According to reports, the last comprehensive fish records from the Indus River were published in 1977. Although few recent studies have been conducted, they are limited to some confined localities, and hence there was a gap of comprehensive fish diversity analysis of the Indus River in Sindh province section. Therefore, the present investigation was performed to describe the fish fauna of the Indus River from its northern to its southern extremities. In order to establish fish diversity and distribution, the study was accomplished from June 2016 to May 2017 covering 8 sampling locations across the river. A total of 44 fish species, belonging to 35 genera, included in 18 families, and 9 orders were recorded. Family Cyprinidae was the most specious with 13 species followed by Bagridae and Cichlidae with 4 species each, and Siluridae with3 species. Alpha Diversity Indices study showed that the ichthyofauna diversity of the River was not high in comparison with previous studies. Shannon's index for the whole Indus River locations was 0.95 and the evenness index was 0.77. Sustained populations of exotic fish species were shown to have established in the Indus River.

The article discusses a study which show the food and feeding habit of a carp, Cirrhinus reba from Pakistan. Experimental fishes were gathered from fishponds of District Jacobabad, Sindh using a cast net with mesh size 12mm. Right after the collection, the fishes were preserved in 10% formalin to check further digestion of food. It notes that Cyanophyceae, Chlorophyceae and higher plants were found to be important food items for said fish next to debris. It suggests that the fish had maximum feeding intensity before noon to dusk and there was no tendency to change food items with the change in hour recorded in said fish.

The traditional polymerase chain reaction method was employed to obtain the complete mitochondrial genome ofChanna maruliusfrom Pakistan. The mitogenome was determined to be 16,569 bp in length. It contains 13 protein-coding genes, 2 rRNAs and 22 tRNAs. This is the first report on the complete mitogenome sequence ofC. marulius. [ABSTRACT FROM AUTHOR]

In the present study, the complete mitochondrial genome sequence ofBubo bubousing PCR amplification, sequencing and assembling has been obtained for the first time. The total length of the mitochondrial genome was 16,250  bp, with the base composition of 29.88% A, 34.16% C, 14.35% G, and 21.58% T. It contained 37 genes (2 ribosomal RNA genes, 13 protein-coding genes and 22 transfer RNA genes) and a major non-coding control region (D-loop region). The complete mitochondrial genome sequence ofBubo buboprovides an important data set for further investigation on the phylogenetic relationships within Strigiformes. [ABSTRACT FROM AUTHOR]

Complete mitochondrial genome of fresh water giant catfish,Wallago attu, was isolated by LA PCR (TakaRa LAtaq, Dalian, China); and sequenced by Sanger’s method to obtain the complete mitochondrial genome. The complete mitogenome was 15,639 bp in length and contains 13 typical vertebrate protein-coding genes, 2 rRNA and 22 tRNA genes. The whole genome base composition was estimated to be 31.17% A, 28.15% C, 15.55% G and 25.12% T. The complete mitochondrial genome of catfish,W. attu, provides the fundamental tools for genetic breeding. [ABSTRACT FROM AUTHOR]

Complete mitochondrial genome of fresh water catfishBagarius bagarius, was isolated by LA PCR (TakaRa LAtaq, Dalian, China); and sequenced by Sanger’s method to obtain the complete mitochondrial genome, which is listed Critically Endangered and Red Listed species. The complete mitogenome was 16,457 bp in length and contains 13 typical vertebrate protein-coding genes, 2 rRNA and 22 tRNA genes. The whole genome base composition was estimated to be 31.14% A, 27.72% C, 15.62% G and 25.50% T. The complete mitochondrial genome of fresh water catfish,B. bagariusprovides the basic genetic tools for breeding and conservation program to enhance aquaculture production. [ABSTRACT FROM AUTHOR]

The mitochondrial genome was amplified in two large overlapping fragments by long PCR and one gap PCR. The complete Northeastern China burbot mitogenome sequence (KC844053) is 16,575 bp in length. Similar to most vertebrata, the mitogenome has a set of 37 genes: including 13 protein-coding, 22 tRNA and 2 rRNA genes. More than 98% nucleotide sequence was simil to the reported individual.

The complete mitochondrial genome of Catfish,Rita rita, was isolated by LA PCR (TakaRa LAtaq, Dalian, China); and sequenced by Sanger’s method to obtain the complete mitochondrial genome, which is listed Critically Endangered and Red Listed species. The complete mitogenome was 16,449 bp in length and contains 13 typical vertebrate protein-coding genes, 2 rRNA and 22 tRNA genes. The whole genome base composition was estimated to be 33.40% A, 27.43% C, 14.26% G and 24.89% T. The complete mitochondrial genome of catfish,Rita ritaprovides the basis for genetic breeding and conservation studies. [ABSTRACT FROM PUBLISHER]
