How Probiotics Helps Shrimp Aquaculture in Bangladesh
Bangladesh is a densely populated country with extensive water bodies in the form of lakes, ponds, rivers and estuaries, covering millions of hectares. Aquaculture has been prevalent in Bangladesh for a long time and according to reports, the resultant 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 industrial development. In 2016-17, it was reported that over 40,000 tonnes of shrimp were exported to the international market and contributed to the economy of the country. However, it is essential to note that shrimp aquaculture productivity is very low compared to other countries in the world, and it is facing many challenges related to sustainable aquaculture.
Diseases and Use of Antibiotics
As shrimp production grows in Bangladesh, the perennial problem of diseases has affected aquaculture production. The shrimp health and quality is of paramount importance, and thus it impacts 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 harm the environment and can lead to health hazards. Moreover, it is expensive for the farming community involved in shrimp production. Thus, disease management has always been one of the primary concerns among shrimp farmers in Bangladesh.
Probiotics in recent times have emerged as a promising, eco-friendly alternative to antibiotics to manage 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, provides health benefits to the host. In aquaculture, probiotics are capable of modifying microbial community in the host, which leads to major benefits like better feed use, improved nutritional value and good immunity response. It is also well known for improving water quality. One of the major highlights of probiotics is that they are biological agents which 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 carried out to study the applications, effects and acceptability of probiotics for 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 like length and survival rate of Penaeus monodon was increased by supplying probiotics as a feed supplement. Another study reported better feed conversion ratio, nutrient utilization capacity, pathogenic resistance and boost in protein and phosphorus utilization rate of the tiger shrimp in Bangladesh. Thus, the use of eco-friendly probiotics in Bangladesh can help in the sustainable expansion of aquaculture.

Organic Probiotic Solutions For Aquaculture & Fish Farming
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 essentially helps in low or no water exchange, adds 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 boost the effectiveness of biofloc fish farming technology by helping factors like growth, digestion, metabolism, disease resistance and water quality in aquaculture.
