Smiley, a professor at the Fish Tech Center
who works in collaboration with researchers at the Oceanic Institute in Hawaii and the University
of Idaho, said that often
60 to 65 percent of a fish, depending on the species, can be discarded as waste.

He said the
highest value of a seafood product comes if it can be marketed as human food.
But some parts of a fish aren't very appealing to consumers in the United States.
When this happens, Smiley said the next best thing is to study the products
usefulness in agriculture or aquaculture. Recently, Smiley worked in
collaboration with other researchers to determine the potential of fish testes
as an aquacultural feed ingredient in the rainbow trout industry.

Smiley said the high cost of
standard fish meal means that farmed trout are typically raised on less
expensive soy meal. He acknowledges that rainbow trout are carnivorous do not
normally eat soy beans, but rather small bugs or krill, but by adding the fish
testes meal to the soy meal the trout are getting necessary nutrients that the
soy alone cannot provide.

Smiley said the work that he
and his team of researchers does provides needed background information so that
seafood processors and feed companies can determine if the product from such
studies could be made marketable.

they are still refining this research and designing economic analyses of the
meal as a viable product. It isn't currently being made in Kodiak, but could
be, based on the research he has done.
