How do you dispose of elodea?
Remove this plant from aquariums and garden ponds. Dispose of plant material by drying in the sun and burying fragments. Never dump or grow aquarium plants in waterways.
How do you control elodea?
Elodea can be removed by raking or seining it from the pond, but will re-establish from any remaining fragments and roots. Fertilization to produce a phytoplankton or algal “bloom” prevents the establishment of most bottom rooted aquatic weeds and produces a strong food chain to the pond fish.
Is elodea a plant or animal?
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell.
Does Elodea produce carbon dioxide?
Symbiosis. The relationship between snails and elodea is symbiotic in that the snail eats algae and produces carbon dioxide. The elodea takes in the carbon dioxide and, through photosynthesis, creates oxygen, which the snail and every living thing in the tank uses to breathe.
How big are the leaves on Elodea canadensis?
The middle and upper leaves, typically three per whorl, are elliptic, approximately 2-5 mm wide; leaves in the upper whorls grow closely together. Male flowers are pedunculate by the elongate, filiform base of the floral tube, not released from the plant at anthesis; sepals 3.5-5.0 mm long, petals 5 mm long.
Why are Elodea plants good for fish habitat?
Elodea is an excellent oxygen producer and frequently used by fish to protect fry. Dense populations of plants reduce the water temperature and oxygen concentrations when plants die in late summer. However, dense growth of this plant can create a nuisance, and its closed, compact structure is not ideal fish habitat.
When does an Elodea plant start to produce fruit?
Elodea has branched stems with oval-shaped leaves arranged in clusters of three or four around the stem. The fruit of the Elodea ripens below the surface. Elodea produces heavy buds in the Fall that drop to the bottom and then begin to grow in the Spring; relying little on seed production.
