Larval development of Crassostrea is characterized by three larval phases: larva D, Umbo and Pediveliger. In Pediveliger the larvae are near settlement and metamorphosis in hard substratum. In this work, recruitment of oysters’ larvae of genus Crassostrea (C. rhizophorae and C. brasiliana) was studied in Guaratuba Bay (Paraná – Brazil) through analysis of artificial collectors placed in three points: Point I (bay ́s entrance), Point II (cultivation park) and Point III (medium sector of the bay…

USE OF ARTIFICIAL COLLECTORS TO OBTAIN OYSTER SEEDS IN BABITONGA BAY, SANTA CATARINA, BRAZIL
TLDR
Results demonstrate that artificial collectors present a higher performance for the settlement of oyster species inappropriate for farm cultivation (C. talonata and Ostrea sp.), which raises environmental and commercial concerns about the maintenance of the natural oyster population in Babitonga Bay.
The effect of density on the cultivation of the native mangrove oyster Crassostrea tulipa (Lamarck, 1819)
TLDR
A high survival rate (≥98%) was found in the nursery and juvenile phases, and the animals' individual average weight and H/L ratio were negatively influenced by a density of 100 ind/0.10 m or bigger.
Effects of Light Intensity and Wavelength on the Phototaxis of the Crassostrea gigas (♂) and Crassostrea sikamea (♀) Hybrid Larvae
TLDR
The results indicated that hybrid oyster larvae had positive phototaxis to specific light intensity and wavelength, and that the acceptable light intensity range of the eyespot hybrid larvae expanded to 5–10 lx, but no higher than 15 lx; besides, the hybrid larvae behaved negatively to the light over 25 lx.
Fijación de invertebrados en tres tipos de substratos artificiales en el estero de Sabancuy, Campeche, Golfo de México
Para los invertebrados sésiles, el comportamiento del asentamiento larval y la selección del substrato final para su fijación es crítico para el posterior desarrollo del organismo adulto. En el

Behavior of oyster (Crassostrea virginica) larvae in flume boundary layer flows
TLDR
It is indicated that larvae are capable of rapid acceleration and that they may be able to control their approach to the bottom under a much wider range of conditions than had previously been suspected.

The spatial and seasonal variations of the micro-zooplankton abundance in a subtropical estuary were studied during a year. Five sampling sites were monthly sampled in Guaratuba Bay, Parana State,
Transport of bivalve larvae in the James River, Virginia
TLDR
Setting patterns suggest two types of seed areas in Chesapeake Bay: high freshwater discharge, open or flushing estuaries with light spatfalls that decrease in intensity with distance from the river mouth; the James River is a typical example; and low discharge, trap-type estuary where intensive sets are heaviest near the head of the saline sector; examples are the Piankatank and Great Wicomico rivers in Virginia.
Hydrodynamic of Guaratuba Bay , PR , Brazil
The bay of Guaratuba is an estuary located in the coastal plain of the coast of the Paraná State, Brazil, in its southern premise (25 51.80'S, 48 38.20'W Figure 1). The bay has an area of 50,19 km
Oyster spat recruitment in Espírito Santo State, Brazil, using recycled materials
TLDR
Spat settlement was significantly higher on oyster shell, tile and tire collectors, mainly at points with higher salinities, such as Praia do Coqueiro in Anchieta and on Meio and Cabrito Islands in Piuma.
Oyster larval transport in coastal Alabama: Dominance of physical transport over biological behavior in a shallow estuary
TLDR
A persistent gradient decreasing from west to east in the model results at time scales of overall average, season, and each survey in 2006 suggests that the larval supply may be responsible for the corresponding gradient in oyster spat settlement observed over the past 40 years.
Influence of the type of collector and collector preparation periods on the settling rate of the scallop Nodipecten nodosus L. in the laboratory
TLDR
The feasibility to improve and facilitate regular production of N. nodosus spats for promotion of the growth of scallop culture in Brazil is indicated and the settling rates of netlon collectors with pine leaves were up to 19 times higher than those of the other types of collectors.
