绝大多数海水观赏鱼是生活在热带海区的珊瑚礁丛中，因而也称珊瑚礁鱼类。这些鱼类色彩斑斓，形态各异，具有很高的观赏价值。只是饲养海水观赏鱼的难度较高，一般较难在水族箱中长期饲养。在水族箱中，海水的盐度、硬度、酸碱度、氨筑等理化因子波动大，不可能完全人为调控。因此，水质很难适应珊瑚礁鱼类的生活要求，常常导致鱼类死亡。为解决水质问题，水处理设备必不可少。通常使用的水处理设备有砂床过滤、泡沫分离器、生物球、活性碳、紫外杀菌仪或臭氧杀菌仪等。海水有天然海水与人工配制海水之分，前者更适合于珊瑚礁鱼类的要求，但… 相似文献

The Introduced Fish Problem and the Aquarium Fish Industry 总被引：2，自引：0，他引：2

Of the 46 species of foreign fishes known to be established as reproducing populations in open waters of the contiguous United States, approximately 65% are known or presumed to have originated from the aquarium fish trade. Many escaped or were released from aquarium fish culture facilities and some were introduced by aquarists. More than 50 additional, non-established fishes, mostly aquarium species, have been collected in the wild. These introductions, with established populations, have not been restricted to the so-called Sun Belt states, but have occurred throughout the U.S.
Because many introductions have resulted in serious negative impcts to native fishes, and most have the potential to do so, it is imperative that the aquarium fish industry and trade take measures to curtail such releases. The means of accomplishing this goal are relatively inexpensive. Industry must assist in public education to reduce introductions by aquarists. 相似文献

Ornamental fishes endemic to Hawaii's reefs are a valued resource and a staple of the marine aquarium trade, worldwide. At present, the market for Hawaiian ornamental reef fish is supplied entirely by the export of wild-captured animals, but the long-term sustainability of this practice is debatable. The success of breeders of ornamental fishes elsewhere, and concerns about overexploitation of wild fishes have stimulated interest in the development of an industry based on the captive propagation and rearing of Hawaiian ornamental fishes. Initial attempts to spawn and rear the larvae of various marine ornamental fishes in Hawaii were carried out in the early 1970s. The results of these culture efforts, conducted primarily at the Oceanic Institute and the University of Hawaii's Hawaii Institute of Marine Biology on Oahu, have varied in success. For the most part, these results have appeared previously only in dissertations or in reports distributed locally. Technological improvements in marine aquarium husbandry and in the culture of edible marine fishes have both benefited practitioners of ornamental reef fish culture, and promise to do so in the future. Our objective in this paper is to review the progress that has been made in the captive cultivation of ornamental marine fishes and to provide an overview of the status of the marine aquarium industry in Hawaii. 相似文献

A market survey and review of government statistics were carried out to establish imports and exports of marine ornamental fishes into and out of Hong Kong, and to examine the local trade in terms of volume, value and species composition. Official government import figures for marine aquarium fishes were available from 1984 to 1991 and from 1997 and 1998. When compared with net imports, export and re-export volumes over the 15-year period were small, indicating that most imports entered the local market, or were exported unrecorded. The market survey of marine aquarium shops in Hong Kong was carried out between August 1996 and January 1997. From this survey, an annual estimate of 957,563 coral reef fish was calculated for the local trade, valued at HK$57,453,780, with a mean retail price of HK$60 per fish. These figures account for an estimated 2–3% of the global value and volume of marine aquarium fish trade, according to 1992 figures and, compared with government figures, indicate that official declarations of imports are underreported by at least 2–3 fold. A total of 342 marine aquarium fish species, from 49 families, were recorded with about 60% belonging to the families Labridae, Chaetodontidae, Pomacanthidae and Pomacentridae. It was estimated that a large proportion of the trade was in juvenile fishes and almost all fish were less than 10cm in standard length. It was common to see fishes in poor condition, species hard to maintain in captivity, or those listed for conservation concern, on sale. There are no regulations for local traders of live marine fishes other than those relating to either protected species or animal welfare. Licensing of traders in marine fishes could be introduced under existing Hong Kong legislation if fishes were to be re-classified as animals. This is strongly recommended as a step towards regulating and managing the trade in Hong Kong. 相似文献

