1 Gill flukes are âegg layersâ. 2  Depending on the temperature of the water the eggs can hatch from 4 to 30 days. 3  No treatment will terminate gill flukes in the âegg stageâ. 4  For this reason treatments must be done over a period of time and that time depends on the temperature of the water. Dactylogyrus (Dacs): are called gill flukes, however, gill flukes are also found on the body. 2  Gill flukes are âegg layersâ. 3  Depending on the temperature of the water the eggs can hatch from 4 to 30 days. 4  No treatment will terminate gill flukes in the âegg stageâ.
Incorporating organic matter into soil can have several impacts because it disturbs the physical, chemical and biological balances in the soil. It can: 1  change the amount of nitrogen that is available to plants. 2  change the amount of other nutrients available. 3  change the way the soil sticks together (soil aggregation).
Even minor pH changes can have long-term effects. A slight change in the pH of water can increase the solubility of phosphorus and other nutrients â making them more accessible for plant growth Â¹â°. In an oligotrophic lake, or a lake low in plant nutrients and high in dissolved oxygen levels, this can cause a chain reaction.
