General management practices including capture, handling and transportation in fish hatcheries can induce a stress response indicated by a plasma cortisol increase in many species. However, this phenomenon is not well established in cultured white st

To address the hypothesis that multiple stressors can have cumulative effects on the individual, we determined the effects of restraint (R) stress (4 h/day for 7 days), immunological (L) stress [lipopolysaccharide (LPS) injection, 0.45 μg/g body wt

We have long recognized the impact that pain, stress, and distress can have on the welfare of laboratory animals, or for that matter, any animal. Pain and stress can cause distress, and the biologic effects can compromise experimental results (Moberg

Commercial sturgeon farms in California have observed poor spawning performance and ovarian regression in fish maintained at constant 16–20°C water temperatures. The effects of the pre-spawning thermal regime on oocyte germinal vesicle migration (

Successful breeding of captive white sturgeon (Acipenser transmontanus) is dependent on the administration of exogenous gonadotropin releasing hormone agonists (GnRHa) to induce spermiation in males and ovulation in females. Since in other species st

Males and females of cultured white sturgeon, Acipenser transmontanus, mature at an average age of 4 and 8 years, respectively. However, the onset of ovarian vitellogenesis and puberty are highly asynchronous in the female stock. Gonadal cycles are a

The effects of chronic exogenous testosterone treatment on the synthesis and/or secretion of two sturgeon gonadotropins (stGTH I and stGTH II) were assessed in 2-year-old juvenile white sturgeon (Acipenser transmontanus) surgically implanted with sil

The effects of dopamine on the secretion of two sturgeon gonadotropins (stGTH I and stGTH II) in sexually mature male white sturgeon (Acipenser transmontanus) were evaluated. In Experiment I, sturgeon were given intraperitoneal injections of physiolo
