Circulating concentrations of estradiol (E2), vitellogenin (VTG), thyroxine (T4), triiodothyronine (T3) and insulin were measured in reproductively maturing four and five year-old Atlantic salmon. Blood samples were collected from the fish in seawater for one year prior to their spawning in November in fresh water. In females, E2 and VTG were low but detectable from December to July, and then increased to peak levels in September and October. Plasma levels of T4 and T3 were relatively constant in winter and spring, and decreased in July. Plasma concentration of T4 increased in November when the fish returned to fresh water. Plasma T3 levels remained low during the autumn. Both T4 and T3 levels tended to be higher in males than in females during September through November. Plasma insulin concentrations increased during the spring to peak values in May, and then decreased in June and July in fish of both sexes. There was a significant elevation of plasma insulin in males during October, and the levels in males tended to be higher than those found in females during final maturation.

“…Four of the fish were also injected with T 3 (sodium salt, Sigma, in dimethylsulfoxide (DMSO) at a concentration of 200 to 250 mg/ml). The dosage of the intramuscular hormone injections was 20 + 2 g hormone/g body weight (after Detlaff and Davydova 1979). The remaining four prespawning female striped bass were injected with DMSO alone.…”

Elevation of the triiodothyronine (T3) content of striped bass (Morone saxatilis) eggs by maternal T3 injection confirms the uptake of T3 by oocytes. The resulting offspring were influenced favorably by the T3, as seen in quantitative indices of development. As reported previously, larvae from T3-supplemented eggs raised under laboratory conditions exhibited increased body area, length, dry weight, and rates of swimbladder inflation and survival, compared to controls. Also, the T3 content of unfertilized oocytes correlated positively and highly significantly with survival to two weeks of age within individual cohorts (Brownet al., 1988). In the present study, the survival of experimental and control striped bass was monitored through the fingerling stage, under hatchery production conditions. The rate of recovery of maternally T3-treated cohorts from pond-culture was approximately fourfold that of controls. The striking effects of T3 enrichment of eggs on offspring indicate the potential contribution of maternal hormones in striped bass development, and suggest possible applications in aquaculture.

“…An investigation by Dettlaff and Davydova (1979) (Olivereau, 1979). The aim of the present work was to determine if the addition of T 3 to the incubation medium would influence the maturational response of carp oocytes to gonadotropin or selected steroid hormones (Epler, 1981a, b, c fig.…”

Summary. The effects of triiodothyronine (T 3 ) and of gonadotropic and steroid hormones on carp oocyte maturation in vitro were investigated using ovarian fragments from 5 females that had completed vitellogenesis.The percentages of mature oocytes were consistently greater in the subgroups incubated with T 3 + steroid hormone, or with T 3 + gonadotropic hormone, than in the subgroups incubated with the same steroid or preparation of gonadotropic hormone without T 3' Differences between the first and second groups proved to be statistically significant (P < 0.011. The results suggest that T 3 influenced the maturational response of carp oocytes to some gonadotropic and steroid hormones.Introduction.
