Answers
One infected fish cannot disinfect the whole lake ,it can only infect it if it is a contagious infectious disease
Answer:
The zoonotic diseases associated with fish contact are primarily bacterial infections. These include Mycobacterium, Erysipelothrix, Campylobacter, Aeromonas, Vibrio, Edwardsiella, Escherichia, Salmonella, Klebsiella and Streptococcus iniae.
These are some of the most common signs of disease seen in pet fish:
- Appearing disoriented, such as swimming upside down.
- Leaving food uneaten.
- White spots on fins or body.
- Discolored gills.
- Trouble breathing such as gasping at surface of water.
- Bulging eyes (one or both)
- Mucus accumulation on the body.
Treatment: Firstly, test the water in your fish tank and carry out a partial water change. If the clamped fin is the result of an infection, a multipurpose antibiotic can be applied to the water, and adding one tablespoon of aquarium salt per gallon will also help.
Effective treatments include levamisole, metronidazole or praziquantel. Metronidazole and praziquantel are especially effective when used as food soaks. Antibiotics such and nitrofurazone or erythromycin may also help prevent secondary bacterial infections.
Salmon, in particular, should be bought previously frozen — salmon is anadromous, living in both salt and fresh water, and can pick up worms that other ocean fish don't; though curing can kill bacteria, only proper freezing can kill these parasites. Keep the fish refrigerated at all times, even after it is cured.
These parasites are usually killed by cooking the fish to a temperature of at least 145°F for fifteen seconds. The Food Code and the Texas Food Establishment Rules require that fish that are to be consumed raw or undercooked be frozen at a temperature and time guaranteed to kill parasites.
Anisakid roundworms are the most common parasite found in marine fishes. Other names for these threadlike nematodes are herring worms, cod worms and seal worms. Freshwater perch, trout, and salmon (that spend part of their life in freshwater), may carry the tapeworm larvae of Diphyllobothrium.
Fish that you should not eat:
- Wild Caviar. Why it's bad: Caviar from beluga and wild-caught sturgeon are susceptible to overfishing, but the species are also being threatened by an increase in dam building that pollutes the water in which they live. ...
- Red Snapper. ...
- Chilean sea bass. ...
- Orange roughy. ...
- American Eel. ...
- Imported King Crab. ...
- Atlantic Salmon.
