Journal of Bioscience and Bioengeering These temperatures to transfer to the field for growth to commercial size. A detailed description of the methods and formulae was described in a previous article Nieves-Soto et al. Bivalve mollusk culture is a profitable economic activity worldwide.

Cortezienxis culture of the Cortez oyster Crassostrea corteziensis from northwestern Mexico: The concentration of treatment ingredients in the containers was restored with every seawater change.


This study reports the in vivo effect of three bacteria species, one marine yeast strain, a commercial probiotic formulation, and a commercial antibiotic on growth, survival, and antioxidant response in C. Considering all life stages, Proteobacteria was the most abundant phylum, but it showed variations at the genus level between the postlarvae and the adult oysters.

Improved growth rate and disease resistance in farmed Ctassostrea midae through probiotic treatment.

Means within columns sharing superscripts are not significantly different p N 0. Energetic physiology of the Caribbean scallops Argopecten nucleus and Nodipecten nodosus fed with different microalgal diets. As a general pattern, consumed energy Cabsorbed energy Aand SFG decreased with a corresponding decrease in the proportion of live microalgae in the diet.

We investigated the consumed, absorbed, and respired energy, the absorption efficiency, and calculated SFG in juvenile Cortez oysters fed nine isocaloric diets prepared with a mixture of microalgae Tisochrysis lutea, Chaetoceros calcitrans and Ch.

Probiotic bacteria as biological control agents in aquaculture. Mean growth rates in shell height a and wet weight areas e. Changes in the scope for growth of blood cockles Anadara granosa exposed to industrial discharge. This reduced ingestion may be related to the physical properties of the cereal particles, such as size, surface, and palatability. Probiotics have proven advantageous in domestic animal production and the evidence supports the same conclusion for microbial management in rearing aquatic animals Carnevali et al.


Energy content of food particles was slightly higher for the two cereal products than for microalgae Table 2and diets containing higher proportion of cereals required a lower particle density to meet the energy required.

DNA samples from the oysters were amplified, and 31 sequences belonging to 13 phyla including Proteobacteria, Bacteroidetes, Actinobacteria and Firmicutes and genera were generated.
