Growth trials were conducted using hatchery produced spat of Pinctada imbricata fucata (Gould, 1850) having average dorso-ventral measurement (DVM) of 3.99 mm, hinge length (HL) 3.94 mm, thickness (THK) 1.25 mm and weight (WGT) 0.008 g. The first experiment was a comparative growth assessment of...

The irregular supply of natural mussel seed for aquaculture has seen an increase in the establishment of hatcheries to produce a reliable source of mussel seed. While many of the factors influencing fertilisation and early survival of hatchery-produced mussel larvae have been explored, little is...

Bivalve molluscs are a high quality animal protein source for humans, and the demand for farmed bivalves is increasing. Among the bivalve molluscs, the Portuguese oyster Crassostrea angulata, is one of the most popular species and is intensively farmed in warm water. In order to further increase...

Mariculture of green mussel (Perna viridis) is being hindered by reliance on seed from the wild. Hatchery production helps increase seed stock, but little is known about the factors that may affect hatchery practices. Development of hatchery protocols to optimise production is therefore needed....

Stocking density determines the performance of polyculture. However, the underlying mechanisms of how density affects the behavior of aquaculture animal are still unclear, especially the predation and competition. Here we selected a typical polyculture system containing predator swimming crabs (...

The Pacific oyster (Crassostrea gigas) and the Portuguese oyster (C. angulata) are important oyster species for commercial aquaculture. In this study, three stocking density regimes, including 20, 30 and 40 oysters/basket, were used to study the effects of stocking density on growth performance,...

The present study determined the effect of larval stocking density on larval yield (number of live larvae at the end of the experiment), competent larvae (number of live larvae at the end of the experiment retained on a sieve with mesh size of 236 μm (1st experiment) and 239 μm (2nd experiment)),...

Objective: We estimated the effects of diets, substrate and stocking density on the survival rate and growth of juvenile mussel obtained from in vitro culture of glochidia in pink heelsplitter, P.alatus. Result: The results showed that the juvenile mussel in Group A1 with pond mud substrate and...

Commercialization of pearl culture requires large scale hatchery production of larvae. The survival of larvae depends on stocking density, environmental factors, diets and diseases. The results of experiments using 4 stocking densities at the rate of 100, 1000, 2000 and 3000 larvae L^-1 of filtered...

To evaluate the effect of stocking density on pre-fattening growth and survival, Manila clam seeds from three different batches (B1, B2, and B3) were farmed in plastic net lanterns at two sites (western and northern) in Sacca degli Scardovari (Italy). Different stocking densities were compared,...
