Genus - Moina

Moina

Small freshwater zooplankton now confirmed as distinguishable from the smaller unidentified daphniid population. Moina persist in the Freshwater Lake and appear more concentrated in sheltered Lakeshore vegetation.

Identity & Origin +

Common Name: Moina
Scientific Name: Genus - Moina
Realm: Freshwater
Biome: Freshwater Lake
Date First Introduced: May 01, 2026

Population Dynamics +

Current Estimated Population: Hundreds present in the Freshwater Lake, with higher concentrations observed in sheltered Lakeshore vegetation.
Population Status: Established
Carrying Capacity Status: Stable but constrained; population persists but has not expanded to the expected large open-water densities despite abundant suspended food.
Date Last Observed: May 21, 2026

Section Notes

On 2026-05-21, Moina were confidently distinguished from the newly observed smaller egg-bearing daphniid-like species. The Moina population appears stable and established, with hundreds in the Freshwater Lake but stronger concentrations in sheltered Lakeshore vegetation. They are commonly visible on glass in the morning, remain hidden during the day, and become more active at night. Some ecological factor appears to be limiting abundance despite available food.

Trophic Ecology +

Trophic Level: Primary Consumer
Feeding Niche / Method: Filter feeder / plankton grazer
Dietary Inputs: Suspended algae, phytoplankton, microbes, and fine organic particles

Section Notes

Trophic classification is Primary Consumer. Food-web role: Suspended-algae plankton grazer. Feeding method: Filter feeder / plankton grazer. Dietary inputs: Suspended algae, phytoplankton, microbes, and fine organic particles

Environmental Tolerances +

Life Cycle & Reproduction +

System Reproduction Status: Established/persistent; reproduction should not be inferred from the earlier tiny-daphniid correction alone.

Section Notes

Moina are now confirmed as a separate established population from the tiny egg-bearing daphniid-like species. Continue treating the 2026-05-01 tiny-individual observation as uncertain for Moina reproduction, while 2026-05-21 confirms Moina persistence and habitat preference.

Ecological Role & Symbiosis +

Ecological Role: Small freshwater zooplankton and potential prey source within the Freshwater Lake food web.
Microhabitat Preference: Sheltered habitats, especially dense Lakeshore vegetation. Present in Freshwater Lake open-water/glass zones, often visible shortly after lights turn on and more active at night; tends to remain hidden during the day.

Section Notes

Stable but limited plankton grazer and prey resource. Shelter preference suggests vegetation structure may mediate Moina persistence and predation exposure.

Freshwater

A wet edge habitat where water, roots, glass, mud, and plant cover let aquatic and terrestrial organisms overlap.

Freshwater

A still freshwater habitat where submerged plants, suspended algae, microcrustaceans, shrimp, snails, and crayfish are reorganizing after fish removal.
