Métodos reprodutivos da tilápia nilótica (oreochromis niloticus), a importância do melhoramento genético: uma revisão de literatura. Orientador: Wallace Silva do Nascimento. 2023. 34 f.

(SILVA et.al., 2015, Cap.1, Page 13 -14, RIBEIRO et al., 2012, SCHULTER; FILHO, 2018, ODA, 2015 apud FRANÇA, 2019 apud MOREIRA et al., 2007). It is a freshwater species that presents the following taxonomic classification: Teleost group; of the Peciform Order; Class Actinopterygii; Family Cichlidae and Subfamily Pseudocrenilabrinae. (SILVA et.al 2015, Chap.2, Page 23, MELO, 2022). It develops in tropical and subtropical environments, it has an accelerated growth rate, it is an omnivorous fish that has a very wide diet from phytoplankton; microcrustaceans, small fish to commercial feeds from the larval stage (ingesting in smaller quantities) in relation to other fish of carnivorous origin. Its ideal temperature is between 25 to 30°C. (CASTAGNOLLI, 1992; KUBITZA, 2000; GONZATEZ and QUEVEDO, 2001; ONO and KUBITZA, 2003; CYRINO and CONTE, 2006, MORI, 2012, TETU, 2013, MELO, 2022 apud FITZSIMMONS, 2000, MEURER et al., 2000, AYROZA, 2009, SILVA, 2015, KUBITZA, 2022). Due to the high reproductive capacity, early maturation, high fertility and annual spawning of Nile tilapias, a large overpopulation of small fish began to occur, which ended up leading to dissatisfaction on the part of the producers. In view of this, the proper cultivation of tilapias involved the control and manipulation of the reproduction of this fish, which led to preferring a production of individuals of a single sex, males (Oreochromis niloticus) in which they developed and grew better than females of the same gender, because they did not participate in the oral incubation of the eggs. (BORGES, 2004 apud POPMA & GREEN, 1990; BORGES, 2002 DONALDSON, 1996, PHELPS & POPMA, 2000; BEARDMORE et. al., 2001). The methods most used to obtain individuals of a single sex are: manual sexing, interspecific hybridization, chromosomal manipulation and sex reversal with the use of hormones.
