Further, in step 2, the domesticating method of stigma basket fish preferably first adopts purse seine or net cage to carry out the adaptability cultivation of a period of time in sea area, observes and screen during cultivation to fish.
Further, also comprise the situation according to filamentous algae density in water body, stigma basket fish larger for some individuals is shifted out the step of water body.
Preferably, described step stigma basket fish larger for some individuals being shifted out water body, adopts fishing rod or cage net to carry out catching stigma basket fish.
Adopt technique scheme, the method utilizing stigma basket fish to carry out coral reef ecologic system reparation of the present invention, adopt stigma basket fish to carry out ecology and carry out coral reef ecologic system reparation; The algae that stigma basket fish is used for ingesting in coral reef habitat can be utilized, to reduce competitor's quantity and the density of coral, reach the object promoting purification coral reef ecologic system fast and effectively.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
The present invention is by putting into the Coral Reef Region needing to carry out habitat rehabilitation by stigma basket fish, with algae in coral reef habitat and the chip of ingesting, assist coral to get rid of unnecessary competitor algae, and increase water transparency by chip of ingesting, thus carry out coral reef habitat rehabilitation.
Concrete steps comprise:
(1) individual choice of stigma basket fish
Coral is assisted to get rid of competition algae unnecessary in water body because the fingerling chosen need possess, and the ability of water transparency is increased by chip of ingesting, input target should be chosen from the fish being staple food with algae and chip, and this fingerling is warm water cay fingerling, is suitable for surviving in warm tropical forest insect reef sea area.In addition, the fingerling chosen also must meet: be not 1. food with coral polyp, do not compete in ingesting with coral; 2. can play a role in improving to habitat, Coral Reef Region, have good mutualism relation with coral; 3. be suitable for coral reef sea area throw in, survival rate higher and can coral reef sea area normal growth with breed.
Stigma basket fish is that a kind of happiness inhabits in cay and coral thicket, and be mainly the fingerling of food with the algae such as silkweed, brown alga be attached on reef and coral, sociability is comparatively obvious, adaptable to environment.Therefore, stigma basket fish can be utilized to the algae ingested in coral reef habitat, promote purification coral reef habitat.The whose body weight scope of stigma basket fish is between 40-80g, and preferred 50-60g, the stigma basket fish of length between 8-12cm is individual.
(2) the raising and train of stigma basket fish
Because stigma basket fish is a kind of common edible fishes, the basket fish being used in coral reef habitat rehabilitation needs heavy, that growth is rapid, tolerance is strong active healthy individuals, and need select according to the needs repaired.As carried out habitat rehabilitation in Sanya, Hainan coral reef sea area, selecting the colony in periphery sea area, Sanya, being conducive to adapting to local environmental condition, selection individuality is comparatively large simultaneously, decorative pattern is obvious, has the individuality of certain ornamental value.
In addition, as conditions permit, preferably the basket fish being used in coral reef habitat rehabilitation is raised and train, raised and train in repair in the small water of sea environment conditional likelihood, period, fish that is unhealthy to some, injured or inadaptable input requirement screened out, satisfactory fish can be invested in the sea area of reparation, and can first adopt purse seine or net cage to carry out the adaptability cultivation of a period of time in sea area, period observes fish and screens.
(3) the releasing of stigma basket fish
According to the density of coral reef in sea area and the density of thread algae, being invested in the sea area of reparation of satisfactory stigma basket fish in step 2, will be raised and train.Throw in density to be determined by the density of coral reef in sea area and the density of thread algae, and determine the results dynamics to basket fish according to filamentous algae residual density.For the basket fish of about 50g, filamentous algae coverage rate about 10%, coral reef coverage rate in the sea area of about 30%, to throw in density be every mu of water surface 20-30 tail is reference.
Generally speaking, stigma basket fish no longer shifts out water body after throwing in, if but filamentous algae density is low to moderate basket fish deprivation of food, part basket fish can be shifted out water body, as the density of basket fish need be reduced, select the larger fish of individual in population to shift out as far as possible, thus regulate basket fish density in sea area.Preferably adopting fishing rod or cage net to catch when gathering in the crops basket fish, being used for more easily regulating basket fish density.
