چکیده

عملکرد مولدین میگوی سفید غربی تحت تاثیر شرایط محیطی مختلف، نوع تغذیه، اندازه و مکان پرورش متفاوت می­باشد. در مطالعه حاضر عملکرد تولید مثلی مولدین میگوی سفید غربی در دو سیستم پرورشی معمولی ( تعویض آب) و تعویض آب محدود مورد بررسی قرار گرفت. مولدین ماده با میانگین وزن 8/6 ± 6/38 گرم از مرکز تکثیر آبزی پرور چابهار واقع در کنارک تهیه و در مخازن 2000 لیتری مورد آزمایش قرار گرفتند. دو تیمار در سه تکرار در قالب طرح کاملا تصادفی برای مطالعه حاضر در نظر گرفته شد. شامل: تیمار کنترل (سیستم پرورش معمولی) که روزانه 90 درصد آب مخازن تعویض و تیمار با تعویض آب محدود (روزانه 2 تا 3 درصد) از کف مخازن تعویض آب صورت می گرفت. نتایج نشان داد تفاوت معنی­داری در عملکرد رشد مولدین بین دو سیستم پرورش وجود ندارد (05/0p > )، اما ضریب بقاء در سیستم پرورش با تعویض آب محدود (57/97 درصد) بالاتر بود. تعداد تخم در هر مرحله تخم­ریزی برای میگوهای تحت سیستم پرورشی معمولی و تعویض آب محدود به ترتیب 47500 و 60800 بدست آمد که اختلاف معنی­داری بود (05/0 >p ). همچنین تعداد تخم تبدیل شده به ناپلیوس در سیستم تعویض آب محدود نسبت به سیستم معمولی بیشتر بدست آمد. بطور کلی مطالعه حاضر نشان داد عملکرد تولید مثلی مولدین میگوی سفید غربی در سیستم پرورشی با تعویض آب محدود نسبت به سیستم معمولی بهتر می­باشد.

چکیده [English]

The performance of Pacific white shrimp broodstocks is affected by several factors including different environmental conditions, feeding type, size, and the cultivation site. In the present study, two different reproduction systems were used to investigate the reproductive performance of Pacific white shrimp broodstocks: conventional (water exchange) and limited water exchange Female broodstocks having an average weight of 38.6 ± 6.8g were obtained from Chabahar Reproduction Center located in Konarak and experimented in 2000-liter tanks. Two treatments in three replications in a completely randomized design were considered for the current research, including: control group (conventional rearing system) in which 90% of the water was replaced and limited water exchange treatment in which 2 to 3% of the water was exchanged daily. The results of this study showed no significant difference in the growth performance of broodstocks between two cultivation systems (p > 0.05), but the survival rate in the limited water exchange system were measured higher (97.57%). Moreover, the number of eggs in each spawning stage for shrimps under conventional farming system and limited water exchange 47,500 and 60,800 were obtained, respectively, a significant difference (p < 0.05). Furthermore, the number of shrimp eggs in each spawning stage varied significantly in the conventional system and in the limited water exchange treatment, with 49,300 and 60,800 eggs, respectively (p <0.05). A higher number of eggs converted to nauplius by the limited water exchange system than by the conventional system. In general, this study found that the reproductive performance of Pacific white shrimp broodstocks in the system with limited exchange of water is better than the conventional system.
