NUWGP studies shrimp growth.
In the integrated multi-trophic aquaculture laboratory established at NULES with EU funding as part of the Erasmus+ AFISHE grant project, the growth rates of giant freshwater shrimp were studied.(Macrobrachium rosenbergii)Shrimp cultivation took place in a RAS laboratory setup with a recirculating water purification unit designed according to the integrated multi-trophic aquaculture concept.
Primarily, crustacean products in food establishments and markets are imported; however, Ukraine has the potential to cultivate its own aquaculture products. Currently, there is a high level of interest among many entrepreneurs in Ukraine in developing the technology for growing Macrobrachium shrimp in RAS conditions. Economic indicators are also important, as adequate temperature regimes must be maintained for fast growth rates and shrimp must be provided with complete feeds. Therefore, effective purification of polluted water in the RAS system will help minimize heat losses and reduce water consumption per unit of cultivated product.
The problem of providing shrimp with quality feeds is equally relevant, as the feed must contain all components necessary for growth, be balanced, and well absorbed. Despite numerous reports of excellent results from shrimp cultivation in domestic households in Ukraine using homemade mixtures (vegetables, greens, fish, grains, etc.), for cultivating Macrobrachium in full-fledged RAS, we believe that a more rational approach is to use specialized pelleted feeds. Thus, a compound feed from the domestic manufacturer of aquaculture feeds, 'Fishery.tech', was used for feeding. A memorandum of cooperation between this enterprise and NULES was signed (January 21, 2025). The research results confirmed the proper growth rates of shrimp when using such feeds and the high efficiency of pollution removal with the applied biological purification technology.
In the future, it is planned to expand cultivation volumes to study the main technological parameters of shrimp cultivation under semi-production conditions.
