A chromosome-level genome assembly of the striped catfish (Pangasianodon hypophthalmus)
<p>A<span> high-quality genome assembly of a mature female individual of striped catfish was generated by integration of short reads from an Illumina Hiseq Xten platform, long reads from a Nanopore platform, and Hi-C sequencing data. The Illumina short reads were sequenced at 60 X coverage, while the Nanopore long reads covered 85 X of the genome. This assembled genome is </span>742.6<span> Mb in length, with a contig N50 of 3.5 Mb and a scaffold N50 of 29.5 Mb, of which a total of 731.7 Mb reads (98.5%) were anchored on 30 pseudo-chromosomes. Among the totally searched 4,584 BUSCO groups in the popular actinopterygii_odb9 database, 4,279 (93.3%) BUSCO core genes were completely identified. </span></p>
Acute exposure of silver catfish (Rhamdia quelen) to chlorantraniliprole insecticide
<p>This study aimed to verify whether exposure to a commercial formulation of the chlorantraniliprole insecticide, which is used on rice crops, alters biochemical parameters in silver catfish (<em>Rhamdia quelen</em>). Fifty-four animals were distributed in six units per tank (n=6/repetition), in triplicate for each treatment: T1 - control (no insecticide), T2 (0.02 μg/L insecticide) and T3 (0.20 μg/L insecticide). Exposure lasted 24 or 96h, followed by a 96-h recovery in water free of pesticide. Results indicated biochemical changes in the levels of cortisol, glucose, lactate and plasma protein as well as few ionic alterations in the gills during exposure and recovery. The presence of chlorantraniliprole at 0.02 and 0.20 μg/L in water for acute exposure (sub-lethal) of silver catfish triggered osmoregulatory and/or biochemical imbalance under the tested conditions, and most of these alterations did not recover within 96h in clear water.</p>
