Maintaining Your Fishing Nets: 5 Essential Tips to Prevent UV Damage and Saltwater Corrosion in Kenya

Fishing nets are not consumables. They are capital assets.

For commercial fishing fleets, aquaculture operators, and cooperative societies across Kenya, nets represent one of the largest recurring investments in fishing operations. Whether deployed in the Indian Ocean along Mombasa and Malindi, in Lake Victoria’s high-pressure inland fisheries, or within inland cage and pond systems, fishing nets are subjected daily to forces that silently degrade their performance long before visible failure occurs.

Ultraviolet (UV) radiation and saltwater exposure are the two most destructive environmental factors affecting net longevity in Kenya. Their impact is cumulative, irreversible, and often underestimated. Poor maintenance shortens usable net life, increases replacement frequency, reduces catch efficiency, and introduces operational risk through unexpected failures.

This professional maintenance guide is written specifically for fleet owners, aquaculture managers, and commercial operators managing multiple nets across vessels or production systems. It delivers practical, technical guidance grounded in Kenyan fishing conditions, aligned with Maimun Fishing & Tackles Ltd (MFT) professional-grade netting standards.

Why Fishing Net Maintenance Is a Business-Critical Function

In commercial fishing, net failure is not a random event. It is the predictable outcome of unmanaged degradation.

Hidden Strength Loss Before Failure

Fishing net fibers degrade at a molecular level long before they break. UV radiation weakens polymer chains, while saltwater accelerates mechanical abrasion at knots and mesh intersections. By the time holes or tears appear, tensile strength may already be reduced by 30–50 percent.

This loss directly affects:

Catch retention efficiency
Ability to withstand load during hauling
Resistance to tearing under wave or current pressure

In Kenya, many fleets replace nets 30–50 percent earlier than necessary due to avoidable UV and salt-related damage. Structured maintenance protocols can extend usable net life by up to 40 percent, reducing cost per kilogram landed and stabilizing operating budgets.

extract maximum value only when maintenance is enforced from first deployment.

Understanding the Two Primary Net Killers in Kenya

1. Ultraviolet (UV) Radiation

Kenya’s equatorial position exposes fishing gear to intense UV radiation year-round. UV breaks down polymer chains in synthetic fibers, causing:

Loss of elasticity in Nylon
Brittleness in HDPE
Progressive knot failure

High-altitude inland lakes and reservoirs experience higher UV intensity than many coastal areas, making UV protection equally critical for inland fleets.

2. Saltwater Exposure

Saltwater damage is primarily mechanical, not chemical.

When seawater dries on nets:

Salt crystals form abrasive surfaces
Knots stiffen and lose flexibility
Micro-friction increases during hauling

Without rinsing, salt deposits continue damaging fibers even when nets are not in use.

Tip 1: Control UV Exposure During Drying and Storage

Quick Advisory:
UV radiation is the leading cause of premature net failure in Kenya. Shade drying is not optional for professional fleets.

Technical Breakdown

Nylon and HDPE nets degrade differently under UV exposure:

Nylon: Loses elasticity, increasing tearing risk under load
HDPE: Becomes brittle, leading to sudden breakage

Common damaging practices include:

Drying nets on open beaches
Leaving nets spread on rooftops
Prolonged sun exposure after rinsing

Best Practice for Kenyan Fleets

Dry nets under shade or UV-filtered roofing
Minimize direct sunlight exposure to the shortest possible time
Rotate drying orientation to prevent localized degradation
Prioritize airflow over heat

Well-ventilated shade drying preserves fiber integrity far longer than sun baking. Nets maintained this way retain uniform tensile strength across mesh and knots.

Tip 2: Rinse Saltwater Nets Immediately After Retrieval

Quick Advisory:
Saltwater damage continues after fishing stops. Freshwater rinsing halts degradation.

Technical Breakdown

Salt crystals form sharp, abrasive surfaces as seawater evaporates. These crystals:

Cut into fibers during hauling
Trap moisture, increasing wear
Reduce knot flexibility and load tolerance

Correct Marine Protocol

Immediately after retrieval:

Rinse nets thoroughly with freshwater
Focus on knot intersections, lead lines, and reinforced edges
Allow controlled drainage before drying

Even minimal freshwater rinsing dramatically reduces long-term damage.

Marine fleets using professional systems from:
https://shop.mft.co.ke/marine/boat-equipment
and
https://shop.mft.co.ke/marine/ropes
experience reduced wear across entire gear assemblies when nets are properly rinsed.

Tip 3: Inspect and Repair Small Damage Before Redeployment

Quick Advisory:
Small damage spreads exponentially. Early repair prevents catastrophic failure.

How Net Failure Progresses

Fishing nets fail progressively:

Fraying begins at knot points
Mesh deformation spreads under load
Tears propagate along stressed lines

Ignoring a single damaged section can result in complete net loss during hauling.

Fleet-Level Inspection Protocol

Professional fleets should enforce:

Visual inspection after every retrieval
Immediate repair of damaged mesh
Reinforcement of high-stress zones

Repair tools and accessories sourced from
https://shop.mft.co.ke/fishing/fishing-accessories
reduce downtime and extend deployment cycles.

Tip 4: Store Nets Dry, Elevated, and Properly Coiled

Quick Advisory:
Improper storage degrades nets even when unused.

Common Kenyan Storage Mistakes

Leaving nets on damp ground
Storing while partially wet
Over-compressing coils

These practices cause:

Mildew growth
Fiber fatigue
Permanent mesh deformation

Correct Storage Standards

Ensure nets are fully dry before storage
Elevate nets off floors using racks or pallets
Coil loosely to preserve mesh geometry

Aquaculture operators using cage materials such as
https://shop.mft.co.ke/fish-cage-net-material-x-1-bundle-x-50m-x-7m
should apply identical standards during harvest and maintenance cycles.

Tip 5: Match Maintenance Intensity to Net Material

Quick Advisory:
Nylon and HDPE require different care. Uniform protocols shorten lifespan.

Nylon Nets

Inspect frequently for abrasion
Preserve elasticity through controlled drying
Ideal for high-frequency deployment

HDPE Nets

Monitor for brittleness
Limit prolonged UV exposure
Replace earlier when knot rigidity increases

Fleet owners managing mixed inventories must label nets clearly and train crews accordingly. Selecting material-appropriate nets from:

and

simplifies long-term planning.

Saltwater vs Freshwater Maintenance Requirements

Quick Advisory:
Marine environments accelerate degradation. Freshwater reduces salt abrasion but not UV damage.

Marine fleets: Emphasize rinsing, drying, knot inspection
Lake Victoria fleets: Focus on UV protection and abrasion control
Inland aquaculture: Prioritize biofouling removal and structural integrity

Neglect produces predictable failure regardless of environment.

Maintenance as a Fleet-Level ROI Strategy

Professional fleets treat nets as depreciating assets with scheduled maintenance.

This approach:

Reduces emergency purchases
Improves catch consistency
Lowers cost per deployment

Operators sourcing complete systems through

achieve full value only when maintenance discipline is enforced.

Common Net Maintenance Mistakes in Kenya

Avoid:

Drying nets on hot sand or concrete
Storing nets wet overnight
Ignoring small tears
Mixing Nylon and HDPE without labeling

Correcting these errors yields immediate durability gains.
