The complete mitogenome of Pareuchiloglanis sichuanensis (Siluriformes: Sisoridae) [PDF]

Mitochondrial DNA Part B, 2021
Pareuchiloglanis sichuanensis is an endemic fish species in the upper reaches of the Yangtze River. In the present study, the complete mitochondrial genome of P. sichuanensis was analyzed. The mitochondrial genome, consisting of 16,774 base pairs (bp), included 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a non-coding control region.

Sperm of Doradidae (Teleostei: Siluriformes)

Tissue and Cell, 2011
Spermatic characteristics were studied in 10 species representing several distinct groups within the catfish family Doradidae. Interestingly, different types of spermatogenesis, spermiogenesis and spermatozoa are correlated with intrafamilial groups previously proposed for Doradidae.
