This study compared the hematological characteristics of diploid and triploid of jundia, Rhamdia quelen juveniles, an important freshwater fish cultured in south Brazil. Hematological morphometry of erythrocytes were determined in blood smears under a light microscope. The blood was used to measure the number of red blood cells (RBC) with a hemocytometer Neubauer chamber, and the numbers of whi...

A new miniaturized species of the trichomycterid genus Ammoglanis is described from the Rio Orinoco basin in Venezuela. It is distinguished from its only congener, A. diaphanus, by: a banded color pattern formed by internal chromatophores; 5 or 6 pectoral-fin rays (7 in A. diaphanus), 5/5 principal caudal-fin rays (6/6 in A. diaphanus), ii+6 dorsal-fin rays (iii+6+i in A. diaphanus), 30 or 31 v...

The monotypic genus Tanganikallabes, endemic to Lake Tanganyika, is a poorly known member of the family Clariidae. Examination of 142 specimens housed in museum collections has revealed the presence of at least two additional species in this genus. Tanganikallabes alboperca sp. nov. is distinguished from all congeners by the length of its pelvic fins, the presence of a depigmented vertical bar ...

This data-set complements our paper entitled "The use of transcriptomic next-generation sequencing data to assembly mitochondrial genomes of Ancistrus spp. (Loricariidae)" [6]. Here, we present the nucleotide sequences of each transcript used for mitogenomes assembly, as well as tables presenting the location of each transcript in the mitogenomes; the frequency, location and codon position of t...
