Fish Gene Editing Joint Bioinformatic Technology Platform
BioVenic has introduced genome-wide gene knockout methods for scientific research projects aiming to screen for new functional information in fish. We generate guide RNA (gRNA) libraries to target each gene in the organism for editing. We then utilize gene editing techniques and statistical analysis to investigate the role of the target gene in the phenotype under study, as well as the functions of other potential genes in the organism. The customized service for constructing high-throughput libraries that infect single cells supports customers in genome-wide screening of phenotypes or disease targets of interest. It promotes the integration of large-scale genetic screens and provides information on the biological basis of disease resistance.
Precision Breeding in Aquatic Species
The emergence of gene editing technology has accelerated the genome editing of aquaculture species. The editing system is simple, efficient, with a low off-target tendency, and capable of producing long fragment deletions. With the assistance of gene editing tools, researchers have conducted multidirectional gene function and precision breeding research on various major aquaculture species. Through in-depth exploration of the growth, disease resistance, reproduction, sterility, and coloration patterns of fish, we can understand the scientific foundation for genetic enhancement and precision breeding.

Growth
Growth efficiency is the most common goal for precision breeding and genetic improvement in fish projects. Technological tools such as transgenics and genome editing are utilized to investigate factors influencing economic traits like growth rate, growth status, and feed utilization by targeting genes associated with phenotypes. At the same time, increasing per capita productivity by preventing cannibalism is also a unique solution in the precision fish breeding strategy. Enhancing the future sustainability of aquaculture by boosting productivity through genome editing. -
Fish Oil Production
Fish oil is a beneficial fatty acid for human health and serves as a dietary supplement to meet nutritional requirements. Gene-level genetic modification tools, combined with sequencing technology, allow researchers to gradually unravel the pathways of fish oil production and fish fatty acid metabolism. -
Disease Resistance
Disease resistance is another crucial economic trait in aquaculture and commercial production. Genetic enhancement of disease resistance continues to be a top priority in breeding programs. Precision breeding has been studied to enhance immunity and resistance to common diseases in fish. At the same time, genome-level modification and manipulation support the exploration of the principles of pathogenic mechanisms and uncover the genetic codes behind complex metabolic pathways and corresponding phenotypes. -
Sterility and Reproductive Confinement
The escape of non-native fish from aquaculture facilities can have unpredictable environmental, ecological, and genetic impacts. Creating sterile aquatic animals through precision breeding reduces risks and prevents genetic introgression from wild populations. This process protects genetic integrity and helps avoid the negative production consequences of premature maturation. Sequencing, transgenic, and gene-editing technologies have significantly advanced our understanding of the steroidogenic pathway, hormonal regulation, and the molecular mechanisms of sex determination and differentiation in fish.

Frequently Asked Questions
What high-throughput library services do you provide for aquatic gene function screening?
We supply customized genome-wide gene libraries and targeted guide sequence libraries for fish research. These high-throughput libraries support large-scale phenotype screening, enabling systematic mining of key genes related to fish growth, disease resistance, fatty acid metabolism and reproductive traits, and laying data foundations for directional genetic improvement.
What core economic breeding traits can your precision fish breeding technology optimize?
Our multi-dimensional genetic modification and analytical platform targets four major aquaculture breeding goals: accelerating growth and improving feed conversion efficiency, enhancing fish disease resistance and innate immunity, regulating fatty acid synthesis to boost fish oil nutritional value, and inducing fish sterility to avoid ecological risks caused by escaped farmed fish.
What technical optimizations do you adopt to solve common defects in aquatic genome manipulation?
We optimize the whole embryo operation workflow to lower chimerism and off-target mutation rates, accurately grasp the optimal developmental window of fertilized fish embryos for target sequence delivery, and match stable aquatic cell line resources to support repeated verification of gene function and phenotypic changes.
What full experimental workflow do you provide for aquatic genome manipulation projects?
The complete service covers genome database screening and target gene selection, probe design and off-target risk assessment, synthetic oligo preparation, embryo microinjection, mutant fish breeding and genotypic identification, plus the construction of gamete cryobanks for long-term preservation of modified strains.
How does sterile fish breeding help aquaculture and ecological protection?
Artificially induced sterility prevents escaped farmed fish from interbreeding with wild populations, avoiding wild germplasm pollution and genetic introgression. It also eliminates the production loss caused by early sexual maturation of fish, improving the overall growth performance and economic output of farmed aquatic products.
