Kona Blue Water Farms Awarded NMFS Grant to Research Alternative Proteins in Marine Fish Diets

By-Products From Biofuels, Food and Fish Processing Could Improve Sustainability of Kona Kampachi® Diets

KONA, HI--(Marketwire - May 5, 2010) -  Kona Blue Water Farms, Inc. (www.kona-blue.com), the first integrated marine fish hatchery and open ocean mariculture operation in the United States, today announced that the company has been awarded a Saltonstall-Kennedy grant from the National Marine Fisheries Service (NMFS) for research into alternative protein sources to reduce the reliance on marine proteins in aquaculture feeds. 

The project will look at three novel, sustainable sources of protein as a substitute for fishmeal in the diets of Kona Kampachi®, a sashimi-grade, marine finfish grown in waters offshore of Hawaii. The three sources of protein to be studied include: microalgal by-products from biofuels production; a single cell protein made from food processing water; and, a Fish Protein Concentrate filtered from the wastewater of fish processing plants. 

For the study, Kona Blue will substitute these various protein sources at different ratios into the Kona Kampachi® diet, and compare growth rates, food conversion ratios and product quality to that of fish fed their standard commercial diet.

"This research addresses the fundamental challenge of developing marine fish diets that are both scalable, and sustainable," explained Neil Anthony Sims, co-founder for Kona Blue. "The study aligns closely with Kona Blue's commitment to continually strive to soften our footprint on the seas." 

"By using by-products from other processes, we can re-use resources, rather than deplete them," said Jennica Lowell, Research Manager for Kona Blue and Principal Investigator for the project. "Not only do we lessen our reliance on Peruvian anchovies as a source of protein for our fish, but we also find value in by-products or effluents from other food processing or fuel systems."

Monterey Bay Aquarium's Seafood Watch Program, and a number of other aquaculture standards, use protein conversion efficiency of marine fish as a key metric of sustainability.

"Kona Blue aspires to use sound science to develop innovative solutions to the problems facing the oceans," said Sims. "It is imperative that we find alternative means of supplying healthful seafood to meet growing global demand. Developing more sustainable marine fish diets would alleviate one of the remaining concerns for scale-up of open ocean mariculture."

The research work is projected to begin by July this year. Results from the study will be shared with academics, industry, and the environmental and conservation communities through conference presentations and peer-reviewed publications.

Kona Blue Water Farms' applied research also focuses on areas such as new designs for open ocean net pens, hatchery production of imperiled native Hawaiian fish species, and satellite tracking of ocean current eddies in the lee of the Big Island. These research projects are supported by NOAA, USDA, the National Science Foundation and private industry partners.

About Kona Blue Water Farms

Kona Blue Water Farms -- the first sustainable, integrated marine fish hatchery and open ocean mariculture operation in the United States -- is located in Kona, Hawaii. Kona Blue breeds Kona Kampachi®, a premium, versatile Hawaiian yellowtail endorsed by top chefs nationwide, in an on-shore hatchery, transferring fingerlings to submersible, offshore net-pens deep in the Pacific Ocean where they are grown to a harvest size of more than four pounds. The sashimi-grade fish have no detectable amounts of mercury and are grown with no additives, genetic engineering or hormones. Since 2005, the company has produced over 2.7 million pounds of Kona Kampachi®, striving to exemplify responsible open ocean mariculture, and dedicated to delivering delicious, sustainable, healthful seafood without any significant environmental impact. For more information, visit www.kona-blue.com
