“…All these results strongly indicated that the maturation of adaptive immune system depends more on age than body size in mandarin fish. Although this was contrary with previous popular views, it was supported by researches in sea bass, in which direct comparison of the Ig level between the faster-and slowergrowing fish from the same spawn did not show obvious difference (Breuil et al, 1997;dos Santos et al, 2000). In addition, in this study, no IgM-producing cells appeared before 20 dph suggesting that innate immune mechanisms or maternal immunoglobulin may provide protection against pathogens during the early stage of development in mandarin fish; so do tilapia, Oreochromis mossambicus (Takemura and Takano, 1997).…”

“…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. At hatching time, this level had been reduced by about 100-fold and no maternal IgM had not been detected in 5 DPH larvae of the sea bass (Breuil, Vassiloglou, Pepin, & Romestand, 1997). A similar situation had been demonstrated in tilapia (Mor & Avtalion, 1990) and the Atlantic salmon (Salmo salar) (Olsen & Press, 1997).…”

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.

“…Even if morphologically mature lymphoid cells are present at early stages, fish might not be functionally immunocompetent until later (Tatner, 1996). The appearance of surface Ig + B cells and cytoplasmic Ig + plasma cells might better indicate the functional maturity of the lymphoid system as suggested for salmon, Salmo salar (Ellis, 1977), carp, Cyprinus carpio (van Loon et al, 1981;Koumans van Diepen et al, 1994), skate, Bathyraja aleutica (Kobayashi et al, 1985), rainbow trout, Oncorhynchus mykiss (Razquin et al, 1990;Castillo et al, 1993) and sea bass, Dicentrachus labrax (Breuil et al, 1997). As the responses to most antigens (T dependent antigens) depend on both T and B cell recognition, the ontogeny of these cell types is important.…”
