study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...
during the growing seasons of 2009 and 2010, same tomato fields throughout marvdasht were visited and 96 isolates of fusarium spp. were collected from root, crown and stem of diseased tomato plants. isolates were identified as based on morphological characteristics. they were divided into four species namely: fusarium solani, f. pseudoanthophilum, f. oxysporum and f. equiseti. these species,...
گونههای سرخرطومی Larinus spp. تولیدکنندۀ مان روی گیاهان دارویی تیرۀ Asteraceae فعالیت میکنند. در این تحقیق ویژگیهای چرخۀ زیستی سرخرطومی Larinus trehalanus G&Sh بهعنوان یکگونۀ جدید روی گیاه دارویی CousiniastocksiiWinklerدر منطقۀ کرمان در شرایط صحرایی طی سالهای 1389 و 1390 بررسی شد. این سرخرطومی بهصورت حشرۀ کامل زمستانگذرانی میکند و در منطقۀ کرمان یک نسل در سال دارد. حشرات ماده تخمهای...
Effects of artificial diets on growth, spawning performance, egg and larval biochemical compositions and quality of Acanthopagrus latus in the Persian Gulf were studied. Nine diets representing a combination of three protein levels (40, 50 and 60%) and three energy levels (22.5, 23.5 and 24.5 MJ GE/Kg) were tested in triplicates. Each tank was stocked with 10 fish with a sex ratio of 1:1 and wi...
A 30-day study was carried out to determine the influence of different weaning strategies (WS) on growth and survival rates, stress resistance, digestive enzyme activities whole body fatty acid profiles in yellowfin seabream (Acanthopagrus latus) larvae. Thus, eight WS were designed by combining live foods (LF) (rotifers Artemia) a microdiet (MD) (Gemma Micro™, Skretting). In control group (100...
Seasonal changes of the thyroid gland structure and hormones secretion was examined in yellowfin seabream (Acanthopagrus latus) in the northwest of Persian Gulf (Musa creek). Thyroid gland composed of follicles scattered around the ventral aorta, near the gills. Follicular cells varied according to secretion of the gland during warm and cold seasons. Thyroid hormones (Triidothyronine [T3] and ...
The total lipid content and composition of fatty acids of the liver and muscles of wild and cultured male and female Acanthopagrus latus were determined by gas-liquid chromatography. There were quantitative differences between individual fatty acids in the tissues investigated depending on sex and location. In all the samples studied, sex and location considered, the principle saturated fatty a...
Because weevils are used as biocontrol agents against thistles, it is important to document and understand host shifts and the evolution of host-specificity in these insects. Furthermore, such host shifts are of fundamental interest to mechanisms of speciation. The mediterranean weevil Larinus cynarae normally parasitizes either one of two thistle genera, Onopordum and Cynara, being locally mon...
