“…This increase could be related to stress (Martins et al 2004) due to higher densities and more intense management. The animals in intensive system showed an increase in the number of leukocytes in the hot season, supporting the studies of Morgan et al (2008), De Pedro et al (2005 and Collazos et al (1998). The number of thrombocytes in fish from the semi-intensive ponds was similar to that reported for the hybrid surubim by Mouriño et al (2012) and Silva et al (2012), but in the intensive system, higher values were similar to those reported by Tavares-Dias et al (2009), which showed no seasonal variation, while fish from the semiintensive ponds had more thrombocytes in the hot season.…”

“…In the present study, hematocrit, relative levels of circulating leucocytes and glucose levels remained were significantly different in densities treatments ( Table 3), suggesting that catfish reared at both 500 and 1 500 fish per m 2 were not able to adapt to the increasing stocking densities under the particular culture conditions and during the experimental period described in this study. These results are in not agreement with that reported in other species, such as gilthead seabream (Sparus aurata), rainbow trout and European seabass (Dicentrarchus labrax) [16][17][18]. Furthermore, this hypothesis is supported by the lack of the immunosuppressive state typically observed in chronically stressed fish.…”

Graphical abstract AbstractThe biofloc technology can control water quality under negligible water exchange. The aim of this study was to evaluate the effects of stocking density on production and blood performance of catfish (Clarias gariepinus [Burchell, 1822]). The catfish were reared in biofloc system (heterotrophic bacteria and addition of sugar for a period of 10 wk and used three levels of density i.e. (500, 1 000, and 1 500) fish per m 2 . The production increased with the increasing of stocking density, relative growth rate decreased with the increasing of that. The stocking density of 1 500 fish per m 2 on the biofloc technology can support maximum catfish production, health and proper water quality.

“…Indeed, the investigation of reproductive-immune interactions in fish has demonstrated that sexual maturation is often related to both innate and adaptive immune responses. These interactions affect innate immune proteins (Kumari et al 2006;Bowden et al 2007;Morgan et al 2008), acquired antibodies (Browser and Munson 1986;Steine et al 2001), and the number and proportion of leukocytes (Lamková et al 2007). Temperature and, to a lesser extent, other factors such as photoperiod appear to be the major cues driving these seasonal changes in immune markers (Bowden et al 2007).…”

The effects of estrogenic and androgenic endocrine disruptors on the immune system of fish: a review

2011

During the last decade, a number of studies have shown that, in addition to their classically described reproductive function, estrogens and androgens also regulate the immune system in teleosts. Today, several molecules are known to interfere with the sex-steroid signaling. These chemicals are often referred to as endocrine disrupting contaminants (EDCs). We review the growing evidence that these compounds interfere with the fish immune system. These studies encompass a broad range of approaches from field studies to those at the molecular level. This integrative overview improves our understanding of the various endocrine-disrupting processes triggered by these chemicals. Furthermore, the research also explains why fish that have been exposed to EDCs are more sensitive to pathogens during gametogenesis. In this review, we first discuss the primary actions of sex-steroid-like endocrine disruptors in fish and the specificity of the fish immune system in comparison to mammals. Then, we review the known interactions between the immune system and EDCs and interpret the primary effects of sex steroids (estrogens and androgens) and their related endocrine disruptors on immune modulation. The recent literature suggests that immune parameters may be used as biomarkers of contamination by EDCs. However, caution should be used in the assessment of such immunotoxicity. In particular, more attention should be paid to the specificity of these biomarkers, the external/internal factors influencing the response, and the transduction pathways induced by these molecules in fish. The use of the well-known mammalian models provides a useful guide for future research in fish.
