Some experiments were completed last yaer, 2021 and other started which are still succesfully continuing. KU implements experiments in their experimental RAS facilities for fish and for shrimps. Experiments are directly run by bachelor and master students of Klaipeda University what is a part of their practical skills training and data collection for their course works or bachelor and master thesis, supervised by AquaVIP project partners Nerijus Nika and Gintautas Narvilas. These experiments have high applied significance and knowledge gained are important for technology developement and succesful commercialization of results.
In 2021 two experiments were completed. Master student Gerda Petreikytė was performing experiment on Nile tilapia growth efficiency in brackish water and succesfully defended her master thesis on the same topic. Second year bachelor student Jonas Lelys ran an experiemnt on shrimp cultivation process optimisation assessing possibility to sort shrimp by size and improve growth and survival. Course work was defended on the basis of results of experiemnt.
Last year, two other experiemnts with new batch of shrimps started, also under care of Jonas Lelys and supervised by Nerijus Nika and Gintautas Narvilas. One part of experiment is testing the new shrimp tower technology prototype, evaluating work of the the system, handling procedures and status of animals in the tower. The other part of experiment is to test handling stress induced mortality of shrimps in standard RAS tanks and new tower tank. Results will be used for preparation of bachelor thesis of Jonas and also for further develpement and transfer of technology to businness partners.
In the Fisheries and Aquaculture Laboratory of MRI we started experiment on rainbow trout grow-out and RAS technology performance in brackish water artfically prepared using geothermal brine from 1300 m deep Cambrian aquifer, which is highly rich in sodium, calcium, magnesium and other, including trace, elements, and could be promissing source of artificial marine water, to develop marine RAS in wester Lithuania. Experiment is run by second year master sudent Marius Diadyk and results of the experiment (system performance, water quality dynamics, fish growth and stress, meat quality and element bioaccumalation) will be used to prepare his master thesis.
