“…Charniaux-Cotton, along with various colleagues, made pioneering efforts in this field with amphipods and in the caridean shrimp Lysmata seticaudata (Risso, 1816), considered a species with protandric hermaphroditism. Masculinization of females and feminization of males by implantation and extraction of the male androgenic glands, respectively, have shown the important role of these glands in sex determination of amphipods (Charniaux-Cotton, 1965. Similar results, however, have not been obtained in gonochoristic decapods (CharniauxCotton and Payen, 1985).…”

The sexual system of the caridean genus Lysmata has been described until recently as protandric hermaphroditism, in which individuals change sex from male to female with increasing size. However, recent studies by Bauer andHolt (1998) andFiedler (1998) have shown that female-phase individuals of at least two species are outcrossing simultaneous hermaphrodites, a sexual system described here as protandric simultaneous hermaphroditism (PSH). There is considerable variation in the ontogeny of protandric carideans, revealing an underlying flexibility in sex determination and development which has made PSH possible in at least some Lysmata spp. Possible costs and benefits of retention of male reproductive function in female-phase hermaphrodites are proposed. The PSH appears to be unique (to date) within the Decapoda and other Malacostraca to the caridean genus Lysmata and perhaps the related genus Exhippolysmata. It is puzzling that PSH has evolved in a group with such considerable variation in socio-ecological attributes: some Lysmata species are warm temperate, highly aggregated, with unspecialized (facultative) fish-cleaning behavior while others are tropical species, occur at low density in hermaphrodite pairs associated with sea anemones, and are specialized fish cleaners. Description of sexual systems, costs/benefits of PSH, and socioecological attributes of Lysmata, considered in the context of a phylogeny of the group, will be necessary to understand how PSH evolved in Lysmata and why it has not evolved in other groups of protandric carideans.

“…An intersex individual or gynandromorph is defined as an individual (male or female) that develops alterations in primary and/or secondary sexual features, so that it possesses both male and female characters (Goldschmidt 1938, Ladewig et al 2002, Vasquez & López Greco 2007. The alterations in secondary sexual characteristics may result in nonfunctional hermaphroditism, characterized by oogenesis occurring in the testes, as reported in talitrid amphipods, or, conversely, by spermatogenesis taking place in the gonads of females, which has never been observed (Charniaux-Cotton 1975). In contrast, intersexuality may also be part of a functional protandric, protogynic, or simultaneous hermaphroditism (Brook et al 1994, Fiedler 1998, Rudolph 2002.…”

“…This phenomenon seems to occur at all grades of terrestrialization, from typically aquatic species to fully terrestrial species such as members of the Coenobitidae (Gusev & Zabotin 2007). Currently this sexual abnormality has been recorded in 17 species around the world from different genera and families (Hilgendorf 1897, Fize & Serène 1955, Wenner 1972, McLaughlin 1974, Charniaux-Cotton 1975, Lewinsohn 1982, McLaughlin & Lemaitre 1993, Mantelatto & Sousa 2000, Turra & Leite 2000, Turra 2004, 2005, Sant'Anna et al 2006, Fantucci et al 2008, Gusev & Zabotin 2007.…”

“…Malacostracan crustaceans are primarily gonochoristic with sex that is genetically determined (Charniaux-Cotton, 1975). Exceptions are some parasitic and free-living isopods and amphipods whose sex is determined environmentally (Adams et al, 1987;Vogt et al, 2004).…”

-Study of the reproductive strategy of crayfish species is of great importance in the current astacological world. Crayfish are among the largest freshwater invertebrates, and as keystone species, they are able to regulate the structure of the benthic fauna in the freshwaters, demonstrating different ecological strategies and life spans ranging up to 20+ years. In order to bring together the various pieces of information related to this issue, this overview of published scientific reports was conducted. The majority of crayfish species studied show sexual dimorphism, with approximately equal numbers of males and females. However, over some decades numerous observations have been made for a few species that may have different modes of reproduction, such as hermaphroditism or intersex (e.g. Cherax quadricarinatus, Samastacus spinifrons, Parastacus virilastacus and Pacifastacus leniusculus) and parthenogenesis (only Procambarus fallax f. virginalis).A recent study showed a new case of parthenogenesis as apomictic parthenogenesis (only Orconectes limosus). In addition, there are many investigations into the reproduction biology of crayfish, including using eyestalk ablation or androgenic gland ablation under various lab conditions and hybridization under natural conditions (e.g. Astacus astacus X Astacus leptodactylus, Orconectes rusticus X Orconectes propinquus). There are also some chemical factors which could possibly affect the reproduction system of crayfish in the wild.Key-words: crustacea / parthenogenesis / intersex / hybridization Résumé -Différents aspects des stratégies de reproduction des écrevisses : une revue. L'étude de la stratégie de reproduction des espèces d'écrevisses est d'une grande importance dans le monde astacicole actuel. Les écrevisses sont parmi les plus grands invertébrés d'eau douce, et comme des espèces clés, elles sont capables de réguler la structure de la faune benthique dans les eaux douces, présentant différentes stratégies écologiques et des durées de vie allant jusqu'à 20 ans. Afin de réunir les différents éléments d'information relatifs à cette question, une revue des publications scientifiques a été conduite. La majorité des espèces d'écrevisses étudiées montrent un dimorphisme sexuel, avec un nombre approximativement égal de mâles et de femelles. Cependant, depuis quelques décennies, de nombreuses observations ont été faites pour quelques espèces qui peuvent avoir différents modes de reproduction, tels que l'hermaphrodisme ou l'intersexe (par exemple Cherax quadricarinatus, Samastacus spinifrons, Parastacus virilastacus et Pacifastacus leniusculus) et la parthénogenèse (seulement Procambarus fallax f. virginalis). Une étude récente a montré un nouveau cas de parthénogenèse, une parthénogenèse apomictique (seulement Orconectes limosus). En outre, il y a beaucoup de recherches sur la biologie de la reproduction de l'écrevisse, y compris celle de l'ablation du pédoncule oculaire ou ablation de la glande androgène dans diverses conditions de laboratoire et de l'hybridati...
