TL;DR: It is concluded that reproductive function is compromised in salmon which are retained in seawater during the spawning season because of differences in hormone levels, the dehydrated eggs, incomplete ovulation, and high adult mortality of fish in seaw water.

TL;DR: A positive conditioning approach was used, where a dewatering Stressor was associated with feeding, to help moderate the severity of the response of juvenile chinook salmon to transportation, and enhanced survival during transport, elevated resistance to the pathogen Aeromonas salmonicida, increased seawater adaptability, and helped the animals to cope with other Stressors relative to control groups.

TL;DR: Adult female coho salmon were injected intraperitoneally with the luteinizing hormone-releasing hormone analogue (LH-RHa) des-Gly 10 [D-Ala 6 ]-Lh-RH-ethylamide at various dosages to induce precocious final maturation.

TL;DR: Similarities in phenotypic characters (isozyme gene frequencies, life history, and morphology) among 35 stocks of coho salmon, OncorhynchuBkisutch, from Oregon, Washington, and California were compared by using agglomerative and divisive cluster analyses.

TL;DR: Effective inducers of ovulation in salmon held in fresh water were partly purified or purified salmon gonadotropin followed 3 d later by luteinizing hormone releasing hormone analogue (LH-RHa), and one injection of salmon pituitary extract (SPE) was ineffective in acceleration of maturation/ovulation of coho salmon.
