What are Hokkaido Scallops?
First off, let us understand what Hokkaido Scallops are:
- Hokkaido Scallops are also known as Yesso Scallops.
- Hokkaido Scallops belong to a family of bivalve sea creatures. The scientific name for that family of bivalves is Pictinidae.
- As its name implies, Hokkaido Scallops are found off the coasts of Hokkaido Japan.
Are Hokkaido Scallops the same as Japanese Scallops?

- While Hokkaido Scallops are named due to where they are found in Japan, these scallops are also found in other parts of Japan. They include places such as the Tohoku region as well as Aomori Prefecture.
- As such, with regards to the question of whether Hokkaido Scallops are the same as Japanese Scallops, it can be said that they are the same, with a difference being the part of Japan that these Scallops come from.
Are Hokkaido Scallops exclusively found in Japan?
With regards to the question of whether or not Hokkaido Scallops are found exclusively in Japan, Hokkaido Scallops are also found near Russia. Furthermore, due to aquaculture, Hokkaido/Japanese Scallops are being cultivated in countries such as China, South Korea, Canada and Morocco.
What makes Hokkaido Scallops unique?
This then leads us to another question regarding what makes Hokkaido Scallops unique. According to some, it is said that Hokkaido Scallops are unique due to being especially fleshy. This attribute makes it a very renowned seafood product especially to seafood connoisseurs.
How are Hokkaido Scallops farmed?
We shall now discuss how Hokkaido Scallops are generally farmed:
- Wild Hokkaido Scallops are first collected as Spat(Scallop spawn) in the season of Spring (Between the months of March and June) with the help of Spat Collectors that are either monofilament Onion bags or cone shaped plates that are covered by nets.
- Generally, the Scallop Spat settles in these collectors about 30 to 40 days after spawning.
- The amount of Scallop Spat collected depends on the depth at which the Spat Collector is lowered at. Numbers can range from 300 to 1500 or more.
- The optimum temperature for the growth of the Scallop Spat is about 15 degrees Celsius/59 Fahrenheit.
- The Scallop Spat are then moved from the Spat Collectors after 3 months when their shells measure up to 10 millimetres in height to be kept in Pearl Net Nurseries.
- The young Scallops are then left to grow in two ways.
- The first way is through the use of suspended Pearl Nets called Suspension Culture.
- About 15 to 20 Scallops can be held in these suspended Pearl Nets (When the shells of these Scallops have grown to about 30 millimetres in height). When Scallop shells have grown to about 70 millimetres they will typically be kept in sets of up to 7 Scallops per Pearl Net.
- The Scallops will be considered ready for harvest when their shells have grown to 100 millimetres in height. It takes about 2 to 3 years from being taken from the Spat Collectors for Scallops to be grown to harvest size.
- At times they can be harvested earlier depending on factors such as temperature and their food supply.
- In Suspension Culture, Scallops are either hung horizontally in shallow water or vertically in slightly deeper water when they are approaching the harvest size of 100 millimetres.
- The other method that is used to farm Scallops is called Bottom Culture.
- In the case of Bottom Culture, the Scallops are kept in shallow water at varying depths depending on the height of the shells.
- Scallops nurtured through the Bottom Culture method take a year longer to be harvest ready than Scallops grown through Suspension Culture.
