Science tells us that domesticated livestock and fowl cannot begin to address our world’s near-term protein needs, and that farming fish is our best option. Getting more public support is critical to the success of aquaculture and our planet. 

Oysters provide important, natural filtration of water and are an important component of many healthy coastal ecosystems because their active filtering can help improve and maintain water quality. For many coastal communities, oysters are an important food resource and excellent sources of protein and amino acids, zinc, selenium, iron and B-vitamins. 

KnipBio, a Massachusetts-based biotechnology startup founded in 2013, is refining the manufacturing process for a promising aquaculture feed ingredient that may one day form the foundation of the food that farmed fish eat. 

Dado que la producción de proteínas terrestres está confinada por la tierra limitada y disponible, la acuacultura es la solución lógica a nuestras necesidades nutricionales. Podemos tomar esto seriamente o podemos dejar que nuestros nietos crezcan en un mundo preocupantemente similar al de sus antepasados. 

As terrestrial protein production is confined by limited available and suitable land, aquaculture is the logical solution to our nutritional needs. We can get serious about it or we can let our grandchildren grow up in a world eerily similar to that of their ancestors. 

Poor-quality ingredients can’t become good-quality ingredients. Quality protein is essential for the healthy growth of any omnivorous or carnivorous aquaculture species. Insect meals seem to fill this need, and their mass-scale production appears to be sustainable. 

Since camelina and flaxseed oils contain more omega-3 polyunsaturated fatty acids (PUFAs) than most plant oils, the authors investigated them as replacements for fish oil in diets for cod, salmon and trout. 

The authors conducted research to determine the optimum dietary protein levels and protein:energy ratios for different age groups of olive flounders. 

Chlorella and other species have potential as protein sources in aquafeeds. In trials with tilapia fry raised in a recirculating system, the fish received a fishmeal-based control diet or feeds with portions of the fishmeal replaced by Chlorella. 

Enzymes obtained from fish- and shellfish-processing wastes can be used in the making of a number of useful products. Lipase enzymes from fish can break down lipids, while amylases hydrolyze starch. 

Fish protein hydrolysates have been used in the food industry for the development of antioxidants, emulsifiers, flavoring agents, anti-bacterial agents and feed. As natural products, they have a growing acceptance, since natural products are preferred by some consumers over industrial products. 

After a decade of research, Korea has produced individual glass eels for Japanese eel aquaculture. Despite dependence upon the wild seed, Japanese eel aquaculture production has been growing significantly and comprises over 27 percent of Korea’s freshwater aquaculture. 

Fish protein hydrolysates are naturally rich in nutrients that can help support aquatic species’ immune defenses in resisting stressors. 

Meat recovered from seafood processing byproducts could be combined with nutraceutical ingredients to form customizable seafood items. 

Biofloc systems enable more intensive tilapia production. The fish adapt to the conditions within biofloc systems and grow well by utilizing the bioflocs as a feed source.
