  • Histological structure of the skin in five fish species of Periophthalmus waltoni (Gobiidae) Silurus triostegus (Siluridae), Heteropneustes fossilis (Heteropneustidae), Mastacembelus mastacembelus (Mastacembelidae) and Coptodon zilli (Cichlidae)

    The five fish species viz. Periophthalmus waltoni, Silurus triostegus, Heteropneustes fossilis, Mastacembelus mastacembelus, and Coptodon zilli were collected in the Shatt Al-Arab River from February to June 2019. The samples were transferred to the laboratory to measure their total lengths and weights. To examine the skin histology and structure in these fishes, a skin sample was taken from the dorsal part close to the lateral line. The results showed that the skin of fish contains two layers: the first is the epidermis, which includes the epithelium. The thickness of the tissue in fish varied from 3 to 20 layers. In this layer, there are mucous cells that were spared and varied in their abundance from one species to another. The dermis includes two layers of stratum spongiosum and stratum compactum. These two layers consist of pigment cells that spread directly under the epidermis in a dark brown color. In C. zilli and H. fossilis, a third layer was found under stratum compactum as hypodermis; the highest thickness of the dermis was recorded in C. zilli.
  • Otolith mass asymmetry in three sparid fish species collected from the Iraqi waters

    Saccular otolith mass asymmetry is examined in three sparid fish species, Acanthopagrus bifasciatus, A. arabicus, and Sparidentex hasta collected from Khor Abdullah at the North Persian Gulf. This characteristic was computed as the disparity between the weight of the right and left otoliths divided by mean otolith weight in the three sparid species investigated. According to the previous cases obtained on another symmetrical fish species, the absolute value of x in these species does not determine by fish length and otolith growth ratio, while the absolute rate of otolith weight disparity is boosted with the fish length. The estimate of x was between -0.2 and +0.2. Otolith mass asymmetry can show some growth disorder of fish owing to environmental influence.
  • Asymmetry in the otolith length and width of three sparid fish species collected from Iraqi waters

    Marine Pollution Bulletin, 2020
    Bilateral asymmetry is presumed to reveal the developmental variability of the fish in polluted aquatic environments. In these habitats, high-level asymmetry develops, and these fish expend more energy to balance their growth than fish that are not under an impact. A total of 210 specimens of Acanthopagrus bifasciatus, A. latus and Sparidentex hasta were collected from the marine waters of Iraq in the northwest part of the Arabian Gulf. The asymmetry was calculated for the sagittal otolith characters of length and width. Otolith width has lower asymmetry than otolith length for the three sparid fish species investigated. An increase in the value of fluctuating asymmetry with fish length was observed. This could be a pertinent indicator of pollution in the habitat.
