Knowra Public aquarium Public aquarium A facility open to visitors that displays aquatic animals and plants in managed tanks or other aquatic habitats. Public aquariums may also conduct research, conservation, and education.
Aquarium filtration : The removal or conversion of particles and dissolved wastes from aquarium water. Mechanical, biological, and chemical filtration keep display water suitable for its inhabitants.
Aquarium-based conservation : Conservation work by aquariums, including habitat protection, species recovery, and public engagement. Some facilities support threatened species and ecosystems beyond their exhibit tanks.
Fishkeeping : The practice of keeping fish in constructed enclosures for observation, study, or enjoyment. Public aquariums expanded a much older practice of maintaining aquatic animals in captivity.
Oceanarium : A large aquarium focused primarily on marine animals and habitats, often including expansive ocean-themed displays. Oceanariums emphasize marine environments, while public aquarium describes the broader institution.
Aquarium nitrogen cycle : The microbial conversion of toxic ammonia into nitrite and then less toxic nitrate in aquatic systems. This process governs how tanks handle waste from fish and other animals.
Captive breeding : The reproduction of animals under human care to maintain populations or support conservation. Breeding programs can sustain vulnerable aquatic species and supply managed populations.
London Zoo : A zoological garden in Regent's Park, London, opened in 1828 for scientific study and public visitation. Its early fish house helped establish the aquarium as a public attraction.
Marine park : A public attraction that keeps and displays marine animals, often combining exhibits with performances or rides. Marine parks may prioritize entertainment formats that differ from aquarium-focused exhibits and education.
Aquarium chiller : A device that removes heat from aquarium water to maintain a desired temperature. Cold-water exhibits need refrigeration to reproduce temperatures their species require.
Coral propagation : The cultivation of corals through fragmentation, larval settlement, or other propagation methods. Reef exhibits and restoration programs use propagated corals to build living displays or support reefs.
