“…The liver in A. hormuzensis consists of single lobe, which is in contrast to the zebrafish that has a liver encompassing three lobes (Menk et al, 2011;Figure 15). The liver cells (or hepatocytes) in A. hormuzensis are not structured in cords or lobules, while in some other teleosts like Hypostomus francisci (Siluriformes), the liver cells were organized in cord form, and in Hoplias malabaricus (Characiformes) were polyhedral and organized in tubular form (Camila et al, 2017).…”

The histomicroscopy and normal anatomy of the major body organ systems were investigated in the adult killifish, Aphanius hormuzensis using histological examination, X‐ray imaging, double staining, light microscopy and scanning electron microscopy (SEM). Based on the histomicroscopic observations, the kidney, liver and swim bladder in the studied species were comparable to other fish models. The anterior portion of the kidney is bulbous, while the posterior portion is narrow and elongated; the liver has a single lobe and the swim bladder is a single‐chambered organ with no connection to the digestive tract (physoclistous). X‐ray imaging and double staining examination showed 12 abdominal and 15 caudal vertebrae and a single hypural plate in the caudal skeleton. According to light microscopy, the scales were rounded to pentagonal in shape with three types of radii (primary, secondary and tertiary), and the urohyal bone was elongated. SEM microscopy showed a single row of tricuspid teeth on the upper and lower jaw, respectively, each tooth has two lateral cusps that are shorter than the middle one. The number of teeth was 17–18 in the upper jaw and 19–20 in the lower jaw. The saccular otoliths were rounded‐trapezoid in shape with a moderately incised and V‐shaped excisura. The members of killifishes are an important group for biologists because of their evolutionary properties, regeneration capacity and usefulness as biological control and also for the ecotoxicological assessment of environmental pollution. The outcomes of this study may provide a useful basis for future research on the genus Aphanius.

“…MMCs are reportedly absent in the lamprey, Lampetra fluviatilis , but present in hagfish ( 6 ) (Figure 2 ; Tables S1 and S3 in Supplementary Material). We are aware of only two bony fish species that reportedly lack MMCs: the fifteenspine stickleback, Spinachia spinachia , and the South American armored catfish, Hypostomus francisci (Figure S1 and Table S3 in Supplementary Material) ( 8 , 59 ). In all three instances, MMC absence was determined by survey studies of a few individuals from a single location.…”

Melanomacrophage Centers As a Histological Indicator of Immune Function in Fish and Other Poikilotherms

2017

View full text Add to dashboard Cite

Melanomacrophage centers (MMCs) are aggregates of highly pigmented phagocytes found primarily in the head kidney and spleen, and occasionally the liver of many vertebrates. Preliminary histological analyses suggested that MMCs are structurally similar to the mammalian germinal center (GC), leading to the hypothesis that the MMC plays a role in the humoral adaptive immune response. For this reason, MMCs are frequently described in the literature as “primitive GCs” or the “evolutionary precursors” to the mammalian GC. However, we argue that this designation may be premature, having been pieced together from mainly descriptive studies in numerous distinct species. This review provides a comprehensive overview of the MMC literature, including a phylogenetic analysis of MMC distribution across vertebrate species. Here, we discuss the current understanding of the MMCs function in immunity and lingering questions. We suggest additional experiments needed to confirm that MMCs serve a GC-like role in fish immunity. Finally, we address the utility of the MMC as a broadly applicable histological indicator of the fish (as well as amphibian and reptilian) immune response in both laboratory and wild populations of both model and non-model vertebrates. We highlight the factors (sex, pollution exposure, stress, stocking density, etc.) that should be considered when using MMCs to study immunity in non-model vertebrates in wild populations.

“…The fish liver is described as a multifunctional organ that acts in detoxification, the production of vitellogenin and the deposition and metabolism of carbohydrates and fat (Sales et al, 2017). Studies on the metabolic interactions between the liver and muscle are important to understand how dietary changes might affect fish metabolism (Kumar, Makkar & Becker, 2010).…”

Dietary limonCitrus × latifoliafruit peel essential oil improves antioxidant capacity of tambaqui (Colossoma macropomum) juveniles

The effects of dietary supplementation with Citrus × latifolia essential oil (EOCL: 0, 0.25, 0.5, 1.0 and 2.0 ml EOCL/kg diet) on growth, survival, gut tract morphology and the metabolic and oxidative parameters of tambaqui (Colossoma macropomum) were investigated in a 60‐day experiment. The inclusion of up to 2.0 ml EOCL/kg diet did not promote growth; however, fish fed 1.0 and 2.0 ml EOCL/ kg diet presented higher survival and all EOCL groups had increased intestinal fold height and length compared to the control group. After 60 days of experiment, glucose, glycogen, lactate and protein levels in the liver and muscle were altered significantly by dietary addition of EOCL. The muscle LPO content was higher in fish fed 2.0 ml EOCL/ kg diet than the control group. The reactive oxygen species content was higher in the liver but lower in the muscle of fish fed 1.0 ml EOCL/kg diet compared to the control group. SOD activity was higher in the liver of fish fed 0.50 and 1.0 ml EOCL/kg diet than the control group. Therefore, dietary addition of 1.0 ml EOCL/kg diet is advisable for tambaqui juveniles since it improved survival, the antioxidant capacity of tissues and the intestinal absorption area.
