Indigenous knowledge: Use of green mint and basil for keeping fish freshness in open markets

Review: Abdel Rahman El Gamal (Founder of the website)

Like many people I used to see green plants below fish displays. Frankly speaking, I never paid attention to the type of such plants thinking that it serves as a cushion preventing displayed fish from possible skin abrasion. Only last month (April 2019), I asked several fish displayers and got to know that the green plants are either mint or basil and the main purpose is to keep the flying insects out of the display. This practice has been transferred over generations. In order to investigate this matter and try to find the scientific base for such practice, it becomes obvious that such plants are natural insect repellent and are found effective and economical in keeping mosquitoes, ants, and flies out. Afterwards, I went to my photo collections and discovered that using green mint or basil is a common practice whenever fish was transferred or displayed in open systems.
