“…Among A. japonicus with a body length of 12–18 cm, the percentage of triploid A. japonicus was 1.37% higher than that of diploid A. japonicus . This was consistent with the triploid breeding results of other aquatic species (Peruzzi et al 2018 ; Liu et al 2018 ; Garnier-Géré et al 2002 ). Following a comparative analysis, the aestivation time of triploid A. japonicus was shorter.…”

Polyploid breeding is widely used in aquaculture as an important area of new research. We have previously grown Apostichopus japonicus triploids with a growth advantage. The body length, body weight, and aestivation time of triploid and diploid A. japonicus were measured in this study, and the transcriptome and metabolome were used to examine the growth advantage of triploids A. japonicus. The results showed that the proportion of triploid A. japonicus with a body length of 6–12 cm and 12–18 cm was significantly higher than that of diploid A. japonicus, and triploid A. japonicus had a shorter aestivation time (39 days) than diploid (63 days). We discovered 3296 differentially expressed genes (DEGs); 13 DEGs (for example, cyclin-dependent kinase 2) related to growth advantage, immune regulation, and energy storage were screened as potential candidates. According to Gene Ontology (GO) enrichment analysis, DEGs were significantly enriched in the cytoplasm (cellular component), ATP binding process (molecular function), oxidation–reduction process (biological process), and other pathways. According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment data, DEGs were significantly enriched in ribosome production and other areas. We discovered 414 significant differential metabolites (SDMs), with 11 important SDMs (for example, nocodazole) linked to a growth advantage. SDMs are significantly enriched in metabolic pathways, as well as other pathways, according to the KEGG enrichment results. According to a combined transcriptome and metabolome analysis, 6 DEGs have regulatory relationships with 11 SDMs, which act on 11 metabolic pathways together. Our results further enrich the biological data of triploid A. japonicus and provide useful resources for genetic improvement of this species.

“…Some individuals with specific alleles or genotypes are sensitive to high-pressure induction and cannot survive, resulting in the deletion or frequency reduction of the allele. Such phenomena could also be found in artificial induced triploid (Liu et al, 2018). Therefore, it is easy to explain the decrease of genetic diversity in 4n2 population compared to that in 2n2 population.…”

Artificial tetraploid induction is one of the important techniques of fish chromosome manipulation, and it is the first step for triploid breeding. There are a few reports to artificial induction of tetraploid in marine fish. The induction and survival rates were usually low. We firstly optimized the tetraploid induction conditions in turbot Scophthalmus maximus, one of the most important maricultural fish in China and Europe. For the initiate time of treatment, which is the most important factor in tetraploid induction, the first cleavage index (FCI) was used to reduce the influences of genetic origin and environment factors. Overall, the optimal initiation time for pressure shock was 15 min before the first cleavage at 14.8-15.5 • C. The optimal treatment pressure and treatment duration were 67.5 MPa and 6 min. The regression equation prediction model was: The optimal initiation time = 0.982 FCI − 12.182 or the optimal initiation time = 0.85 FCI. Then two tetraploid induction (4n1 and 4n2) populations were obtained under the optimal conditions with diploid controls (2n1 and 2n2). The induction rates in tetraploid induction (4n) populations at hatched larvae stage could reach 100%. The genetic structure of these two 4n populations was also studied. Two to four alleles in each locus were detected in diploid (2n) and 4n populations, respectively. Private alleles were only appeared at locus Sma-USC21, with two alleles lost in 4n populations. Eleven and fourteen loci in 2n and 4n populations respectively showed a negative genetic deviation index. 3D-FCA analysis showed that the two 2n and two 4n populations have obvious differences. The numbers of locus deviating from Hardy-Weinberg equilibrium in 2n1, 4n1, 2n2, and 4n2 populations were 6, 9, 12, and 7, respectively. Overall, 12 loci in either 2n or 4n population deviated from Hardy-Weinberg equilibrium. Tetraploid induction population showed lower heterozygosity and higher heterozygote deletion.

“…There are many studies comparing growth parameters, meat yields, and biochemical compositions of diploid and triploid fish (Manor et al, 2012;Kızak et al, 2013;Weber et al, 2014;Wang et al, 2015;Karbalaei et al, 2017;Liu et al, 2018;Ignatz et al, 2020;Meiler and Kumar, 2021).

The purpose of this study was to evaluate the fatty acid contents in various tissues (fillet, liver, gonad) of different ploidy (triploid and diploid) and sex (female and male) rainbow trout (Oncorhynchus mykiss) in the breeding season. In the study, diploid and triploid rainbow trouts belonging to the same age group (3+) were used. Fish were fed with commercial feed containing 45% crude protein and 20% crude fat until satiation. At the end of the 75-day study, biometric measurements of the fish were made and the tissues were stored in a deep freezer until biochemical and fatty acid analysis. The first finding of this study identified that ploidy (triploid and diploid) affects the biochemical and fatty acid composition of rainbow trout. The second major finding was that the polyunsaturated fatty acid values were higher and the saturated fatty acid values were lower in all tissues (especially female gonads) than other fatty acids. The results also indicate that the comparative among the biochemical and fatty acid composition of the fillet, liver, and gonad of rainbow trout is further illuminated by these data.
