You're welcome Parnasri. Sure it is my pleasure to share knowledge and help others especially if they see the value of nature's gift which are just easily sourced in the surroundings. I will be glad to share it with you and women doing fish- drying business.
Great project for and with women community-fish drying business! I suggest you process turmeric roots into natural preservative-liquid that will be useful during drying-stage whether you use solar heating units or sun-dry process. This is what we do here locally. I understand India has abundant supply of this plant.
