“…An important factor in determining fecundity is female size (Bauer 1991(Bauer , 2004 which limits the physical space below to the abdomen for incubating embryos. The results of the present study revealed that larger females carry more embryos than smaller ones, thus corroborating fecundity studies in other tropical caridean shrimps (Bauer 1991;Corey & Reid 1991;Anger & Moreira 1998;Pavanelli et al 2008;Hernáez et al 2010;Bertini & Baeza 2014). Compared to other American Processidae, the average fecundity of N. schmitti obtained (432 embryos in Stage I) was higher than that found by Bauer (1991) for Processa riveroi Manning & Chace 1971 (384 embryos), and those reported by Bauer (1991) and Martínez-Mayén and Román-Contreras (2013) for Processa bermudensis (Rankin 1900) (129 and 176 embryos, respectively), species slightly smaller than N. schmitti (see Manning & Chace 1971;Bauer 1991;Bauer & Conner 2012).…”

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.

“…Egg production is an important parameter to be considered in the analysis of this organism's reproductive strategy (Bertini & Baeza, 2014). It can be used to estimate both the stock size and the reproductive potential of a given species or population (Hattori & Pinheiro, 2003).…”

This study tested for social monogamy inAlpheus brasileiroAnker, 2012. We also analysed egg production in this species. Sampling was conducted bimonthly from March 2013 to January 2014, and specimens were collected manually in the intertidal estuarine zone of Cananéia, São Paulo, Brazil. A total of 186 specimens (92 males and 94 females) were captured, and ~46% of them were found living in heterosexual pairs. The carapace length (CL mm) of paired males and females was positively correlated. We analysed 35 females carrying eggs underneath the abdomen: 28 of these females had eggs in stage I of development, four had eggs in stage II, and three had eggs in stage III. The average (±SD) mean fecundity for females carrying early (stage I) eggs was 149 (±93) eggs. Egg volume differed significantly among developmental stages, with a 35.4% increase in egg volume between stages I and III. The egg volume and size (CL) of females correlated positively. A positive correlation between the number of eggs and carapace length was found, with a proportional increase in the number of eggs according to the size of females. Our results suggest that the studied population ofA. brasileirois socially monogamous and provide the first insights into egg production in this species.

“…According to Litulo (2004), internal factors such as biological characteristics of organisms and physical-chemical factors like salinity, temperature, moon cycle and photoperiod may determine reproductive phase periodicity, regulating the reproductive potential and the possible size of the resulting population (Mantelatto & Franzoso, 1997). Preliminary studies on the fecundity of crustaceans showed a positive relationship between fecundity and size of the parental female (Bertini & Baeza, 2014;Hynes, 1954;Ivanova & Vassilenko, 1987;Peixoto et al, 2004). To estimate fecundity in a proper way and not underestimate this value due to loss during incubation, para determinar la correlación entre el número y la talla de los embriones vs. el CL.…”

We studied reproductive characteristics of the phantom shrimp Tozeuma carolinense inhabiting sea-grass beds to test hypotheses about seasonality of reproduction, sex ratio and sexual system, and fecundity values in 3 Mexican collecting sites in the Gulf of Mexico. Four hundred and eighty collected individuals were measured and separated to 3 groups. Based on discriminant analysis, carapace length (CL) was selected as morphometric feature to define 10 size-class intervals. The relationship between sexes were analyzed. Embryos were counted, measured and classified into 4 stages of development. Regression analyses were performed to determine the correlation between the number and size of embryos vs. CL. Sex ratio was 1:1, however, for each location, the sex ratio was different. Males were smaller than females; ovigerous females were larger than non-ovigerous females and males. Fecundity analysis have a significant positive relationship, both in the number and size of embryos vs. female CL. Ovigerous females were found at all dates, and confirmed in El Cayo populations with monthly samples in a year, so that we conclude that T. carolinense belongs to the species category with a seasonal-continuous reproduction.
