the systematics, morphology, distribution, biology, economic importance and conservation of the freshwater catfishes of iran are described, the species are illustrated, and a bibliography on these fishes is provided. there are four families with four genera and six species, one of which is an exotic; the family bagridae with one genus and species, mystus pelusius in the persian gulf, hormuz and...

This study supplemented the way of sex determination fish based on regression relationship some morphological indicators Mystus mysticetus. A total 425 specimens were collected by trawl nets at Cai Rang - Can Tho and Long Phu Soc Trang from January to July 2022. After collection, transferred laboratory determine their length (TL), standard (SL), eye diameter (ED), distance (DE), body height (BD...

Heat shock proteins play essential roles in basic cellular events. Spawning migration is a complex process, with significant structural and biochemical changes taking place in the adult gonad. To date, the molecular mechanisms underlying migration reproductive biology remain undetermined. In this regard, a full length HSP90AA1 comprising 2608 nucleotides from the anadromous fish Coilia nasus wa...

Coilia nasus is widely distributed in the Yangtze River, the coastal waters of China, Korea and the Ariake Sound of Japan. Several ecotypes exist and this provides a useful model for the study of comparative diversity between molecular markers. Here we analyze and compare the nucleotide sequences between single-copy ribosomal protein S7 gene intron 1 (rpS7) and multiple-copy ribosomal internal ...

In the protection of migratory species, Coilia nasus has always been a research topic very high interest in various countries because economic value and serious decline resources. this study, C. were collected from Shengsi Sea area, Yangtze River estuary, Taizhou section Poyang Lake. By using 2b-RAD simplified genome sequencing technology, 63,110 SNP sites screened, genetic diversity each popul...
