The global growth of farmed shellfish production has resulted in considerable research investigating how biofouling compromises farm productivity. Shellfish fitness can be compared between fouled stock and stock which has undergone treatment. As treatment options are often harsh, they may deleteriously affect stock. The projected impact of biofouling may therefore be confounded by the impact of treatments. Given the substantial cost of fouling removal, some have questioned the necessity of biofouling mitigation strategies. Meta-analysis revealed that biofouling typically reduces shellfish fitness. However, the fitness of treated stock was often lower or equal to fouled control stock, indicating that many common antifouling (AF) strategies are ineffective at enhancing farm productivity. Overall, caution and diligence are required to successfully implement biofouling mitigation strategies. The need remains for increased passive prevention approaches and novel AF strategies suitable for shellfish culture, such as strategic siting of bivalve farms in areas of low biofouling larval supply.
养殖贝类产量在全球范围内的增长引发了大量研究，旨在探究生物污损如何影响养殖生产力。可以对受污损的贝类种群与经过处理的贝类种群的健康状况进行比较。由于处理方法通常较为严苛，可能会对贝类种群产生有害影响。因此，生物污损的预计影响可能会与处理的影响相互混淆。鉴于去除污损的成本高昂，一些人质疑减轻生物污损策略的必要性。荟萃分析表明，生物污损通常会降低贝类的健康状况。然而，经过处理的贝类种群的健康状况往往低于或等同于受污损的对照种群，这表明许多常见的防污（AF）策略在提高养殖生产力方面无效。总体而言，成功实施减轻生物污损策略需要谨慎和勤勉。仍需要增加被动预防方法以及适用于贝类养殖的新型防污策略，例如将双壳类养殖场战略性地选址在生物污损幼虫供应较低的区域。
