“…Diverse biogenic amines that are produced in the eyestalks may affect metabolism and osmoregulation in a way that can be or not dependant on CHH action (Liu et al, 2008;Lorenzon et al, 2005). Moreover, according to experiments in Penaeus monodon, other eyestalk peptides, like the red concentrating hormone, can elicit changes in NKA activity in gills, suggesting that it may exert an overlapping endocrine function to CHHs in osmoregulation (Sathapondecha et al 2014). Eyestalk ablation is used to eliminate the primary source of neuropeptides in crustaceans to test their individual effects.…”

Dose-dependent effect of recombinant CHH-B1 on osmoregulatory capacity and Na+/K+-ATPase expression in bilaterally eyestalk-ablated shrimp Litopenaeus vannamei

Osmoregulation in crustaceans is under neuroendocrine control by the crustacean hyperglycemic hormones (CHHs), which modify water and ion concentrations in diverse species. Previous studies done by our group suggested that CHH variant B1 (CHH-B1) has effects on the osmoregulatory responses of the Pacific white shrimp Litopenaeus vannamei. For a better understanding of the molecular action mechanisms of CHH-B1 in osmoregulation, in this work, we established the dose-dependent effect of recombinant CHH-B1 on the gene expression of Na+/K+-ATPase (NKA) in gills, in contrast to changes in the osmoregulatory capacity (OC) of bilaterally eyestalk-ablated shrimp under hyper-osmotic conditions. The results indicate that CHH-B1 regulates the OC of shrimp during hypo-regulation by modulating Na+/K+-ATPase at a transcriptional level. Our results suggest that CHH has a direct participation in the control of osmo-ionic regulation mechanisms, not only in L. vannamei but in crustaceans in general.

“…The structural similarity among RPCH, adipokinetic hormone (AKH), corazonin (Crz), adipokinetic hormone/corazonin-related peptide (ACP) and gonadotropin-releasing hormone (GnRH) in various animals resulted in clustering them together into the GnRH-superfamily ( 91 ). In decapod crustaceans, RPCH is synthesized in the XO/SG complex of the eyestalks, but is also expressed in all major parts of the nervous system, where it is suggested to act as a neurotransmitter having dual endocrine and autocrine/paracrine function ( 66 , 92 , 93 ).…”

“…Increased glucose levels could be elicited in the hemolymph of the isopod Porcellio scaber injected with synthetic RPCH, suggesting a novel role for this neuropeptide in carbohydrate mobilization by causing the release of crustacean hyperglycemic hormone (CHH) ( 102 ). Sathapondecha et al ( 92 ) reported that the expression of RPCH was transiently stimulated upon hypersalinity change within 12 h in P. monodon , suggesting its osmoregulatory functioning. Furthermore, the study also revealed that injection of RPCH peptide increased gill Na + /K + ATPase activity in 36–48 h after injection.…”

Insights on Molecular Mechanisms of Ovarian Development in Decapod Crustacea: Focus on Vitellogenesis-Stimulating Factors and Pathways

Vitellogenesis in crustaceans is an energy-consuming process. Though the underlying mechanisms of ovarian maturation in decapod Crustacea are still unclear, evidence indicates the process to be regulated by antagonistically-acting inhibitory and stimulating factors specifically originating from X-organ/sinus gland (XO/SG) complex. Among the reported neuromediators, neuropeptides belonging to the crustacean hyperglycemic hormone (CHH)-family have been studied extensively. The structure and dynamics of inhibitory action of vitellogenesis-inhibiting hormone (VIH) on vitellogenesis have been demonstrated in several species. Similarly, the stimulatory effects of other neuropeptides of the CHH-family on crustacean vitellogenesis have also been validated. Advancement in transcriptomic sequencing and comparative genome analysis has led to the discovery of a large number of neuromediators, peptides, and putative peptide receptors having pleiotropic and novel functions in decapod reproduction. Furthermore, differing research strategies have indicated that neurotransmitters and steroid hormones play an integrative role by stimulating neuropeptide secretion, thus demonstrating the complex intertwining of regulatory factors in reproduction. However, the molecular mechanisms by which the combinatorial effect of eyestalk hormones, neuromediators and other factors coordinate to regulate ovarian maturation remain elusive. These multifunctional substances are speculated to control ovarian maturation possibly via the autocrine/paracrine pathway by acting directly on the gonads or by indirectly exerting their stimulatory effects by triggering the release of a putative gonad stimulating factor from the thoracic ganglion. Acting through receptors, they possibly affect levels of cyclic nucleotides (cAMP and cGMP) and Ca 2+ in target tissues leading to the regulation of vitellogenesis. The “stimulatory paradox” effect of eyestalk ablation on ovarian maturation continues to be exploited in commercial aquaculture operations, and is outweighed by the detrimental physiological effects of this procedure. In this regard, the development of efficient alternatives to eyestalk ablation based on scientific knowledge is a necessity. In this article, we focus principally on the signaling pathways of positive neuromediators and other factors regulating crustacean reproduction, providing an overview of their proposed receptor-mediated stimulatory mechanisms, intracellular signaling, and probable interaction with other hormonal signals. Finally, we provide insight into future research directions on crustacean reproduction as well as potential applications of such research to aquaculture technology development.

“…The color changes are under control of eyestalk hormones, they are rapid, reversible and rhythmic [13,14] [17,21], due to increased consumer acceptance, improved product quality and price paid for commercial shrimp species [22,23], with dark red colored shrimp attracting premium prices.…”

“…This color may be in the exoskeleton or structures in pigments within the underlying hypodermic layer known as chromatophores [13]. The amount and distribution of pigment are dependent of dietary, environmental and genetic factors [14]. The main purpose of this study was to review the importance of color in the marine shrimps that are cultivated in ponds in the world.…”

In the present review, we have described aspects of the color of marine shrimp of importance in aquaculture (mainly Penaeus japonicus, Litopenaeus vannamei and Penaeus monodon) and in the world. It is generally described some ecological aspects and some factors that affect the color of the shrimp. It describes in a general way, ecological aspects and some factors that affect the color of the shrimp, as well as, specifi c aspects like the color change, the importance of the pigments in the color and the effect of the cooking and storage processes on the color of the shrimp. As well as some strategies that have been used to improve the color during the last decades are discussed. As well as the ability to select genetic lines of color shrimp.
