“…The use of polyploidy has become popular in bivalve aquaculture ( Ma et al, 2019 ), either due to gonadal sterility ( Piferrer et al, 2009 ; Dheilly et al, 2014 ; Zhang et al, 2017 ), to the increase in the cell volume and lack of compensation of cell number ( Guo and Allen, 1994 ), or even to the increased heterozygosity that promote larger and faster growth in bivalves ( Guo et al, 2009 ; Yang and Guo, 2018 ).…”

“…For this purpose, the determination of the moment of the exit of 50% of PB1 or PB2 after fertilization is important as a reference for the application of inducers ( Guo et al, 1996 ; Lavander et al, 2017 ; Melo et al, 2015 ). As in GVBD, salinity can also impact post-fertilization processes such as the timing of release or inhibition of polar bodies in bivalve mollusks ( Ma et al, 2019 ).…”

The knowledge about the effect of salinity on the physiological mechanism of bivalve reproduction is fundamental to improve production strategies in hatcheries. The present work evaluated the influence of different salinity concentrations (15, 20, 25, 30, 35 and 40 g⋅L −1 ) on pre- and post-fertilization development processes in the clam, Anomalocardia flexuosa , oocytes obtained by stripping. Salinity directly interfered with the germinal vesicle breakdown (GVBD) rate and in the cellular stability of unfertilized oocytes. Salinity concentrations between 30 and 35 g⋅L −1 provided better percentages of stable GVBD within 120 min, and incubation of oocytes in the salinity range of 30-35 g⋅L −1 for a time interval of 80-120 min provided > 80% GVBD. In the post-fertilization analysis, salinity affected the rate of the extrusion of the first and second polar bodies (PB1 and PB2). The release of 50% of the PBs was faster at a salinity of 35 g⋅L −1 , with an estimated time of 10 min for PB1 and 30 min for PB2. Thus, chromosome manipulation methodologies aiming triploids should be applied at 35 g⋅L −1 salinity, with application of post-fertilization shock before 10 min for PB1 retention or before 30 min for PB2 retention.

“…Both two oyster species were cultured in a 20‐m 3 concrete tank containing filtered seawater with a salinity of 28 and fed with Nitzschia closterium at a quantity of 250,000 – 30,0000 cells·ml −1 ·d −1 . The water temperature gradually raised from 6°C to 20°C and finally kept at 18–20°C for one month to ensure that the two oyster species mature synchronously (Ma et al, 2019; Wang et al, 2011; Xu et al, 2019).…”

The hybridization experiments have been made between Crassostrea ariakensis and C. gigas several times. However, it is difficult to obtain a large number of hybrid offspring, which becomes the bottleneck of subsequent cross‐breeding. To explore whether the production of hybrid larvae is affected by salinity, we investigated the effects of salinity (16, 20, 24, 28 and 32 psu) on the early activities of artificial hybridization between C. ariakensis and C. gigas at 23–24°C. In this study, the results showed that during artificial insemination, the appropriate salinity of high‐quality gametes in C. ariakensis and C. gigas was 20–32 psu and 24–32 psu respectively. Besides, the fertilization rate of AG (C. ariakensis♀ × C. gigas♂) and GA (C. gigas♀ × C. ariakensis♂) at 24–28 psu was significantly (p < .05) higher than that at 16–20 psu. For incubation, the optimal salinity of embryo incubation was 28 psu, under which all embryos of AG and GA can develop rapidly to the D‐larvae and yielded a high hatching rate. During larval rearing, the larval shell height and survival rate of AG were of no significant difference (p > .05) at all salinities, and the optimum salinity for larval growth and survival of GA was 24–28 psu. These findings can contribute to the increase in the hybrid progeny yield, which can serve as the new resource for genetic improvement of oyster germplasm.
