If you see something on your kelp that isn’t biofouling, but still doesn’t look right, consider reporting it to My Seaweed Looks Weird. This project aims “To accelerate the description of algal diseases worldwide, by screening samples submitted by scientists, seaweed professionals or members of the public.” You can also always ask other farmers in the Farm Operations topic in the Community.

Biofouling
The last, and arguably most important thing you’ll want to monitor throughout the growing season is the biofouling of your kelp blades. Biofouling refers to the growth of unwanted marine organisms on your gear, or your kelp blades themselves. Fouling typically sets in during the spring months when the light returns, the water starts to warm, and more organisms are competing for nutrients.
To a certain extent, biofouling can be trimmed from your blades, which will remedy the situation temporarily. But once you see your kelp starting to foul, it’s a strong indication that you should harvest soon, as things will rapidly start to get worse.
Read more about common types of biofouling and optimizing the time of harvest in the next course on Harvest.
