Commercial Aquaculture Technician

While automated acoustic biomass counters, underwater camera feeding telemetry, and satellite water quality monitors assist in aquaculture operations, the physical management of open water fish cages remains shielded from automation. Boating into stormy lake or ocean waters during severe weather to secure mooring lines, diving to inspect submerged net cages for tearing from predators, physically grading thousands of live fish to separate size cohorts, and administering therapeutic bath treatments for parasitic outbreaks demand hands on physical seamanship, biological intuition, and manual dexterity.

Across the Blue Economy corridors of Lake Victoria and the Indian Ocean coastline in East Africa, cage mariculture technicians are transforming food security and sustainable fisheries. Working in collaboration with the Kenya Marine and Fisheries Research Institute KMFRI and the State Department for Blue Economy and Fisheries, these commercial aquaculture specialists provide high yield, environmentally sustainable fish production that reduces pressure on wild ocean fish stocks and creates vibrant rural aquatic enterprises.

A typical day involves taking early morning boat runs to offshore cages, measuring dissolved oxygen levels across twelve pens, inspecting feed response, mending a torn predator net, and coordinating a five ton harvest for refrigerated transport. Typical daily tasks encompass: Powering up the workboat and navigating to floating cage clusters located one kilometer offshore in the morning mist.; Lowering digital multiparameter probes to measure dissolved oxygen and temperature at two meter and five meter depths.; Operating automated pellet blowers while closely observing fish feeding vigor to calculate daily biomass feed intake.. You coordinate closely with cross functional colleagues to align on immediate deliverables, double checking equipment readiness and standard operating protocols.

In the afternoon, you execute core deliverables, consult with cross functional colleagues, document operational outcomes, and ensure that all equipment and handover notes are fully updated before completing the shift. Before completing the shift, you reconcile physical logs, review operational checklists with the oncoming team, archive incident reports, and brief project supervisors on task completion.

Commercial Aquaculture Cage Mariculture Technicians manage, operate, monitor, and maintain open water floating marine and lacustrine cage aquaculture systems, fish health management programs, automated feeding systems, and harvesting operations for commercial finfish species such as tilapia, cobia, and sea bass. Operating in ocean bays, coastal lagoons, and expansive inland lakes like Lake Victoria, they assemble floating high density polyethylene HDPE circular cages, inspect subsea predator netting with underwater cameras, monitor water dissolved oxygen and salinity parameters, formulate nutritional feeding regimes, and execute biosecure harvesting and cold chain transport.

Core responsibilities include assemble, moor, inspect, and maintain floating circular hdpe aquaculture cages, mooring grids, and predator exclusion netting., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Bureau of Standards KEBS, National Construction Authority NCA, KenGen Kenya Electricity Generating Company, Safaricom PLC, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
