Fish Short Term Reproduction Assay

Fish Short Term Reproduction Assay

The fish short-term reproduction assay (FSTRA) is an in vivo screen used to assess potential interactions with the fish endocrine system. fish short-term reproduction assays are short assays that provide information on the effects of chemicals on fish reproduction, which may be caused by endocrine-disrupting effects. After a 21-day exposure period, vitellogenin (VTG) and secondary sexual characteristics were measured in males and females. Egg production and fertilization rates are also monitored daily throughout the testing period.

The scientists of CD BioSciences provide information on the effects of chemicals on fish reproduction, which may be caused by endocrine-disrupting effects. Our services extend to providing bespoke study designs to meet the specific needs of our clients. From planning to the final report, we keep our clients informed every step of the way through the short-term fish breeding trial process, ensuring their trials are successful. We also provide consulting services to guide clients through the regulatory requirements for their chemical products.

Our Services

As a leading company in this field, CD BioSciences provides comprehensive characterization services to FSTRA. Our laboratories are also well-equipped to handle complex assays and provide accurate analyses. Our services are listed as follows, but are not limited to:

  • Fecundity
    Our scientists monitor fish fertility daily, watching for spawning and spawning.
  • Evaluation of gonadal histopathology
    During the test, we will preserve the gonads of the fish and evaluate the reproductive fitness of the fish.
  • Egg quality and viability analysis
    To assess the egg quality, we will perform Raman spectroscopy on fish eggs. Classification results from the yolk will be obtained using principal component analysis (PCA) and linear discrimination analysis (LDA).
  • Sperm motility assessment
  • Gene expression analysis
