新加坡是一个小岛国,农业用地及用于养鱼的海域面积均很有限。但新加坡观赏鱼产业相当独特和成功,是世界第一观赏鱼出口国,向80多个国家出售超过1 000种鱼类,2016年的年收入达到4 300万美元。该产业的成功主要源于其在许可证颁发,生物安全控制,养殖,包装,运输和疾病控制等各方面所具有的独特特征。新加坡正在努力驯养和培育许多高价值的海洋物种和新的淡水物种,并开发新型的循环水养殖系统。上游研究侧重于开发和使用基因组工具来培育新品种并维持野外种类的遗传多样性。但由于养殖鱼类的空间有限,邻国竞争激烈,该行业面临诸多挑战,其市场份额正在减少。在这篇综述中,我们将总结新加坡观赏鱼产业的现状和发展,讨论其面临的挑战,并提出保持该产业领先地位的建议。 相似文献

新加坡热带观赏鱼的养殖颇为盛行,已成为该国养殖业的一大特点。然而50年代,观赏鱼养殖在新加坡只是一种副业,经过多年逐渐发展成为一种欣欣向荣的产业。新加坡培育的热带观赏鱼畅销世界各地,除本国生产的淡水观赏鱼外,还收购其他亚洲国家部分海水观赏鱼.再出口,成为世界各国观赏鱼的集散地, 相似文献

新加坡观赏鱼产业与新加坡水族游乐业 总被引:1,自引:0,他引:1
新加坡是一座美丽的花园城市,风景秀丽,在新加坡330多万人口的社会生活中,优美的观赏鱼十分有地位。随着观赏鱼产业的发展,新加坡从观赏鱼的生产、经销、贸易直到欣赏、消费、游乐,逐步形成一个观赏鱼产业链。正因为新加坡观赏鱼生产与消费,前后呼应,紧密结合,才使新加坡观赏鱼事业不断推进和繁荣。本文简单介绍新加坡观赏鱼产业与新加坡水族游乐业的组成和特点,供业内人士参考。 相似文献

<正>新加坡的观赏鱼饲养起步较晚,直到19世纪,其居民才从中国引进金鱼从事消遣性的家庭饲养,直至上世纪五十年代,新加坡专业饲养观赏鱼的人员也不超过10人。1976年新加坡观赏鱼的出口额仅为676万美元,进口额只有196.5万美元,2007年出口额即达到6607.9万美元,进口额2346.5万美元,出口增长了近10倍,进口增长了近12倍。 相似文献

新加坡观赏鱼养殖规范、信誉好、诚信度高,产品容易进入国际市场,每年大约出口观赏鱼5000万美元,约占世界出口总金额的25%~30%。全世界每年出口观赏鱼数量约10亿尾,新加坡约为3亿尾。新加坡出口观赏鱼的44%依靠当地渔场自产,还有56%则依靠进口再转出口,成为“全球观赏鱼中转贸易中心”。 相似文献

海水观赏鱼贸易是海洋水族馆贸易行业的重要部分,是一项价值十几亿美元的产业,每年交易量达数百万尾,且需求量逐年上升,但由于严重依赖野生资源捕捞而使该行业饱受争议。目前,90%~95%的海水观赏鱼由野生捕捞获得,在已知的数千种珊瑚礁鱼类中,有一半以上在缺乏或无监测情况下进行贸易,自然资源面临严重威胁。观赏性水产从业者和消费者有责任保护野生捕获物种的可持续发展,海水观赏鱼的养殖被认为是一种保护野生资源的有效手段,但仍有许多技术问题阻碍其发展。文章结合相关数据和文献,概述了国际海水观赏鱼产业现状及最新研究进展,讨论了海水观赏鱼产业中存在的问题,并提出了一些可行的解决方案,旨在为中国海水观赏鱼产业发展提供一定的借鉴和参考。 相似文献

