Abstract/ Executive Summary:

The present study was carried out to evaluate the effects of commercial probiotics on the production of fresh and brackish water fishes and shrimps in commercial culture systems in Satkhira district of Bangladesh. With considering the principles of probiotics application in aquaculture, the study was designed to primarily compare the growth, water quality, disease and survivability of freshwater fishes and shrimps between probiotic and without probiotic culture systems. A total of 28, 60 and 12% of farms applied five types of feed probiotics, seven types of water probiotics and three types of soil probiotics supplied by the different animal health companies of Bangladesh. Using these probiotics there were significant differences found in the case of water quality parameters, growth and survival rate between treated and non-treated ponds. The average body weight and total production were observed to be higher in probiotic treated pond6. 68% fish farmer achieves the productions rate 01-50mon whereas it was 57% only and 250 Mon of 1% farmer. The frequency of occurring several diseases like epizootic ulcerative syndrome, gill and fin rot disease, EMS etc. was significantly lower after application of probiotics in the culture system.

Keywords: Probiotics, Disease, Shrimp, Finfish, Production

Location: Satkhira district of Bangladesh.

Start Date: 00-05-2016

End Date: 00-11-2016

Program Area: Resource Development and Management

Commodity: Aquatic animal

Objectives:

To be a very promising research area for nutrition, biological control, and disease prevention in aquaculture.

Methodology:

Study area and period- Data were collected from different farms of seven upazillas namely Assasuni, Debhata, Symnagar, Kolaroa, Kaligong, Tala, Patkelgata, Satkhira Sadar where aquaculture clusters were located of Satkhira district during May to November 2016. Questionnaire preparation and interviews- A total of 100 fish farms were visited for data collection. The questionnaire covered mainly farmer’s profiles, culture details, type of chemicals used with dose and price, the growth rate of the fishes, water quality parameters of the pond before probiotic use and after probiotic uses. Besides that, other primary data were collected through questionnaire interviews of retailers of animal medicine and representatives of pharmaceutical companies. Furthermore, secondary data were collected from different books, thesis papers, and published research papers, and so on from different sources like journals, textbooks, seminar library of FMRT Discipline, and the central library of Khulna University. Data Analysis- The collected data were scrutinized and summarized carefully and then they were tabulated. Some of the data were presented into local units, so those data were converted into international units. Data analysis was done by using Microsoft Excel 2010 and SPSS 16.0. One-way ANOVA was performed for comparison.

Achievement/Findings:

Many private industries have promoted their probiotic product without understanding the environmental impacts. Before using any type of drugs we should know about that drugs properly but most of the farmers use aquatic drugs unwisely which cause harmful effects on the cultural system. Probiotics can play a vital role in increasing survival rate, enhance growth, reduce pathogens, keep a friendly culture environment, and thus farmers ultimately would get higher production with a satisfactory economic return. In aquaculture systems, probiotic treatment offers a promising alternative to antibiotics. Improved Traditional aquaculture could enhance fish production and produce quality fish through using probiotics, as a developing country this could be a great opportunity for us to expand our export market. It’s a new invention in the aquaculture system that’s why it’s not widely spread to all farmers’ levels yet. These eco-friendly probiotics-based fish cultures should be practice more to know the better way of the culture system. However, the findings of this study should be applied extensively to the farmers’ level to increase more fish production. We never can ignore the role of fish culture as fish is our main source of protein, source of millions of people’s livelihood and one of the important earning sources of foreign currency.
