Gene editing techniques like CRISPR-Cas9 have enabled selective breeding for improved reproductive traits, creating fish strains with enhanced spawning frequency and fecundity. This has particularly benefited the local shrimp industry, increasing yearly production cycles.

Marker-Assisted Selection (MAS)

Marker-Assisted Selection (MAS) has enabled early and precise identification of brood stock with desirable traits such as faster growth, disease resistance, and better reproductive performance. MAS also accelerates breeding cycles, increases survival rates, enhances spawning success, and maintains genetic diversity, resulting in healthier, more efficient stock. Consequently, MAS reduces costs and time in breeding programs, leading to higher yields and more sustainable aquaculture production.

In aquaculture, the process of cryopreservation of gametes involves keeping fish eggs or sperm at extremely low temperatures, usually in liquid nitrogen (-196°C), for extended periods of time. Gametes are gathered using this technique, treated with cryoprotectants to shield the cells from freezing-related damage, and then stored in cryogenic vials. Oocyte cryopreservation is still more technically difficult than sperm cryopreservation, which is well-established and frequently used for species like carp, tilapia, and catfish. By guaranteeing a consistent supply of high-quality gametes throughout the year, this technology promotes genetic conservation, enables selective breeding, and supports hybridization programs.

Automated Spawning Induction Systems

Automated spawning induction systems integrate IoT sensors, AI vision, and precision hormone dosing to optimize breeding conditions in real-time.

Environmental Monitoring

IoT Sensors continuously track dissolved oxygen, pH, temperature.

AI-Powered Behavior Analysis

Camera systems use to monitor broodstock for spawning-ready behaviors like nest-building, chasing/nipping and color changes

Closed-Loop Hormone Delivery

Automated pumps helps to inject exact doses of hormones (e.g., Ovaprim) based on fish weight and stress levels

Why This Matters:

Boost Spawning Synchrony
Stress Reduction = More Broodstock Reuse
Hormone Savings
