Prolactin, a Factor in Promoting Survival of Hypophysectomized Killifish in Fresh Water
The naturally occurring corticosteroids, cortisol and aldosterone, failed to promote survival of hypophysectomized Fundulus heteroclitus in fresh water. Extracts of Fundulus interrenal tissue, carpExpand

Sodium- and Potassium-Activated Adenosine Triphosphatase of Gills: Role in Adaptation of Teleosts to Salt Water
The activity of adenosine triphosphatase activated by sodium and potassium ions is greatly increased in the gill and pseudobranch of the euryhaline killifish, Fundulus heteroclitus, after itsExpand

Branchial Reduction and Renal Stimulation of (Na+, K+)-ATPase by Prolactin in Hypophysectomized Killifish in Fresh Water
THE discovery, in 1959, that prolactin enables hypophysectomized killifish (Fundulus heteroclitus) to live in fresh water1,2 stimulated much investigation of the osmoregulatory functions of thisExpand

The spawning reflex response of the killifish, Fundulus heteroclitus: isotocin is relatively inactive in comparison with arginine vasotocin.
The Fundulus spawning reflex activity of the teleostean neurohypophysial peptides, arginine vasotocin (AVT) and isotocin (IT), was assayed by criteria specified in earlier investigations. OneExpand
