05). Likewise, the gas diffusion distance (1.24 ± 0.36 μm) became significantly shorter (P less then 0.05). Lactate dehydrogenase activity of gill in the air-exposed group (846.68 ± 88.78 U mg-1 protein) significantly increased after 7 days whereas succinate dehydrogenase (1.02 ± 0.21 U mg-1 protein) and Na+/K+ ATPase (0.57 ± 0.20 U mg-1 protein) activity decreased significantly (P less then 0.05). However, there was no significant change in the hindgut. After recovery, there was no significant difference in lactate dehydrogenase, succinate dehydrogenase, and Na+/K+ ATPase activity in the gill or hindgut in groups. P. dabryanus had a high viability in air-exposed condition. When recovery occurred under normoxic conditions, the physical levels of respiration returned back to the normal level quickly.A wild-caught stock of greater amberjack Seriola dumerili reared in sea cages in two commercial aquaculture facilities in Greece was administered gonadotropin-releasing hormone agonist (GnRHa), loaded in controlled release implants, and was used in spawning induction experiments throughout the reproductive season. Sperm quality was evaluated using computer-assisted sperm analysis (CASA) before and after GnRHa administration and the extent of the spermiation period was determined. Males were in spermiation throughout the monitoring period from May 30 until July 18, at temperatures between 19 and 24 °C. However, lower sperm motility duration, density, and survival under cold storage were observed from early July onwards. Sperm quality did not recover after the end of spawning induction experiments in tanks and the return of the fish for 14-28 days to the sea cage in mid-July, which could be related to the high temperatures of this period. An improvement trend was observed in the quality of the milt collected on day 7 after a single GnRHa administration, but a significant decrease was observed on day 21 in sperm density, survival under cold storage, and straight line velocity (VSL). On the contrary, a double GnRHa administration spaced 14 days apart maintained the same sperm quality for a longer period of 29 days. Further spermiation enhancement experiments should be conducted in the future to describe in more detail the kinetics of sperm production after GnRHa therapy and its effects on sperm quality.B cell activating factor (BAFF), belonging to the tumor necrosis factor superfamily (TNFSF), is a critical cytokine for B cell survival and immunoglobulin secretion. Here, the BAFF gene of Chinese sucker (Myxocyprinus asiaticus) (MaBAFF) was cloned using RT-PCR and RACE (rapid amplification of cDNA end) techniques. Selleck SB431542 The open reading frame (ORF) of MaBAFF encodes a 272-amino acid protein containing a transmembrane domain, a TNF family signature, and a putative furin protease cleavage site as seen in BAFFs from other species. Tissue expression profiles of MaBAFF determined by absolute and relative quantification of real-time quantitative PCR (qPCR) showed that MaBAFF is widely distributed in various tissues, with the highest expression in spleen. MaBAFF can be detected during fertilized egg period by RT-PCR. Upon induction by A. hydrophila, the expression of MaBAFF was up-regulated in spleen from 48 to 72 h, and the expression of BAFF and IgM all reached a peak at 48 h in head kidney. The soluble BAFF gene (MasBAFF) had been cloned into pET30a. SDS-PAGE and Western blotting analysis confirmed that the His-MasBAFF was efficiently expressed in Escherichia coli Rosset (DE3). CCK-8 assay indicated that the MasBAFF recombinant protein (200 ng/ml) could prolong the survival of peripheral blood leukocytes. Based on ELISA screening and Western blotting, monoclonal antibody 1-F2A3 against recombinant MasBAFF was selected and used for immunohistochemistry, which showed that BAFF-positive cells were detected in spleen and head kidney. Our results raise the possibility that MaBAFF may be useful to enhance immune efficacy in Chinese sucker disease defense.Although silver nanoparticles (AgNP) are among the most studied nanomaterials by virtue of their broad application in many areas, little is known about their overall toxicity to aquatic organisms after their contamination of the water environment. This study aimed to analyze the effect of the exposure (96 h) to different AgNP concentrations on Danio rerio (zebrafish) tissues. AgNP were synthesized and characterized by transmission electron microscopy (TEM), showing spherical AgNP of 30.00 ± 16.80 nm size. The effects of different AgNP concentrations (1, 3, and 5 μg L-1) on brain, muscle, gill, and liver tissues of zebrafish were investigated. The results show a significant decrease in brain and muscle acetylcholinesterase (AChE) activity. Liver and gill catalase (CAT) activity also decreased significantly. At the highest exposure concentration, muscle AChE was more inhibited (37.3%) than brain AChE (26.4%) and gill CAT was more inhibited (67.4%) than liver CAT (51.2%). D. rerio also showed gill morphological changes such as fusion of secondary lamellae, curvature, dilated marginal channel, and epithelial lifting. This study indicates that gill CAT together with morphological studies are potential biomarkers for AgNP.This study investigated the effect of stocking density on growth performance, blood biochemical profiles, antioxidative capacity, and muscle quality of gibel carp (Carassius gibelio). Gibel carps (initial body weight 57.04 ± 1.89 g) were reared at high stocking density (HSD, 10.85 kg m-3), medium stocking density (MSD, 5.06 kg m-3), and low stocking density (LSD, 1.47 kg m-3) for 60 days. The LSD group exhibited the highest growth rate, while HSD significantly inhibited fish growth. The muscular compositions of crude fat, crude ash, and moisture were significantly changed by stocking density, but crude protein content did not differ significantly. The stocking density altered the muscular texture profiles of gibel carp. Compared to either the HSD group or the MSD group, the highest levels of resilience and springiness occurred in the LSD group. Significant differences were observed in the levels of plasma glucose, alanine aminotransferase, aspartate aminotransferase, cholesterol, and creatinine among three groups.
