What are rats used for on a ship? - briefly
«Rats» served as a readily available source of protein for crew members during long voyages and were occasionally used as live bait to attract larger pests. Their presence signaled inadequate sanitation, prompting corrective measures.
What are rats used for on a ship? - in detail
Rats aboard vessels have served several practical functions.
- They consume spilled grain, dried meat, and other organic debris, reducing the amount of waste that could attract larger predators or accelerate rot.
- Their presence signals deterioration of stored provisions; a sudden increase in activity often precedes spoilage, prompting crews to inspect and rotate supplies.
- In emergency situations, rats provide a supplementary source of protein; sailors have roasted or boiled captured individuals when fresh food is scarce.
- They act as natural training targets for ship cats, helping maintain the felines’ hunting instincts and ensuring a continuous line of pest control.
- Historically, naval authorities have collected shipboard rats for scientific study, using them as specimens in early veterinary and epidemiological research.
The benefits are offset by significant drawbacks. Rodents gnaw on ropes, wooden fittings, and canvas, compromising structural integrity and sail performance. Their urine and droppings contaminate food stores, water barrels, and living quarters, fostering the spread of pathogens such as plague‑bearing fleas and leptospira bacteria. Consequently, effective rodent management—through traps, cat deployment, and regular sanitation—remains a critical aspect of maritime operations.
