In order to distinguish between 'true' system variability and sampling variability we simulated the development of the bream population, using estimates for population structure and gro...

این تحقیق با هدف مطالعه الگوی رشد و تکوین آنزیم آلفا آمیلاز در لارو ماهی سیم معمولی (Abramis brama) از زمان    تخم­گشایی تا 60 روز پس از آن در مجتمع تکثیر و پرورش و بازسازی ذخایر شهید انصاری (گیلان، رشت) به اجرا درآمد. نتایج نشان داد که در زمان تخم­گشایی لاروها دارای وزن­تر اولیه 03/0 ± 65/0 میلی­گرم و طول کل 24/0 ± 66/4 میلی­متر بودند. الگـوی رشد در ماهی سیـم معمولی درطی روند تکـوین اولـیه تا ...
