Although relatively inconspicuous, they have a major importance in the freshwater environment, both in terms of fundamental ecology and in relation to human use of natural resources (Bellinger and Sigee, 2010).
Phytoplanktons are a key food item for aquaculture because this industry utilizes phytoplankton for the feeding of the animals being farmed. In mariculture, the phytoplankton is naturally occurring and is introduced into enclosures with the normal circulation of seawater. In aquaculture, the plankton can be either be collected from a body of water or cultured, through the former method is seldom used. Phytoplankton is used as a food stock for the production of rotifers, which are in turn used to feed other organisms. Phytoplankton is also used to feed many varieties of molluscs including pearl oysters, and giant clams (Conte and Cubbage, 2001).
Phytoplankton population in a pond is usually comprised of numerous species of microscopic plants that live in horizontal band or zone near the water surface. The densest population is usually located in a horizontal band extending from about two to three inches below the surface to a depth of 18 to 20 inches. The depth of the band depends on numerous factors including pond turbidity, light penetration and available plant nutrients (Conte and Cubbage, 2001).
The clarity of a pond depends on the presence or absence of suspended materials such as microscopic clay particles and phytoplankton. In the absence of this a pond will appear almost crystal clear. When the algal species in the phytoplankton community reproduce, the phytoplankton will reach a density that can be characterized as a slight cloudiness or turbidity in the water. What is being observed is not the individual algal cells, but light reflecting off millions of microscopic, single- and multiple celled microscopic plants when the phytoplankton can be observed it is called an algal loom often, the phytoplankton population can become so dense that it will produce a deep opaque color at the pond surface (Conte and Cubbage, 2001).
The pond is an ecosystem that supports and protects the phytoplankton, with a large diversity of plants and plants belonging to the species that live near the pond, a wide range of living aquatic creatures, some of which will thrive in the pond. There is a limited number of living plants for many of these species who live in the pond and they also include many insects that also reside in the freshwater or sandy ecosystems.
The pond can be used for growing and drinking and for other recreational purposes.
Flowers
Fruit-bearing plants can also grow on the pond. These varieties can be found in a variety of ways on the floor of the pond with the leaves growing on a surface or as a hollowed out plant. These fruit-bearing trees can be found in almost any part of the lake. Flowers are mostly flower-bearing species that use the water as a food source for their roots. Generally, there are no more than 3 different types of flowers, with various leaf types that are grown in different parts of the pond. Flowers can also be cultivated like a crop. Fresh vegetables that have been washed down with water to release their roots into the pond can be used to produce their seeds or plant a seedling on the ponds.
Other Uses for Pond Aquarium Plants
The pond can be used for swimming, bathing, and fishing, although it does not provide many recreational or educational purposes because the creatures living around are quite large and hard. Additionally, in rare or rare instance, it could potentially be used for animal hunting and fishing as well as medicinal purposes. In rare cases it is not practical to use aquarium plants in the water for the purpose of fishing.
The pond can also allow for activities for fishing, fishing, geocaching, or other aquatic uses. The fish that live near the pond and are present in the lakes are known to be the large fishes that inhabit the pond.
The pond can be used as a breeding ground for many species of frogs. Fishes that dwell in it include the long-eared frogs, the giant bluefinch, the bluey-eyed yellowfin, the bluefish, the redheaded pinky, the short-sized trout, the blackbirds, the baleenbill, and the bluebirds. The water can flow through any of these species to allow for mating and for the purpose of fertilizing fish and other aquatic foods.
Other Uses of Aquarium Plants
The pond offers many other uses for the aquatic fishes. One of these is swimming in the pond. The water at the pond is also used for the aquarium use, as is the food which resides in it, such as the algae, fish eggs, molluscs, and freshwater fish such as the large blackfly. The animals and birds are