The occurrence of Mycobacterium spp. in freshwater and marine ornamental fish was studied in Italy from June 2002 to May 2005. Two surveys were carried out, one of aquarium fish sent to the Laboratory for diagnosis, and the other of prevalence of infection by mycobacteria in ornamental fish imported into Italy. Bacterial isolation was carried out from the spleen, kidney and liver, and the isolates were subsequently identified by biochemical tests. In the first survey, 387 fish were examined and Mycobacterium spp. were isolated from 181 (46.8%) fish. In the second survey 127 batches of ornamental fish from different countries were examined. Mycobacterium spp. were isolated from 38 (29.9%) batches. The following species were found: M. fortuitum, M. peregrinum, M. chelonae, M. abscessus, M. marinum, M. gordonae, M. nonchromogenicum and M. interjectum. There was a high prevalence of infection independent of the presence of macroscopic lesions. Mycobacterium fortuitum and M. chelonae were more prevalent than M. marinum in the samples examined. 相似文献

Recent developments and improvements in ornamental fish packaging systems for air transport 总被引:3,自引:1,他引:3
Current ornamental fish packaging systems are characterized by very high fish loading densities and high metabolic wastes in the transport water after shipment. They focus mainly on management of the quality of transport water. Recent studies using the guppy as a model fish showed that post‐shipment mortality could be reduced through enhancement of the stress resistance of the fish, and hence emphases should also be placed on the preparation of the fish for transport and recovery of the fish after shipment. Farmers can contribute significantly by applying nutritional prophylaxis before harvesting. Exporters may use the salinity stress test to identify fish lots of good quality for transport, apply health prophylaxis to eradicate parasites and optimize other techniques such as starvation of the fish or addition of salt to the transport water to enhance the stress resistance of the fish. Importers may adopt proper acclimation procedure and allow fish to recover in low salinity water to reduce post‐shipment mortality. As the main bulk of post‐shipment mortality is stress‐mediated and occurs during the 1‐week recovery period, the industry should consider revising the basis of the current warranty system for their customers, from death on arrival to cumulative mortality at 7 days post shipment (or death after 7 days, DA7), in order to cut down fish losses after shipment. 相似文献

A survey was performed on ornamental fish imported into the EU to detect viral agents belonging to the genus Ranavirus. The objective was to gain knowledge of the potential for these systemic iridoviruses to gain entry into the EU via international trade in ornamental fish. A total of 208 pooled samples, representing 753 individual fish, were tested. The samples included 13 orders and 37 families, originating from different countries and continents. Tissues from fish that died during or just after transport were collected and examined by standard virological techniques in epithelioma papulosum cyprini cells, by transmission electron microscopy and by PCR for the detection of the major capsid protein and DNA polymerase gene sequences of ranaviruses. Virus was isolated from nine fish species but ranavirus was not identified in those samples. The results suggest that ranaviruses are not highly prevalent in ornamental fish imported into the EU. 相似文献

Megalocytiviruses have been associated globally with severe systemic disease and economic loss in farmed food fish and ornamental fish. The viruses have been spread internationally by translocation of live fish. In New Zealand, megalocytiviruses are regarded as exotic. A potential pathway for introduction has been identified, namely imported ornamental fish. In the present study, real‐time PCR assays were developed for detection of megalocytiviruses using a conserved major capsid protein gene. A SYBR green assay was developed to target all known megalocytiviruses. A second real‐time PCR assay using a molecular beacon was developed to specifically target gourami, Trichogaster trichopterus, iridovirus, a species of iridovirus previously linked to ornamental fish imports in Australia. The analytical sensitivity for the SYBR green and molecular beacon assays were 10 and 100 fg, respectively. The analytical specificity of the real‐time PCR assays determined using genomic DNA templates from three target viruses, 12 non‐target viruses and 25 aquatic bacterial species were 100%. The intra‐run and inter‐run coefficients of variation of both assays were <5%. The real‐time PCR assays developed in this study provide rapid, sensitive, and specific detection of megalocytiviruses and gourami iridovirus. 相似文献

The suitability of decapsulated cysts of the fairy shrimp, Streptocephalus dichotomus as a sole diet was evaluated for the ornamental angelfish Pterophylum scalare larvae. Brine shrimp, Artemia sp., and microworms, Panagrellus redivivus, were used as comparison foods. The results indicate an appreciable weight gain of 15.22±1.69 mg and a growth (length) of 0.876±0.03 cm in experimental fish fed decapsulated fairy shrimp cysts compared with the growth and weight of fish fed other foods. The influence of the experimental diets was further reflected in the composition of fatty acid and amino‐acid profiles of the experimental fish. Angelfish larvae readily consumed the decapsulated cysts and utilized them efficiently during the early days of exogenous feeding. 相似文献
