Virus
Type of transmission where it is transmitted from parent to offspring
Vertical Transmission
Rod shape Bacteria
Bacilli/Bacillus
Fungi are heterotrophic organisms, which contain chlorophyll and are historically compared to plants. True or False?
Parasites that live within the host, such as internal organs
Endoparasites
Which of the Water Quality Parameters when extreme causes scale loss to fish and thinning.
Salinity
Spinning Tilapia Syndrome (ST)
He is the one to explain the relationship between an organism and a specific disease.
Robert Koch
This disease outbreak is caused together by rhabdovirus and the bacteria Aeromonas hydrophila and the fungus Aphanomyces invadans.
EUS / Epizootic Ulcerative Syndrome
Parasites life cycle where they utilize more than one host for the completion of their life cycle
Indirect Life Cycle
This is cause by drop in pH to the level that is not in the range of your species
Acidosis
This is caused by rhabdovirus where your shrimp develops an abnormally feed intake and rapid growth before having reduced feed consumption and cessation. You can see a yellow to brown coloration to it as well.
Yellow Head Virus (YHV)
This usually occurs during summer months which cause 50% mortality of higher. First signs shows anorexia and darkening of of fish. In hatcheries, the presence of red spots in tank is a sign if having this
Vibriosis
Fungi usually have this in their cell walls.
But some organisms that were once considered “lower fungi” actually have a different one.
Because of this difference, scientists realized they’re not true fungi. These “lower fungi” were reclassified into another group called Kingdom Stramenopila.
What does fungi and and lower fungi have in their cell wall that differentiates them?
True Fungi = chitin
lower fungi = cellulose
This is a type of Protozoan infestation where a spore-forming parasites produce spores that can survive in water and infect new hosts. They actually belong to the phylum Cnidaria.
Myxosporeans
Gas bubble Diseases is caused by supersaturation of gases mostly ......
Nitrogen
Give one disease caused by Iridovirus
Lymphocystis Disease
Grouper Iridovirus of Taiwan Disease
Sleepy Grouper Disease
Spinning Tilapia Syndrome
Give one causative agents of Vibriosis
Vibrio alginolyticus, V. anguillarum and V. vulnificus
Gills become pale with brownish areas due to hemorrhage and thrombosis, or grayish as a result of ischemia. Necrotic areas might slough-off at a later stage becoming a focus for saprolegnian infections.
Branchiomycosis (Gill Rot ot ot ot)
These parasites are endoparasitic tapeworms with a body that is ribbonlike, segmented or unsegmented and armed with hooks or suckers
Cestodes
You have a shrimp farm and during your pond preparation, you have applied to much lime causing your pond to have a high pH level. This is worsen as your pond has low salinity. What disease is most likely to have on your shrimp?
Red Disease
What is IHHNV? What causes it and its signs and symptoms?
Infectious Hypodermal and Hematopoietic Virus (IHHNV)Disease, Parvovirus, shrimp shows erratic swimming to surface and roll till ventral portion is up then sinks to bottom. Repeating the process until dies
This is an external disease with signs similar to those caused by other gram-negative bacterial pathogen of fish causing small hemorrhages in the skin around the mouth and opercula and along the ventral or abdominal surfaces. The body surface may ooze blood and slime in severe cases but there is no reddening of the fins and anus.
Pseudomonad Septicemia or
Red Spot Disease
There is a formation of white cottony growth on fish eggs and on affected tissues of fish. Gills, eyes and olfactory pits may become infected. The color of the mycelium may also vary from white to brownish, depending on the color of the particles, which get trapped on the mycelium.
Saprolegniosis (Saprolegniasis)
Give one causative agent for sea lice
Caligus epidemicus or Caligus patulus
What causes Muscle Necrosis in shrimp?
Muscle necrosis in shrimp is caused by temperature and salinity shock, low oxygen levels, overcrowding, rough handling and severe gill fouling
