Journal ArticleDOI
The parr-smolt transformation (smoltification) and seawater adaptation in salmonids a review of selected literature
TL;DR: This review provides fishery biologists and fish culturists with a summary of those published reports relating to the morphological, behavioral and biochemical changes associated with smoltification and seawater adaptation in anadromous salmonids.
Journal ArticleDOI
Growth hormone and insulin-like growth factors in fish: where we are and where to go.
Manfred Reinecke,Björn Thrandur Björnsson,Walton W. Dickhoff,Stephen D. McCormick,Isabel Navarro,Deborah M. Power,Joaquim Gutiérrez +6 more
TL;DR: This communication summarizes viewpoints, discussion, perspectives, and questions, put forward at a workshop on "Growth hormone and insulin-like growth factors in fish" held on September 7th, 2004, at the 5th International Symposium on Fish Endocrinology in Castellon, Spain.
Journal ArticleDOI
Isolation and characterization of two coho salmon gonadotropins, GTH I and GTH II.
TL;DR: Analysis of coho salmon GTH I and GTH II on reversed-phase high-performance liquid chromatography revealed that they consist of alpha and beta subunits with N-terminal amino acid residues of Tyr, Gly and Tyr,Ser, which is similar to what has previously been found in chum salmon.
Journal ArticleDOI
Changes in plasma thyroxine during smoltification of coho salmon, Oncorhynchus kisutch.
TL;DR: Results support the contention that the thyroid plays a role in regulation of salmon smoltification, and the magnitude, duration and time of onset of the T-4 surge varied in the different stocks of coho salmon investigated.
Journal ArticleDOI
Comparison of extraction methods and assay validation for salmon insulin-like growth factor-I using commercially available components.
Munetaka Shimizu,Munetaka Shimizu,Penny Swanson,Haruhisa Fukada,Akihiko Hara,Walton W. Dickhoff,Walton W. Dickhoff +6 more
TL;DR: It is concluded that with this RIA extraction is necessary for measurement of salmon IGF-I in plasma since measured values were routinely lower in unextracted samples, and AE, AEC, and SP-Sephadex extractions are applicable to the IGF- I RIA using the commercially available components.
