Summary

Generalized cowpox infection in the Patagonian cavy may represent a threat to the health of immunocompromised persons. We report the first case of cowpoxvirus infection in the Patagonian cavy in an educational animal park. The mara developed extensive pox lesions, shedding large amounts of viral particles. The ending of vaccination programmes against smallpox in the late 1970's may lead to an increase in susceptibility of humans to zoonotic poxviruses.     

鱼类细胞培养及其在病毒学研究中的应用

鱼类细胞培养技术作为一种重要的研究和应用技术方法,自1962年发展至今,已建立了超过220个株系。鱼类病毒学是其应用最为广泛的领域。论文主要就鱼类细胞的主要株系、我国鱼类细胞培养的发展以及鱼类细胞株系对于鱼类病毒的分离、鉴定、增殖及病毒病防控研究做一综述,以期对水产动物的疾病防控具有一定的指导意义。     

牛磺酸在鱼类营养中的作用及其在鱼类饲料中的应用

牛磺酸是维持鱼类正常生理功能的营养物质之一,在鱼类营养中有着非常重要的作用.本文综述了牛磺酸的性质与分布、合成与代谢、营养生理功能及鱼类牛磺酸的需要量及其在鱼类饲料中的应用.     

鱼用饲料与鱼类健康

长期以来．多数水产养殖工作者习惯以“无病即是健康”来理解养殖鱼类的健康状态。但未发病的鱼并不表明其必定是健康的。因为疾病的发生与否是与宿主、病因(病原)和环境条件三要素密切相关。其中任何一个因素的存在与否或作用力的强弱变化，即可决定疾病是否能发生或导致疾病的终止。如养殖水体中不存在某些病原体。或者环境条件并不适合病原的孳生和繁衍，     

Fish and amphibian anesthesia.

This article is designed to provide the veterinary practitioner with some basic information on how to anesthetize fish and amphibians. General guidelines regarding working with these aquatic animals are covered. Specific topics include methods of anesthetic delivery, anesthetic monitoring, and recovery. Various anesthetic regimes and dosages are presented both in the text and in table form.     

对罗非鱼小鱼制备鱼粉的探讨

[目的]为了开发罗非鱼小鱼资源,利用罗非鱼小鱼直接制备鱼粉.[方法]对相应鱼粉的主要营养成分和蛋白质胃蛋白酶消化率进行了测定.[结果]小于100 g罗非鱼鱼粉的主要营养成分和蛋白质胃蛋白酶消化率达到了特级鱼粉的质量要求.[结论]利用罗非鱼小鱼生产鱼粉的方案可行,鱼鳞粉蛋白质含量、胃蛋白酶消化率虽不及罗非鱼鱼粉,但可以充当配合饲料使用,使营养更加均衡.     

鱼品种及加工方式对鱼粉质量的影响

<正>我国的国产鱼粉产量约为30万吨,主要集中在山东荣成,浙江舟山、石浦,辽宁大连等地生产,但国产鱼粉产量不能满足饲料企业的需求,因此每年我国都从国外进口大量鱼粉。南美国家智利和秘鲁是主要的鱼粉生产国家,秘鲁与智利的鱼粉占全球鱼粉生产国家的比率分别为29%和20%,2009年秘鲁鱼粉总出口量约为148.72万吨,2009年我国共进口秘鲁鱼粉73万吨,进口智利鱼粉34万吨,其他国家鱼粉总量为23.8万吨。     

鱼粉市场：预计国内港口货吃紧，进口鱼粉已有利可图

由于受禁捕影响,上周(至4月8日)的鱼获量只有134900MT,正如我们预测,其中大部份(约75200MT)用于生产蒸气鱼粉,而只有51700MT用于生产普通鱼粉。与2000年同期比较鱼获量共少了28%。秘鲁于本月10日已解禁,初步得到的消息,捕鱼获量还算不错。 有利因素 1.国内存货随用量的扩大而在逐步减少,估     

Fish meal--nutritive value

Understanding the interactions between nutrition and immune system is crucial for adjusting nutrient allowances in dietary formulations that optimize production efficiency. Among various animal proteins, fish meal (FM) is rich in protein (amino acids), readily available throughout most of the world, and competitively priced against other animal proteins (e.g. milk and blood). In addition, many researchers reported that FM is traditionally recognized as a high digestible protein with a high content of amino acids, vitamins and minerals for pigs. Supplementation of fatty acids by FM and fish oil (FO) is one strategy to modify an animal immune response. As a result of FM and FO effects, those supplementations can result in improved performance and immunity of young animals.     

Clinical Anesthesia and Analgesia in Fish

Fish have become a popular experimental model and companion animal, and are also farmed and caught for food. Thus, surgical and invasive procedures in this animal group are common, and this review will focus on the anesthesia and analgesia of fish. A variety of anesthetic agents are commonly applied to fish via immersion. Correct dosing can result in effective anesthesia for acute procedures as well as loss of consciousness for surgical interventions. Dose and anesthetic agent vary between species of fish and are further confounded by a variety of physiological parameters (e.g., body weight, physiological stress) as well as environmental conditions (e.g., water temperature). Combination anesthesia, where 2 anesthetic agents are used, has been effective for fish but is not routinely used because of a lack of experimental validation. Analgesia is a relatively underexplored issue in regards to fish medicine. However, recent studies have investigated opioid agents, nonsteroidal antiinflammatory drugs, and local anesthetics to determine their efficacy in minimizing pain and discomfort. The opioid morphine and the local anesthetic lidocaine do have significant effectiveness in reducing pain-related responses in rainbow trout (Oncorhynchus mykiss). Studies aimed at developing reliable analgesic protocols should explore a wide range of analgesic drug classes in several fish species.
