[ 1 ] - Association between growth hormone gene polymorphisms and growth traits in Cyprinus carpio from the Caspian Sea
Growth hormone (GH) is the most important hormone that controls somatic cell growth and the syntheses of protein, fat, and carbohydrates. This study was to identify gene polymorphism of GH-1 using PCR- single strand conformation polymorphism (SSCP) technique and its association with growth traits including condition factor (CF), body weight (BW) and total length (TL) in common carp (Cyprinus ca...
[ 2 ] - تأثیر نوع محیط کشت برروی رشد و میزان کلروفیل ریزجلبک Nannochloropsis oculata در فتوبیوراکتور لوله ای
در مطالعه ی حاضر، رشد و میزان کلروفیل a ریزجلبک Nannochlorpsis oculata ، با استفاده از دو نوع محیط کشت گیلارد و والن در دو دوره ی 15 روزه بررسی گردید. تراکم سلولی، موجودی کلروفیل a و وزن خشک ریزجلبک در هر دو محیط، روزانه با 3 تکرار اندازه گیری شد. تراکم سلولی و موجودی کلروفیل a در ریزجلبک رشدیافته در محیط والن به ترتیب در روز 3 تا 10 و 2 تا 15 (به جز روز 14) بیشتر از محیط گیلارد بود (P < 0.05) ...
[ 3 ] - Association between growth hormone gene polymorphisms and growth traits in wild common carp, Cyprinus carpio from the Caspian Sea
Growth hormone (GH) is the most important hormone that controls somatic cell growth and syntheses of protein, fat, and carbohydrates. This study was conducted to identify gene polymorphism of GH-1 using PCR -single strand conformation polymorphism (SSCP) technique and its association with growth traits including condition factor (CF), body weight (BW) and total length (TL) in common carp (Cypr...
[ 4 ] - Integrated effects of photoperiod and light intensity on some reproductive parameters of Artemia parthenogenetica during consecutive weeks in semi-intensive culture system
This study investigated the integrated effects of two photoperiods (16:08 and 08:16 h) along with three light intensities (3000, 15000 and 50000 lux) on some reproductive parameters and broodstock survival rates of Artemia parthenogenetica in six treatments in a completely randomized factorial design in culture system until death. Two-way ANOVA analysis revealed significant differences in total...
[ 5 ] - Effects of rearing density on physicochemical properties of water, growth parameters, survival, and body composition of Caspian kutum (Rutilus frisii)
Proper storage density affects the growth and rearing of fish. This experiment was carried out to investigate the effects of rearing densities on the growth and carcass composition of Caspian kutum (Rutilus frisii) fry and physicochemical factors of farming water. Fish were examined in five rearing densities (5, 10, 15, 20, and 25 fish/60 L of water) with three replications, and fed based on 8%...
