Marine Drone Aquaculture Solutions

Transform your fish farm operations with Lochain Marine's professional underwater drones. Replace risky and expensive manual inspections with safe, efficient and 24/7 available underwater monitoring technology.

Aquaculture Industry Challenges

Aquaculture is one of the most important agricultural production sectors, involving the controlled breeding, rearing and harvesting of fish, shellfish, seaweed and other aquatic species in artificial or natural environments. Fish farm owners need to regularly inspect fishing nets and cages for damage, monitor the growth and health of cultured animals, and ensure water quality meets standards. However, traditional manual inspection methods are facing unprecedented challenges.
Net Cage Inspection with Underwater Drones

💰 High Inspection Costs

Commercial diving teams are extremely expensive and require advance booking. You cannot respond to emergencies in a timely manner, and the inflexible working hours lead to production delays.

 Fish Health & Stock Monitoring ROVs

⏱️ Limited Diving Time

Frogmen can only work for about 30 minutes per dive, and can only perform 2-3 dives per day. This low efficiency makes large-scale cage inspections a time-consuming and labor-intensive task.

Net Cage Inspection with Underwater Drones

⚠️ Severe Safety Risks

Manual inspections have limited diving depth, and divers face life-threatening risks such as net entanglement, strong currents and marine predators like sharks. Accidents can cause huge losses to enterprises.

Key Application Scenarios

Lochain Marine underwater drones cover all core inspection and maintenance needs in aquaculture operations
Fish Health & Stock Monitoring ROVs

Regular Cage Inspection

Water Quality Testing

Real-time monitoring of pH, dissolved oxygen, salinity and other key water quality parameters

underwater fish monitoring

Debris Salvage

Salvage dead fish, garbage and other debris in cages to maintain a clean growing environment

Aquaculture Infrastructure Survey

Aquatic Growth Observation

Regular observation of fish growth and health status to optimize feeding and management strategies

Benefits of ROVs for Marine Ranching

Cage Net Cleaning

Remove biofouling, algae and barnacles from cage nets. Unclean nets block water flow, cause oxygen depletion, increase disease risk and raise cage maintenance costs.

Our Solution Values

Lochain Marine ROVs bring comprehensive benefits to your aquaculture business

Monitor Aquatic Animal Growth

Regular observation and inspection help fish farm owners record the growth process of cultured animals accurately and adjust feeding and management measures in a timely manner.

Comprehensive Water Quality Check

Monitor and record water temperature, pH, salinity and dissolved oxygen levels in real time to ensure the water environment is always suitable for aquaculture growth.

Improve Cage Environment

Quickly remove dead fish, food residues and potentially harmful substances from cages to provide a healthy and clean growth environment for cultured animals.

Guarantee Production Value

Conduct regular cage safety inspections in advance to avoid huge economic losses caused by cage damage and fish escape, ensuring stable production output.

Genetic Isolation Protection

In some countries, our solutions help implement genetic isolation measures to avoid genetic contamination of wild species by farmed species, complying with local regulations.

Significant Cost Savings

Support 24/7 monitoring at any time, greatly reducing labor costs and eliminating the high expenses of commercial diving teams. One-time investment, long-term returns.

Easy to Operate

Designed for non-professionals, single-person operation is possible. No complex training required, and your staff can master the operation in just a few hours.

Extend Cage Service Life

Regular net cleaning prevents excessive biofouling accumulation, reduces cage structural load and corrosion, and extends the service life of aquaculture facilities by 30%.
