在水生观赏动物的人工育苗中,幼体阶段的活饵料是育苗成功的关键之一。本文着重探讨了轮虫(如褶皱臂尾轮虫)、卤虫、桡足类(如日本虎斑猛水蚤、哲水蚤等)、枝角类(如蒙古裸腹涵和西藏拟泾)等饵料浮游动物的营养特点、培养利用现状及其在水生观赏动物养殖中的应用前景。为水生观赏动物养殖中活饵料使用和开发新的饲料蛋白源提供参考。  相似文献

This study examines whether people with disabilities(PWD) participate in leisure and travel activities with their desired companions and if there are discrepancies between their social networks and real recreation companions. The recreation companionship and travel behaviour of PWD have not been thoroughly explored, particularly in non-Western contexts. Accordingly, data were collected from 494 respondents in South Korea, and findings suggest that there was a significant gap between companions PWD desire and those they actually maintain. Travel and tourism were the least frequent recreation activities for PWD. The results can provide managerial implications regarding practices of inclusive and accessible tourism.  相似文献

Pets factor into the daily decision-making of many people. Importantly, various characteristics of these human–animal relationships are known to strongly influence pet owners’ risk behaviour and, consequently, their animals’ welfare during disasters. Yet, few studies have examined a range of such characteristics concurrently in order to describe risk propensity differences in these relationships. In this study, 437 Australian companion-animal (pet) owners reported human–animal relational, personality and attitudinal characteristics, to examine differences in stated tendency to act to secure their pet’s welfare whilst risking potential harm in a hypothetical disaster dilemma. Cluster analysis identified five archetypal profiles differing in relational, personality, attitude and risk-propensity characteristics, as well as in stated willingness to risk personal safety for the well-being of a pet. Results suggest that relational archetypes are an effective means of examining pet–owner risk propensity, to better understand owners’ risk-taking to protect their animals from harm during a disaster.  相似文献

The vast majority of academic articles, according to eminent literary critic John Sutherland, read like they're written by robots in a Japanese car factory. And that a Toyota-style recall is sorely needed. This statement may or may not be true, but many scholars would surely concede that remedial writing measures are necessary. This paper describes one such measure, an illustrated novel that's similar to Shrek, only with advertising characters like the Michelin Man instead of fairytale characters like the Gingerbread Man. After an apt introductory anecdote, the rationale for The Penguin's Progress is explained, the difficulties surrounding its creation are itemised, and an extract from the work-in-progress is presented.  相似文献

In May 2009, during a period of rising political polarization in Thailand, a cub was unexpectedly born in Chiang Mai's Zoo to a pair of Chinese pandas. The authorities used the occasion to boost the crisis-ridden tourism to the northern Thai city, instigating an unprecedented national craze around the tiny cub, and promoting a massive pilgrimage of domestic visitors to the zoo. In a conspicuous act of protest against the prioritization of the foreign pandas, some elephant keepers in the Ayutthya kraal, painted their animals in panda colors, leading to an implicit contest between the two animal icons. In this case study, the wider theoretical and comparative implications of that contest are analyzed. Whereas previous studies of tourists engagement with captive wild animals paid scant attention to its wider social context, the article examines the cultural and economic background of the contest, and the manner in which it became implicated in the process of political polarization between the societal center and the periphery.  相似文献

汉语可用含有幼小意义的词头或词尾构成动物幼体的名称,也可用专有名词来指称。英语除可用某些含有幼小意义的词汇加名词构成幼小动物的名称,还可用加前缀或后缀的方法构成新词指称幼小动物。同汉语一样,英语中也有大量的专有名词指称幼小动物,不同之处在于,汉语中一种动物的幼仔一般只有一个名称,而英语中某些动物的幼仔可有数个不同的名称,同一名称也可指称不同的幼小动物。  相似文献

改革开放以来,我国的畜牧养殖业发展迅速,养殖的规模越来越大,对推动经济发展、促进食品生产加工繁荣起到了非常重要的促进作用。但与此同时,畜牧养殖过程中也会因为技术、环境或人为等因素的影响而导致养殖的动物感染疫病,不仅会给养殖管理增加了难度与工作量,还会因为动物疫病的隐藏性、传染性,以及检验检疫过程中出现的疏漏,给下游的食品生产加工质量带来直接影响,进而影响消费者的身体健康。所以,加强对动物养殖生产环节的检验检疫力度与质量,是保证食品源头安全的重要手段。  相似文献
