Zhan et al. (2020), using DNA barcoding, found 13 different operational taxonomic units of red algae growing within freshwater aquarium stores in Taiwan. [1] [a] Staghorn algae of the genus Compsopogon may exist on aquarium substrates and can be epiphytic on slow-growing plants. [2] It can form branched, whitish-green strands up to six inches ...
The term fish kill, known also as fish die-off, refers to a localized mass die-off of fish populations which may also be associated with more generalized mortality of aquatic life. [ 1 ] [ 2 ] The most common cause is reduced oxygen in the water, which in turn may be due to factors such as drought , harmful algal bloom , overpopulation , or a ...
These nutrients are normally a problem in aquariums and ponds because they cause nuisance algae to grow, and also because they cause sickness and/or other problems in aquarium fish, invertebrates and corals. [3] An algae scrubber allows algae to grow, but the algae grow inside the filter instead of in the aquarium or pond.
Destructive fishing practices are fishing practices which easily result in irreversible damage to habitats and the sustainability of the fishery ecosystems.Such damages can be caused by direct physical destruction of the underwater landform and vegetation, overfishing (especially of keystone species), indiscriminate killing/maiming of aquatic life, disruption of vital reproductive cycles, and ...
Aquariums are usually much more densely stocked with fish than the natural environment. This increases the amount of ammonia produced in the relatively small volume of the aquarium. The bacteria responsible for breaking down the ammonia by converting it to nitrite, Nitrosomonas , colonize the surface of any objects inside the aquarium.
Traditionally, when fish would exhibit dropsy, it was advised to “destroy” it. [2] However recently, it is recommended to “bathe” the fish in water that has aquarium or epsom salts dissolved in it, as the process of osmosis may help relieve pressure on the fish. Antibiotics may destroy or weaken the pathogen if it is bacterial so that ...
Traps at different levels in the marsh came into operation as the water level rose and fell. The traps at Budj Bim are seen as a form of Indigenous aquaculture dating back at least 6,600 years (older than the Pyramids of Giza [9]), with the Muldoon traps system seen as the world's oldest stone walled fish trap, and longest used fish trap in the ...
Myxobolus cerebralis triactinomyxon Henneguya zschokkei in salmon beard. Diseases can have a variety of causes, including bacterial infections from an external source such as Pseudomonas fluorescens (causing fin rot and fish dropsy), fungal infections (Saprolegnia), mould infections (Oomycete and Saprolegnia), parasitic disorders (Gyrodactylus salaris, Ichthyophthirius multifiliis ...
