  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Onur Karadal Abstract Red swamp crayfish ( Procambarus clarkii ) is an economic decapod species and the most cultivated crayfish in the world. In nature, this species can tolerate the hardy alterations, but they are vulnerable to water parameters in culture conditions. Crayfish have to molt to grow, and the non-renewable shell is a suitable surface for pathogenic activities until the next molt. In this study, melanized lesions were determined in red swamp crayfish from several parts of body exoskeleton: cephalothorax, abdominal shell, uropods, walking legs, swimmerets, and antennae. The bacteriological and mycological isolations were conducted onto tryptic soy agar, brain heart infusion agar, Sabouraud’s dextrose agar and glucose yeast agar, but no particular microbial growth was observed from cultured samples. The aetiology of the case was not associated with any bacterial or fungal agent

  Oceanography & Fisheries Open Access Journal Juniper Publishers Authored by: Mohammad Shafi Abstract The current study aimed to investigate the morphometric analysis based on length and weight relationships and condition factors of six sole fish species i.e., Cynoglossus punticeps, C. arel , C. quadrilineatus , Pseudorhombus javanicus , P. elevates , and Euryglossa orientalis belong to three different families Paralichthyidae, Cynoglossidae and Soleidae. Their feeding practices are quite different from other species as they forage mostly on bottom invertebrates, therefore, these species inhabiting in shallow muddy and sandy bottom of the continental shelf along the coast. Sole fish species were collected from five harbors i.e., Karachi fish harbor (KAH), Keti Bandar fish harbor (KBH), Korangi fish harbor (KOH), Ormara fish harbor (OFH) and Pasni fish harbor (PFH) along the coast. The significant variations were observed in morphometric parameters according to fish s
