male, 237 female) (20–161 cm Total length). Our result...

The vasa gene is essential for germ cell development and gametogenesis both in vertebrates invertebrates. In the present study, (Rcvasa) cDNA was cloned from cobia (Rachycentron canadum) using RACE amplification method. We found that full-length sequence of Rcvasa comprises 2571 bp, containing a 5′-UTR 145 3′-UTR 341 an open reading frame (ORF) 2085 encoding protein 694 aa. deduced amino acid c...
