“Seaweed” is the common name for numerous species of marine algae
Algae are a diverse group of photosynthetic aquatic organisms
Including microscopic, free floating organisms (called “microalgae”) such as phytoplankton
And macroscopic “fixed” organisms (called “macroalgae”) such as bull kelp

There are currently 27 aquatic farms permitted to grow various species of seaweed in Alaska, with 12 farms permitted exclusively for kelp
But not all permitted farms are actively growing seaweed, yet
Most seaweed farming activity is concentrated around regional hubs (such as Kodiak-Sun’aq and Ketchikan-Kichx̱áan) where seed suppliers and processors are established
With other hubs emerging near Cordova-Arwartuliq and Homer/Kachemak Bay-Qackimak.

Most growers are currently harvesting and selling raw, unprocessed kelp to for-profit processing companies
These companies handle cleaning, sorting, processing, and the manufacturing of value-added products such as blanched kelp noodles, kelp pasta, salsas, and spice mixes
Some small-scale independent growers may be developing “cottage industry” products, which also require direct marketing to consumers

It varies dramatically based on who you sell to, how, and where!
● Direct Market / Cottage Industry ○ Low Volume: 10s of lbs ○ High Price Point: $10-20+/lb
● Food Ingredient Wholesale ○ High Volume: 100s - 10000s of lbs ○ Low to Mid-Price Point: $0.45-8/lb
● Non-Food Use ○ High Volume: 1000s - 10000s of lbs ○ Low Price Point: < $1/lb

It can take up to two years to secure a lease and permit to operate
The Joint Application period for a DNR lease and ADF&G aquatic farm permit is open January 1 - April 30, annually
If you do not already have access to a site, good first steps include thinking about your business goals and assessing potential sites that would be feasible and profitable for you to farm Photo Credit: Noyo Center (2020) The 50:50 rule (50 individuals from within 50km of your farm site)
It costs money Kelp Farming Lease and Permit Costs
The cost of your aquatic farm lease and the permitting process depends upon the size of your lease and operation. Regardless of the size, fees may include:
● Cost of Alaska business license (usually $50, but currently free due to COVID-19) ● ADNR lease application fee, variable: ○ $600 if less than 1 acre ○ $1200 if 1-3 acres ○ $2000 if over 3 acres ● Aquatic farm permit application filing fee ($100 for an individual; $200 for a company) ● Annual lease fee ($450 for first acre plus $125/acre for each additional acre) ● Liability insurance and workers compensation, as applicable (variable) ● ADNR minimum bond ($2500)
