INTRODUCTION


INTRODUCTION

 

Captive fish have been important to mankind since prehistoric times.  Ancient Egyptians were the first humans known to keep fish not only for food purposes but as a source of food and entertainment. As depicted in their hieroglyphics, Egyptians mostly worked withTilapiaspecies and Mormyrids. 

Goldfish have been selectively bred in China since at least the 10th century.  However, Goldfish were not introduced into Europe until the late 17th century (c. 1791). In 1853, the London Zoological Society established a public aquarium to display fish species. By 1864, public aquariums had been opened in Paris and Hamburg. The majority of the fish in these aquariums were species that were local and could be caught in nearby rivers and lakes. In 1869, the first "tropical" fish was imported from Asia, the Paradise Fish (Macropodus opercularis). From that point on, more and more "tropical" species were imported from far off lands. 

In the early days, tropical aquariums were heated by an open flame, a dangerous and inefficient means of warming an aquarium. Filters were large, noisy and expensive. Water chemistry was poorly understood and good water conditioners did not exist. Fish suffered dietary deficiencies from the poor variety of live and dried foods.  Only a small variety of species was available, of those, only a few were well documented. The aquariast was at a loss of finding reliable information regarding fish size, feeding, care, and social behavior. Almost all fish were wild-caught; and few were captive bred. During transport, mortality rates were high, further driving up the cost of the hobby.  As a result, tropical fish-keeping,as it was known, was a hobby was for the rich and scientifically inclined.  Today, aquarium technology has improved and fish keeping is much easier.   

Today, most aquarium fish are still bred in Asia, although substantial numbers are produced in Florida. These captive-bred species have several advantages over wild-caught fish in that they are available on a more regular basis, are less likely to harbor a wide range of parasites, are less expensive, and tend to be hardier. However, successive generations of captive inbred fish tend to have less color and smaller fins than wild fish except in the case of selective breeding.

Tropical fish-keeping is becoming more and more popular despite the advent of aquarium simulation programs on the computer where a person can keep a fish tank without ever getting their hands wet.  The reason for the increasing popularity of the hobby is due to environmental awareness, the great variety of species, and relative ease of care of fish. Fish are pets that do not require much care, and an aquarium can add to the decor of a room.  Fish-keeping is an enjoyable hobby that can bring relaxation and enlightenment for persons of every age and interest. 







Recent news

Wildlife in the tropics plummets by over 60 percent

(05/15/2012) In 48 years wildlife populations in the tropics, the region that holds the bulk of the world's biodiversity, have fallen by an alarming 61 percent, according to the most recent update to the Living Planet Index. Produced by the World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL), the index currently tracks almost 10,000 populations of 2,688 vertebrate species (including mammals, birds, reptiles, amphibians, and fish) in both the tropics and temperate regions.


Educating the next generation of conservation leaders in Colombia

(05/14/2012) Colombia's northern departments of Cordoba and Bolivar are home to an abundance of coral reefs, estuaries, mangroves forests, and forests. Rich in both marine and terrestrial wildlife, local communities depend on the sea and land for survival, yet these ecosystems are imperiled by booming populations, overexploitation, and unsustainable management. Since 2007, an innovative education program in the region, the Guardians of Nature, has worked to teach local children about the ecology of the region, hoping to instill a conservation ethic that will aid both the present and the future.


Manta rays tracked by satellite

(05/11/2012) Satellite tracking technology has revealed new insights into the behavior of manta rays, reports the Wildlife Conservation Society (WCS). The findings are published in this week's issue of the journal PLoS.


Featured video: the oceans and Rio+20

(05/10/2012) A new video by Pew Environment Group and the Zoological Society of London (ZSL) hopes to convince policy-makers attending the Rio+20 Summit on Sustainable Development this summer that urgent action is needed to save the ocean's from an environmental crisis.


Over 30 Yangtze porpoises found dead in China as population nears extinction

(05/01/2012) Six years after the Yangtze river dolphin (Lipotes vexillifer), or baiji, was declared "functionally extinct" by scientists, another marine mammal appears on the edge of extinction in China's hugely degraded Yangtze River. In less than two months, 32 Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis), a subspecies of the finless porpoise, have been dead found in Dongting and Poyang Lakes in the Yangtze, reports the World Wide Fund for Nature (WWF).


Carnage in Komodo: world-famous reef destroyed by poachers' bombs

(04/25/2012) Illegal fishermen have been utilizing homemade bombs to kill fish off the coast of Komodo Island, Indonesia, reports the Associated Press (AP); the bombs have not only injured fish populations in the protected area, but has also blasted biodiverse coral reefs popular with tourists. A scuba teacher told the AP that a section of Tatawa Besar coral reef, a popular diving spot, had been "blasted, ripped off, turned upside down."
