How Probiotics Helps Shrimp Aquaculture in Bangladesh
Bangladesh is a densely populated country with extensive water bodies, including lakes, ponds, rivers, and estuaries, covering millions of hectares.
Aquaculture has been prevalent in Bangladesh for a long time, and according to reports, the production has increased from 7,12,640 metric tons in 2000 to 2,060,408 metric tons in 2016.
The shrimp aquaculture in Bangladesh supports coastal fishing and industrial development.
In 2016-17, it was reported that over 40,000 tonnes of shrimp were exported to the international market, contributing significantly to the country’s economy.
However, it is essential to note that shrimp aquaculture productivity is relatively low compared to other countries worldwide, and it faces numerous challenges related to sustainable aquaculture.
Diseases and Use of Antibiotics
As shrimp production in Bangladesh grows, the perennial problem of diseases continues to affect aquaculture production.
The shrimp’s health and quality are of paramount importance, and thus, they impact the whole production cycle.
Additionally, the aquatic ecosystem containing water influences the health of shrimps in aquaculture.
A large quantity of pathogens living in culture water can deteriorate water quality and cause different diseases.
The traditional method of using antibiotics against diseases harms the environment and can lead to health hazards.
Moreover, it is expensive for the farming community involved in shrimp production.
Thus, disease management has long been a primary concern among shrimp farmers in Bangladesh.
In recent times, probiotics have emerged as a promising, eco-friendly alternative to antibiotics for managing shrimp diseases in aquaculture.
It has captured the attention of the scientific community, and the positive results are very encouraging.
What are Probiotics?
Probiotics, in general terms, can be defined as living beneficial microorganisms, which, when supplied in sufficient quantity, provide health benefits to the host.
In aquaculture, probiotics are capable of modifying the microbial community within the host, leading to significant benefits such as improved feed utilization, enhanced nutritional value, and a robust immune response.
It is also well known for its ability to improve water quality.
One of the major highlights of probiotics is that they are biological agents that are non-toxic and cause no adverse side effects to other aquatic beings.
Effects and Benefits
Multiple studies and research have shown many effects and benefits of probiotics for shrimps, which are listed below.
- Increased survival rate
- Improved population of beneficial microorganisms
- Nitrogen & Phosphorus reduction
- Increased DO
- Wet weight gain
- Better feed conversion ratio
- Enhanced water quality
- Specific growth rate
- Increased yield
- Reduced average mortality rate
Probiotics for Shrimp Aquaculture in Bangladesh
In Bangladesh, various studies have been conducted to investigate the applications, effects, and acceptability of probiotics in shrimp farming.
The results have shown that it is efficient in improving water quality, growth performance, and disease management.
Bacterial infections like Vibriosis have affected Penaeids shrimp, and the majority of probiotics used are found to be effective against it.
The body characteristics, such as the length and survival rate of Penaeus monodon, were increased by supplying probiotics as a feed supplement.
Another study reported a better feed conversion ratio, increased nutrient utilization capacity, enhanced pathogenic resistance, and a higher protein and phosphorus utilization rate in tiger shrimp in Bangladesh.
Thus, the use of eco-friendly probiotics for shrimp farming in Bangladesh can help in the sustainable expansion of aquaculture.
Biofloc Fish Farming
Biofloc fish farming in India has been helping farmers, and it can assist Bangladesh to boost aquaculture output without affecting the environment.
It utilizes beneficial bacteria to convert organic waste matter into feed for the fish.
Thus, biofloc technology helps achieve low or no water exchange, provides an external carbon source, and offers high oxygenation by recycling waste.
It is a robust technology for disease management and lessens environmental impact. Biofloc fish farming in India is slowly reaping positive results, and so can Bangladesh.
Probiotics can be used to enhance the effectiveness of biofloc fish farming technology by improving factors such as growth, digestion, metabolism, disease resistance, and water quality in aquaculture.
Organica Biotech is one of the leading companies with a wide range of advanced products for sustainable aquaculture.
Probiotic products, such as Bioclean Aqua and Bioclean Aqua Plus, can help boost growth, improve survival rates, reduce pathogen levels, and maintain an environmentally friendly culture system for shrimp in Bangladesh.
It can also support biofloc fish farming. Affordable and cost-effective products can help farmers in Bangladesh increase their aquaculture output.
