Carp (Cyprinus carpio L.) is a widely cultivated Indonesian fishery commodity. The increasing demand for carp can be used as an opportunity to increase the production and income of farmers and fulfill the target of increasing the nutrition of the residents. The heat shock method is one method that is often used because the process is simpler than the others. Polyploidy analysis was carried out by counting the number of nucleoli in fish resulting from polyploidization. The results of the ploidization analysis of carp in this study showed that there were variations in the number (frequency) of nucleoli per cell in diploid, triploid, and tetraploid fish. The body size of tetraploid fish is larger than that of triploid fish. But triploid fish have a larger body size than diploid fish. Tetraploid goldfish have a larger size and nucleus and cell contents when compared to triploids, even more so with diploids. The more the number of cells causes the volume of cells in the body to increase, so that the body size or growth of the tetraploid carp is higher. The growth of organisms is also a process of multiplying the number of cells and increasing the volume of cells.

“…Apomixis is the dominant mode of reproduction in this species, with high commercial potential (Worthington et al 2019). However, this mode of reproduction, common in polyploid individuals, prevents self-fertilization and hybridization among existing elite genotypes or with sexual genotypes at different ploidy levels (Morais et al 2018, Baldissera et al 2020, Sales et al 2021.…”

“…Cytogenetic studies have revealed that U. brizantha and U. decumbens are predominantly tetraploid (2n = 4x = 36) and apomictic (Ricci et al 2010, Morais et al 2018, Matias et al 2020. Despite the predominance of tetraploidy, diploid plants have been reported () in the two species (Ricci et al 2010).…”

High seed yield is a fundamental characteristic of apomictic and sexual hybrids of the genus Urochloa P. Beauv. (syn. Brachiaria (Trin.) Griseb.). It has been suggested that there is an association between polyploidy, the presence of meiotic irregularities, and low seed formation in this genus. The present study aimed to correlate these characteristics in Urochloa polyploid sexual interspecific hybrids in relation to the production of pure seeds. Segregational and non-segregational abnormalities were shown to led to cause the formation of tetrads with micronuclei, microcytes, polyads, and anomalous end products. The correlation between the percentage of meiotic abnormalities and the total production of pure seeds was negative and significant. To our knowledge, this is the first research with sexual polyploid hybrids from Urochloa and is relevant to identify hybrids with less frequent meiotic abnormalities and higher seed yield, with promising female parents for the breeding program.

This study aims to explain the variation of polyploidy in catfish. This research method is literature study and literature review. The results showed that there were several forms of polyploid interpretation that were often performed on Clarias gariepinus. The effects of fish polyploidy will produce fish seeds with several advantages such as fast growth, resistance to disease and high tolerance to the environment. In conclusion, the form of variation that is often done produces tetraploid and triploid catfish. Keywords: Polyploidy, Tetraploid, Triploid
