“…Sin et al [40] reported significant antibody against Ichthtyophinus multifilis in Oreochromis aureus by immunising 1 month prior to spawning and also re- ported successful transfer of antibody from mother to offspring. The successful transfer of immunoglobulin antibody from mother to offspring has also earlier been reported in many fish species including plaice [41], tilapia [42]- [44], red sea bream [45] and sea bream [46]. In the present study, the high levels of circulating antibodies detected against L. garvieae confirmed the immune response of the parents.…”

How to cite this paper: Akbary, P., et al. (2015) AbstractThis study evaluated transfer of maternal lysozyme and immunoglobulin (IgM) against Lactococcus garviea, the causative agent of lactococcosis to eggs and larvae in rainbow trout. Changes in circulating lysozyme and IgM during development of eggs and larvae were measured by a method based on the ability of lysozyme to lyse the bacterium Micrococcus lysodeikticus and enzymelinked immunosorbent assay (ELISA) respectively. For doing this, twelve broodstocks were injected weekly with 2.5 mg•kg −1 letrozole (an endocrine disrupter component) two months before spawning season and vaccinated intraperitoneally (i.p) with a bacterin (inactivated L. garviae) one month before spawning. Twelve broodstocks for vaccination and twelve female rainbow trouts as control group were also immiunised (i.p) with the bacterin and injected (i.p) with PBS respectively. Results showed that at day 8 after hatching, lysozyme and IgM levels during pre-larval stages decreased gradually, as yolks were absorbed. Lysozyme and IgM levels were significantly higher in the letrozole injected immiunised parents 30 days after immunisation as well as their larvae compared to the control group (p < 0.05). These results showed the lysozyme and IgM detected from day 0 to day 8 derived from maternal fish while the lysozyme and IgM detected from day 10 onward are neo-synthesized lysozyme and IgM. The present study indicated the role of the injection of letrozole (two months before spawning) and parent immunisation with a bacterin (inactivated L. garviae) (one month before spawning) in maternal transfer of lysozyme and IgM levels to eggs and larvae. *Corresponding author.

“…A similar situation had been demonstrated in tilapia (Mor & Avtalion, 1990) and the Atlantic salmon (Salmo salar) (Olsen & Press, 1997). Pre-larval stages of the tilapia (0 to 12 DPH) showed relatively high maternal value of the IgM level, which gradually decreased to a minimum level at 12 DPH just prior to the development of the larval lymphoid organs and the autologous IgM production (Takemura, 1993). In the salmon, the maternal IgM level was abruptly decreased after hatching, reaching minimum levels just prior to the onset of feeding and the autologous IgM production (Olsen & Press, 1997).…”

“…It had been shown that the lysozyme in the unfertilized eggs had higher level than the fertilized eggs (1 HPF) and 6 DPH larvae (Cecchini, Terova, Caricato, & Saroglia, 2000). A similar reduction in the lysozyme level was observed in the tilapia larvae after absorbing the yolk sac and starting first feeding (Takemura, 1993). In the Persian sturgeon (Acipenser persicus) and the Sterlet (A. ruthenus), the lysozyme activity was decreased significantly from the unfertilized eggs to the 10 DPH larvae, which it may be because of complete absorption of the yolk proteins by the embryo and larvae.…”

“…The maternal transfer of the IgM to the embryo has been demonstrated in several species such as plaice (Bly, Grimm, & Morris, 1986), tilapia (Takemura & Takano, 1997) and red sea bream (Kanlis et al, 1995). In sea bass (Dicentrarchus labrax), for example, the maternal IgM had been deposited in the ovary during vitellogenesis and reached a maximum concentration during ovulation.…”

In this study, some important immune parameters in the unfertilized and fertilized eggs, larvae of 10 days post hatching (DPH), juveniles of 1 to 12 month post fertilization (MPF) and the female broodstock were evaluated. In the Persian sturgeon, there was a significant decrement in the lysozyme activity from the unfertilized eggs to the 10 DPH larvae and after that, the remarkable variations were not observed. The C3 concentration did not show any significant variations from the unfertilized eggs to the 1 MPF and after that, it significantly decreased. Apart from the fertilized eggs, the variations of the IgM level were similar to the C3 level in the early life stages of the Persian sturgeon. In the Sterlet, the lysozyme level was decreased significantly from the unfertilized eggs to 10 DPH larvae, then it was increased in 1 MPF and finally, a significant difference was not observed from 2 to 12 MPF. The variations of both the IgM and the C3 levels were similar from the fertilized eggs to 12 MPF. In conclusion, the considerable fluctuations of the immune parameters were observed in early life stages especially under 1 MPF which indicates immunologically sensitivity of the fish in these stages.

“…(1) body length was a better continuous variable than Plasma IgM may drop in females coincident with age, and (2) among actively spawning fish, gonad spawning due to incorporation of IgM into the eggs weight (comprising up to 30% of body weight in pres- (Castillo et al 1993, Takemura & Takano 1997; howpawning fish) was highly variable because some fish ever, this incorporation is likely to occur at the level of had spawned and thus had empty gonads while others nanograms of IgM per gram of egg (Takemura & were yet to spawn and still had full gonads.…”
