Could Carp-Care Products Be Doing More Harm Than Good? It's a question that angler Chris Young and his team at De Montfort University are asking, and their research has some surprising findings. Young, an Associate Professor of Molecular Medicine, and his colleague Omar Qutachi, decided to investigate the effectiveness and safety of carp-care products after a personal experience. While fishing with his son, Jake, Young found himself with a wounded fish and a bottle of carp-care solution. However, upon realizing the product lacked an ingredient list, he chose not to use it. This incident sparked their study, which aimed to gather empirical data on the products' effectiveness against carp pathogens. The study, conducted with the help of the Institute of Fisheries Management (IFM), involved testing 11 market-leading carp-care products against a panel of pathogens harmful to carp. The results were eye-opening. Many products showed no antimicrobial effects, and those that did were highly toxic to carp cells, posing ecological risks due to their high concentration. Propolis, a widely accepted market leader in wound care, was found to be detrimental to fish due to the solvents it was dissolved in. Ethanol and methanol stripped mucin, a primary element in fish slime, and created holes in the skin, making the fish more susceptible to pathogens. This raises a deeper question: are we doing more harm than good by using these products? At many fisheries, carp-care products are mandatory, and there are anecdotal reports of fish being treated and then caught again with healed wounds. However, Young dismisses these observations as insufficient evidence. He explains that carp are hardy creatures with robust immune systems, and in clean environments, the focus is more on sealing and healing wounds than on infection. He emphasizes that applying carp-care products to potentially non-infected wounds can delay healing due to their toxicity to regenerating fish cells. Young and Qutachi are keen to highlight that their study does not aim to blame individual products or companies. They believe there is a lack of scientific process in the development of these products, and they want to engage with policymakers, regulatory agencies, and legislators to encourage collaboration with scientists. The team is already working with the IFM and Angling Trades Association (ATA) to develop an approved standard with an agreed testing procedure for products. They aim to provide companies with the tools and resources needed to create effective and safe carp-care solutions. Young envisions a phased transition to better products, encouraging brands and fishery owners to contact him for advice and stay informed on developments. He believes that by engaging with scientists, the industry can move away from unsafe products and improve the situation for angling. In conclusion, the study raises important questions about the effectiveness and safety of carp-care products. It highlights the need for scientific scrutiny and collaboration to ensure that angling practices are not inadvertently causing harm to fish and the ecosystem. As Young and his team continue to develop a solution, the angling community can look forward to safer and more effective ways to care for their carp.
