Natural fish populations have declined during the last several decades because of environmental degradation and over-fishing. This has resulted in an increased effort in the development of techniques for hatchery production of fish. Traditional aquaculture species such as trout, catfish, common carp, gold...

متن کاملHormone Induced Spawning of Summer Flounder Paralichthys dentatus
-During their first year in captivity, summer flounder Parulicthys denratus were induced to spawn with gonadotropin releasing hormone analogue (GnRHa) implants, injected carp pituitary extract (CPE) or human chorionic gonadotropin (hCG) injections. The percentage of fertile eggs was greatest (-69%) in CPEtreated females. CPE, but not GnRHa or hCG, was capable of stimulating oocyte growth (incre...