Concentrations of major seawater ions were monitored in six aquarium tanks at the New Jersey State Aquarium over a three-year
period. The ratios of these ions to chlorinity were compared to those in freshly prepared artificial seawater. The largest
aquarium tank (Ocean Tank) exhibits statistically significant (p<0.01) relative enrichment of potassium, calcium and strontium,
and relative depletion of magnesium and sulphate. The likely source of excess potassium is from potassium iodide added to
prevent goiter in sharks. Based on the excess potassium, a total amount of 650 μmol/kg iodide added over the years was calculated
for the Ocean Tank. The excess calcium observed in several tanks correlates with the presence of concrete or arbonaceous shells
in these tanks. In Ocean Tank, a calcium leaching rate of 6.7 kg/month was calculated. Continuous formation of white carbonaceous
precipitates serves as a sink for magnesium in Ocean Tank, and a magnesium removal rate of 5.1 kg/month was calculated. These
and other results show that concentrations of major ions in artificial seawater aquaria are affected by leaching, precipitation
and addition of food supplements, and these factors should be taken into account when preparing artificial seawater for aquarium
tanks with long water residence time.

The aquarium hobby is popular worldwide, but it has positives and negatives for freshwater fish conservation. The most damaging impacts of the aquarium trade on ecosystems are overharvesting and invasive species. Consequently, many conservationists and academics have the perception that aquarium hobbyists are generally harmful to species conservation. Without overlooking these major drawbacks of the aquarium hobby, we aim to establish common ground between hobbyists and conservationists by correcting some misconceptions and showing the benefits of serious aquarium hobbyists in the conservation of freshwater fishes and their habitats. Our overview illustrates that the aquarium hobby is not insensitive to the pernicious effects of this enduring hobby on natural systems and that serious aquarists and their associations can directly assist and fund scientific research, increase conservation awareness among the general public and even participate in ex situ and in situ conservation programmes for native fish species at national or international levels. Whilst the relationship between conservationists and the aquarium hobby has often been antagonistic in recent years, ultimately most biologists and aquarists share a love of the species they study or maintain, and this common interest could be the basis for a more positive and productive relationship. 相似文献

Fishes and aquaticenvironments are often overlooked in conservation and sustainabledevelopment projects in Amazonia, yet the diversity of fishes(> 3 000 species) and the socio-economic value of thefisheries and the aquatic habitats have a great importance forthe region. Fishes are not only the principal source of proteinfor local people (> 70 kg/capita), many are also traded asornamental fishes in a worldwide market. The middle Rio Negrobasin is the major fishing grounds for live ornamental aquariumfish. Nearly 20 million live fishes are exported from the regionannually, generating more than US$ 2 000 000 annually forthe local economy. The trade in ornamental fish now contributesover 60% of the income revenue in the municipality. The goal ofProject Piaba is to promote an economically viable fishery forlocal fishers, and an ecologically sustainable resource for agreen aquarium industry. To arrive at these goals first requiresan understanding of the ecosystems and sociocultural systems ofconcern. The Project Piaba team has made baseline studies on thediversity of fishes and habitats, and socio-economic processes ofthe ornamental fishery. Five principal project goals are:(1) To collect baseline data on the ecosystem, socio-economy and diversity of fishes, to analyze the impact of the ornamental fish trade on social and natural environments.(2) To diagnose diseases, to introduce fish care techniques, to improve the survival and quality of fishes and turtles, and eventually to establish quarantine protocols at each level of the trade.(3) To provide environmental education and socio-cultural history to local fishers, distributors and public, and to promote career development in aquarium science and conservation.(4) To create community based fishery management strategies which would include managed harvest levels, stock enhancement of fishes and turtles and the development of aquaculture.(5) To assist in the revision of policies by regulatory agencies in order to protect vulnerable species and enhance the economic viability of the region 相似文献

A low-temperature marineaquarium has been maintained at the British Antarctic Survey(BAS) headquarters in Cambridge for over 15 years. In 1988 acompletely new aquarium system was designed and construct ed toprovide a cold-water environment for holding a variety ofAntarctic fishes and invertebrates. The philosophy behind the newAntarctic aquarium is to provide a controlled environment in asystem that is simple to maintain. One of the most importantenvironmental conditions is the provision of a continuous low airtemperature and controlled sea water temperature, to facilitatethe transfer of specimens between holding and research facilitieswithout there being a significant difference between air andwater temperatures. In this way specimens are freed from thedangers of temperature stress. This paper describes how theseconditions have been established. It outlines the design,construction and operation of the BAS Marine Aquarium, one of theUK's most unusual marine researchfacilities. 相似文献
