“…It has been revealed that progesterone could induce ovarian maturation and spawning in Metapenaeus ensis (Yano, 1985), and 17α-hydroxyprogesterone could stimulate vitellogenin synthesis in Penaeus japonicus (Yano, 1987). In this paper, knockdown of PcC1q-like caused significant decrease of progesterone content in the ovary, suggesting that PcC1q-like may be correlated with the synthesis of ovarian progesterone.…”

“…Recently, it has been reported that GnRH plays an important role in the development of ovarium in P. monodon Ngernsoungnern et al, 2008), and serotonin induces ovarian maturation by increasing vitellogenin accumulation in Fenneropenaeus indicus (Santoshi et al, 2009). Similarly, progesteron was also found to influence ovarian development and spawning in Metapenaeus ensis (Yano, 1985), and improve sperm quality in L. vannamei (Alfaro, 1996). Yano and Wyban (1993) stated that HCG stimulates reproduction in shrimps, while Aktaş and Kumlu (2005) found unclear effects of HCG and LHRH-a on the reproduction of P. semisulcatus.…”

This study deals with investigations on how to control off-season maturation and spawning of the Pacific white shrimp Litopenaeus vannamei by using various maturation techniques. For the experiment, the broodstock were separated into five groups (Group 1: Control, Group 2: Serotonin-injected, Group 3: Ablated, Group 4: Temperature-fluctuated, and Group 5: Another ablated groups). Each of the first four groups were stocked into a 2-m diameter round tank at density of 9.44 shrimps per m 2 (2:1, female/male), while Group 5 were stocked into a 3-m diameter tank at density of 5.67 shrimps per m 2(1:1, female/male). The experiment continued for 2 months until maturation in a recirculation system. Each female was tagged and any ripe female carrying a spermatophore was removed to spawn individually in a spawning tank. The first spawnings occurred on 25-28 th days of the experiment in all the groups. The highest female spawning rate (55-90%) and fecundity (79,778-125,015 eggs) were obtained in the eyestalk-ablated groups (P<0.05). Serotonin (Group 2) induced ovarium development in 35% of the females, generating 60,277 eggs per female. Cyclic temperature fluctuation (Group 4) stimulated ovarium maturation in 39% of the females with a mean fecundity of 28,500 eggs per female (P<0.05). Mean egg fertility rates ranged from 63.08% to 96%, and hatching rates from 8.53% to 31%. Spawning, fecundity and hatching rates were found to be different between the two eyestalk-ablated groups (Group 3 and 5), and the reasons were thought to be due to tank size and/or shrimp stocking density. Our broodstock displayed poor reproductive performance with abnormal egg morphology and low egg hatching rates. The stress caused by off-season reproduction and low genetic variation due to past selective breeding programs might have seriously hampered the reproductive performance of our broodstock. The results of this study has demonstrated that, under M editerranean climatic conditions, the broodstock of this non-indigenous shrimp species can be readily matured and spawned out of season in recirculating systems.Keywords: Shrimp, Litopenaeus vannamei, reproduction, maturation, spawning, egg. Pasifik Beyaz Karidesi (Litopenaeus vannamei)'nin Yarı-tropik İklim Koşullarında Mevsim-dışı Olgunlaştırılıp Yumurtlatılması ÖzetBu çalışma, Pasifik beyaz karidesi Litopenaeus vannamei'nin farklı teknikler kullanılarak mevsim-dışı olgunlaştırılması ve yumurtlatılması ile ilgili araştırmaları kapsamaktadır. Deneme için anaçlar, 5 ayrı gruba (1. Grup: Kontrol, 2. Grup: Serotonin enjekte edilenler, 3. Grup: Gözsapı kesilenler, 4. Grup: Sıcak/soğuk dalgalanması uygulananlar ve 5.

“…Assim, tem-se investigado o envolvimento de outros hormônios no processo reprodutivo, a exemplo de um precursor do hormônio juvenil (metil farnesoato), sintetizado no órgão mandibular, e de ecdisteróides produzidos no órgão-Y (Meusy & Payen, 1988). Yano (1985), trabalhando com Metapenaeus ensis, mostrou que a progesterona induz a maturação ovariana e a desova, enquanto Sarojini et al (1995a), utilizando técnicas in vivo e in vitro, mostrou resultados que reforçam a hipótese da ação do hormônio concentrador do pigmento vermelho (HCPV) como um neurotransmissor que estimula a liberação do hormônio estimulador da gônada em Procambarus clarkii.…”

Evaluation of the effect of serotonin (5-HT) and eyestalk monoablation on the induction of ovary maturation in Penaeus Penicillatus (Alcock, 1905)The effects of serotonin and of the monoablation of eyestalk on the induction of gonadal development of Penaeus penicillatus (red tail shrimp) were investigated. Immature females with an average weight of 20 g were selected and ramdonly distributed into four groups of 5 animals as follows: initial control group (IC), sacrificed at the 1 st day of the experiment; parallel control group (CG), injected with 0.05 ml of saline solution; monoablated group (AG), submitted to monoablation at day 0 and injected with 0.05ml of saline immediatelly after the monoablation and on the 5 th day; serotonin group (SG), injected with 0.05 ml of serotonin, dissolved in saline solution, both on day 0 on the 5 th day, in a total dose of 15 µg per gram of animal's weight (7,74 x 10 -7 mol). Animals were sacrificed on day 0 for the initial control group (IC), and on the 5 th , 10 th and 15 th days for the other groups. A fragment from the front lobe of the animal's gonad was fixed in aqueous Bouin and processed with the usual optic microscopy techniques. Analyses consisted of a morphological description of cells and measurements of the diameter of oocytes, which gave evidence to the stimulating role of serotonin and of monoablation on gonad maturation. The statistical analysis (Anova -SNK, P < 0.05) of the diameter values of oocytes showed monoablation to be more effective in inducing ovary maturation than serotonin at the concentration used (7,74 x 10 -7 mol).Key words: Penaeus sp., serotonin, 5-HT, reproduction, ovary maturation. RESUMOO efeito da serotonina e da monoablação do pedúnculo ocular na indução do desenvolvimento gonadal de Penaeus penicillatus (camarão do rabo vermelho) foi investigado. Fêmeas imaturas com peso médio de 20 g foram selecionadas e distribuídas de maneira aleatória em quatro grupos de 5 animais com uma réplica para cada grupo: grupo controle inicial (CI), sacrificado no 1 o dia do experimento; grupo controle paralelo (GC), injetado com 0,05 ml de solução salina; grupo monoablado (GA), submetido à monoablação no dia 0 e injetado com 0,05 ml de solução salina logo após a monoablação e no 5 o dia; grupo serotonina (GS), injetado com 0,05 ml de serotonina dissolvida em solução salina no dia 0 e 5 o dia, numa dose total de 15 µg por grama de peso do animal (7,74 x 10 -7 mol). Os animais do grupo controle inicial (CI) foram sacrificados no dia 0, e no 5 o , 10 o e 15 o dias para os demais grupos, respectivamente. Fragmentos dos lóbulos anteriores das gônadas dos animais foram fixados em Bouin
