Geoducks and Geoduck Seed




emerald sea farms

Quick Facts
Clinoardium nutalli “Heart Clam” or “Basket Cockle”.

They are an indigenous bi-valve filter feeder taking in the nutrient rich waters of British Columbia filtering the plankton that naturally occurs and expelling filtered water. 

Over the past 100 years this inter-tidal population of this species have dwindled due to over harvest.

Historically, the cockle is an important food source for First Nations tribes.

Common bi-product of the Geoduck Aquaculture systems.
Excellent source of vitamin B12, Iron and protein.

Sea Cucumbers - Quick Facts

Sea Cucumber (Parastichopus californicus) “Giant Red Sea Cucumber”, “California Sea Cucumber”, “Hai shen”, “beche-de-mer”.

The main market for sea cucumber products is China and Japan.

They are a delicacy and are said to have great health benefits. 

In traditional Chinese medicine, sea cucumbers are considered a health panacea and are used to treat kidney disorders, constipation and reproductive problems, including impotence.


Our Geoducks

In an environmentally safe and sustainable manner we grow a high value, high protein product.  

Quick Facts
The geoduck clam is the largest burrowing clam in the world.

They are bi-valve filter feeders taking in the nutrient rich waters of British Columbia filtering the plankton that naturally occurs, and expelling filtered water.

They live up to 180 years and range from the intertidal zone to a depth of 300 feet.

North America currently exports over 100 million dollars worth of geoducks to China every year and the demand is increasing.

We have been supplying geoducks to China for over 40 years and for the past 20 years we have been shipping the clams live to seafood markets.

The main market for geoducks is Hong Kong and China.

Growth Rates:
Our company is committed to a low density seeding. Using this model we believe we can grow geoducks to 1.5 pounds in 7 years and to 2 lbs in ten years.

Initially we intend to begin harvesting once the geoducks reach the acceptable market size of 1.5 pounds.

Mortality Rate:
Survival depends to a large extent on how healthy the seed is and what size it is when it comes from the hatchery. Our target survival rate is a consistent 60-70% survival of seed to harvest.

We believe we can attain this as a direct result of our work in reducing transport, handling trauma, as well as, recognizing and purchasing healthy seed from the hatchery.

Sea Cucumbers
are found from the low intertidal zone to a depth of 250 m. They are most abundant in areas with moderate current with cobbles, boulders or bedrock.

A scavenger that feeds on plankton and other organic matter. They feed by sifting through sediments with their tentacles, or using their tentacles to catch food flowing by.

Sea cucumbers are split and dried and are highly valued in Asian cooking.

Growth Rates
Sea cucumbers can live to be about 8 years old and grow to a length of 50 cm.

Sexual maturity is not reached until the sea cucumber is 5-6 years old.

Mortality Rates
The survival rate estimation is typically between 30 and 50 %.


Emerald Sea Farms have completed a market assessment that identifies the opportunity within the market. 

Scientific testing is being conducted and includes: density and transport research, sub tidal grow out methodologies for commercial scale cockle production. 

Harvest of the cockle is considered a new fishery and is under scientific review by DFO (Department of Fisheries and Oceans) and our application for tenure is currently in process for the commercialization of sub-tidal cockle aquaculture.

Growth Rates
High growth rates of 1-2 years.
High body meat to weight ratio.

Average meat recovery is 35.3%.

Mortality Rates
High survival rates are attributed to the new predator protection offered by our company. 

Nature’s design of the cockles shell adds an extra predation defense and maximize survival rates during seed transport and out planting.
