Field ID

When you’re collecting sorus tissue from wild kelp beds, it’s critical that you correctly identify the species of kelp you’re trying to cultivate. In areas where there are a broad range of kelp species that grow intermixed, this can be intimidating. At first glance, many kelp species look the same. The following sections offer some guidance for identifying commonly farmed species of kelp and their possible look-alike species. The defining characteristics of different kelp species can vary by area. You should consult a scientific guide for your region to double check the specifics before you begin collection.
