These Fish Keep Shrimps as Pets to Help Them Farm Algae

Seeing domestication, people have achieved great things by turning wolves from agriculture and aquaculture. Such adoption is seen in non-human invertebrates such as ant and spider farmers that have pet frogs to keep parasites in the bay. Now, a new study published in the journal Nature Communications details an example of domestication in an inhumane mental vertebrate, specifically longfin damselfish (Stegastes diencaeus). These fish employ the planktonic massed shrimp (Mysidium integrum) to help inactivate the algae farms they feed.

The Longfin couple will spend their lives protecting a patch of algae from other marine animals for the sake of those who may try to eat it. They patrol and if there is no free real estate on which they can farm, they will suck on coral polyps until they die and the algae have their place. This is why they are considered a danger to death, and the more they cultivate, the bigger their garden will be, the more corals will spread in the process. Parrotfish is another species that feed on algae and will target Longfin farms, but despite the huge size difference between the two, the Longfin is so aggressive that it can keep parrotfish away.

this new study sought to establish why long-lived creatures, which usually protect their algae from all living things, would tolerate the onslaught of mysterious shrimp floating in their backyards. They first needed to establish that if the behavior was widespread and so they were swimming a series of 30-meter (98-foot) laps on a reef in Belize, they made notes of when they saw the mysterious shrimp and which species was nearby. Their results show that fish farmers have found far more mysids than any other species, such as longfins.

Then, to find out if this association had any choice made by accident or by shrimp, they collected some secrets and exposed them to water contaminated by various “odors”. Mysteries have revealed that they are attracted to the smell of selfless farming but indifferent to non-agricultural fish.

To determine why the mysteries would try unselfishly, they put a few shrimps in small, clean plastic bags and how they reacted inside and outside the longfins Farm. They found that the mussels inside the yeast benefited from the longfins because they would protect the shrimp from the fish that wanted to eat the mussels. These shrimps outside the farm were not protected and attempt to make multiple predictions by other fish ended.

The final piece of the puzzle was to make sure that the longfins were benefiting by keeping this shake of mystery on top of their farms. They suspected that since the shrimps were on top of the algae, their waste could act as a fertilizer, meaning the longfins would enjoy the bumper crop. Certainly, analysis with and outside of longfins Farms showed that mysids farms were more generous than outsiders.

“These different analyzes suggest raising long-term non-smoked spicy shrimps together,” the researchers wrote in part of The Conversation. “Long-lived comfort provides a safe haven and instead mysterious shrimps provide fertilizer to couples for the farm.

“This relationship is important because these phenomena occurred in the distant past when excellent research provided insights into the history of domestication among our ancestors. In the long run selflessness, we see as happening in the early stages of housing. This is interesting because it coincides with a series like our proposed series that leads us to domesticate species like chickens, cats, dogs, and pigs. “
