In addition, protective measures that may assist in insulating wild clams from their farmed counterparts may include maturation control through triploidy
(Vadopalas & Davis 2004).
techniques developed for geoducks (Vadopalas & Davis 2004) appear to confer sterility (Vadopalas & Davis, unpublished) and are currently undergoing further evaluation.
Using a combination of selective breeding and triploidy
, aquaculture of oysters has become a reality.
Follow-up showed that of the 14 abnormal fetuses, 11 had trisomy 18, 1 had a triploidy
, and 2 had multiple severe anomalies but normal karyotypes.
Separate effects of triploidy
, parentage and genomic diversity upon feeding behavior, metabolic efficiency and net energy balance in the Pacific oyster Crassostrea gigas.
The effect of triploidy
on the growth and survival of the indigenous abalone, Haliotis midae, over a 24 month period under commercial rearing conditions.
Induction of triploidy
in the South African abalone, Haliotis midae, by method of hydrostatic pressure.
Recently, hypotonic shock has been used to induce triploidy
(Wang et al.
Previous studies have suggested that embryos with 3PN, which develop from ICSI zygotes, are endowed with mechanisms to correct triploidy
In this regard, the method to induce triploidy
by cold shock and the optimal experimental conditions to produce high percentage (90-100%) of triploid larvae at hatching has been reported (Alcantar-Vazquez et al., 2008).
Effects of different thermal shocks applications on survival, growth, triploidy
, biochemical parameters and enzyme activity of rainbow trout (oncorhynchusmykiss, w.

, parentage and genetic diversity on growth of the Pacific oyster Crassostrea gigas reared in contrasting natural environments.
