Preventive efforts include not eating reef fish, not eating high-risk fish such as barracuda, and not eating fish liver, roe, or fish heads. [2] Ciguatoxin has no taste or smell, and cannot be destroyed by conventional cooking. [2] There is no specific treatment for ciguatera fish poisoning once it occurs. [2]
A fish's hypoxia tolerance can be represented in different ways. A commonly used representation is the critical O 2 tension (P crit), which is the lowest water O 2 tension (P O 2) at which a fish can maintain a stable O 2 consumption rate (M O 2). [2] A fish with a lower P crit is therefore thought to be more hypoxia-tolerant than a fish with a ...
Some fish never adapt to aquarium life, refusing to eat anything but live amphipods and copepods (as in the wild); though individuals that do acclimatize to aquarium food are considered to be quite hardy and highly resistant to diseases such as marine ich. They are less likely to contract marine ich because they do not have the typical skin ...
Schematic representation of the flow of Nitrogen through a common aquarium. Ammonia poisoning is a common fish disease in new aquariums , especially when immediately stocked to full capacity. Ideally, the level of ammonia (NH 3 ) and ammonium compounds (i.e. those containing NH 4 + ) in fish tanks should be zero.
Fish food should ideally provide the fish with fat (for energy) and amino acids (building blocks of proteins) and the fish food (whether flake or pellet) must be speedily digested in order to prevent buildup of intestinal gas, kidney failure and infections (such as swim bladder problems and dropsy) and to avoid aquarium pollution due to ...
Velvet disease (also called gold-dust, rust and coral disease) is a fish disease caused by dinoflagellate parasites of the genera Amyloodinium in marine fish, and Oodinium in freshwater fish. The disease gives infected organisms a dusty, brownish-gold color. The disease occurs most commonly in tropical fish, and to a lesser extent, marine ...
The fish, and especially its viscera, have been assessed as potentially unsafe by a study conducted on Mediterranean specimens. [20] Saupes are not toxic all year round but only during certain periods, which raises suspicion of the role of algae toxins or phytoplankton ingested by fish, and swarming at certain periods, which renders it ...
Lastly, scientists stress the importance of developing long-term solutions to mercury contamination because, currently, the advice to avoid consuming high amounts of fish prevents people from getting vital nutrients, and is impractical in places where fish is the main source of food. [26]
