Antibiotics for fish were replaced with algae. The immune response quadrupled

Building on previous research, scientists from the University of Australia Sunshine Coast recently...

experimented with adding 11 different types of powdered seaweed to a pelleted commercial diet of captive dusky girts (Siganus fuscescens).

Although three varieties of seaweed have been shown to be effective in boosting the immune response of animals, red algae Asparagopsis taxiformis (red asparagopsis),showed themselves to be better than their analogues.Even when the supplement made up only 3% of the fish feed, the immune response in the whitefish increased 4 times. This means that the algae made the fish four times more resistant to infection by pathogens.

In fact, seaweed has performed better than the four conventional immune-boosting foods currently used in aquaculture.

Interestingly, eating redasparagopsis also reduces the amount of methane released by cows when belching. Scientists are looking to conduct research to see if a seaweed feed additive will strengthen the immune systems of cattle and other farm animals.
