چکیده

این مطالعه در قالب پروژه بررسی وضعیت تولیدمثلی ماهیان اقتصادی تالاب انزلی و از فروردین تا اسفند 1395 صورت گرفت و ماهیان با استفاده از دستگاه صید الکتریکی از 4 منطقه  تالاب انزلی صید شدند. وزن بدن ماهیان سیم نما نر بالغ (173 عدد) 1/08 تا 33/22 با میانگین 4/06±7/12 گرم و در ماهیان ماده بالغ (271 عدد) 0/71 تا 59/9 با میانگین 9/16±12/66 گرم تعیین شد. هم چنین طول کل نرهای بالغ 45/5 تا 136 با میانگین 14/03±80/02 میلی متر و در ماده های بالغ 41/3 تا 166 با میانگین 22/06±92/81 میلی­ متر اندازه ­گیری شد. بالغین نر (57 عدد) در گروه سنی 2 تا 11 سال و بالغین ماده (130 عدد) 1 تا 15 سال قرار داشتند. نرها و ماده ­های بالغ سیم نما به ترتیب 38/96 و 61/04 درصد جمعیت بالغین را تشکیل دادند. میزان هم آوری مطلق این ماهی در تالاب انزلی (16عدد) 3805 تا 11483 با میانگین 1997/89±6898/1 عدد تخمک و قطر متوسط تخمک 0/1±0/9 میلی متر به دست آمد. درصد شاخص گنادی ماهیان ماده بالغ در ماه ­های مختلف بین 1/00 (مرداد ماه) تا 13/7 (فروردین) با میانگین 7/08±6/54 متغیر بود. زمان تخم ریزی این ماهی در تالاب انزلی براساس شاخص گنادی و مراحل رسیدگی­ جنسی ماهیان ماده بالغ، فروردین تا تیر­ ماه تعیین شد. اگر چه سیم نما ارزش اقتصادی ندارد اما این گونه در تالاب انزلی برای مصارفی صید می ­شود که با توجه به فصل تکثیر آن از صید بی رویه آن خودداری گردد.

چکیده [English]

The study carried out in reproduction status project of commercial fishes of Anzali wetland from April 2016 until March 2017 and samples were caught using electroshocker in different points of studied area. The studied adult males (n=173) weight varied between 1.08 and 33.22 with an average of 7.12±4.06g and adult females (n=271) between 0.71 and 59.9 with an average of 12.66±9.16g. Total length were measured between 45.5 and 136 with an average of 80.02±14.03mm in adult males and between 41.3 and 166 with an average of 92.81±22.06mm in adult females, too. Age composition was from 2 to 11 and 1 to 15 years old for adult males(n=57) and females (n=130), respectively. Adult males and females formed 38.96% and 61.04% of adults. Monthly average of gonado-somatic index was determined 1% in August and 13.7% in April with an annual average of 6.54±7.08%for adult females. Spawning period of the fish species was determined on basis of gonado-somatic index and composition of gonad maturity stages of adult females from April to July. Absolute fecundity of studied fish (n=16) was calculated 3805-11483 with an average of 6898.1±1997.89 eggs and average of egg diameters was 0.9±0.1 mm. Although this fish has no economic value but this species is caught in Anzali wetland for consumption. Due to its Reproduction season, its overfishing should be avoided.
