Mobile Application



Rolled out



In Bangladesh, farmers have to combat various forms of crisis amidst volatile climate changes. Lack of information and suppliers for feed related problems are common amongst fish farmers in the country. Our revolutionary application was designed to bring a complete solution to all of these issues and make the lives of farmers easier.

OneFish is a Business-To-Business(B2B) mobile application, connecting fish farmers and traders in Bangladesh and making lives easier by reshaping modern aquaculture. 
ARITS developed OneFish for WorldFish’s Bangladesh Aquaculture Activity project, funded by USAID. OneFish has emerged as a comprehensive, digital, one-stop solution specifically designed for fish farmers, while addressing a myriad of challenges, creating a meaningful impact on their lives.


Since its inception, ARITS in collaboration with WorldFish, successfully trained and onboarded over 26,000 fish farmers onto the OneFish platform, showcasing its effectiveness within the aquaculture community. The platform’s impact extends beyond individual farmers, contributing to WorldFIsh’s goal of overall growth and sustainability of the fish farming industry.

OneFish’s information services can equip farmers with real time weather updates available for their area which make it perfect for farmers to have the necessary information they need for their aquatic stock.

The feed related section boasts some of the best tools on the application as it allows Farmers to calculate feed, conversion rate for feed for proper utilization and to have access to different kinds of recipes for fish farming. Using the Feed Conversion Rate (FCR) tool, farmers can better understand, analyze and manage feed optimization. Normally, this would have to be done manually by trial and error to understand how much feed is required.

The FCR tool shows farmers the total amount of feed required to produce a certain unit of fish. By inputting accurate information such as the starting weight of the fish stocked, total weight of the fish in the pond and the amount of feed used, the FCR tool will generate an accurate conversion rate which farmers can use to maintain their aquaculture. 

The Knowledge Bank features several useful articles which can also be bookmarked. From costs associated with fish farming to setting up your first pond with the latest technologies, the Knowledge Bank is a wealth of information.
