The Complete Guide to Aquariums
The word aquarium originates from the ancient Latin language, aqua meaning water and the suffix rium meaning place or building. Aquariums are beautiful and look good anywhere! Home aquariums are becoming more and more popular, it is a hobby that many people are flocking too and fish shops are on the rise. Fish are generally easy to keep although do they need quite a bit of attention. Puppies and kittens were the typical pet but now fish are becoming more and more frequent in house holds. In recent years fish shops have noticed a great increase in the rise of people wanting to purchase aquariums and fish, the boom has been great for local shops as the fish industry hasnt been such a great industry before now.
Rotifers in the wild have little significance to humans. They may have some economic significance, however, because many species are cultured as a food source for aquariums and cultured filter-feeding invertebrates and fish fry. They also may be used as biological pollution indicators.
The seasonal fishes lay their eggs in the substrate. Typically, a male defends a territory while mostly hovering over and close to the substrate. A receptive female approaches, angling with her head toward the substrate the male draws near, sometimes wrapping his anal and dorsal fins around the usually smaller female. The pair dives into the substrate, sometimes disappearing from sight. One or more eggs are released by the female and fertilized by the male. After a characteristic rolling motion designed to bury the eggs, the male and female emerge from the substrate. The eggs enter a resting state. The water in these habitats eventually evaporates, and the adults die or, more likely, are eaten by birds before the water is completely gone. Some of the eggs embryonate and hatch during the next rainy season. Even though the next rainy season may be months or, in a drought, years away, in a home aquarium these eggs may hatch after as little as two to three months of storage in damp peat...
Mantis shrimps are capable of some of the fastest movements in living nature. A stomatopod strike at a prey animal, including the unfolding motion, can pass in 2 milliseconds. The strike of a praying mantis takes 100 milliseconds, the length of time of one human eye blink. Smashers add enormous force to their strike speed. Two of the larger smasher species, Hemisquilla ensigera and Odontodactylus scyllarus, pack a punch nearly equal to the impact of a .22 caliber bullet, powerful enough to break open the double-layered safety glass of public aquariums, which in fact they have done.
Tropical plants should be hauled out of the pond and tossed onto the compost pile. Or if you want to overwinter them indoors, get the details from wherever you bought the plants or try to find a more experienced water gardener to help you. Some tropicals can stay in heated aquariums you can strip others of all growth and store their little tubers or rhizomes in damp sand.
A large amount of animal health data is collected, but this is generally to satisfy specific purposes, such as determining the prevalence of a disease within a target species. Organizations that use animal health data include farming enterprises, processors (such as abattoirs), farming service providers (such as veterinarians), pharmaceutical companies, and state and federal departments of agriculture. Organizations that use domestic animal health data include individual veterinary hospitals, veterinary wholesalers, and pharmaceutical companies. Personnel working in resource management, wildlife and fisheries, zoos, aquariums, and agriculture and human health have call to use wildlife data. The USDA collects information on animal health when it is a threat to agriculture. The Department of Health will collect animal health data when it is of significance to human health (e.g., salmonella, WNV vector data).
The vast majority of large- and medium-sized zoos and animal parks participate in using the International Species Identification System (ISIS), which is a standardized way of classifying and inventorying animal collections in zoos, parks, and aquariums. ISIS members include more than 450 such facilities, half of which are within the United States. ISIS developed a DOS-based program for animal cataloguing and inventory management called ARKS, which has an EVR extension called MedArks. Currently about 90 of ISIS member facilities use MedArks as their EVR, and in contrast to the situation often encountered in POC-equipped human medical facilities, the zoo or park will use MedArks to record the care of its entire animal population. MedArks is designed around a DOS-based, SQL-compliant Foxpro database. MedArks is designed to allow one institutional veterinary center to transmit its records to any other MedArks-equipped facility, as well as the ISIS central database, by e-mail or by mailing...
