Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green. Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae. In the temperate Mediterranean sea, coralline algae are the main builders of a typical algal reef, the Coralligène ("coralligenous"). Many are typically encrusting and rock-like, found in marine waters all over the world. Only one species lives in freshwater. Unattached specimens (maerl, rhodoliths) may form relatively smooth compact balls to warty or fruticose thalli.
A method for inducing coral planktonic larvae to improve their attachment ability
This invention discloses a method for inducing coral planktonic larvae to improve their attachment ability in the field of planktonic larvae induction technology, comprising the following steps: Step 1, cutting shell-like coral algae to a certain particle size to obtain shell-like coral algae particles, and then filling the shell-like coral algae particles into porous shell-like coral algae to obtain an induction culture substrate; Step 2, placing planktonic larvae on the induction culture substrate, then placing them in an induction culture container, and immersing them in seawater at a temperature of 27°C for 2-7 days; Step 3, keeping the seawater warm through the induction culture container, and after 2-7 days, raising the temperature of the seawater through the induction culture container to continue the induction culture. This invention improves the temperature and induction structure under the condition of utilizing existing induction substrates, thereby enhancing the attachment ability of planktonic larvae.
