“…Data of embryo length of N. schmitti are similar those reported by Manning and Chace (1971) for the same species (Table 3), so it is likely that females could invest a similar amount of energy in the production of embryos, though the embryo size also might be genetically determined (Lara & Wehrtmann 2009;Martínez-Mayén & Román-Contreras 2014).…”

“…The high loss of embryos during the latter phases of development also has been reported for other decapod crustaceans: Petrolisthes laevigatus (Guérin 1835) (see Lardies & Wehrtmann 1996) This feature might be related to the larger size of late-stage embryos make them vulnerable to wear and tear of their attachment structures and more liable to be detached from female pleopods (Oh & Hartnoll 1999;Martínez-Mayén & Román-Contreras 2014). In crustaceans, the brood loss during embryogenesis is a common feature that reduces their reproductive potential (Oh & Hartnoll 1999) and is caused by a variety of physical and biological factors (see Kuris 1991).…”

Nikoides schmitti is widely distributed along the Atlantic coast of the Americas, from North Carolina to Bahia, Brazil and Cuba and Guadeloupe; however, the knowledge about their reproductive biology is poorly known. In this study, data such as sex ratio, fecundity, size and volume of the embryos, and brood loss of material collected in July 1997 from Mahahual, Quintana Roo, Mexico is provided. The sample of 728 specimens had a sex ratio of 0.40 males per female. Fecundity (N = 31) of ovigerous females (Stage I) varied from 219 to 817, with an average of 432 ± 177 embryos. The newly extruded embryos of N. schmitti were small (0.41 ± 0.030 mm) and similar in size to those reported for other species of the genus. The mean volume of the embryos changed significantly during development, increasing 60.9% from stages I to III. Embryo loss during incubation was estimated in 32.9%. This study provides baseline information about the reproduction of N. schmitti and contributes to a better knowledge of this species little studied.

“…The mean embryos volume was similar to that in a population of P. northropi studied by Corey & Reid (1991) [44] and to other species of Palaemon, such as P. gravieri [12] and P. longirostris [2] ( Table 1). On the other hand, the embryo volume was higher compared to other Paleomonidae shrimp, such as Cuapetes americanus (Kingsley, 1878) [62] and shrimp of the genus Periclimenes (Costa, 1844) [44,49,57,63]. Differences in embryo volume may be related to differences in the environmental conditions, particularly salinity, of the species' habitats [64].…”

The objective of this study was to evaluate aspects of the reproductive biology of Palaemon northropi, a shrimp of the northeastern Brazilian estuarine region. The specimens were sampled between July and November 2017, with a hand net, and were identified to species level and sexed. We measured the carapace length (CL) of males and females and the second pleura length (PL) of females. A total of 85 individuals were collected, including 36 males and 49 females (24 non-ovigerous and 25 ovigerous). The sex ratio was 0.42, with a non-significant departure from the 1:1 ratio. Mean sizes (±SD) of males and females were 3.41±0.54 and 4.98±1.33 mm CL, respectively. The mean size of the PL (±SD) of females was 2.67±1.03 mm CL. Mean fecundity was 255±57.84 embryos. The CL was positively associated with fecundity, but the fecundity did not vary between embryo developmental stages. Palaemon northropi shows sexual dimorphism, with females being larger than males. The results indicate that the embryonic development of P. northropi occurs normally, even in an estuarine region, such as that of present study, since there was no significant loss of embryos during development. This study contributes to knowledge of the reproductive biology of P. northropi and help in our understanding of the ecological relevance of these shrimps in estuarine environments.

Periclimenes paivai is notable for its symbiotic lifestyle with jellyfish. The objective of this study was to investigate the fecundity and reproductive output of females, and specifically to determine whether females protected in their host have a greater reproductive success than other shrimp species. All anatomical parts of the medusae were analyzed and the P. paivai individuals were separated. Among 83 females analyzed, 65 presented embryos in the first developmental stage, and 18 were in the final stage of development. The mean fecundity was 229.08 ± 120.04 in initial-stage embryos and 191 ± 114.76 in final-stage embryos. We observed a positive relationship between the embryo number and the female size; however, the embryo number was not related to the embryonic stage, which indicates that females did not lose their embryos during the incubation period. The weight of brood mass during production is closely related to the female weight according to the results of linear regression, as fecundity increased with female size. In its symbiosis, P. paivai can increase the amount of energy used to produce embryos (mean reproductive output = 10.38%) and can elevate the reproductive success.
