The Columbus Zoo and Aquarium has announced that four male weedy seadragons are carrying eggs—a first, according to the Zoo ...

Water quality in Flathead Lake and the rise and fall of different fish populations all point to the same culprit: introduction of the mysis shrimp in the 1980s. The significant ecological ...

Researchers at UC Davis last week released their annual “State of the Lake” report, detailing several significant changes in Tahoe’s water, including the plunging level of Mysis shrimp ...

To keep up with their nutritional needs, staff members soon switched to feeding them day-old, tiny mysis shrimp. They grew and grew, feeding on gradually larger mysis shrimp. The hatchlings ...

Zooplankton — which began to decline in the 1960s due to the growth of its primary predator, the Mysis shrimp — can help improve the lake’s clarity because they eat clouding particles.

Zooplankton population took a dive in the 1960s after Mysis shrimp, an invasive species, experienced a population surge as these shrimp are known to prey on zooplankton. According to the report ...

Since the 1960s, the zooplankton populations have decreased due to the growth of its primary predator, the Mysis shrimp. Zooplankton, especially the Daphnia and Bosmina species, have dropped to ...

That’s largely because, in late 2021, the lake’s population of Mysis shrimp “unexpectedly crashed,” according to the report from TERC. Those non-native creatures feed on two types of ...

The addition of mysis shrimp in the 1980s allowed lake trout to continuously outcompete the native bull trout, said Barry Hansen, a fisheries biologist with the Confederated Salish and Kootenai ...

"Daphnia and Bosmina largely disappeared from the lake after they were grazed down following the introduction of the Mysis shrimp in the 1960s," TERC Director Geoffrey Schladow said in a statement.
