Examples of FISH in the following topics:
-
- FISH can be used to detect RNA or DNA sequences of interest.
- Central to FISH are the use of probes.
- FISH is often used in clinical studies.
- Bacterial FISH probes are often primers for the 16s rRNA region.
- FISH is widely used in the field of microbial ecology, to identify microorganisms.
-
- Diphyllobothrium spp, the fish tapeworm, encompasses various species that can infect humans upon ingestion of under cooked or raw fish.
- For example, these tapeworms include those found on broad fish and salmon.
- The tapeworms found in fish exhibit the ability to also infect canines, felines, bears, and mussels.
- The life cycle for fish tapeworms includes movement through numerous hosts.
- The intermediate host is then ingested by a second intermediate host which includes the fish.
-
- For example, at interannual scales phytoplankton levels temporarily plummet during El Nino periods, influencing populations of zooplankton, fish, sea birds, and marine mammals.
- Freshly-hatched fish larvae are also plankton for a few days as long as they cannot swim against currents.
- Zooplankton are the initial prey item for almost all fish larvae as they switch from their yolk sacs to external feeding.
- Fish rely on the density and distribution of zooplankton to match that of new larvae, which can otherwise starve.
-
- They provide a crucial source of food to many large aquatic organisms, such as fish and whales.
- Some of the eggs and larvae of larger animals, such as fish, crustaceans, and annelids, are included here.

-
- The Cytophaga columnaris, also referred to as Flavobacterium columnare or Bacillus columnaris, are responsible for the columnaris disease in salmonid fish.
- Lastly, the species Cytophaga psychrophila, or Flavobacterium psychrophilum, is responsible for causing bacterial cold water disease (BCWD) in salmonid fish.
-
- In fact, the omega-3 acids in fish comes from the microalgae consumed at the bottom of the food pyramide and gradually passed up to the fish at the top.
-
- The flavbacterium are characterized by their ability to cause disease in freshwater fish such as salmon and rainbow trouts.
- Describe the role of Bacteroides in the normal flora of the human gastrointestinal tract and the role of Flavobacterium in causing disease in freshwater fish
-
- Legend: (1) Addition of food and nutrients, (2) Production of urea and ammonia by fish, (3) Ammonia is converted to nitrites by beneficial nitrosomonas bacteria, (4) Nitrites are converted to nitrates by beneficial nitrospira bacteria.
- Less toxic nitrates are removed by plants and periodic water changes. (5) Evaporation. (6) Light. (7) Soil. (8) O2 produced by plants. (9) CO2 produced by fish.
-
- An organism living in a pelagic habitat is said to be a pelagic organism, as in pelagic fish.
- Similarly, an organism living in a demersal habitat is said to be a demersal organism, as in demersal fish.
- Coral reefs also support a huge community of life, including the corals themselves, their symbiotic zooxanthellae, tropical fish, and many other organisms.
- Coral reefs provide marine habitats for tube sponges, which in turn become marine habitats for fishes.
-
- Foodborne disease can also be caused by a large variety of toxins that affect the environment such as pesticides or medicines in food and naturally toxic substances such as poisonous mushrooms or reef fish.
