“…The morphological, histological and biochemical parameters used for assessing ovarian maturity clearly indicated that 5-HT had a stimulatory effect while DA had the opposing effect. The 5-HT induced and DA inhibited gonadal maturation have been reported in a number of decapods (Richardson et al, 1991;Sarojini et al, 1995a;Vaca & Alfaro, 2000;Chen et al, 2003;Alfaro et al, 2004;Wongprasert et al, 2006;Santhoshi et al, 2009;Tinikul et al, 2009;Sainath & Reddy, 2011;Tropea & Lopez Greco, 2013;Aprajita et al, 2014;Prasad et al, 2014).…”

“…Furthermore, in M. rosenbergii, 5-HT-treated group exhibited significantly greater OI and mean OD values with more number of vitellogenic and mature oocytes (Meeratana et al, 2006) and accelerated vitellogenin synthesis (Kuo et al, 2009) whereas the DA-treated group displayed diminished vitellogenin synthesis (Chen et al, 2003). It was reported that in Cherax quadricarinatus, DA treatment effected decreased OI values with a higher percentage of underdeveloped ovaries (Tropea & Lopez Greco, 2013). In M. rosenbergii, Reddy et al (2013) observed that 5-HT administration boosted the total lipid and triglyceride contents of the ovary and hepatopancreas while contradictory results were obtained with DA.…”

The current study explicated the effects of serotonin (5-hydroxytryptamine, 5-HT) and dopamine (DA) on ovarian development in the edible freshwater crab Travancoriana schirnerae, distributed in the wetlands of Wayanad. Adult intermoult female crabs in various oogenic stages were administered with 5-HT and DA, weekly once for four weeks and the ovaries processed for histological and biochemical analyses. The results indicated that 5-HT induced ovarian maturation by a significant rise in ovarian index, mean oocyte diameter, oocyte proportion values, gonial proliferation, folliculogenesis and degree of yolk deposition while DA showed a significant decline in the aforesaid parameters thus delaying ovarian growth when compared to the untreated controls. Further biochemical analyses confirmed the 5-HT triggered ovarian growth as evinced from the significant rise in total protein, oligo and polysaccharide fractions, free amino acids, lipid and cholesterol contents compared to the significantly low values of DA-treated group and control crabs. The present study clearly demonstrated the antagonistic effects of 5-HT and DA on ovarian maturation in T. schirnerae. In conclusion, the stimulatory neurotransmitter, 5-HT provides a non-surgical practical solution for inducing ovarian growth and maturation in species of aquaculture importance.

“…The primary (or pre-vitellogenic) oocytes were identified by a homogeneous and acidophilic cytoplasm surrounded by round basophilic follicular cells. In contrast, secondary oocytes had an eosinophilic cytoplasm containing yolk droplets and globules, and were surrounded by flat and pyknotic follicular cells [34].…”

Sexual system, reproductive cycle and embryonic development of the red-striped shrimp Lysmata vittata, an invader in the western Atlantic Ocean

Several decapod crustaceans are invaders, but little is known about the biological characteristics that potentiate the success of these decapods in invaded ecosystems. Here, we evaluate and describe some aspects of the reproductive biology and development of Lysmata vittata, an invasive shrimp species in the Atlantic Ocean. In addition, we intend to provide important insights into the biology of invasion by comparing the reproductive traits of this shrimp with some of the predictions about aquatic invasive species. We used experimental and laboratory observations to evaluate the functionality of protandric simultaneous hermaphroditism (PSH), the macro and microscopic development of the ovarian portion of the ovotestes, the reproductive cycle, and the embryonic development of L. vittata. We confirm the functionality of PSH in L. vittata. This shrimp has a rapid reproductive cycle; the ovarian portion of the ovotestes develops (mean ± SD) 6.28 ± 1.61 days after spawning. Embryonic development also occurs over a short time, with a mean (± SD) of 8.37 ± 0.85 days. The larvae hatch without macroscopically visible yolk reserves. Our study provides evidence that the invasive shrimp L. vittata has reproductive and embryonic developmental characteristics (i.e., short generation time and high reproductive capacity) that may be favorable to the establishment of populations during invasive processes.

Distribution and dynamic expression of serotonin and dopamine in the nervous system and ovary of Holothuria scabra during ovarian maturation

et al. 2018

In the present study, the distribution and dynamic expression of serotonin and dopamine in the nervous system and ovary of the sea cucumber, Holothuria scabra, during different ovarian stages were investigated. We found that serotonin-immunoreactivity was more intense in the neurons and neuropils of the outer ectoneural part, the inner hyponeural part, and the wall of hyponeural canal of radial nerve cord during the mature stages of ovarian cycle, whereas dopamine-immunoreactivity was detected at a higher intensity in these tissues during the early stages. Both neurotransmitters were detected in the ectoneural part of the nerve ring. In the ovary, serotonin intensity was more intense in the cytoplasm of late oocytes, while dopamine-immunoreactivity was more intense in the early stages. The changes in the levels serotonin in the radial nerve cord and oocytes are incremental towards the late stages of ovarian maturation. In contrast, dopamine levels in the nervous tissues and oocytes were more intense in early stages and became decremental towards the late stages. These findings suggest that serotonin and dopamine may have opposing effects on ovarian development in this sea cucumber species.
