| چکیده | ||
| پاروپایانی نظیر Acartia tonsa از نظر آبزیپروری بدلیل دارا بودن میزان همآوری زیاد، زمان تجدید نسل کوتاه و نیز مقاومت نسبت به تغییرات شوری و دما دارای اهمیت قابل توجهی اند. لذا تولید انبوه A. tonsa جهت استفاده از آن به عنوان غذای زنده در صنعت آبزیپروری از اهداف این تحقیق بوده است. در این مطالعه نقش عوامل اکولوژیک شوری و دما در چرخه زندگی گونة A. tonsa دریای خزر در شرایط آزمایشگاهی در سه تیمار دمایی(1±29، 1±27 و1±25 درجهسانتیگراد) و دو تیمار شوری(ppt 12 و 17) طی مدت زمان 60 روز مورد بررسی قرار گرفت. این گونه توسط تورپلانکتون با اندازه چشمه100 میکرون از عمق تا 10 متر حوزه جنوبی دریای خزر (منطقه خزر آباد) جمع آوری شد. بررسی چرخة زیستی این زئوپلانکتون نشان داد که این گونه در طی 10-8 روز بالغ میشود. بر اساس نتایج به دست آمده اختلافات معنیداری در تعداد موجودات در مراحل ناپلیوسی و کوپه پودیت در شوری ها و درجه حرارت های مختلف مشاهده گردید (05/0>P). بیشترین میزان تولید تخم، و تبدیل آنها به مرحلة ناپلیوس در دمای 29 درجهسانتیگراد با شوری ppt17 بود. بیشترین میزان بازماندگی این گونه نیز در همین شوری ثبت گردید. این تحقیق نشان داده است که در شرایط آزمایشگاهی می توان تولید انبوه از گونه A. tonsaباشوری آب دریای خزر تهیه نمود که میزان تولید مثل آن در حدود 8-1 عدد تخم در روز بازای هر جانور ماده است که قابل مقایسه با تولید مثل طبیعی آن در دریا با حدود 50-11 عدد تخم در روز می باشد. | ||

| چکیده [English] | ||
| The present study carried out an in vitro experiment on effects of salinity and temperature on Acartia tonsa life cycle from Caspian Sea. During the experiment, temperature and salinity ranged 25, 27, 29 ± 1 °C and 12‰ and 17‰, respectively within a period of 60 days. Spawning rate was measured using mesh size of 100 µ planktonic net from surface to 10 m depth. Early results show that nauplii arrive to adult stage during 8-10 days. Significant differences in nauplii and copepodites stage were found also in different salinities and temperatures. High survival and spawning rate were also found in 17 ‰ and 29 °C (P < 0.05). Our investigations showed that in in vitro reproduction of A. tonsa in the Caspian Sea water with 1-8 eggs per each female may be feasible compared to 17-50 eggs in natural conditions. | ||
