“…In our current study, in contrast to growth, increased protein content was recorded in shrimp treated with MEL and CYA singly or in combination. These results agree with previous reports regarding red tilapia (Phromkunthong et al 2013(Phromkunthong et al , 2015a and Asian seabass (Phromkunthong et al 2015b), indicating that the protein content in the whole body and in various parts of fish, such as filet or viscera, directly increased in response to dietary MEL?CYA. Therefore, the increased protein content of shrimp whole body in the MEL?CYA treated group may be attributed to the accumulation of nitrogen from these substances.…”

“…10 g kg -1 diet had negative effects on shrimp growth and feed conversion ratio. As previously reported, growth depression is a clinical sign of the toxicity of combined MEL and CYA that has been reported in mice (Lv et al 2013) and in some farmed fish species, such as red tilapia (Phromkunthong et al 2013(Phromkunthong et al , 2015a and Asian sea bass (Phromkunthong et al 2015b). In addition, the combination of MEL and CYA is more toxic than exposure to either chemical separately (Karbiwnyk et al 2010).…”

“…Data on adulteration by CYA alone in shrimp feed is limited. In our previous study, Phromkunthong et al (2015b) reported no significant difference in the growth of Asian seabass between receiving CYA alone and control. That the reported results tend to differ qualitatively suggests that sensitivity to these chemicals strongly depends on the species.…”

This study examined the effects of dietary melamine (MEL) and cyanuric acid (CYA) singly and in combination on growth, nutrient utilization, immunological responses, oxidative stress, and histological changes in Pacific white shrimp. Seven experimental isonitrogenous (35%) and isolipidic (8%) diets were formulated, namely diet 1 (a control diet without MEL and CYA); diets 2-5 (with MEL and CYA at 2.5 ? 2.5, 5 ? 5, 7.5 ? 7.5 and 10 ? 10 g kg -1 diet); diet 6 (with only MEL at 10 g kg -1 diet) and diet 7 (with CYA alone at 10 g kg -1 diet). The shrimp with initial body weight 2.37 ± 0.02 g were fed with these diets for 10 weeks. The results indicate that all the diets with MEL and CYA singly or in combination had adverse effects on growth and nutrient utilization relative to the control diet (p \ 0.05). Total protease and trypsin activities were significantly lowered by all diets containing MEL (p \ 0.05). Haemolymph parameters, including total hemocyte count, phenoloxidase (PO) activity, respiratory burst, and lysozyme activity, were significantly decreased (p \ 0.05) in shrimp receiving MEL alone (10 g kg -1 diet) and at high combination dosages (10 ? 10 g kg -1 diet). Moreover, MEL and CYA induced oxidative stress, damaged hepatopancreas, decreased antioxidant responses, increased lipid peroxidation, and caused abnormality of hepatocytes.

“…Hence, MMCs are useful response (effect) biomarkers of exposure to environmental pollutants (Agius, ; Agius & Roberts, , ; Fishelson, ; Passantino et al, ). Moreover, changes in the MMC characteristics of several cultured fish species as a result of dietary manipulations (Phromkunthong, Nuntapong, Wanlem, & Boonyaratpalin, ), exposure to infectious agents (Yunis‐Aguinaga et al, ; Zhang et al, ) and mere captivity‐induced stress (Evans & Nowak, ) have been documented.…”

The greater amberjack Seriola dumerili is a new aquaculture fish that may display reproductive dysfunctions. During extensive follicular atresia, which is a common reproductive dysfunction in females during vitellogenesis, part of the reabsorbed yolk returns to the liver to be metabolized and recycled. Melanomacrophage centres (MMCs) are aggregates of macrophage‐like cells that play a role in the destruction, detoxification and recycling of endogenous and exogenous materials, and have been associated with systemic stress. Wild and captive‐reared greater amberjack were sampled in the Mediterranean Sea during two different phases of the reproductive cycle. The liver of reproductively dysfunctional captive‐reared females sampled during the spawning season showed a high density of both MMCs and apoptotic cells. A weak liver anti‐cytochrome P450 monooxygenase 1A immunoreactivity was observed, suggesting that the examined fish were not exposed to environmental pollutants. We propose that the observed increase in MMCs and apoptosis in captive‐reared fish was related to the hepatic overload associated to the metabolism of yolk proteins reabsorbed during extensive follicular atresia. Since follicular atresia is a frequent physiological and pathological event in teleosts, we suggest that the reproductive state should be always assessed when MMCs are used as markers of exposure to stress or pollutants.
