Transporting harvested fish to landing beaches is a critical phase in the fisheries value chain that directly affects fish quality, market value, and sustainability of fishing operations. In Kenya, many fishermen operate from remote coastal areas and inland water bodies, where the distance and conditions between the catch site and landing beaches vary significantly. Proper handling during transport ensures the fish remain fresh and safe for consumption, reduces post-harvest losses, and complies with food safety regulations. This chapter focuses on best practices in stowage for harvested fish, emphasizing proper arrangement, layering with ice, and avoiding damage during transport.

3.1 Stowage for Harvested Fish Reports

Stowage refers to the systematic placement and securing of harvested fish during transport to prevent spoilage, physical damage, and contamination. In the Kenyan fisheries sector, from artisanal fishermen landing at small beaches to commercial fishers using larger vessels, effective stowage practices are essential to maintain fish quality. The cold chain often begins right at the boat or fishing site, extending to the landing beach storage facilities. Understanding how to arrange fish in containers or cold storage, apply ice correctly, and avoid overloading is fundamental for fisheries professionals.

3.1.1 Proper Arrangement of Fish in Containers or Cold Beach Storage

Proper arrangement of fish during transport and storage is vital to maintain quality by ensuring adequate airflow, preventing crushing, and facilitating effective cooling. In Kenya’s coastal fishing communities such as Kilifi and Lamu, fishermen use insulated containers or cold rooms at landing beaches to store fish before market distribution. Arranging fish correctly optimizes space while preserving freshness and appearance.

Key Practices for Proper Arrangement

• Uniform Size Grouping: Sorting fish by size before stowage prevents smaller fish from being crushed under heavier ones, reducing physical damage and bruising.
• Orientation of Fish: Placing fish with heads and tails aligned minimizes space wastage and allows air and cooling agents to circulate evenly around each fish.
• Use of Containers with Drainage: Containers designed with drainage holes prevent accumulation of melted ice water, which can accelerate spoilage if fish remain submerged.
• Layer Separation: In cold beach storage, placing fish in shallow layers rather than deep piles ensures better temperature control and easier inspection.
• Avoiding Direct Contact with Floor or Walls: Elevating containers or using pallets prevents contamination from dust, dirt, or moisture on surfaces, a practice followed by fishmongers at Mombasa’s Tudor fish market.

3.1.2 Layering Fish with Ice for Optimal Cooling

Ice is the most common and effective cooling medium used by Kenyan fishermen to preserve fish freshness during transport and storage. Proper layering of fish with ice ensures rapid cooling and maintains low temperatures throughout the stowage volume. This practice is especially important in hot climates where ambient temperatures can quickly degrade fish quality.

Principles of Effective Ice Layering

• Alternating Layers of Fish and Ice: Fish should be placed in layers separated by a generous layer of crushed ice, typically 2 to 5 cm thick, to ensure uniform cooling.
• Sufficient Ice Quantity: The volume of ice should be at least equal to the volume of fish; under-icing leads to temperature rise and bacterial growth.
• Use of Crushed Ice: Crushed ice has a larger surface area than block ice, providing faster cooling and better coverage around irregularly shaped fish.
• Top Layer of Ice: A final thick layer of ice on top of the stowage acts as insulation against external heat and prolongs freshness during transport.
• Regular Ice Replenishment: For longer journeys, ice must be replenished periodically, as practiced by commercial fish transporters supplying Nairobi markets from Lake Victoria.

3.1.3 Avoiding Overloading and Compression Damage

Overloading containers or cold storage units with fish can cause compression damage, where the weight of upper layers crushes fish below, leading to bruising, broken scales, and rapid spoilage. Kenyan fisheries professionals must balance maximizing load capacity with preserving fish integrity.

Risks and Prevention of Overloading

• Weight Limits per Container: Each container or cold storage unit has a recommended maximum load weight, which should not be exceeded to prevent structural failure and damage to fish.
• Even Distribution of Weight: Fish and ice should be evenly distributed to avoid pressure points that cause localized damage.
• Use of Appropriate Container Sizes: Selecting containers sized to the catch volume helps avoid forced overpacking or multiple handling stages.
• Monitoring Load During Transport: Transporters should check load stability regularly to prevent shifting that can crush fish or damage containers.
• Training of Handlers: Educating fishermen and fish transporters on the consequences of overloading encourages adherence to best practices, as demonstrated during training workshops by the Kenya Marine and Fisheries Research Institute (KMFRI).

Chapter Summary

Transporting fish to landing beaches requires careful attention to stowage to maintain quality and prevent damage. Proper arrangement of fish in containers or cold storage areas ensures even cooling and reduces spoilage risks. Layering the fish with ice is essential to keep the catch fresh while avoiding overloading and compression that could bruise or crush the fish. Preservation techniques on board include various methods such as cooling, icing, freezing, refrigeration, and the use of refrigerated or chilled seawater, all aimed at slowing down spoilage and extending shelf life. Maintaining cleanliness through thorough cleaning and treatment of fish before storage is crucial to prevent contamination and preserve the fish’s market value. These combined practices ensure that fish arrive at the landing beaches in optimal condition for further processing or sale.
