  2. Aquaculture - Wikipedia

    en.wikipedia.org/wiki/Aquaculture

    When properly formulated (and often mixed with fishmeal or oil), plant-based feeds can provide proper nutrition and similar growth rates in carnivorous farmed fish. [ 108 ] Another impact aquaculture production can have on wild fish is the risk of fish escaping from coastal pens, where they can interbreed with their wild counterparts, diluting ...

  3. List of freshwater aquarium plant species - Wikipedia

    en.wikipedia.org/wiki/List_of_freshwater...

    Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.

  4. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .

  5. Saltwater aquaponics - Wikipedia

    en.wikipedia.org/wiki/Saltwater_aquaponics

    Saltwater fish generally fetch a higher market price than freshwater fish which makes for an economic incentive over traditional aquaponics systems. [6] It was also found that half pearls could be grown in cultured giant abalone in 5 months after a pearl nucleus was inserted into them. The shells can also be used for mother of pearl work. [2]

  6. List of marine aquarium plant species - Wikipedia

    Also known as Maiden's hair plant, this popular, stringy algae is often mistaken for hair algae and enters the aquarium trade on live rock and coral. It is toxic, making it inedible and capable of effecting coral growth, though microinvertebrates enjoy living within the algae such as amphipods and copepods.

  7. Aquatic plant - Wikipedia

    en.wikipedia.org/wiki/Aquatic_plant

    Aquatic plants have adapted to live in either freshwater or saltwater. Aquatic vascular plants have originated on multiple occasions in different plant families; [5] [9] they can be ferns or angiosperms (including both monocots and dicots). The only angiosperms capable of growing completely submerged in seawater are the seagrasses. [10]

  8. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  9. Plant development - Wikipedia

    On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
