“…6). In early developmental stages, IgM is derived from the mother (Zhang et al 2013) and thus the IgM level in larvae and early stage juveniles is determined by that of the mother fish. As probiotics, neither Lactobacillus strain CICC 6141 nor L. casei BL23, when given access into the zebrafish, can stimulate B cell synthesis of IgM.…”

To increase the knowledge of probiotic effects on zebrafish (Danio rerio), we compare the effects of two probiotic strains, Lactobacillus rhamnosus CICC 6141 (a highly adhesive strain) and Lactobacillus casei BL23 (a weakly adhesive strain), on zebrafish reproduction and their offsprings' innate level of immunity to water-borne pathogens. During probiotics treatments from 7 to 28 days, both the Lactobacillus strains, and especially L. casei BL23, significantly increased fecundity in zebrafish: higher rates of egg ovulation, fertilization, and hatching were observed. Increased densities of both small and large vitellogenic follicles, seen in specimens fed either Lactobacillus strain, demonstrated accelerated oocyte maturation. Feeding either strain of Lactobacillus upregulated gene expression of leptin, kiss2, gnrh3, fsh, lh, lhcgr, and paqr8, which were regarded to enhance fecundity and encourage oocyte maturation. Concomitantly, the gene expression of bmp15 and tgfb1 was inhibited, which code for local factors that prevent oocyte maturation. The beneficial effects of the Lactobacillus strains on fecundity diminished after feeding of the probiotics was discontinued, even for the highly adhesive gut Lactobacillus strain. Administering L. rhamnosus CICC 6141 for 28 days was found to affect the innate immunity of offspring derived from their parents, as evinced by a lower level of alkaline phosphatase activity in early larval stages. This study highlights the effects of probiotics both upon the reproductive process and upon the offsprings' immunity during early developmental stages.

“…Such studies have greatly expanded our knowledge about the innate and acquired immune systems of aquatic animals [151][152][153][154][155]. In China especially, comparative immunological studies of aquaculture animals have flourished over the last 10 years, financial support for research in this area has increased, and progress in this field has been reported in several reviews [156][157][158][159][160][161][162]. Figure 2 is a schematic diagram outlining the interactions occurring between the diverse range of viruses discussed herein and their aquatic hosts.…”

Over the last 30 years, aquaculture has become the fastest growing form of agriculture production in the world, but its development has been hampered by a diverse range of pathogenic viruses. During the last decade, a large number of viruses from aquatic animals have been identified, and more than 100 viral genomes have been sequenced and genetically characterized. These advances are leading to better understanding about antiviral mechanisms and the types of interaction occurring between aquatic viruses and their hosts. Here, based on our research experience of more than 20 years, we review the wealth of genetic and genomic information from studies on a diverse range of aquatic viruses, including iridoviruses, herpesviruses, reoviruses, and rhabdoviruses, and outline some major advances in our understanding of virus-host interactions in animals used in aquaculture.

“…In fish, the reproductive cycle is marked by seasonal variation in plasma sex-steroids and by changes in immune parameters which render them more sensitive to the presence of pathogens [14]. Furthermore, immune biomarkers may prove useful for the identification of contamination in the wild [13].…”

“…Other studies showed that estrogens may affect the immune system directly or more likely indirectly through several tissues and may modulate the immune system by altering the patterns of cytokines and apoptosis [13] [14]. For example, in O. mykiss, and gilthead seabream, shown that the rise of sex hormones can suppress the plasma IgM and IgM secreting cells during spawning period leading to immunosuppressive condition although the suppressive effects of E 2 on IgM production are not observed in carp and zebra fish (Danio rerio) [15].…”

(2015) AbstractThis study evaluated efficacy of maternal and larval immunisation against Lactococcus garviae infection and on the lysozyme and immunoglobulin (IgM) levels in rainbow trout Oncorhynchus mykiss (Walaum). Forty-eight-day-old larvae (mean weight 96 mg) originating from injected weekly with letrozole and immunised, only immunised and non-immunised parents were experimentally infected with the L. garvieae, and the mortality rate was recorded daily. Larvae were vaccinated by immersion at 58 days post hatch with live L. garvieae (10 9 cells/mL) for 15 min. Every third day post larvae vaccination, two larvae from each group were collected for analysis lysozyme (by a method based on the ability of lysozyme to lyse the bacterium Micrococcus lysodeikticus) and IgM (by enzyme-linked immunosorbent assay (ELISA)) parameters. Vaccinated and control larvae were tested for protection against L. garvieae 30 days post larvae immunization when the larvae were 88 days old. Larvae were challenged by bath exposure with live L. garvieae (10 9 cells/mL) for 2 min and monitored for mortality for at least 10 days following challenge. The challenge experiment with L. garvieae showed a significant reduction in larvae from immunised (54.44% ± 0.64%) and injected weekly with letrozole and immunised fish (52.96% ± 0.97%) compared to larvae from control fish (62.96% ± 2.22%). Vaccinated larvae originated from injected weekly with letrozole and immunised parents showed significantly higher lysozyme activity compared to other fish groups. Vaccinated larvae showed significantly less mortality compared to controls. The rela-* Corresponding author.
