“…This is likely to be the result of the spawning behaviour of adult invertebrates and high dispersal ability of marine invertebrate larvae. The larvae of this species have very long pelagic duration, which is around 21 to 35 days (Laxmilatha et al, 2011). It is likely that the larvae of Asian green musseltend to drift away from their natal habitat and that this in turn increases the gene flow between populations and lowers the degree of differentiation between populations.…”

“…P. viridis employs external fertilization whereby males and females Asian green mussels release gametes directly into the water during spawning. The Asian green mussel adult is sessile throughout its life whereas the larvae of Asian green mussel have long pelagic duration, which last around 21 to 35 days after fertilization (Laxmilatha et al, 2011).…”

The Asian green mussel (Pernaviridis) is a bivalve species with a high economic value. The waters surrounding the Malaysian state of Sabah hosts a wide range of geographically distributed populations of P. viridis whose population structure is unknown. This study was conducted to elucidate the genetic diversity and population structure of Asian green mussel from six sites located along the coastline of Sabah based on the mitochondrial DNA control region (D-loop). The complete D-loop sequences of 197 individuals were recovered by amplification using PCR, followed by DNA sequencing. Interpretation of the results revealed that the P. viridis populations exhibited high haplotype diversity (H d =0.912±0.0002) and low nucleotide diversity (π=0.00890±0.00066). The AMOVA analysis showed  ST was 0.02322 (P value<0.05), which is indicative of low but significant structuring. Pairwise ST ranged from low to moderate indicating population differentiation. Five out of the fifteen population pairs showed significant population differentiation. Both AMOVA and pairwise  ST suggest there were significant population subdivisions in Asian green mussel population in Sabah. Although the Asian green mussel population in Sabah has gone through a severe mass mortality, evidence for genetic bottleneck was not detected. However, a smaller population size after a severe demographic reduction can cause the population become vulnerable. Thus, regular monitoring of Asian green mussel population is required to keep track of fluctuations in population size and composition. This study provided new population genetic information which is crucial for establishing fisheries management strategies for this species.

“…Various induced spawning methods have been used on dierent bivalve species in order to produce seeds in a hatchery. Induced spawning, larval rearing and spat production of several mussel species, such as Perna viridis (Laxmilatha et al 2011), Modiolus capax (Farfán et al 2007) and Mytilus edulis (Galley et al 2010) have been successfully carried out in laboratories and hatcheries; however, little attention has been paid to the production of oyster spat in large-scale hatcheries and the oyster industry still relies on the supply of seed from the wild (Alfaro et al 2010;Laxmilatha et al 2011;Wong and Arshad, 2013).…”

ABSTRACT. The eectiveness of two stimuli (thermal and salinity shock) in inducing spawning in the eastern oyster Crassostrea virginica was tested under laboratory conditions. Organisms were obtained in Machona Lagoon, located in Sánchez Magallanes, Tabasco. Temperatures used were 10, 15, 20, 25 and 30• C and the salinities were 10, 15, 20, 25 and 30 psu. The objective of this work was to determine the eects of salinity and thermal shock on spawning of C.

“…Induced spawning, egg and larval development and spat production in hatchery have been carried out by Tan (1975), and Laxmilatha et al (2011). Earlier reports on the green mussel fishery, biology and spat settlement are by Kuriakose et al (1984), Selvaraj (1988), Appukuttan et al (2001), Thomas et al (2002) and Laxmilatha and Sivadasan (2007a).…”
