	abstract = {Greenshell{\texttrademark} mussels (GSM) are a mollusc endemic to New Zealand and are of economic importance to the New Zealand
aquaculture industry. The primary focus of the GSM industry is selection for increased meat weight, however, aesthetics also
influence marketability. This study focused on pedigree-based estimation of heritabilities and genetic correlations among GSM
traits collected during two harvest seasons: standard and winter. Sizes and weights were highly heritable (0.41{\textpm}0.07 to 0.92{\textpm}0.09),
and highly genetically correlated across traits and seasons (>=0.75{\textpm}0.07). Meat cover and gonad scores (measures of visual appeal)
had lower heritabilities than did size and yield traits (0.08{\textpm}0.03-0.25{\textpm}0.05). Under standard conditions, meat cover had a high
genetic correlation with gonad condition scores (0.85{\textpm}0.04). Under winter conditions the relationship between meat cover and
gonad scores was negative (-0.52{\textpm}0.19). Substantial GxE was observed across seasons (meat cover: rg=-0.58{\textpm}0.16; gonad:
rg=0.62{\textpm}0.11). Progress made from genetic selection to increase meat yield while controlling for the size may be slow, so selecting
for traits related to visual appeal may be preferable. Given that production traits are genetically similar across harvest conditions,
selection within standard conditions is likely to improve performance in both standard and winter harvests, thereby allowing for
an extended harvest period. However, the genetic improvement of visual appeal of the mussels is likely to be influenced by target
harvest season.},

	abstract = {Cryopreservation of gametes and embryos plays a key role in the advanced areas of animal production. It will also play  a central role in future aquaculture. The techniques to cryopreserve gametes are well understood in domestic animals such as sheep and cattle.  In contrast, research on shellfish cryopreservation is scarce. A major limitation of previous shellfish  work is that fertilisation or short-term survival has been taken as the measure of success, which has not been validated in  terms of successful development and growth of larvae. This manuscript briefly describes the approach to the problem by this research team and highlights some of the similarities and differences between the procedures used with shellfish and  domestic animal gametes.},
