“…Re-maturation occurred at AB group found in this experiment showed that the lost of eye stalk caused an inhibiting production of GIH which lead to a continuously maturation process. This phenomenon supported the previous study by Wongprasert et al (2006) who reported that ablated tiger shrimp can mature and spawn three times continously with a trend of decreasing significantly the hatching rate and survival of nauplii.…”

“…This is indicated that hormonal change caused by ablation has different effects on each individual male tiger shrimp. Optic lobe located at eye stalk which was not completely destroyed during ablation was suspected to still produce GIH to some extend so that inhibition of gonadal maturation still occurred (Wongprasert et al, 2006). In contrast, spermatophore maturation in OD0.5 and OD1.0 happened simultaneously and required shorter period within 7 days.…”

“…Ablation is a technique to cut one of the spawner's eye in order to reduce production of gonadal inhitibing hormones. Although ablation can accelerate the process of gonadal development of tiger shrimp, it has several disadvantageous such as stimulating a strong stress even mortality of the spawner, destroying physiological function, decreasing gamet quality, and against to the animal welfare (Wongprasert et al, 2006;Sainz-Hernández et al, 2008;Uawisetwathana et al, 2011). Furthemore, the use of ablated tiger shrimp generally only for 3-4 maturation cycles before being discarded.…”

The aim of this study was to evaluate the effect of oodev on the gonadal maturation and characteristic of spermatophore and spermatozoa produced by the wild male black tiger shrimp against eyestalk ablation. The treatments were two doses of oodev injection at 0.5 (OD0.5) and 1 (OD1.0) mL/kg of body weight and a control was eyestalk ablation (AB). The male stock of tiger shrimp used was from wild with body weight ranged from 55-85 g, stocked into three of 10 tonnages concrete tanks with density of 25 males/tank. Oodev injection was applied for two times with one week interval. Tiger shrimp of OD0.5 group produced the highest number of gonadal maturing which was 84% followed by AB (68%) and OD1.0 (64%). Oodev injection was able to shorten the time required for spermatophore maturation at maturation phase which happened simultaneously within 7 days post injection compared to that of ablated males. Positive correlation (R2=0.612) was detected between the shrimp weight and weight of spermatophore of the tiger shrimp while correlation between spermatophore weight and number of spermatozoa was relatively low (R2=0.415). Total fatty acid tented to be higher in males injected with oodev compared to ablated males. Concentration of arachidonic acid in the muscle of male stock in OD1.0 group was extremely low of 0.0037% of total lipid compared to AB (0.3190%) and OD0.5 (0.2806%). Oodev injection at the dose of 0.5 mL/kg of tiger shrimp could improve the number of males stock producing spermatophore compared to eyestalk ablation. Simultaneously matured-spermatophore of wild male tiger shrimp within short time could be achieved through oodev injection.Keywords: oodev, spermatophore, reproduction, tiger shrimp ABSTRAK Tujuan penelitian ini adalah mengevaluasi efek hormon oodev terhadap pematangan gonad dan karakter spermatofor dan spermatozoa yang dihasilkan oleh induk udang windu jantan alam dibandingkan dengan teknik ablasi tangkai mata. Perlakuan yang dicobakan adalah dua dosis injeksi oodev yaitu 0,5 (OD0,5) dan 1 (OD1,0) mL/kg bobot tubuh dan kontrol yaitu ablasi tangkai mata (AB). Induk udang windu jantan yang digunakan berasal dari alam berbobot antara 55-85 g, ditebar dalam tiga bak pematangan gonad berkapasitas 10 ton dengan kepadatan 25 ekor/ bak. Injeksi oodev dilakukan dua kali dengan interval satu minggu. Induk udang windu pada OD0,5 menghasilkan jumlah induk matang gonad tertinggi yaitu 84%, diikuti oleh AB (68%) dan OD1 (64%). Injeksi oodev mampu mempersingkat masa pematangan spermatofor pada fase maturasi dan pematangan tersebut terjadi secara simultan setelah 7 hari pascainjeksi dibandingkan dengan induk yang di ablasi. Korelasi positif (R2=0,612) dideteksi antara bobot tubuh dan bobot spermatofor induk udang windu, sedangkan korelasi antara bobot spermatofor dan jumlah spermatozoa relatif lemah (R2=0,415). Total asam lemak daging cenderung lebih besar pada induk udang windu jantan yang diinjeksi oodev dibandingkan yang diablasi.

