Triploid individuals were obtained after temperature shock (40\u00b0C for 2 min) at 2 min post-fertilization and reared until 175 days post-fertilization (dpf). Intact eggs were used to obtain the diploids. Gonads were collected for histological analysis at 83, 114, 144 and 175 dpf. Diploid females and males presented normal oogenesis and spermatogenesis through all the experimental period. Conversely, stereological analysis revealed that triploid females were sterile and oogonia were the prevalent cell type in the ovaries. Triploid males presented increased amounts of spermatocyte cysts and a large area of lumen when compared with diploids and in addition the amount of spermatozoa was lower than that observed for diploids. However, some triploid males presented spermatogenesis similar to diploids. Therefore, we concluded that triploidization is an interesting alternative to produce sterile individuals in <jats:italic>A. altiparanae<\/jats:italic>.<\/jats:p>","DOI":"10.1017\/s0967199417000399","type":"journal-article","created":{"date-parts":[[2017,8,2]],"date-time":"2017-08-02T05:52:38Z","timestamp":1501653158000},"page":"537-544","source":"Crossref","is-referenced-by-count":25,"title":["Stereological analysis of gonads from diploid and triploid fish yellowtail tetra <i>Astyanax altiparanae<\/i> (Garutti &amp; Britski) in laboratory conditions"],"prefix":"10.1017","volume":"25","author":[{"given":"Nivaldo","family":"Ferreira do Nascimento","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di\u00f3genes Henrique","family":"de Siqueira-Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matheus","family":"Pereira-Santos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takafumi","family":"Fujimoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Augusto","family":"Senhorini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura Satiko Okada","family":"Nakaghi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George Shigueki","family":"Yasui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2017,8,2]]},"reference":[{"key":"S0967199417000399_ref024b","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygcen.2009.02.013"},{"key":"S0967199417000399_ref017","doi-asserted-by":"publisher","DOI":"10.1111\/j.1095-8649.2010.02613.x"},{"key":"S0967199417000399_ref008","doi-asserted-by":"publisher","DOI":"10.1017\/S0967199416000101"},{"key":"S0967199417000399_ref001","doi-asserted-by":"publisher","DOI":"10.1111\/jwas.12390"},{"key":"S0967199417000399_ref013","doi-asserted-by":"publisher","DOI":"10.20950\/1678-2305.2016v42n4p734"},{"key":"S0967199417000399_ref010","doi-asserted-by":"publisher","DOI":"10.3354\/aei00006"},{"key":"S0967199417000399_ref003","article-title":"Effectiveness of triploidy as a management tool for reproductive containment of farmed fish: Atlantic salmon (Salmo salar) as a case study","author":"Benfey","year":"2015","journal-title":"Rev.
