观赏鱼白点病的病因探讨及防治策略研究

摘  要

本文综述了观赏鱼白点病的相关概述、影响病原体感染的因素、病因探讨及防治策略。白点病作为一种常见的观赏鱼寄生虫疾病，由多子小瓜虫引起，主要通过水体传播，导致鱼体皮肤出现白点、色素失调等典型症状。该病的流行与病原体特性、环境因素、宿主免疫状况及病原体自身因素密切相关。研究指出，免疫力低下、水体中营养物质过剩、污染物传播及继发感染是观赏鱼白点病的主要病因。为有效防治该病，本文提出了加强饲养管理、降低水体营养物质浓度、隔离病鱼及药物治疗等策略。这些策略旨在改善养殖环境，提高鱼体免疫力，减少病原体传播，从而达到预防和治疗白点病的目的。本研究为观赏鱼白点病的防治提供了理论依据和实践指导，有助于降低养殖损失，促进观赏鱼养殖业的健康发展。

Abstract

This paper summarizes an overview of white spot disease, factors affecting pathogen infection, etiology and prevention strategies of ornamental fish. As a common parasitic disease of ornamental fish, white spot disease is caused by many small melons and mainly transmitted through water, leading to typical symptoms such as white spots and pigment imbalance in fish skin. The prevalence of the disease is closely related to pathogen characteristics, environmental factors, host immunity status and pathogen own factors. The study pointed out that low immunity, excess nutrients in water, transmission of pollutants and secondary infections are the main causes of white spot disease in ornamental fish. In order to effectively prevent and control the disease, this paper proposes strategies such as strengthening feeding management, reducing the concentration of nutrients in water, isolating sick fish and drug treatment. These strategies aim to improve the farming environment, improve fish immunity and reduce pathogen transmission, thus achieving the purpose of preventing and treating white spot disease. This study provides theoretical basis and practical guidance for the prevention and control of white spot disease in ornamental fish, which helps to reduce breeding losses and promote the healthy development of ornamental fish breeding industry.

Keywords：White spot disease in ornamental fish, etiology and control strategy
