“…The study of Sagi & Cohen (1990), albeit on only two crosses of sex-reversed M. rosenbergii males (neofemales) with normal males, agreed with the model suggested by Malecha et al (1992). Benzie et al (2001) obtained a significantly skewed sex ratio in favor of males in hybrid juveniles from crosses between two closely related species of shrimp (Penaeidea), possibly suggesting that females are the heterogametic sex in penaeids. In their preliminary study, Austin & Meewan (1999) performed group crosses between two subpopulations of the Australian freshwater crayfish Cherax destructor but could not identify the mechanism of sex determination in that species.…”

“…Indirect information about sexdetermination mechanisms can be deduced from secondary and tertiary sex ratios in decapods, but such data are available only for a few macruran species. Studies providing this type of information usually involve controlled breeding and crossing of parents, which might be sexually inverted in some cases, followed by sexing of the F 1 progeny (Sagi & Cohen, 1990;Malecha et al, 1992 ;Austin & Meewan, 1999;Lawrence et al, 2000 ;Benzie et al, 2001). Most of the researchers performing the above-mentioned studies have suggested a WZ-ZZ scheme, with the female being the heterogametic sex.…”

Sex determination in crayfish: are intersex Cherax quadricarinatus (Decapoda, Parastacidae) genetically females?

et al. 2003

In the Australian red-claw crayfish Cherax quadricarinatus (von Martens) (Decapoda, Parastacidae), a gonochoristic species, seven different combinations of intersex individuals (with both male and female genital openings) have been described. However, to date, the genetic basis for this phenomenon has not been investigated. This study was designed to test a simple chromosome-based sex-determination model for C. quadricarinatus that assumes the male to be the homogametic (ZZ) sex. According to our model, intersex individuals that are functionally males are genetically females (WZ). Individual crosses were performed between intersex and female crayfish, with control crosses being performed between normal males and females. The control crosses yielded, in most cases, the expected 1:1 sex ratio in the F1 progeny. Crosses between intersex individuals and females yielded a 1:3 (male:female) sex ratio in most crosses. According to our hypothesis, one-third of the females produced in a cross of a female with an intersex animal should be WW females. The hypothesis was tested by crossing normal males with F1 females, which were progeny of intersex fathers. These crosses yielded almost 100% females, a finding that conforms to the above-suggested sex determination model for C. quadricarinatus and the female WZ genotype of intersex individuals.

“…To establish mono-sex production in P. monodon, knowledge of the genetic sex-determining mechanism needs to be well understood. Interspecies crosses between P. monodon and P. esculentis suggested that the female sex is most likely to be heterogametic (Benzie et al 2001), and the mapping of phenotypic sex to a linkage group on the female map in P. japonicus (Li et al 2003) and in P. vannamei (Zhang et al 2006) was also consistent with this suggestion. However, none of the markers reported in these studies was completely linked to the sex locus.…”

“…In the case of sex determination, circumstantial evidence on interspecies hybrids between P. monodon and P. esculentus indicates that the female is the heterogametic sex, as the sex ratio of the surviving progeny was skewed to males (Benzie et al 2001). According to Haldane's rule, a higher mortality in such crosses is experienced by the heterogametic sex.…”

High-Density Linkage Maps and Sex-Linked Markers for the Black Tiger Shrimp (Penaeus monodon)

et al. 2008

We report on the construction of sex-specific high-density linkage maps and identification of sex-linked markers for the black tiger shrimp (Penaeus monodon). Overall, we identified 44 male and 43 female linkage groups (2n ¼ 88) from the analysis of 2306 AFLP markers segregating in three full-sib families, covering 2378 and 2362 cM, respectively. Twenty-one putatively homologous linkage groups, including the sex-linkage groups, were identified between the female and male linkage maps. Six sex-linked AFLP marker alleles were inherited from female parents in the three families, suggesting that the P. monodon adopts a WZ-ZZ sex-determining system. Two sex-linked AFLP markers, one of which we converted into an allele-specific assay, confirmed their association with sex in a panel of 52 genetically unrelated animals.

“…Interspecific hybridization in aquatic animals has mainly focused on fish (Scribner, Page & Bartron ), crustaceans (Benzie, Kenway & Ballment ), echinoderms (Rahmana, Uehara & Lawrence ; Ding, Chang, Wang & Cao ) and mollusks (Gaffney & Allen ; Piferrer, Beaumont, Falguière, Flajšhans, Haffraye & Colombof ; Huang, Bi, Hu, Sun, Lu & Bao ; Zheng, Xu & Zhang ; Hu, Huang, Mao, Wang & Bao ) and numerous attempts using a variety of species of oyster have been reported (Gaffney & Allen ; Piferrer et al . ).…”

Phenotypic trait ofCrassostrea hongkongensis♀×C. angulata♂ hybrids in southern China

The Hong Kong oyster (Crassostrea hongkongensis) and the Portuguese oyster (Crassostrea angulata) are important aquaculture species in southern China. To understand the potential feasibility of hybridization between the two species, two-bytwo factorial cross-experiments were conducted in Shenzhen (Guangdong province). An asymmetry in fertilization was revealed: C. hongkongensis eggs could be fertilized by C. angulata sperm, but the reciprocal cross was not possible. The fertilization and hatching success in the C. hongkongensis females 9 C. angulata males (HA) cross was lower than the two intraspecific crosses. Moreover, hybrid larvae had a slower growth rate than those from parental progenies due to genome incompatibility. However, the size of the spat and adult growth were greater than those of the two parental progeny, with obvious heterosis during the grow-out stage. The survival advantage of hybrids was examined at all times. The surprising finding was that all hybrids were completely fertile, meaning they could produce normal and functional gametes. Genetic analysis by molecular markers was applied to confirm that the HA spat were true hybrids. Our results revealed that the interspecific hybridization between C. hongkongensis and C. angulata is completely successful in one direction. Furthermore, hybrids are viable, fast growing and completely fertile, which provides a promising method for the genetic improvement of oysters as a new aquaculture stock in southern China.
