The Detroit River now has one of the healthiest populations in the country, with more than 6,500 lake sturgeon, Chiotti said. There are now bans on commercial fishing and strict catch limits in place for recreational fishing for sturgeon, which are starting to show signs of recovery, Fischer said. Since then, other pressures, such as pollution, have decreased the life expectancy of the sturgeon, which makes the size of this particular fish even more impressive, Chiotti said. "About 120 years ago, there was a very strong commercial fishery for sturgeon across the U.S.," Justin Chiotti, a fish biologist at the AFWCO who was not involved in catching the sturgeon, told Live Science. However, one of the main factors was historic overfishing. There are a number of reasons for this, including toxic pollution in waterways and the construction of dams and flood-control measures that impact their ability to travel upstream to their spawning grounds. Lake sturgeon are currently listed as threatened in 19 of the 20 states they are found in, including Michigan, according to the USFWS. "They are a large, charismatic fish, and a lot of people enjoy seeing them and knowing they are out there," Fischer said. ![]() Lake sturgeon are also very popular among local residents of the Detroit River area.

Sturgeon are bottom-feeders and spend most of their time at the bottoms of rivers and lakes, where they feed on insects, worms, snails, crayfish and small fish. ![]() These characteristics, combined with their large size, give the fish their monstrous appearance but they are actually completely harmless to humans. These may be easy to locate, like Acorns, Coal, or White Algae, or they may be rarer, such as Dried. The fish will ask you to bring them a particular item or items. The sonar revealed a sturgeon roughly twice as long as anything seen that dayconfidently estimated at just over 14 feet from nose to tail tip. Quests will only spawn when a Fish Pond is at maximum capacity. Sturgeon look very similar to their prehistoric ancestors and have a distinct shark-like tail and rows of armored plates called “scutes” for protection. Every so often, the fish in your Fish Ponds will give you a quest, noted by an exclamation mark symbol over the pond. ![]() Males can live for 50 to 60 years, but the females are believed to have life spans that exceed 100 years, and as a result they can grow to be much larger, according to the USFWS. After informing of the sturgeon to Queen Elizabeth II, the fisherman, a man named Robert Davies, received notice that he could use the 264lb catch as he saw fit. Lake sturgeon ( Acipenser fulvescens) are found in freshwater systems across the U.S., from the Hudson Bay to the Mississippi River. The law of royal fish continues to excite some notice and occasional use, as evidenced when a fisherman caught and sold a sturgeon in Swansea Bay in 2004.
