Ciguatera fish poisoning (CFP), also known as ciguatera, is a foodborne illness caused by eating reef fish contaminated with ciguatoxins. [ 4 ] [ 2 ] Such individual fish are said to be ciguatoxic . Symptoms may include diarrhea , vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness , and weakness.
This toxin results in the fish developing bleeding lesions, and their skin flakes off in the water. The dinoflagellates then eat the blood and flakes of tissue while the affected fish die. [33] Fish kills by this dinoflagellate are common, and they may also have been responsible for kills in the past which were thought to have had other causes ...
The following is a list of aquarium diseases. Aquarium fish are often susceptible to numerous diseases, due to the artificially limited and concentrated environment. New fish can sometimes introduce diseases to aquaria, and these can be difficult to diagnose and treat. Most fish diseases are also aggravated when the fish is stressed.
Freeze-dried and frozen fish foods were primarily developed for tropical and marine fish and are useful in providing variety to the diet or specialist feeding needs of some species. [4] These include tubifex worms, mosquito larvae, bloodworms, water fleas (Daphnia and Cyclops spp.) along with brine shrimp (Artemia salina). [citation needed]
A fish with swim bladder disorder can float nose down tail up, or can float to the top or sink to the bottom of the aquarium. [2] Swim bladder disease is a very common illness within aquarium fish that results in the bladder not functioning properly causing the fish to swim upside down.
It can affect both freshwater and marine [1] fish. [2] [3] It appears as tiny black spots on the skin, fins, and flesh of the fish. The life cycle of the parasite typically involves a fish-eating bird, a snail and a fish. [4] The black spot larvae grow to sexual maturity in the infected bird's intestine. The adult worms pass eggs with the bird ...
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.
Subsequent cooking, smoking, or freezing does not eliminate the histamine. [2] Diagnosis is typically based on the symptoms and may be supported by a normal blood tryptase. [2] [1] If a number of people who eat the same fish develop symptoms, the diagnosis is more likely. [2] Prevention is by refrigerating or freezing fish right after it is ...
