The sturgeon (Acipenseriformes) is an important farmed species because of its economical value. However, neither gene transfer nor gene editing techniques have been established in sturgeon for molecular breeding and gene functional study until now. In this study, we accomplished gene transfer and gene editing in sterlet (Acipenser ruthenus), which has the shortest sexual maturation period of st...

OBJECTIVE To determine a levothyroxine (T4) dose recommendation for the treatment of autoimmune thyroiditis (AIT)-induced hypothyroidism. METHODS T4 doses in 75 children and adolescents with newly diagnosed AIT were prospectively collected and compared to T4 doses of patients with congenital hypothyroidism (CH, n=22). RESULTS Sixty-four patients with AIT and 22 patients with CH were include...

The effects of starvation and subsequent re-feeding on compensatory growth performance, blood serum metabolites and IGF-ImRNA expression in liver and muscle were investigated in juvenile Persian sturgeon. Growth indices including body weight, SGR, CF, and HSI significantly decreased after starvation. However, after re-feeding sturgeons that were starved for 1 week reached the same weight as the...

high mortality and labor costs are associated with first-feeding sturgeon culture, particularly during the period of dietary transition from live to formulated feed. therefore we investigated the effects of various feeding treatments on the survival and growth of the persian sturgeon ( acipenser persicus ) larvae during a 20-day culture period. three replicate groups (250 fish/replicate) of fir...

in poland the conservation program of atlantic sturgeon acipenser oxyrinchus is conducted during over 10 years by inland fisheries institute in olsztyn, poland. material of a. oxyrinchus is annually transported from canada to poland and the broodstock of this species is created. part of imported fish material is breed and released into local rivers e.g. drweca river, vistula river. all the impo...

rearing conditions such as density, temperature, water quality, and frequency of feeding are among the most important factors affecting fish growth in aquaculture. therefore, this study was done to evaluate effects of interaction between temperature and feeding frequency on the growth of juveniles caspian roach weighting approximately 0.5 ± 0.05 g during 45 days. juvenile fish were reared at fo...

A consequence of increasing litter size in sheep is that a portion of the lambs have to be reared artificially. Detailed information about the pattern of milk consumption of artificially reared lambs would help improve their management. The purpose of this study is to describe the individual and group feeding behaviour of 94 Romane artificially reared lambs from 5 to 28 days of age using an ele...
