• Portability: Lightweight and ergonomic designs facilitate quick movement between boats and storage facilities.
• Capacity: Equipment must match the typical catch size to avoid overloading or repeated trips that delay processing.
• Safety Features: Hand grips, anti-slip surfaces, and stable bases reduce the risk of accidents during offloading.

In a busy fish market such as the one at Malindi, the use of standardized, stackable fish crates allows for rapid unloading and sorting, minimizing handling time and exposure to heat.

4.1.2 Facilities at the Landing Site

Landing sites require appropriate infrastructure to support efficient and sanitary offloading operations. The quality of these facilities often determines the market value of fish and compliance with public health regulations.

Essential Facilities for Offloading Operations

• Landing Platforms: Constructed from concrete or treated timber, these provide stable footing for workers and equipment during unloading.
• Cold Rooms and Ice Plants: On-site refrigeration or ice production facilities help maintain the cold chain immediately after offloading.
• Weighing and Sorting Sheds: Covered areas where fish are weighed, graded, and packed, protecting both product and workers from harsh weather.
• Sanitation Stations: Facilities equipped with running water, soap, and disinfectant for cleaning hands, tools, and surfaces.
• Access Roads and Paths: Well-maintained routes enable vehicles and hand trolleys to move fish quickly from boats to storage or transport trucks.

Characteristics of Well-Designed Landing Facilities

• Proximity to Water: Facilities should be close to the docking area to reduce manual handling and time out of water.
• Drainage Systems: Proper drainage prevents standing water, which can harbor bacteria and create safety hazards.
• Lighting and Security: Adequate lighting supports early morning or late-night offloading, while security deters theft and vandalism.
• Waste Disposal Points: Clearly marked bins and composting areas facilitate the safe removal of fish offal and used packaging.
• Accessibility for All Users: Design should consider the needs of women, youth, and people with disabilities who participate in fisheries.

At the Mfangano Island landing site, the construction of a new ice plant has significantly reduced post-harvest losses by ensuring that fish are immediately chilled after offloading.

4.1.3 Procedures for Safe and Efficient Offloading

Adhering to standardized procedures during offloading is crucial for product quality, worker safety, and regulatory compliance. Each step must be performed with attention to detail and hygiene.

Steps for Offloading Fish at a Landing Site

1. Prepare Offloading Area: Clean all surfaces, assemble necessary equipment, and ensure sanitation stations are stocked with soap and disinfectant.
2. Position Boat Securely: Moor the boat firmly to the landing platform to prevent movement during unloading.
3. Inspect Equipment: Check that crates, nets, and trolleys are clean and in good working order.
4. Transfer Fish Using Proper Tools: Use lifting nets or crates to move fish from the boat to the landing platform, minimizing direct contact.
5. Sort and Weigh Fish: Place fish in the weighing area, separate by species or size as required, and record weights accurately.
6. Move Fish to Cold Storage or Transport: Use hand trolleys or carts to transfer fish to ice boxes, cold rooms, or awaiting vehicles.
7. Clean and Disinfect Equipment: Immediately after use, wash all equipment and sanitize surfaces to prevent contamination.
8. Dispose of Waste Properly: Collect fish offal and spoiled products for composting or safe disposal according to local regulations.

These procedures are commonly observed at county-operated landing sites along Lake Naivasha, where local fisheries officers supervise each step to ensure adherence to public health standards.
