Revision questions and answers for week four's disease management module.

In this quick revision, the important thing to remember is that you are aiming to pick out the specific facts relevant to the question. The final test at the end of the diploma will not be the kind of test that requires hundreds of words — no part of it runs as an essay. Instead, it will be conducted in the form of multiple-choice answers to a series of questions.

The layout below is a selection of practice questions, each of which probe your knowledge on the module you have just covered. Though they’re not laid out as multiple-choice questions and answers, they are designed to stimulate your mind to re-explore some of the main areas you’ll be tested on.

1) Is a colour change and a fish’s refusal to feed a specific or non-specific sign of an illness?


2) Would a sudden drop in temperature cause acute or chronic stress in a fish?


3) ‘Yawning’ in fish is sometimes associated with which type of environmental disease?


4) What damage can CO2 dosing do to a fish’s kidney?


5) Which bacterial infection can become so bad that a fish’s organs are exposed?


6) What is the name for an illness that can transmit from fish to humans?


7) Which kind of pathogen hijacks and organism’s cells to produce more of itself?


8) At which stage of the life cycle is it possible to treat white spot parasites?


9) Which nutritional disease leads to kinked spines?


10) What’s the usual course of treatment for an intestinal blockage?






















1) Colour change and a fish’s refusal to feed are non-specific signs of illness.


2) A sudden drop in temperature would cause acute stress.


3) Yawning in fish is sometimes associated with nitrate poisoning, or generic poisoning.


4) CO2 dosing can cause calcification within a fish’s kidney.


5) Ulcers can occasionally become so bad that they expose a fish’s internal organs.


6) A disease that can transfer from fish to humans is a zoonotic illness.


7) A virus hijacks and organism’s cells to produce more of itself.


8) It is possible to treat whitespot at the theront, or free-swimming stage.


9) Vitamin deficiency will lead to kinked spines.


10) Feeding food with indigestible content, and using Epsom salts is a usual course of treatment for intestinal blockages.
