Reference genome of the Monkeyface Prickleback, Cebidichthys violaceus

Area of Science:

• Marine Biology
• Genomics
• Conservation Science

Background:

• Pricklebacks (Family Stichaeidae) are cold-temperate marine fishes predominantly found in the North Pacific.
• Understanding marine organism phylogeography is crucial for effective conservation strategies in regions like California.

Purpose of the Study:

• To sequence and assemble the genome of the Monkeyface Prickleback (Cebidichthys violaceus) as a genomic model.
• To establish a reference genome for the California Conservation Genomics Project (CCGP).
• To inform the design of marine protected areas using future population genomic data and dispersal models.

Main Methods:

• Whole genome sequencing of Cebidichthys violaceus.
• Genome assembly and quality assessment (contig N50, scaffold N50, BUSCO completeness).

Main Results:

• A near-chromosome level genome assembly for C. violaceus was generated (genome size = 575.6 Mb).
• Assembly quality metrics include contig N50 = 1 Mb, scaffold N50 = 16.4 Mb, and 93.2% BUSCO completeness.
• The genome serves as a foundational resource for the CCGP.

Conclusions:

• The C. violaceus genome provides a valuable reference for future population genomic studies.
• This research will enhance understanding of marine species population structure and California's marine ecosystems.
• Genomic data will contribute to evaluating the efficacy of marine protected areas as a conservation tool.
