Aquaculture is an essential and emerging food-producing sector in the world. The fishery yearbook 2017 states that 153 million tons of total fish production used for human consumption. But the production is always hindered by disease and environmental situations.
These conditions result in severe financial losses for the companies. However, the use of antibiotics in aquaculture causes the resistance of pathogens. Therefore, it is a significant risk that resistant bacteria can transfer from aquatic species to humans.
Probiotics provide a promising solution to this problem. Moreover, eco-friendly treatments like probiotics play an influential role in aquaculture. Are you looking for the application of probiotics in aquaculture? What are the safety considerations? Don’t worry. We will provide precise answers to your questions. Let’s begin.
What are Probiotics?
Probiotics are organisms that help balance gut microbiota. Probiotics are a nutritious food source and act as eco-friendly biological control mediator. Probiotics are ‘water additives’ in aquaculture.
Different terms generally describe probiotics as beneficial, healthy, and eco-friendly bacteria. The primary function of healthy bacteria is to detoxify the gut of the host. Different types of probiotics help to maintain the health and growth of aquaculture.
What Are the Applications of Probiotics in Aquaculture?
Probiotics have several practical applications in the field of aquaculture. The global demand for seafood is increasing daily. Probiotics have helped meet the rising requirement of sea organisms. The advantages of probiotics are significant in aquaculture.
Probiotics have been used as a part of aquaculture to improve the growth of farming fish. Furthermore, Bacillus sp. probiotics have shown a positive approach in increasing the weight and size of fishes. Hence, the use of probiotics acts as a growth promoter for edible fish.
Inhibition of Harmful Bacteria
Today consumers demand natural and additive-free products. Further, the use of antibiotics imparts harmful effects on the health of consumers. Thus, the use of probiotics is a vital alternative for the inhibition of harmful bacteria. Probiotics also control disease and infections in aquaculture species.
Improvement in Nutrient Digestion
Probiotics have beneficial effects on the digestive system of aquatic organisms. Because probiotics produce extracellular enzymes and growth factors, these extracellular enzymes are proteases, lipases, and amylases.
With the help of these enzymes, nutrients efficiently absorb in an organism’s gut. Therefore, probiotics also help to enhance the nutrient absorption in fish and shrimps.
Stress in fish’s life reduces the total production. The fish becomes weak and dislikes to take food; this is called ‘food phobia.’ Probiotics can relieve this type of stress. The probiotic outcomes provide a high possibility of stress prevention in other aquatic organisms.
Improving the Quality of Water
Probiotics may be an eco-friendly option to improve culture’s water quality. The quality of water is reduced due to the high concentration of nitrogen and bad-smelling salts. Therefore, the utilization of probiotics suggests enhancing water quality. Probiotics used in farms can improve water quality by balancing the pH and nitrogen levels.
In several studies, researchers recorded water quality during the addition of probiotic strains. Gram-positive Bacteria have more positive effects than Gram-Negative bacteria. Gram-Positive Bacteria are more efficient in transforming organic matter into carbon dioxide.
Maintaining a high level of probiotics in culture farms can reduce the organic debris. Probiotics help to support the production of phytoplankton.
What are The Advantages of Probiotics in Aquaculture?
- Reduction of harmful bacteria in the gut or elsewhere
- Provide nutrition to aquatic animals
- Improved digestibility and microbial adjustment
- Host immune response stimulation
- Improve water quality and an eco-friendly treatment
- Reduction of blue-green algae
- Cleanliness of pond’s soil
- Reduction of ammonia level in water ensuring the healthy production of aquatic animals
- A decline in green vibrio counts
- Water exchange which declines water pumping costs
What Should Be the Safety Considerations for Probiotics?
It is crucial to apply the exact quantity of probiotics to the culture farm. Quality probiotics ensure proper growth and give bio-security in farming. Generally, probiotics used in the food industry have been considered safe. Probiotics have no adverse effects.
What Is the Bottom line Here?
The current global crisis and increasing production cost have put the pressure on the food production community to ensure sufficient food for the growing population. Thus, aquaculture is a promising way to meet the ever-increasing demand for fresh seafood. Probiotics are playing a significant role in maintaining the quality of aquatic organisms.
The development of aquaculture as an industry has increased over the past decade. Therefore, the need for increased disease resistance, development of aquatic organisms, and feed efficiency has induced probiotics. probiotics improve the water quality and control of bacterial infections. probiotics are safe to use.
