{"cited_by_count":1084076,"description":"This cluster of papers focuses on the reproductive physiology and endocrine disruption in fish, covering topics such as spermatogenesis, oogenesis, gonadotropins, estrogen receptors, environmental regulation of reproduction, eel migration, vitellogenin as a biomarker, and cryopreservation of gametes. It explores the impacts of environmental contaminants and hormonal manipulations on fish reproduction and gamete quality.","display_name":"Reproductive biology and impacts on aquatic species","domain_id":"1","external_ids":{"openalex":"https://openalex.org/T11505","wikipedia":"https://en.wikipedia.org/wiki/Fish_reproduction"},"field_id":"13","id":"T11505","keywords":[{"display_name":"fish reproduction","id":"fish-reproduction","score":0.5481,"url":"https://openalex.org/keywords/fish-reproduction"},{"display_name":"oogenesis","id":"oogenesis","score":0.2072,"url":"https://openalex.org/keywords/oogenesis"},{"display_name":"gonad development","id":"gonadal-development","score":0.34,"url":"https://openalex.org/keywords/gonadal-development"},{"display_name":"gonadosomatic index","id":"gonadosomatic-index","score":0.3918,"url":"https://openalex.org/keywords/gonadosomatic-index"},{"display_name":"vitellogenesis","id":"vitellogenesis","score":0.4693,"url":"https://openalex.org/keywords/vitellogenesis"},{"display_name":"sex reversal","id":"sex-reversal","score":0.4126,"url":"https://openalex.org/keywords/sex-reversal"},{"display_name":"vitellogenin","id":"vitellogenin","score":0.3862,"url":"https://openalex.org/keywords/vitellogenin"},{"display_name":"spawning","id":"spawning","score":0.2224,"url":"https://openalex.org/keywords/spawning"},{"display_name":"gonadal maturation","id":"gonad-maturation","score":0.3681,"url":"https://openalex.org/keywords/gonad-maturation"},{"display_name":"spawning season","id":"spawning-season","score":0.2253,"url":"https://openalex.org/keywords/spawning-season"},{"display_name":"fish breeding","id":"fish-breeding","score":0.2106,"url":"https://openalex.org/keywords/fish-breeding"},{"display_name":"gonad histology","id":"gonadal-histology","score":0.4789,"url":"https://openalex.org/keywords/gonadal-histology"},{"display_name":"11-ketotestosterone","id":"11-ketotestosterone","score":0.6818,"url":"https://openalex.org/keywords/11-ketotestosterone"},{"display_name":"methyltestosterone","id":"methyltestosterone","score":0.3988,"url":"https://openalex.org/keywords/methyltestosterone"},{"display_name":"broodstock","id":"broodstock","score":0.292,"url":"https://openalex.org/keywords/broodstock"},{"display_name":"amphibian reproduction","id":"amphibian-reproduction","score":0.3049,"url":"https://openalex.org/keywords/amphibian-reproduction"},{"display_name":"ovarian maturation","id":"ovarian-maturation","score":0.449,"url":"https://openalex.org/keywords/ovarian-maturation"},{"display_name":"induced spawning","id":"induced-spawning","score":0.681,"url":"https://openalex.org/keywords/induced-spawning"},{"display_name":"gynogenesis","id":"gynogenesis","score":0.3289,"url":"https://openalex.org/keywords/gynogenesis"},{"display_name":"crustacean reproduction","id":"crustacean-reproduction","score":0.4486,"url":"https://openalex.org/keywords/crustacean-reproduction"},{"display_name":"sex change","id":"sex-change","score":0.2883,"url":"https://openalex.org/keywords/sex-change"},{"display_name":"spermiation","id":"spermiation","score":0.5853,"url":"https://openalex.org/keywords/spermiation"},{"display_name":"oocyte size","id":"oocyte-size","score":0.2924,"url":"https://openalex.org/keywords/oocyte-size"},{"display_name":"teleost reproduction","id":"teleost-reproduction","score":0.7469,"url":"https://openalex.org/keywords/teleost-reproduction"},{"display_name":"broodstock management","id":"broodstock-management","score":0.3947,"url":"https://openalex.org/keywords/broodstock-management"}],"legacy_keywords":["Spermatogenesis","Oogenesis","Endocrine Disruption","Gonadotropins","Estrogen Receptors","Environmental Regulation","Gonadal Development","Eel Migration","Vitellogenin","Cryopreservation"],"openalex_id":"https://openalex.org/T11505","source_created_date":"2024-01-23T15:27:10","source_updated_date":"2026-10-17T03:02:00","subfield_id":"1314","url":"/topics/T11505","works_api_url":"https://api.openalex.org/works?filter=topics.id:T11505","works_count":81693,"label":"Reproductive biology and impacts on aquatic species","provider":"openalex","revision":"705b9a93d310d09e","taxonomy_revision":"f050b5d4780b1289","title":"Reproductive biology and impacts on aquatic species","kind":"topic-directory","aeo_cohort":"topic-directory","catalogue_revision":"f050b5d4780b1289","numeric_address":"36182748121539147","address_version":"morton4x16-v1","coordinates":[1,13,1314,11505],"answer_status":"Directory metadata; local answer requires separate source review","truth_status":"Subject descriptor, not a factual answer or a demonstrated knowledge gap","reviewed_answer":null}
