New artificial shrimp are made from algae

A San Francisco based company called New Wave Foods, has just created artificial shrimp from algae products.

Shrimp is a favored seafood in the United States, however, shrimp harvesting and farming has many negative ecological consequences. Enters New Wave Foods: they have found a way to make synthetic shrimp from a variety of algal products. The shrimp texture comes from brown seaweed sugars, the flavor is from green algae oils, and the coloration is from red algae pigments.

Not only are these shrimp vegetarian, but also environmentally friendly.

Shrimp farming is getting a boost from incorporating seaweeds

Aquaculture is beginning to shift from mono-culture to integrated multi-trophic aquaculture (IMTA). While IMTA is still relativity a new idea in the industry, nature has been doing it all along and new studies keep illustrating the benefits.

A study just came out this month (Jan 2019) that looked into adding seaweed to shrimp farms. The study added three seaweeds: Gracilaria vermiculophylla, Ulva lactuca,  and Dictyota dichotoma to ponds growing white legged shrimp Litopenaeus vannamei. Then shrimp were infected with V. parahaemolyticus and WSSV to assess disease resistance and response.

The use of macroalgae in co-culture with L. vannamei provided a nutritional benefit that achieved higher growth than the control organisms, as well as improvements of the ammonium concentration and immune response after infection with V. parahaemolyticus and WSSV.

The study concluded that these additional benefits were diet related, however, live seaweeds would change the water properties and testing water quality would be an interesting next step.

This is a good example how a company could change from one product to two while enhancing yield and quality of the original product with very little additional cost.
