Higher levels of iron in fish and aquatic plants also has negative effects on the people or creatures consuming them. Repercussions Large amounts of iron promote growth of algae, which can block sunlight from other plants and can disrupt habitats and feeding practices. Extensive algae presence lowers water freshness and promotes stagnation.
