Ovaprim injections significantly enhanced ovulation and sperm production compared to controls. Medium temperature (22 \u00b0C) produced the highest ovulation rates, fastest ovulation timing, and optimal sperm quality (motility and morphology) compared to high (28 \u00b0C) and low (16 \u00b0C) temperature groups. The low-temperature group exhibited reduced sperm motility duration and higher rates of sperm and larvae damage. The sperm volume of the high-temperature group was higher, but their post-injection survival rates were lower. Furthermore, the lowest spawning rate and low egg quality were noted in the high temperature. Cryopreservation using extender E4 (15% DMSO) exhibited superior post-thaw sperm motility and achieved higher fertilization rates. Fertilization rates, embryo development, and larval survival were all highest at the medium temperature. Larvae hatched from fresh sperm at medium temperature exhibited faster growth and fewer deformities. These findings suggest that hormone stimulation coupled with a medium temperature regimen is critical for successful artificial reproduction in goldfish. Cryopreservation with extender E4 holds promise for sperm banking; however, further optimization is necessary to improve fertilization success with thawed sperm. Future research could explore the influence of temperature on sperm physiology and refine cryopreservation protocols to enhance fertilization rates.<\/jats:p>","DOI":"10.3390\/ani14182701","type":"journal-article","created":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T09:43:13Z","timestamp":1726652593000},"page":"2701","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Hormone-Driven Temperature Optimization for Elevated Reproduction in Goldfish (Carassius auratus) under Laboratory Conditions"],"prefix":"10.3390","volume":"14","author":[{"given":"Zeynab","family":"Taheri-Khas","sequence":"first","affiliation":[{"name":"Department of Biology, Faculty of Science, Razi University, Kermanshah 6714414971, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad","family":"Gharzi","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Razi University, Kermanshah 6714414971, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3389-1877","authenticated-orcid":false,"given":"Somaye","family":"Vaissi","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Razi University, Kermanshah 6714414971, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-4415-6967","authenticated-orcid":false,"given":"Pouria","family":"Heshmatzad","sequence":"additional","affiliation":[{"name":"Department of Fisheries, Faculty of Fisheries and Environmental Sciences, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan 4918943464, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zahra","family":"Kalhori","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Razi University, Kermanshah 6714414971, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"516","DOI":"10.1016\/j.ygcen.2009.03.007","article-title":"Broodstock Management and Hormonal Manipulations of Fish Reproduction","volume":"165","author":"Mylonas","year":"2010","journal-title":"Gen.
