Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Mazkur maqolada Farg`ona vodiysi kichik suv havzalari bo`lgan Oltiariqsoy va Janubiy farg’ona kanali irmoqlarida tarqalgan Kushakevich yalangbalig‘i – Iskandaria kuschakewitschi (herzenstein, 1890)ning morfobiologik kursatkichlarining qiyosiy tahlili natijalari keltirilgan. Suv havzalarida muhit sharoitining barqarorligi baliqlarning morfobiologik ko`rsatkichlarini o’zgarishiga olib kelmay, faqatgina baliqlarning umumiy o’g’irliklari va yon chizig`idagi poralar sonida, nisbatan farqlar borligi aniqlangan. Baliqlarning assimetriya ko’rsatkichi tahlili natijasiga ko’ra ularning bilaterial belgilari o`zgarishlarga uchramaganligini ko’rsatdi. Bu baliqlarning bir hil muhit sharoitida yashayotganligini va muhit omillarining salbiy ta’siri yo’qligini anglatadi.
