Nowadays, more than 50% of the fish and crustaceans present in our food come from hatcheries. This sector is a young and fast-growing industry that faces different challenges compared to other animal productions. Through its specialized business unit, DOMCA offers unique products to support the sustainable and profitable growth of its customers in this sector.

Problematic with today’s aquaculture

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 help to improve fish health conditions, both in inland and offshore aquaculture. Therefore, the AQUAgarlic range has been developed through a specific approach for this sector, combining basic research in our highly specialized laboratory (DMC Research Center) together 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:

  • Our products are characterized by high stability, which ensures long shelf life and high thermal and oxidation resistance.
  • All our products are subject to a strict quality control that guarantees the same concentration of active ingredients in all batches.
  • We have several types of products (liquid and powder). Contact our technical staff who will advise you on which is the one that best suits your needs.


AQUAgarlic range products are an aromatic/flavoring premix for organoleptic additives intended for animal feed, specifically developed 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 ingredients of garlic and onion support the health of the intestinal flora and have scientifically proven antioxidant and anti-inflammatory properties, as well as stimulating the immune system.

AQUAgarlic A Pro

Functional feed additive based on alliaceae-derived compounds (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 obtained from alliaceous plants.

AQUAgarlic A Pro, which is a product highly rich in this type of organosulfur compounds, could be used as a further support for the 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 with the aim of validating the previous results observed in vitro. Thus, the results of the efficacy of AQUAgarlic A Pro in challenge studies in rainbow trout, under controlled laboratory conditions are shown below.

AQUAgarlic P Protec

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 efficiency to resist parasitic infections.


  • Reduced mortality caused by branchial damage.
  • Improved performance and productivity.
  • Reduction of gill parasite counts by reducing the frequency of bathing treatments.
