Fishing Netting in Kenya: Types, Materials, Applications, and How to Choose the Right Netting Solution

Fishing netting sits at the core of Kenya’s fisheries, aquaculture, and marine operations. From large-scale capture fisheries on Lake Victoria to cage-based tilapia farming, coastal marine fishing, and safety installations on boats and waterfront structures, netting is not a simple accessory—it is a structural system that directly determines efficiency, durability, and profitability.

Selecting the wrong netting type, mesh size, or material results in lost catch, juvenile bycatch, structural failure, higher maintenance costs, and shortened replacement cycles. Conversely, choosing correctly specified netting improves harvest efficiency, protects stock, supports sustainability, and reduces long-term operating costs.

This guide provides a technical, decision-focused breakdown of fishing netting in Kenya, including net types, material science, specifications, real-world applications, cost expectations, and supplier considerations. It is written for commercial fishers, aquaculture operators, cooperatives, NGOs, and marine contractors, with practical insights grounded in Kenyan water conditions.

Understanding Fishing Netting in the Kenyan Context

Kenya’s fishing environments are diverse and demanding:

Freshwater lakes such as Lake Victoria, Naivasha, and Turkana
Rivers and dams with variable current and debris load
Marine waters along Mombasa, Kilifi, Malindi, Watamu, and Lamu
Aquaculture systems including ponds, cages, tanks, and hapas

Each environment places different stresses on netting, including UV radiation, abrasion, biofouling, salinity, and mechanical load. Effective netting selection must therefore balance material properties, construction method, and application-specific design.

Types of Fishing Netting Used in Kenya

Gill Nets

Gill nets catch fish by allowing them to partially pass through the mesh, where they are retained by the gills.

Common applications:

Lake Victoria commercial fishing
Coastal marine fisheries
Targeted size-selective fishing

Key characteristics:

Mesh size determines fish size caught
Requires regulatory compliance to avoid juvenile capture
Typically manufactured from PE or Nylon

Gill nets are efficient but require careful specification to balance productivity and sustainability.

Seine Nets

Seine nets are actively deployed and hauled to encircle fish.

Common applications:

Schooling fish near shorelines
Shallow lake and coastal waters
Cooperative and commercial operations

Key characteristics:

Large surface area coverage
Combination of floating and sinking sections
High tensile strength requirements

Seine nets demand robust twine diameter and reinforced edges due to high hauling loads.

Cast Nets

Cast nets are circular, hand-thrown nets used in shallow waters.

Common applications:

Small-scale fishing
Bait collection
Artisanal operations

Key characteristics:

Lightweight construction
Fine mesh options
Easy to repair and transport

They are popular for their simplicity and low operational cost.

Trawl or Drag Nets

Trawl nets are towed through water to capture fish along a defined path.

Common applications:

Marine fishing
Riverine environments
Specialized commercial use

Key characteristics:

High abrasion resistance required
Strong knot construction
Heavy-duty materials

Because of environmental impact concerns, trawl nets must be used responsibly and in compliance with regulations.

Happa Nets and Enclosure Nets

Happa nets are containment nets used in aquaculture.

Common applications:

Fry and fingerling rearing
Stock separation
Growth control

Key characteristics:

Fine mesh for containment
High water flow permeability
Easy installation and removal

They are critical for controlled aquaculture production.

PE and Knotless Netting

Knotless netting, often raschel-constructed PE, is widely used across aquaculture and marine sectors.

Advantages:

Reduced snagging
Uniform load distribution
Lower injury risk to fish

Knotless netting improves durability and handling efficiency, especially in cage systems.

Protective Netting (Bird and Predator Nets)

Protective netting prevents loss from birds, reptiles, and other predators.

Common applications:

Pond and cage protection
Hatcheries
Marine installations

These nets prioritize coverage and UV resistance over capture efficiency.

Cargo Elastic and Latex Netting

Elastic netting secures equipment and catch during transport.

Applications include:

Boat safety
Gear bundling
Marine logistics

Though auxiliary, these nets are part of complete marine netting systems.

Key Technical Specifications to Evaluate

Mesh Size and Shape

Mesh size controls fish size selection and must comply with Kenyan fisheries regulations. Incorrect mesh size increases bycatch and legal risk.

Twine Material and Diameter

Common materials include:

Polyethylene (PE): Lightweight, UV resistant
Nylon: High elasticity and strength
Polypropylene: Lightweight but lower abrasion resistance

Twine diameter directly affects strength, weight, and drag.

Knot vs Knotless Construction

Knotless netting:

Reduces debris accumulation
Improves water flow
Enhances durability

Knotted nets offer easier field repair in some cases.

UV and Chemical Resistance

UV-stabilized netting performs significantly better under Kenyan sunlight. Marine nets must also resist salt-induced abrasion and biofouling.

Buoyancy Characteristics

Floating nets for surface operations
Sinking nets for bottom deployment

Correct buoyancy improves operational control.

Durability and Maintenance

Availability of repair twine, needles, and accessories is essential for long-term cost control.

Applications of Fishing Netting in Kenya

Commercial Capture Fisheries

Require heavy-duty seine nets, trawl nets, and gill nets with reinforced construction.

Aquaculture and Cage Culture

Use happa nets, cage containment nets, and predator exclusion nets that balance strength with water flow.

Small-Scale and Artisanal Fishing

Prioritize affordability, repairability, and local availability.

Marine Infrastructure and Safety

Includes barrier nets, safety nets, and cargo netting for marine operations.
