Cobia Growth and Gene Expression Under Blue and Green Light

A four-week study investigated the effect of blue and green light wavelengths on juvenile cobia (Rachycentron canadum). The dataset, authored by Yafan Zhu and last updated in 2026, includes results on body weight, specific growth rate, and transcript levels of genes related to appetite and lipid synthesis. It highlights the non-invasive application of spectral optimization in aquaculture.

Use Cases

• Modeling fish growth performance based on exposure to specific light wavelengths.
• Analyzing gene expression patterns for appetite-regulating peptides like neuropeptide Y (npy) and pro-opiomelanocortin (pomc).
• Studying the relationship between extraretinal photoreception and growth hormone receptor (ghr) transcript levels.
• Investigating the impact of light spectra on lipogenesis via fatty acid synthase (fas) expression.

Strengths

• Specific growth metrics are reported, including a 27.6% increase in body weight under blue light.
• Gene expression data targets key regulatory pathways for appetite and lipid synthesis.
• Clear experimental design with defined light wavelengths (466 nm blue, 518 nm green) and a four-week duration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (15.5 KB), indicating limited scope.
