“…Progesterone plays an important role in the reproductive development of both vertebrates and invertebrates (Fingerman et al 1993;Pinter and Thomas 1997;Lora et al 2005;Meunpol et al 2007;Pfeifer et al 2009). In vertebrates, progesterone regulates both sexual differentiation and reproduction.…”

The existence of progesterone receptors (PR) in the Scylla paramamosain (mud crab) was studied using immunological techniques. By Western blotting, PR with an apparent molecular weight of 70 kDa is identified in both the brain and the thoracic ganglion. By immunohistochemistry, PR immunoreactive neurons are detected mainly in the protocerebrum, the subesophageal ganglion and the leg ganglion. PR immunoreactivity is localized mainly in the nuclei of these neurons, while only a few neurons show such activities in their cytoplasm. Our results provide evidence that progesterone modulates the neuroendocrine system mainly via nucleus receptors.

“…To date, a number of hormones have been identified in polychaetes, for example, osmoregulatory hormones [5], oxytocin/vasopressin hormones [6,7] reproductive hormones [8], sex hormones [9], sex pheromones [10], immunity and inflammation hormones [5,11]. Some hormones of polychaetes, such as progesterone and 17a-hydroxyprogesterone, have been reported to be capable of inducing shrimp oocyte development [12]. Based on our previous finding on high contents of arachidonic acid in whole polychaetes [13], since arachidonic acid is a potent precursor for prostaglandin E 2 , we were interested in investigating whether PGE 2 was also present in these animals and if this hormone from polychaetes can affect shrimp oocyte development in vitro.…”

Prostaglandins are involved in the reproductive processes in a variety of animals, including crustaceans. It was found that polychaetes, the best maturation diet for shrimp broodstock, possessed the greatest variation of prostaglandin E 2 (PGE 2 ) when compared with other live feeds. The level of PGE 2 varied according to sizes, feed intake, sources and type of polychaete. The matured and also larger sand polychaete Perinereis sp. contained higher PGE 2 levels than younger and smaller sand polychaetes (18.16 ± 5.82 ng PGE 2 mg -1 protein for polychaetes at an average length of 10 cm up to 160.8 ± 37.09 ng PGE 2 mg -1 protein for polychaetes at an average length of 17 cm). The PGE 2 levels in ovaries and haemolymph of female shrimp fluctuated with the developmental stage of the ovaries. The highest concentration of PGE 2 in haemolymph was at stage 3 of ovarian development, whereas the highest concentration of PGE 2 in shrimp ovaries was at stage 4. In vitro incubation of Penaeus monodon pre-vitellogenic oocytes with polychaete extract and synthetic PGE 2 demonstrated that both PGE 2 s enhanced oocyte development, especially during late development and ovulation. The putative role of PGE 2 from polychaetes or the presence of PGE 2 in polychaetes may be a factor in their role as a dietary constituent required for shrimp oocyte development.

“…Several polychaetes, including some from this genus (Perinereis) have been shown to contain these and other hormones that stimulate ovarian development in one of the more difficult penaeid species to breed, namely P. monodon (e.g. prostaglandin: Poltana et al, 2005; progesterone, 17a-hydroxyprogesterone: Meunpol et al, 2007Meunpol et al, , 2010methyl farnesoate: Laufer et al, 1997). However, the nutritional value and PUFA profile of polychaetes as well as other diets can vary with species, season of harvest, life stage, habitat, environment, and food chain of each polychaete (Luis and Passos, 1995;Meunpol et al, 2005;Chimsung, 2014).…”

To investigate the effect of different food items on fatty acids profile of Perinereis nuntia worms, Polychaete worms mentioned above were collected from the tidal shores of Bandar Abbas . In this study three treatments included nutritional Commercial post larval shrimp, green algae (Entermorpha. sp.) and red algae (Gracillaria. sp) each with three replications dry was used to feed the worms. Feeding twice daily and 10% of the body weight of worm for two months was conducted. The results showed that different treatments in terms of food fatty acid profile there is a significant difference (P<0.05) . Most fatty acids (SFA) 35.88 ± 0.01, (MUFA) 43.82 ± 0.01 and (PUFA) 108.98 ± 0.01 (mg g -1 ) of polychaete worms were fed red algae. Results suggest that Perinereis nuntia fed red algae have a well-balanced nutritional profile for penaeid shrimp and fish broodstock.
