Unraveling the Complete Mitochondrial Genome of (Purple Zebra Shrimp) (Crustacea: Decapoda) Provides Insights Into Its Phylogenetic Relationships and Gene Order Rearrangements.

Understanding the functions of mitochondrial genomes is crucial for studies related to the evolution of genomes, phylogenomics, and species identification. For the first time, complete mitogenome of a non-snapping shrimp has been successfully sequenced and characterized from Taiwan that belongs to the Decapoda order, Crustacea class, and Caridea infraorder. This study involved analysis of nucleotide composition, codon usage, gene ordering, evolutionary selection pressure, and comparative mitogenomics.

Plantago asiatica seed as a protective agent for mitigating metals toxicity on Penaeusvannamei.

Plantago asiatica seeds (PS) are commonly used as a medicinal plant. This study investigates the efficacy of PS against heavy metal toxicity in white shrimp (Penaeus vannamei). After feeding PS diet (5 g/kg) or basal diet (control group) for 7 days, shrimps were exposed to sublethal concentrations of heavy metals in seawater (As: 12 mg/L, Pb: 250 mg/L, Hg: 0.
