“…Similarly, lower survival of triploid larvae was also observed by Chourrout et al [ 56 ]. Triploidisation is the most common type of polyploidization that results in the formation of individuals with a triploid (3n) genome, and is characterized by the presence of an additional ½ genome—i.e., triploid sterlet have ~180 chromosomes [ 57 ]. Pressure shock techniques were more successful in retaining the second polar body in sturgeons [ 58 , 59 ].…”

The objective of the present research was to study the effect of cold shock (3 °C and 6 °C) on fertilized eggs of the sterlet, Acipenser ruthenus L. Cold shock was applied for various durations (30, 60 and 90 min) and the ploidy levels, survival, and genotypes of the treated embryos/larvae were recorded. Analysis of ploidy levels confirmed the presence of diploid, triploid, and mosaic (1n/2n, 2n/3n, and 1n/2n/3n) genotypes in experimental groups, while it was strictly diploid in control groups. Microsatellite genotyping confirmed both the incidence of polyspermy and retention of the 2nd polar body in experimental groups. However, patterns of inheritance in all diploid offspring in experimental and control groups revealed classical Mendelian disomic inheritance. Interestingly, the observed mosaic sterlets had normal morphology and were alive. However, some larvae had abnormal morphology which may be due to haploid syndrome. In all treatment groups (treatments: 3 °C–30 min; 3 °C–60 min; 3 °C–90 min; 6 °C–60 min), where the percentage of polyploid/mosaic larvae were high, the mortality was also high. Whereas, in the control groups (where there were only diploid (2n) larvae), the mortality was relatively low.

“…The deformities (particularly mandibular) are more common in triploid fish than in their diploid counterparts. 4,58 According to Fjelldal et al 59 and Smedley et al, 60 triploids have a higher dietary phosphorus requirement than diploids owing to the higher per-cell nucleic acid content, which is considered a risk factor for vertebral deformities. 61 Heavy metals cause deformities in fish and are specific to each metal, but in most cases, the pathway by which it causes deformities is still unidentified.…”

“…Water temperature significantly affects jaw deformity in the larvae of golden pompano, Trachinotus ovatus ; the prevalence of jaw deformities was higher at 33°C, while it was lowest at 26°C, and the finding also suggests that the gene expression of BMP4 proteins associated with high jaw deformity and elevated water temperature 55 . Fopp‐Bayat et al 4 applied cold shock during the early phase of embryonic development. They observed several types of deformities, such as caudal scoliosis, c‐shaped larvae, yolk sac with oedema or shortened yolk sac in sterlet, Acipenser ruthenus and also found that the prevalence of deformities was higher in mosaic and triploid larva than their diploid counterpart 4 …”

Several factors, such as physicochemical characteristics of water (temperature, water current velocity, salinity and pH), pollution, nutrition, genetic factors and farming infrastructure, have been identified for inducing deformities in fish.…”

Fish deformities are detrimental to aquaculture and conservation initiatives; it is also an ethical problem and causes substantial financial losses to the aquaculture industry. The exact mechanism of deformities is still a mystery. Several factors cause deformities in fish; it seems that the deformations are inevitable but can be minimised by adopting good aquaculture practices such as proper broodstock husbandry, standard breeding and larval rearing protocol, management of water quality parameters, and providing nutritionally balanced feed, especially to the broodstock and developing larvae. In addition, it can be minimised by early detection of deformities, especially at the embryonic and larval stages. Monitoring of stocking materials should be an essential part of responsible aquaculture and conservation programmes; stocking materials should be free from any types of deformities as it affects not only aquaculture production, profitability and success of conservation programmes but also the reoccurrence of deformities in nature. The mechanism behind deformities and the development of low‐cost, robust methods/tools for detecting deformities in fish remain a challenge. Still, the opportunity exists to develop a robust marker that can predict deformities even at early embryonic and larval stages.
