摘要

作为伴侣动物饲养或在公共水族馆展示的活观赏鱼的全球年贸易额估计为 150 亿至 200 亿美元。与作为食用鱼养殖的鱼类相比,观赏宠物鱼类的供应链往往涉及更多方面,在每个阶段,鱼类都会面临压力,包括处理、圈养、拥挤、机械干扰和水质差。如果长期受到这些压力,会损害鱼类的免疫系统,使其更容易感染病原体。传染病造成的死亡率和发病率会对鱼类养殖业造成巨大的福利影响和经济损失。然而,这些疾病的治疗并不简单,各行各业的做法大相径庭,而且有几种方法会产生意想不到的后果,例如出现抗性病原体菌株。虽然针对少数鱼类物种(如锦鲤、金鱼)的疾病治疗方法得到了重点研究关注,但对于家庭水族馆主来说,他们越来越依赖于天然化合物产品,而这些产品受到的科学关注却少得多。本综述旨在强调我们在观赏宠物鱼类贸易中使用的一系列疾病治疗方法方面的知识差距,尤其关注用于家庭水族馆的淡水热带鱼种。文章考虑了这些治疗方法可能引起的问题,包括微生物抗药性以及治疗方法本身对鱼类健康和福利的影响。

Current disease treatments for the ornamental pet fish trade and their associated problems

The trade in live ornamental fishes to be held as companion animals or displayed in public aquaria has an estimated global annual value of US$15–20 billion. Supply chains for ornamental pet fishes often involve many more parties than for fish farmed as food fishes, and at each stage, fishes are exposed to stressors including handling, confinement, crowding, mechanical disturbance, and poor water quality. If chronic, these stressors can compromise their immune system, making fishes more susceptible to pathogens. Mortality and morbidity from infectious disease can result in considerable welfare impacts and massive economic losses for the industry, and the range of infective agents seen in ornamental species is well documented. However, treating these diseases is not straightforward with practices varying greatly across the trade and with several approaches having unintended consequences, such as the emergence of resistant strains of pathogens. While disease treatments for a handful of fish species (e.g., koi, goldfish) have received focused research attention, for the home aquarium owner, there is an increasing reliance on products based on natural compounds which have received far less scientific attention. This review aims to highlight the gaps in our knowledge surrounding the range of disease treatments used across the ornamental pet fish trade, with a particular focus on freshwater tropical species destined for home aquaria. Consideration is given to the potential problems arising from these treatments, including microbial resistance and effects of treatments themselves on fish health and welfare.

期刊介绍: Reviews in Aquaculture is a journal that aims to provide a platform for reviews on various aspects of aquaculture science, techniques, policies, and planning. The journal publishes fully peer-reviewed review articles on topics including global, regional, and national production and market trends in aquaculture, advancements in aquaculture practices and technology, interactions between aquaculture and the environment, indigenous and alien species in aquaculture, genetics and its relation to aquaculture, as well as aquaculture product quality and traceability. The journal is indexed and abstracted in several databases including AgBiotech News & Information (CABI), AgBiotechNet, Agricultural Engineering Abstracts, Environment Index (EBSCO Publishing), SCOPUS (Elsevier), and Web of Science (Clarivate Analytics) among others.
