Abstract:

Trace elements are important for improving the productivity and health of aquatic animals. Manganese (Mn) is a micronutrient that supports various physiological functions. It plays a key role in enzyme production, hormone formation, the immune response, reproductive processes, metabolic activity and antioxidant functions. Some aquafeed ingredients naturally provide Mn to meet the requirements of aquatic animals, but supplementation may be necessary for optimal growth. However, both excess and deficiency of Mn can disrupt metabolic functions and overall health. This review evaluates the role of Mn supplementation in the feed of fishes and crustaceans in improving growth performance, feed utilization, antioxidant defense, tissue accumulation, proximate composition and enzyme activity.

Essential Minerals for Bone Health

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Minerals

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
