广东省养蛇业的现状与发展策略的研究 总被引:1,自引:0,他引:1
目的探讨广东省蛇类养殖业的现状与发展的策略方法在全省范围内按各市县养殖场逐个进行实地考查,调查蛇类养殖场的分布、规模、面积、养殖技术和投资金额以及蛇的种类、数量、来源和贸易情况,分析蛇类养殖存在的问题和经营利用的可能性。并以表格的形式搜集各养蛇场的基础资料、近年来的养殖情况及意见和建议。结果3个养殖最成功的蛇场饲养的主要蛇种类有眼镜蛇、眼镜王蛇、滑鼠蛇、乌梢蛇,目前已基本上解决了蛇类养殖的难题,掌握了蛇类冬眠和管理等关键技术,蛇类存栏量都达到10万条以上,存栏的个体都在第三代以上;养殖成本明显下降,经济效益可观。结论眼镜蛇、眼镜王蛇、滑鼠蛇、乌梢蛇是人工养殖成功的种类,提出发展我国蛇类产业的具体措施和策略,为蛇类养殖产业化、规模化和集约化提出合理化的建议。 相似文献

蛇是有多种经济用途的野生动物,近年来市场需求量越来越大,捕捉野生蛇类受到资源的限制,驯养蛇类已成为快速致富的重要途径。蛇类驯养成功的关键在于蛇园的拟态程度。目前我国多采用蛇房与蛇园分离的结构,这种结构虽然便于蛇类捕捉,但增加了投资,且与野生蛇类的生境结构有较大差别,不利于蛇的驯养。我们设计蛇房假山一体化结构的蛇园,很好地解决了上述问题,现介绍如下。1 蛇房假山一体化结构 蛇房假山一体化是将蛇房与假山建在一起。蛇房建在园内蛇的活动区,内部建造成蛇窝供蛇避暑、冬眠、休息及藏身。蛇房的外围堆垫土层,… 相似文献

云开脊蛇(Achalinus yunkaiensis)之前仅在广东和广西有分布报道。本文基于形态比较及线粒体COI基因序列分子系统关系分析结果,确定采集于湖南省新宁县的1号雌性脊蛇标本(CIB 119041)为云开脊蛇,为湖南省新记录种。该标本鼻间鳞沟约等于前额鳞沟,上颔齿24枚;背鳞通身23行,腹鳞150枚,尾下鳞55枚;尾长与体长之比为0.203。至此共有4种脊蛇分布于湖南省。此外,本文还报道了棕脊蛇(A. rufescens)1号雄性地模标本(CIB 119042),该标本鼻间鳞沟长于前额鳞沟;背鳞通身23行,腹鳞153枚,尾下鳞62枚;尾长与体长之比0.201。分子系统发育结果显示,棕脊蛇种组各支系的系统地位还需进一步研究厘定。 相似文献

正2013年4月20日,在湖南省宜章县莽山国家级自然保护区崖子石片区高山矮林(24°58'603″N,112°58'314″E,海拔1 500 m)林下一处岩石旁采集到1条游蛇科(Colubridae)幼蛇标本。依据形态学特征(赵尔宓2006,李操等2009),该蛇鉴定为方花丽斑蛇(Maculophis bellus),这是该蛇种自1982年在莽山大塘坑首次记录报道(梁启燊等1982)以来第2次在湖南省境内发现,也是在湖南省发现的第2号该蛇标本,该标本现存于莽山自然博物馆。此方花丽斑蛇幼体体重12 g,体全长345 mm,尾长50 mm。头背有镶黑边的黄白色"Y"形斑;体背部紫红色, 相似文献

Snake envenoming is a major problem in Al-Jouf Province of Saudi Arabia where most of these envenoming are caused by Echis coloratus which is the highest risk to human and animals in this Province. Little, if any, has been carried out on the histological alterations and biochemical changes in the liver of sheep following snake envenomation. Healthy adult male Ovis orientalis sheep were subjected to E. coloratus envenomation in an attempt to evaluate the histological alterations and biochemical changes in the liver. E. coloratus venom elevated glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride and total bilirubin while cholesterol was reduced. The histological alterations were mainly pyknosis, karyorrhexis, cytoplasmic vacuolation, necrosis, fatty changes and hepatocytes atrophy. Sinusoidal dilatation, Kupffer cell activation, amyloidosis, portal vein thrombosis, partial glycogen depletion and hepatic architecture distortion were also detected. The findings revealed that E. coloratus venom produced biochemical changes and histological alterations in the liver of the envenomated sheep that might affect the functions of this organ severely. 相似文献

One of the relatively few vertebrate pheromones to be chemically identified, the female sex pheromone of the red-sided garter snake (Thamnophis sirtalis parietalis) is a series of saturated and monounsaturated methyl ketones contained within female skin lipids. During the breeding season, this pheromone is responsible for eliciting male courtship behaviors and males are able to utilize pheromonal variation to discriminate among females. While the pheromone system of the red-sided garter snake has been the subject of many studies, relatively little is known about the pheromone systems of other garter snakes. Through chemical analyses, we demonstrate that female skin lipids of the red-spotted garter snake (Thamnophis sirtalis concinnus), northwestern garter snake (Thamnophis ordinoides), and plains garter snake (Thamnophis radix) contain similar methyl ketones. The methyl ketone profiles of these snakes differ qualitatively from one another and from the methyl ketone profiles of red-sided garter snakes with differences particularly pronounced between sympatric species. Our results provide evidence that the use of methyl ketones in sexual signaling may be ubiquitous for Thamnophis species and suggest that these compounds could play a role in reproductive isolation between species in this genus. 相似文献
