Iodine and salt can be harmful to freshwater fish in aquaculture because they can disrupt the osmoregulation process. Freshwater fish have a lower salt concentration inside their bodies compared to the surrounding water. Adding iodine or excess salt can interfere with the fish's ability to regulate the balance of water and salts, leading to stress, dehydration, and ultimately harming their health.

Mr. Adhan, Iodine mixed with salt can be harmful to freshwater fish fingerlings in aquaculture due to its potential toxicity. Elevated iodine levels can disrupt fish osmoregulation, causing stress and negatively impacting their growth and survival. Maintaining proper water quality and avoiding excessive iodine concentrations is crucial for the well-being your fish. so be cautious while handling fingerlings.

Because it can interfere with the osmoregulation of freshwater fish in aquaculture, iodine and salt can be mixed to create a solution that is toxic to the fish. The precise balance of salts and minerals that freshwater fish maintain in their bodies can be upset by exposure to too much iodine and salt, which can result in stress, disease, or even death.

Iodine for freshwater aquarium will cause stress, disturbing osmoregulation and consider toxic to fish which has been effect on growth of fish.
