Scallops

There are three large species of scallop that could be considered for culture in this area, the Japanese scallop, the rock scallop, and the weathervane scallop. Seed is only available for the Japanese scallop and there have been no trials where all three were cultured under the same conditions in northern waters. Thus, it is not known which species would really be the best for this area.

There is a large scallop aquaculture industry in Japan based on the Japanese scallop. However, the market for scallops is completely different in Japan. The Japanese eat all of the scallop meat, not just the small adductor muscle (which is all North Americans generally eat.) Because, we discard most of the meat, the recovery from scallops in thi country is only about 15%. At $14.00/kilogram wholesale price for adductor muscle meats, the price for the whole scallops would only be $2.10/kilogram (less the cost of processing). This price level is far too low to support any but the most rudimentary type of culture (e.g. bottom culture).

Japanese scallop that was cultured at Metlakatla. Note the very small size of the adductor muscle (labeled "M" and white in color) compared to the size of the gonad (labeled "G" and orange).

Some local scallops do land and grow on the culture gear. They could potentially be marketed in small quantities, perhaps as small whole scallops for inclusion in pasta dishes or as aquarium species.
