Today we want to tell you about the progress of the experiment on silver carp farming.    The main purpose of the experiment is to test how efficiently the fish can gain mass if fed exclusively with chlorella biomass. This is important because in the scientific literature the conversion rates of microalgae to silver carp biomass vary from 10 to 90 kg per 1 kg gain. This huge difference makes economic calculations difficult.   We created almost sterile conditions for the experiment: a 10-cubic meter pool with biofiltration and exclusion of external factors to get accurate data. Yearling silver carp were planted in the pool, and now, two weeks later, they are actively feeding on the chlorella biomass.   We carefully monitor the process: we separate, weigh and dose the biomass to the nearest tenth of a gram. At the moment the consumption of chlorella is about 140-150 grams per day, and we have already made 6 portions. It is very important that at the output we will be able to determine the conversion rate as accurately as possible - such data has not been published anywhere before.   The experiment will run until mid-September, as long as weather conditions allow. Once completed, we will conduct a fishery and count the conversions, which will allow us to derive the feeding rate of fathead trout on chlorella.   We are exploring ways to intensify rearing conditions for better results. The results of the experiment will be useful not only for silver carp, but also for other valuable fish species such as sturgeon and trout.    #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen

Study, that evaluate the in vitro protein hydrolysis of five algae (Arthrospira sp., Chlorella sp., Tisochrysis sp., Microchloropsis sp. and Ulva rigida) by the digestive proteases of Scophthalmus maximus, and to assess the effect of feeding turbot juveniles on diets supplemented with these algae in a 60-day feeding trial. As results, the ultrastructural study of the intestinal mucosarevealed an increase in the length of the microvilli and the absorptive surface in fish fed with the algae-supplemented diets, as well as decreased thickness of the lamina propria and the number of goblet cells. These results confirmed that the supplementation of turbot juvenile diets with low percentage of microalgae or U. rigida is appropriate for improving digestive functionality, as well as reducing the oxidation of lipids in the muscle. #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen https://lnkd.in/ejcpSGg6

Dear friends!!! Today we would like to share the results of our new project. -      Location: Novgorod region -      Customer: Yazhelbitsky fish farm -      Fish: trout In this project we helped to transplant fish for rearing from an RAS to a water body. This approach helps the fish to adapt to natural conditions and significantly reduce losses. The reservoir is small - only one hectare in area and up to three meters deep. This year we transplanted about 750 thousand twenty-gram fish, which was a total biomass of 15 tons of trout - a very large load for such a small reservoir. The request from the client was to maintain oxygen levels in the water and improve the immune system of the fish. We started applying chlorella from mid-May. The client was skeptical about the ability of chlorella to cope with such a difficult task. However, the results exceeded expectations - the oxygen level in the water reached 9-10 mg per liter. Every two days, we applied fertilizer for Chlorella development, which helped maintain optimal conditions. For every 100 kg of fish food is about 100 liters of oxygen are consumed for respiration and oxidation, which leads to the release of 130 kg of carbon dioxide. Chlorella, through photosynthesis, absorbs carbon and releases oxygen, but we needed to make up for the lack of nitrogen, which we did by applying fertilizer. This project was particularly interesting for us because it was the first time we worked with trout at such a shallow water depth. We managed not only to achieve our goals, but also to gain valuable experience for future projects. #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen

The present work showed the ability of the Chlorella vulgaris to use valuable resources derived from industrial cultivations of basiland tobacco in a hydroponic deep-water culture system. Although the use of spent hydroponic solutions slightly affected the microalgal biomass accumulation of more than ~40 % compared to the fresh solution, possibly due to the presence of root exudates that have an antagonistic effect toward microalgae, the phytoremediation activity of microalgae was achieved. The reported results described the consumption of more than 80 % and 70 % of P and N residual nutrients in hydroponic formulations, respectively. https://lnkd.in/gdnypHDb #microalgae #chlorella #aquaculture #sustainability #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen #circulareconomy

