Today, more than 50% of the fish and crustaceans in our food come from hatcheries. This sector is a young and fast growing industry that faces different challenges compared to other animal production. Through its specialized business unit, DOMCA offers unique products to support the sustainable and profitable growth of its customers in this sector.
Bacterial diseases and parasitic infestations are a very serious risk to the sustainability and profitability of aquaculture production worldwide. DOMCA has developed an innovative range of exclusive natural additives for aquaculture feeds to reduce the impact of these problematic outbreaks for the aquaculture farmer.
The aim is to ensure that these products contribute to the improvement of fish health conditions in both inland and offshore aquaculture. Therefore, the AQUAgarlic range has been developed through a specific approach to this sector, combining basic research in our highly specialized laboratory (DMC Research Center) with field studies in collaboration with our customers. DOMCA’s product range is based on natural compounds and contributes to reduce the use of antibiotics and chemicals in aquaculture.
The AQUAgarlic range offers products rich in organosulfur compounds that improve the performance of aquaculture farms and are suitable for all species:
The AQUAgarlic range of products is an aromatic/flavoring premix for organoleptic additives for animal feed, specifically designed for aquaculture to increase the feed intake of fish.
Formulated from plant extracts (garlic and onion), it is a standardized product, stable to feed processing conditions and produced under FAMI QS certification. The phytochemical components of garlic and onion support healthy intestinal flora and have scientifically proven antioxidant, anti-inflammatory and immune stimulating properties.
Functional feed additive based on compounds derived from Alliaceae (organosulfur compounds) to reduce the impact of bacterial pathogens on fish and shrimp productivity by promoting a healthy gut microbiota, resulting in improved animal performance and health.
In vitro studies conducted at the DMC Research Center laboratory have shown that certain important challenges in the aquaculture industry, such as mortality associated with certain bacteria, could be reduced by using bioactive compounds derived from alliaceous plants.
AQUAgarlic A Pro, a product highly rich in this type of organosulfur compounds, could be used as a further support for fish farmers in the prevention of infectious diseases in aquaculture, along with such important areas in the sector as the use of high quality eggs, fish genetics, species-appropriate nutrition or animal management.
However, in order to demonstrate the efficacy of these products, it is necessary to carry out in vivo studies to validate the previous results observed in vitro. Therefore, the results of the efficacy of AQUAgarlic A Pro in challenge studies with rainbow trout under controlled laboratory conditions are presented below.

Functional feed additive used to reduce the impact of monogenic branchial parasites on fish productivity and survival. It stimulates the immune competence of fish and their ability to resist parasitic infections.
