Abstract

With the growing world population, the demand for food has increased, leading to excessive and intensive breeding and cultivation of fisheries, simultaneously exacerbating the risk of disease. Recently, shrimp producers have faced major losses of stocks due to the prevalence of periodical diseases and inappropriate use of antibiotics for disease prevention and treatment, leading to bacterial resistance in shrimp, along with imposing health hazards on human consumers. Strict regulations have been placed to ban or reduce the use of prophylactic antibiotics to lessen their detrimental effects on aquatic life. Dietary and water supplements have been used as substitutes, among which probiotics, prebiotics, and synbiotics have been the most beneficial for controlling or treating bacterial, viral, and parasitic diseases in shrimp. The present analysis addresses the issues and current progress in the administration of pro-, pre-, and synbiotics as disease controlling agents in the field of shrimp farming. Furthermore, the benefits of pro-, pre-, and synbiotics and their mechanism of action have been identified such as; strengthening of immune responses, growth of antibacterial agents, alteration in gut microflora, competition for nutrients and binding sites, and enzymes related activities. Overall, this study aims to depict the antagonistic action of these supplements against a variety of pathogens and their mode of action to counter diseases and benefit shrimp species.

摘要

随着世界人口的增长,对食物的需求增加,导致渔业的过度和集约化养殖,同时加剧了疾病的风险。最近,由于周期性疾病的流行和抗生素在疾病预防和治疗中的不当使用,虾类养殖者面临着库存的重大损失,导致虾类产生细菌耐药性,并对人类消费者的健康构成威胁。已经出台了严格的规定来禁止或减少预防性抗生素的使用,以减轻它们对水生生物的有害影响。已经使用了饮食和水补充剂作为替代品,其中益生菌、益生元和合生菌最有利于控制或治疗虾类的细菌、病毒和寄生虫疾病。本分析探讨了在虾类养殖领域中将 pro、pre 和 syn 作为疾病控制剂管理的问题和当前进展。此外,还确定了 pro、pre 和 syn 的益处及其作用机制,例如:增强免疫反应、生长抗菌剂、改变肠道微生物群、竞争营养物质和结合位点以及相关酶的活性。总的来说,本研究旨在描述这些补充剂对各种病原体的拮抗作用及其作用方式,以对抗疾病并使虾类受益。
