Chromosome assembly of Collichthys lucidus, a fish of Sciaenidae with a multiple sex chromosome system

Collichthys lucidus ( C . lucidus ) is a commercially important marine fish species distributed in coastal regions of East Asia with the X 1 X 1 X 2 X 2 /X 1 X 2 Y multiple sex chromosome system. The karyotype for female C . lucidus is 2n = 48, while 2n = 47 for male ones. Therefore, C . lucidus is also an excellent model to investigate teleost sex-determination and sex chromosome evolution. We reported the first chromosome genome assembly of C...
