“…www.nature.com/scientificreports www.nature.com/scientificreports/ requirements for shrimp reproduction are poorly defined, live feeds such as polychaetes, squid, and mussels are generally used to prepare broodstock before mating because they are nutritionally rich in proteins, lipids, polyunsaturated fatty acids (PUFA) 3,4 , and sex steroid hormones, such as progesterone and its derivatives 5 . Dietary PUFAs have been reported to benefit ovarian development in several crustacean species, such as the Pacific white shrimp Litopenaeus vannamei 6 , the Chinese mitten crab Eriocheir sinensis 7 , the mud crab Scylla serrata 8 and P. monodon 9 .…”

Unilateral eyestalk ablation in the female black tiger shrimp Penaeus monodon is commonly employed to induce ovarian maturation. However, the importance of complementing this practice with the provision of live feed supplement (such as polychaetes) has not been emphasized in previous studies. Indeed, it has been less emphasized that female broodstock must be fed with live feeds such as polychaetes for this practice to be effective. While the effects of eyestalk ablation have been thoroughly studied in various aspects, the synergistic effects of feeding with live feeds and the ablation have never been elucidated at a transcriptome-wide level. With recent advances in the next-generation sequencing platforms, it is now possible to investigate the effects of eyestalk ablation and live feeds at the transcriptomic levels. This study employed both short-read Illumina RNA sequencing and long-read Pacific Biosciences (PacBio) isoform sequencing (Iso-seq) to generate the first high-quality ovarian reference transcriptome in P. monodon. This novel assembly allowed us to dissect the effects of feeds and eyestalk ablation and reveal their synergistic effects at the transcriptomic level through the regulation of important genes involved in fatty acid regulation, energy production, and hormonemediated oocyte maturation pathways. The synergistic effects between the polychaete feeding and the eyestalk ablation in the process of ovarian maturation in black tiger shrimp suggest that without having proper nutrients from the polychaetes, female broodstock might not be ready to develop its ovary. However, even with proper nutrients, the eyestalk ablation is still necessary to perhaps manipulate the female endocrine of the black tiger shrimp. These findings shed the light on molecular mechanisms and key molecular pathways that lead to successful ovarian maturation. The black tiger shrimp (Penaeus monodon) is the second most widely cultured shrimp species in the world (FAO 2016). Albeit high demand worldwide, the shrimp production level remains stagnant mainly due to the outbreak of diseases and lack of selective breeding programs. The future success of the shrimp industry will depend upon increasing supplies of healthy, high-quality seed for stocking ponds and decreasing reliance on wild broodstock, which might potentially be a disease carrier and have seasonal variation 1. To overcome these challenges, it is vital to be able to enhance reproductive maturation of captive broodstock. Ovarian maturation is a well-orchestrated and complex molecular process that requires the regulation of large sets of genes to ensure proper oocyte development for embryogenesis. In penaeid shrimp, the process can be categorized into four stages: (I) previtellogenesis, (II) vitellogenesis, (III) early cortical rod, and (IV) late cortical rod 2. Numerous factors and methods have been investigated to improve reproductive maturation in female black tiger shrimp. Dietary choices have been shown to be important for the maturation.

“…Similarly, it was found by Meunpol et al (2005) who concluded that no relationship between spermatophore weight and number of spermatozoa cell or correlation between these two variables was low (Jiang et al, 2009). The low R 2 value also impiled that there is an independent variable influenced the number of spermatozoa such as nutrition (Braga et al, 2013;Leelatanawit et al, 2014). In addition, weight of spermatophore is not only afftected by the sperm cell mass but only by the intermediated acellular secreted by vas deferens (Diwan & Josep, 2009).…”

“…Based on morphological observation on spermatozoa cell, it was also identified undeveloped spikespermatozoa inside spermatophore. Leelatanawit et al (2014) stated that spermatozoa of tiger shrimp has still developed in vas deferens before reaching spermatophore. Based on histological observation it showed that oodev stimulation did not negatively affect the anatomy of reproductive organ of male tiger shrimp.…”

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.

“…Polychaete worms (Annelida: Polychaeta) comprise a major fraction of prey for many secondary consumers in marine ecosystems and can satisfy the nutritional demand of predators (Olive, 1999), including mud crabs. Previous research has shown how polychaetes used as live feed can enhance the maturation (Binh et al, 2008) and reproductivity of crustaceans (Leelatanawit et al, 2014). Polychaetes are potentially suitable as sustainable feed because they also consume and convert low‐value microscopic organic matter into higher quality concentrated food source for crustaceans and other aquatic animals (Brown et al, 2011; Mandario et al, 2019).…”

The potential use of polychaetes as feed for mud crabs and to bioremediate highly underexploited nutrient‐rich aquaculture waste was evaluated in this study. Food preference of mud crabs (Scylla olivacea) given two polychaete species, namely Namalycastis sp. (Nereididae) and Eunice reticulata, was first determined prior to elucidating the growth, survivorship and fatty acid composition of the selected polychaetes cultivated using fish culture waste (FCW). The effect of water temperature on the sexual maturation of selected polychaetes was also evaluated. Mud crabs fed on both polychaete species but a preference for Namalycastis was observed. Namalycastis fed FCW experienced lower survivorship (16.7%–58.3%) than those in control treatments of either fish feed or no feed (41.7%–100%), although statistically there were no significant differences between treatments for all three experiments. This could probably be due to mortality of FCW‐grown Namalycastis after spawning. FCW‐grown Namalycastis had significantly higher (p < .05) wet length than unfed polychaetes. Sexual maturation in Namalycastis was not affected by lowering ambient temperature from 28°C to 26°C. Compositions of arachidonic acid, eicosapentaenoic acid and docosahexaenoic acid were higher in FCW‐grown Namalycastis than unfed Namalycastis. Overall, Namalycastis can be cultured in captivity using FCW but further research is required to mass produce the polychaetes economically and sustainably.
