Thorea hispida - red seaweed
Algae - from time immemorial, synthesizing organisms that maintain an independent or joint routine of existence. They demonstrate a mixed form of organisms that are assigned to various departments of plants and even to different empires of an integral world. According to the latest data on the Earth there are about 36–41 thousand species of algae.
The red alga Thorea hispida (Torea ciliate) was first found in the Danube in Serbia in the 19th century. Currently, it belongs to rare plants and is on the verge of extinction. In Russia, this algae is listed in the Red Book, only in rather rare places can it be found in the Moscow River in the city.
Thorea hispida is the rarest algae that adorns aquariums; it can also be found in freshwater rivers. It grows on stones and on branched parts of a tree in sunny places, at a water temperature of about 15C to 25C, at a pH of 8.1. You can meet the Thorea Hispida seaweed in various parts of the world, but its ecological conditions will be approximately the same everywhere.
To grow Thorea hispida in an aquarium, you need to provide her with excellent lighting and nutrients. It is also necessary to keep in mind that any algaecides will be deadly for this alga, as well as the addition of carbon dioxide (CO2) to the aquarium.
Thorea hispida - this alga is reasonably gorgeous. Red-brick color, it demonstrates terry long strings that reach a length of about two meters. Perfectly creates contrast in the aquarium with green aquatic plants.
Characteristics of Red Algae
Gametophyte tall from 9–16 to 110 cm long, branching repeatedly and abundantly. In water, the thallus is tinted in a brownish-green color scheme; when dried, it turns out to be crimson-violet. The main axis of the thallus is a bundle of densely intertwined, but not fused, strands. The ligament of the main plexuses is not more than 190 microns wide. The crustal layer is formed by tightly connected ordinary or highly branched plastic exchanges of threads. In the vital biocycle of Karpospores (spores formed from a fertilized egg in red algae), an ultramicroscopic uniaxial stage is formed - Chantransia. It grows on stones in flowing waters, even sometimes at a depth of up to 3-4 meters.
In vivo conservation guidelines
Preserving the purity of water bodies is an important condition for the survival of this species of algae. Finding new locations of the species, coordinating their protection through the organization of specially protected natural territories. It is advisable to prepare special proposals for the maintenance and conservation of the species in its habitats.
Thorea hispida loves clean, transparent ponds, but with nitrates above 9.5 mg / l and phosphates of 172 micrograms / l - therefore, the level is very similar to the conditions in ordinary aquariums. This algae loves running water and bright places. But categorically does not like chemical pollution.
At home, in care, this alga is not too complicated. The main thing is to understand and remember its basic conditions for harmonious growth and growth.
Due to the wide adaptability to all kinds of living conditions, algae spread throughout the planet. They represent the greatest importance in the equilibrium of organic matter in various aquatic and terrestrial ecosystems: from polar infinity to tropical terrain, from oceans to elevated mountains. The extraordinary variety of algae captures their huge expenditure, for all kinds of scientific developments and diagnostics of the state of ecosystems.
