This identification was performed by multiplex PCR of oysters of the genus Crassostrea
, described by MELO et al.
The genus Crassostrea
is well established and contains many well-known species of ecological and economical significance.
However, given the diversity of the genus Crassostrea
, there are several species that are native to different places and with a certain degree of fishery production, aquaculture development or catch for local consumption.
However, in 1897 a recent change occurred when the species was specified in the genus Crassostrea
sacco, and given the name Crassostrea gigantissima.
It is known that water temperature influences the process of maturation and release of gametes, as observed in native oysters of the genus Crassostrea
(Absher, 1989; Christo and Absher, 2006) and Pteria hirundo (Salvador et al., 2011); Anomalocardia brasiliana cockle (Boehs et al., 2008; Luz and Boehs, 2011); Nodipecten nodosus scallop (Albuquerque and Ferreira, 2006; Rupp and Parsons, 2004); Perna perna mussel (Ferreira and Magalhaes, 2004); Tagelus plebeius (Ceuta and Boehs, 2012) and Crassostrea gigas cultivated oyster (Manzoni and Schmitt, 1997).
In fact, numerous species of mangrove oysters have been described, all in the genus Crassostrea
; but the taxonomic identification is difficult and uncertain, so their geographical ranges are also often poorly known.
(Chanley & Dinamani 1980), illustrate that the morphological differences between early ontogenetic stages of species within the genus Crassostrea
and those within the genus Ostrea are quite striking.
This finding is similar to that reported by several authors in oysters of the genus Crassostrea
(Rodriguez-Jaramillo et al., 2008; Lenz & Boehs, 2011).
The development of oyster farming in Brazil has involved three species of the genus Crassostrea
: the native oyster Crassostrea rhizophorae (Guilding, 1828), the "mangrove oyster" Crassostrea gasar (Adanson, 1757) and the Pacific oyster Crassostrea gigas (Thunberg, 1793).
The morphology of the larval shell of Saccostrea glomerata (Gould, 1850) and a comparative study of the larval shell in the genus Crassostrea
Sacco, 1897 (OSTREIDAE).
The only other two American pinnotherid crabs, which are symbionts of oysters of the genus Crassostrea
in the Atlantic Ocean include Zoaps ostreum and Z.
The use of biofilm on the surface of oyster shell (Tamburri et al., 1992; Satuito et al., 1995) and the use of neurotransmitters such L-DOPA (L-3,4-dihidroxi-phenlyalaninne), epinephrine, and ammonia (N[H.sub.3]) has shown efficiency in increasing the settlement of larvae of the oyster from the genus Crassostrea
(Coon et al., 1985, 1990a, b; Fitt and Coon, 1992).
