Medicinal herbs: The missing link to sustainable aquaculture

Aquaculture, given its direct role in the human diet, mandates strict quality assurance and health protocols. Healthy fish require a strong immune system to defend themselves from a broad spectrum of pathogens such as bacteria, viruses, and parasites. Stimulating the immune system is a prevalent measure taken to ensure satisfactory immune response and disease control. Measures against disease outbreaks are available, such as chemoprophylaxis with vaccines, chemical therapeutics, and antibiotics. All of which, alongside their benefits, pose certain risks to the fish’s habitat and itself. Natural substances extracted from herbs or their parts (roots, leaves, etc) tend to be the most effective therapeutics with the least adverse effects. In this study, natural remedies have been discussed as a potent method of preventive care in aquaculture.

On the issue of Australian crayfish cultivation in ponds to ensure sustainable aquaculture development

The authors of this article describe the experience of biotechnology for growing Australian crayfish in conditions of pond cultivation in a group of ponds, operating in an intensive mode, used in an isolated area close by a natural water source in the Astrakhan region. In the presented article, research is aimed to clarify the main biotechnological indicators that increase the efficiency of cultivation in pond conditions. The conditions of transportation, the duration of transportation, and the density of crayfish in ponds with an area of 1 hectare have been clarified. The presented food recipe with the specification of the percentage of nutrients as additional feeding, organized when growing in ponds according to the food recipe itself, increases not only the growth rate but also the hemolymph protein concentration, which indirectly proves the satisfactory conditions for keeping aquaculture objects. Monitoring for the biotechnology of growing Australian crayfish in pond conditions: own developed food recipe, biological and physiological testing of key indicators such as hydrochemical indicators of water, hydrobiological indicators of the concentration of, and physiological indicators for determining the so-called biotechnological norm, which will add additional missing information on this aquaculture object.

Aquaculture constitutes an alternative source for food production and contributes to the reduction of indiscriminate catch of aquatic organisms from their natural environment (Diaz & Neira, 2005; Beveridge et al., 2013). However, high mortality during larval state remains a challenge in this sector, mainly because of factors like diets and diseases induced by pathogens (Helvik et al., 2009; Stentiford et al., 2017). Therefore, growth and health management is a key strategy for sustainable aquaculture (Martinez et al., 2016a).
