Genetic Characteristics and Phylogenetic Relationships of 18 Anchovy Species Based on Mitochondrial Genomes in the Seas Around China.

ABSTRACT: The anchovy family (Engraulidae) holds significant economic and ecological value in seas around China, playing a crucial role in fisheries and marine ecosystems in these regions. This study analyzed the complete mitochondrial genome data of 18 Engraulidae species from seas around China, integrating molecular evidence to systematically investigate mitochondrial genome structure, codon usage patterns, and phylogenetic relationships within the family. The mitochondrial genomes of Engraulidae exhibited a highly conserved structure, characterized by significant A + T richness and variable control region lengths. Codon usage analysis in seven Thryssa species revealed that base composition, particularly GC content at the third codon position (GC3s), along with purifying selection, jointly
