Marine biological erosion and corrosion are significant economic barriers to the development of competitive aquaculture globally. Therefore the application of economically viable and especially environmentally friendly methods to prevent marine corrosion and erosion and minimise the aquaculture environmental impact is a constant and pressurizing business need worldwide. Addressing cost-effectively this need HealthNet proposes the isolation of anti-corrosion agents from marine organisms such as micro- and macro-algae. Algae have the potential to produce a variety of biologically active compounds with antibacterial, antifungal, anti-corrosion effect, which can potentially be the solution to prevent marine erosion and corrosion. The majority of these substances belong to the groups of lipopeptides, amides, terpenoids, lactones, pyrrole and steroids. Moreover the application of these substances and their encapsulation into the aquaculture nets, it is achieved by a coating agent based on a proteinaceous glue of marine biological origin, where the corrosion inhibitors will be encapsulated. The development of the proposed overlays is a global innovation.


Describe the problem your company wishes to solve and how your product or service will solve it


Marine biological erosion and corrosion is a complex problem, defined as the undesirable deposition and accumulation of organisms in aquaculture nets which are immersed in the marine environment. This unfavourable condition results in progressive stress on the equipment due to the extra weight of the corrosive organisms deposited. Also, marine colonies that grow on the aquaculture nets are directly competing with the cultivated organisms for food, and they main disease causes of the cultivated organisms. In addition, these colonies produce secondary metabolites, which are toxic to the cultivated organisms, and also cause deoxygenation in the aquaculture space by preventing the exchange of oxygen, water and fish waste.


The incurred costs associated with marine biological erosion and corrosion are significant, since net replacement, production losses and quality and growth rate of the cultivated organisms are huge and constitute a major financial risk for aquaculture worldwide.


The most commonly used methods of preventing and controlling the problem in Europe are mechanical cleaning and anti-fouling coating. The first method requires work intensity and it is quite laborious, time consuming, costly, and ineffective in most cases.


On the other hand, the coating of the surface of the aquaculture nets with biocidal agents is a widely used method and relies on the release of small amounts of active substances that prevent the growth of corrosive organisms and destroy existing ones. This technique has significant drawbacks as coatings have a short shelf life, increased cost, and corrosion inhibitors currently used are known sources of aquaculture contamination. Copper (Cu2O) and zinc pyrithione are the main ingredients of biocide coatings. However, the use of copper and zinc in fish farms is undesirable because these metals are included in the EU Dangerous Substances Directive, which recognizes their toxicity to aquatic organisms and the long-term adverse effects on the environment.


The extensive use of copper for anti-erosion purposes has raised concern about the negative but also fatal consequences for the farms. Based on researches carried out in Greece, particularly in the Ionian and Aegean Sea crops, it has been shown that the use of copper and zinc in anti-corrosion paints leads to the accumulation of heavy metals in the liver of farmed fish. For this reason, the legislation in Europe (Biocides Directive EC 98/8 / EC) greatly restricts the use of toxic anti-corrosion coatings.


Thus HealthNet is a most competitive and innovative solution for aquaculture farms globally. Where, marine biological corrosion will be eliminated with coating the nets with marine biological origin agent. This totally environmentally friendly anti-fouling agent contains a variety of biologically active compounds with potent antibacterial, antifungal, anti-corrosion effect extracted from micro- and macro-algae.


It has been scientifically recorded that marine algae such as Cyanobacteria, Chlorophyceae, Rhodophyceae, Phaeophyceae, Dinophyceae and Chrysophyceae are producing a wide variety of substances that are quite effective naturally produced antifouling agents for HealthNet use. In particular, HealthNet achieves the following:


1.       Efficient recovery of environmentally friendly anti-corrosion and antimicrobial agents from macro- and micro-algae.


2.       Applications of techniques for enriching the mined extracts to substances of interest.


3.       Entrapment of anti-corrosion and antimicrobial agents of marine origin to improve their service life and their potency


4.       Development of new coating techniques for aquaculture cages


5.       Use of innovative, and environmentally friendly antifouling agents and methods for aquaculture farming


HealthNet adoption in aquaculture farming results in immediate financial return and achieves high ROI, while it ensures regulatory compliance, and stable high quality production.


For sure, HealthNet significantly improves aquaculture fish health since eliminates specific health hazards (associated with marine biological matter deposition on aquaculture nets) and improves the living conditions of farming fish by enabling a free water circulation within net cages.

Thanks Khalil. HealthNet project did not achieve to gather 20 votes to progress to the next stage of NFTC competition. I hope the other project of our company (FruitFeed) to have better chances for a good placement.
Thanks again for your encouragement.