“…However, reduced reproductive performance in aquacultures of black tiger shrimp has caused economic losses and hampered the fishing industry (Wen et al, 2015). In general, unilateral eyestalk ablation is used to induce P. monodon ovarian maturation, but this technique can lead to the death of parent shrimp and lower spawning quality (Benzie, 1998;Wongprasert et al, 2006;Phinyo et al, 2014). Therefore, the examination of alternative approaches is imperative.…”

ABSTRACT. Reduced reproductive performance of the black tiger shrimp (Penaeus monodon) has caused economic losses and hampered the fishing industry. Detailed investigation of the molecular mechanism by which the cell cycle is regulated in this organism is needed to understand the development and maturation of ovaries and oocytes, with a view to improving reproductive capacity. Cell cycle progression is mainly determined by cyclin-dependent kinase (CDK) and cyclin complexes, the cyclin E/CDK2 complex playing a key role in G1/S transition. However, knowledge of the interplay between cyclin E and CDK2 in invertebrates remains limited. In this study, full-length P. monodon cyclin E (Pmcyclin E) and CDK2 (PmCDK2) sequences were cloned. The open reading frame of Pmcyclin E was 1263 bp in 2 C. Zhao et al. Genetics and Molecular Research 15 (3): gmr.15038716 length and encoded a 47.9-kDa protein, while that of PmCDK2 was 921 bp, encoding a protein of 34.9 kDa. Recombinant cyclin E and CDK2 proteins were expressed in Escherichia coli and purified by Ni-chelating affinity chromatography. In addition, a pull-down assay was performed to identify any interaction between Pmcyclin E and PmCDK2. This research provides a basis for the study of the functional mechanisms of the cyclin E/CDK2 complex in shrimp, further enriching our knowledge of invertebrate cell cycle regulation.

“…A similar response was reported by FERREIRA et al (2005) studying A. platensis fed for 15 days on a high-carbohydrate or highprotein diet in controlled laboratory conditions. Several studies have evaluated maturation, eye ablation (SAGI et al, 1997;WONGPRASERT et al, 2006), use of hormones (ABDU et al, 2001), fecundity (KING, 1993), and reproductive cycle (SERRANO-PINTO et al, 2004) of the redclaw crayfish under laboratory conditions.

ABSTRACT. The goal of this study was to evaluate the effect of a high-carbohydrate diet (HC) and a high-protein diet (HP) on the metabolism of the crayfish Parastacus brasiliensis (Von Martens, 1869), collected in different seasons and maintained in the laboratory for 15 days. Crayfish were collected monthly from January 2002 to January 2004 at São Francisco de Paula, Southern Brazil, in Guarapirá stream. In the laboratory, the animals were kept submerged in aquariums under controlled conditions. They were fed ad libitum, for 15 days with either a HC or HP diet. At the end of this period, haemolymph samples were collected, as were hepatopancreas, gills, and abdominal muscle that were removed for determination of glycogen, free glucose, lipids, and triglycerides. The haemolymph samples were used for determination of glucose, proteins, lipids, and triglycerides. Statistical analysis (ANOVA) revealed significant seasonal differences in biochemical composition in crayfish maintained on HC or HP diets. Independent of the diets offered to the animals and the controlled conditions for 15 days, the indications of seasonality were unchanged. The observed changes seemed to be related to the reproductive period. Moreover, the HC diet increased all energy reserves in adult parastacids, which may aid in reproduction. KEYWORDS.Crayfish, experimental culture, diet, metabolism, seasonality. Após o final do período, as amostras de hemolinfa foram coletadas, assim como o hepatopâncreas, as brânquias e o músculo abdominal foram removidos para a determinação do glicogênio, glicose livre, lipídios e triglicerídeos. As amostras de hemolinfa foram usadas para a determinação da glicose, proteínas, lipídios e triglicerídeos. As análises estatísticas (ANOVA) revelaram uma diferença sazonal significativa na composição bioquímica nos lagostins mantidos com dieta HC ou HP. Independente da dieta oferecida para os animais e das condições controladas por 15 dias, não foi possível alterar os perfis metabólicos encontrados sazonalmente nos animais em campo. As mudanças observadas parecem estar relacionadas ao período reprodutivo. Além disso, a dieta HC aumentou todas as reservas energéticas nos parastacídeos adultos, o que pode auxiliar na reprodução. RESUMO. Variações sazonais do efeito de uma dieta rica em carboidrato e rica em proteínas no metabolismo intermediário de PALAVRAS-CHAVE.Lagostim, cultivo experimental, dieta, metabolismo e sazonalidade.
