Question 1 Report

Which of the following may cause disease in a fish pond?
Answer Details
Poor management practices may cause disease in a fish pond. This may include overfeeding, overcrowding, inadequate water quality monitoring, and poor sanitation practices. These factors can create an environment that is conducive to the growth and spread of harmful bacteria and parasites, which can cause disease in the fish. The other options listed may have different effects on a fish pond. Mixed stocking, for example, may help to control certain types of pests, while liming can help to adjust the pH levels in the water. Harvesting and fertilization are management practices that are necessary for the success of the fish farm, but they do not directly cause disease.
