“…Sex analysis was performed under a Leica MZ6 stereomicroscope (Leica Microsystems, Milan, Italy) by ablating the second pleopod, which was examined on a freshly prepared slide, under a Leica DMLB optical microscope (Leica Microsystems, Milan, Italy). The presence of an appendix masculina [ 31 ] indicates a male animal [ 23 ]. To validate the transcriptomic results, further analyses performed on the PL 5 consisted of monitoring the expression of genes in males, deriving them from negative controls (Diatom −), and in females, deriving them from treatments with feed containing diatoms (Diatom +).…”

The protandric shrimp Hippolyte inermis is the only known marine invertebrate whose sex determination is strongly influenced by the composition of its food. In H. inermis, a sex reversal is triggered by the ingestion of diatoms of the genus Cocconeis associated with leaves of the seagrass Posidonia oceanica. These diatoms contain compounds that promote programmed cell death (PCD) in H. inermis and also in human cancer cells. Transcriptomic analyses suggested that ferroptosis is the primary trigger of the shrimp’s sex reversal, leading to the rapid destruction of the androgen gland (AG) followed by a chain of apoptotic events transforming the testes into ovaries. Here, we propose a molecular approach to detect the effects of compounds stimulating the PCD. An RNA extraction method, suitable for young shrimp post-larvae (five days after metamorphosis; PL5 stage), was established. In addition, six genes involved in apoptosis, four involved in ferroptosis, and seven involved in the AG switch were mined from the transcriptome, and their expression levels were followed using real-time qPCR in PL5 fed on Cocconeis spp., compared to PL5 fed on a basic control feed. Our molecular approach, which detected early signals of sex reversal, represents a powerful instrument for investigating physiological progression and patterns of PCD in marine invertebrates. It exemplifies the physiological changes that may start a few days after the settlement of post-larvae and determine the life destiny of an individual.

“…Since IAG might be the sexual 'IAG-switch' for its key roles in sex differentiation in decapod crustacean, and the decapods have striking sex plasticity (Levy & Sagi 2020), it is possible to produce the individuals which were genetically male but phenotypic female (neofemale) or genetically female but phenotypic male (neomale) by utilizing IAG. After mating with normal male or female individuals, the neofemale or neomale could produce all-male or all-female progeny (Levy et al 2019;Guerrero-Tortolero & Campos-Ramos 2019). M. rosenbergii was such a successful case .…”

A large number of decapod crustaceans with sexual dimorphism in body size, most of which, are important economic animals. Besides, some of them such as the red swamp crayfish Procambarus clarkii possess strong invasive ability and would damage ecosystem environment. Thereby, monosex culture of decapods would contribute to not only increasing yield and profits, but also reducing the risks of biological invasion. Insulin-like androgenic gland hormone was reported to be a key regulator in sex differentiation. All-male populations in Macrobrachium rosenbergii were successfully produced through insulin-like androgenic gland hormone manipulation. In addition to sex differentiation, insulin-like androgenic gland hormone was reported to be involved in male secondary sex characteristics maintenance, growth, metabolism, morphology change, ovary development and other functions. Considering its important application value for decapods, insulin-like androgenic gland hormone has attracted much attention in recent years. This hormone was reported to have the structure and function similar to androgenic gland hormone of isopods. In this study, the origin of name of androgenic gland hormone and insulin-like androgenic gland hormone was investigated, and the recent research on structure, function, application and molecular regulation mechanism of insulin-like androgenic gland hormone of decapods was reviewed.

“…In shrimp species, polyploidy is efficient technique to produce sterility for genetic protection and skewing sex ratio towards high production of females which female was identified larger than males in all of penaeid shrimp (Sellars et al, 2010). Guerrero‐Tortolero and Campos‐Ramos (2019) identified in most of penaeid shrimp females grow larger than males such as in Pacific white shrimp, L. vannamei , Kuruma prawn, M. japonicus , giant tiger prawn, P. monodon , Chinese shrimp, F. chinensis and also in Indian prawn, P. indicus . The size of the shrimp also determines the price in the market as by culturing monosex species, respectively, will make better profit.…”

The application of biotechnology in marine shrimp especially in penaeid shrimps aquaculture is increasing in demand. Researcher and scientist consents that application of biotechnology helps improve the shrimp quality and consequently increase the aquaculture shrimp productions. The monosex culture becomes one of the focuses nowadays as the techniques can help increasing the aquaculture yield and obviously increases the aquaculture production. The application of triploidy in penaeid shrimp helps to increase the shrimp size, faster the shrimp growth and also recognized as one of the successful techniques for monosex culture as well as induction of polyploidy, gynogenesis and hormones induces. Triploidy technique is also beneficial to be applied in the shrimp aquaculture for the production purposes. This review paper focuses on the triploid induction in penaeid shrimps, the suitable method to be applied, and also the overview of the triploidy induction from others previous study. Hopefully, this review paper can be the benchmark for the application of triploidy technique in shrimp aquaculture industry and help promoting the shrimp aquaculture shrimp productions in the future.
