2. Fish kill - Wikipedia

   en.wikipedia.org/wiki/Fish_kill

   Many cold water fish that live in clean cold waters become stressed when oxygen concentrations fall below 8 mg/L while warm water fish generally need at least 5 ppm (5 mg/L) of dissolved oxygen. Fish can endure short periods of reduced oxygen. Depleted oxygen levels are the most common cause of fish kills.

3. Harmful algal bloom - Wikipedia

   en.wikipedia.org/wiki/Harmful_algal_bloom

   Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.

4. Pond loach - Wikipedia

   en.wikipedia.org/wiki/Pond_loach

   Pond loaches are bottom-dwelling omnivores, feeding mainly on algae or scavenging organic materials, and may also eat on tubifex worms and other small aquatic invertebrates. Pond loaches are very hardy fish that can live in poor-quality water, and can survive short periods of drought by producing a layer of moisture-trapping mucus to keep ...

5. Mosquitofish in Australia - Wikipedia

   en.wikipedia.org/wiki/Mosquitofish_in_Australia

   Gambusia holbrooki has been implicated in the decline of at least 9 fish and 10 native frog species. [7] By consuming algae-eating zooplankton, they increase the chances of algae blooms in the water, reducing the water quality. They are very aggressive, and tend to attack other fish and nip their fins, leading to infection or death. [8]

6. Predatory dinoflagellate - Wikipedia

   en.wikipedia.org/wiki/Predatory_dinoflagellate

   Top row: unaffected fish; bottom row: fish preyed upon by the carnivorous alga Pfiesteria shumwayae. Predatory dinoflagellates are predatory heterotrophic or mixotrophic alveolates that derive some or most of their nutrients from digesting other organisms. About one half of dinoflagellates lack photosynthetic pigments and specialize in ...

7. Mosquitofish - Wikipedia

   en.wikipedia.org/wiki/Mosquitofish

   They are found most abundantly in shallow water protected from larger fish. [11] Mosquitofish can survive relatively inhospitable environments, and are resilient to low oxygen concentrations, high salt concentrations (up to twice that of sea water), and temperatures up to 42 °C (108 °F) for short periods.