Successful pond remediation with chlorella from Algotec   Today we would like to share another successful water body remediation project with the help of Algotec Aqua. Problem: The client came to us with serious problems – strong blooming of the pond, unpleasant smell and algae covering 40% of the water surface. Solution: We calculated the required amount of Algotec Aqua and developed a customized methodology to restore the balance of the aquatic ecosystem.   Process and Results: Day 1: First application of Algotec Aqua. Day 3: Noticeable change in water clarity and significant reduction in algae on the surface. Day 5: Almost complete cleansing of the water surface and disappearance of unpleasant odor.   Our client sent us photos of the water body before Algotec Aqua application, after 3 days and 5 days after the first usage. You can see for yourself the results of chlorella work and evaluate the changes in the water body on the attached photos. #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen 

The inclusion of Chlamydomonassp. in the diet had a significant positive impact on the fatty acid and amino acid profile of whole common carp. Present data revealed that substituting a portion of fishmeal with Chlamydomonas sp. powder could provide higher growth performance, offering both nutritional benefits and higher survival rate in common carp (Cyprinus carpio). !!! However, the economic efficiency of using dry microalgae for aquaculture is still very difficult. Taking into account this and our extensive experience in the use of live microalgae for the intensification of freshwater fish farming, it is currently a more rational and approved scenario https://lnkd.in/ehqrCbfS #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen

Chlorella vulgaris can be used to replace until 3% of soybean meal in diets for broiler chickens without negative implications, while positively affecting breast meat color according to consumers’ preferences. Due to our experience of trial application LIVE microalgae for livestocks as a part of feeding system we got the next conclusions: reduction mortality of young animals and increasing weight gain of cattle, pigs and broilers by 30% or more; increasing in the number of pigs by 18%; increasing in cow milk yields by 15-25%; with increased feed digestibility, savings of 15 per cent or more can be made on feed consumption. However, the are a plenty of details of microalgae implementation into livestocks equipment. #microalgae #chlorella #sustainability #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen #feedsupplements #lifescience #agritech https://lnkd.in/eEj_bRBz

In this study, the effect of using Chlorella sorokiniana in place of some fishmeal in the diet was evaluated on the farming of Pacific white shrimp (Litopenaeus vannamei) at different stocking densities. The results showed that dietary chlorella was effective in improving growth performance, immunity, intestinal health and disease resistance of shrimp, and this improvement effect is more obvious at high stocking density. In addition, at high stocking densities, dietary chlorella may also result in good synergistic relationships between immune and metabolic genes and intestinal beneficial bacteria to jointly promote shrimp growth and maintain shrimp health. This finding demonstrates that chlorella has great potential as a protein source in intensive farming of shrimp. #microalgae #chlorella #aquaculture #shrimp #shrimpfarming #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen https://lnkd.in/eJJKxRcB

Chernomorets water body, Saratov On April 21, 2024 our client began preparations for the spring-summer season 2024. This pond is the most diverse pond in the whole Saratov region, which is home to silver carp, carp, catfish and sturgeon. The pond is overcrowded, stressed due to the large number of fish, which leads to the process of rotting and waterlogging. Additional stress is created by fishermen by introducing fish bait into the reservoir. This is the fourth season our client has been using Algotec's Chlorella. This season, together with Algotec Aqua, we decided to introduce Algotec Split into the pond to fight silt deposits and unpleasant odors from the pond. And Algotec Aqua helps fight blue-green algae and increases oxygen levels in the water body. Results: -      Absence of cyanobacteria blooms -      Clean and clear water -      High oxygen level -      Excellent bite! Thanks to our products, the Chernomorets reservoir remains ecologically clean and attractive for fishing. #microalgae #chlorella #aquaculture #sustainability #fishfarming #fishfeed #wastewatertreatment #zeroemission #carbonneutrality #carboncapture #bioremediation #environmentprotection #freshwater #bioreactors #oxygen
