Abstract
The invention relates to the aquaculture technique, which in detail is an ecological cultivating method for shallow sea fishes. In china northern fish cultivating areas, thermostable and large-scale algae such as asparagus are mixed cultivated to improve the culturing environment. The invention makes full use of asparagus to adsorb nitrogen and phosphorous to reduce water pollution; and at the same, the asparagus is an important economic algae, for which the economic benefit is increased. In conclusion, the invention possesses both ecological benefit and economic benefit, and is especially suitable for northern parts in China.
Description
Technical field
The present invention relates to aquaculture technology, specifically a kind of ecological cultivation method of fish and algae in shallow sea.
Background technology
At present, the shallow sea fish culture in net pen is in the northern China fast development.But mainly adopt the aquaculture model of single variety.Refuses such as ight soil that the residual bait that fish culture produces, fish are discharged and excreta often make the water nutrition salt content increase, and dissolved oxygen descends, and causes body eutrophication and substrate pollution.This ecological problem has seriously restricted the development of northern China fish-farming in shallow marine water industry.As seen, the shallow sea fish cultural technique that current people adopted is not considered the processing of pollutant and is utilized problem again.
The key of littoral fish culture industry sustainable development is with the breed control of waste that in breeding water body self-purification capacity scope wherein an approach is the utilization ecological principle, the developing ecology cultural technique.As raise together with large-scale economic algae in the fish culture sea area is exactly a potential ecologic breeding technology.The breed of northern China tangleweed has just begun from the mid-1970s, but what culture all is low temperature properties algae, as sea-tangle, undaria pinnitafida and laver etc.Yet, at the beginning of summer and autumn, but lack the breed of macro in temperature higher season.And the breeding environment environmental deterioration occurs in temperature higher season mostly.
Summary of the invention
The purpose of this invention is to provide a kind of solubilised state nutritive salt that can effectively utilize in the fish-farming in shallow marine water water body, and then alleviate the ecological cultivation method of shallow sea fish culture self-pollution.
Technical scheme of the present invention is: in the cage culture sea area, in the time of cultured fishes, also raise together with macro; It is characterized in that: described cage culture sea area is positioned at China the north (11～27 ℃ of cage culture sea area water temperatures), and described macro adopts resistant to elevated temperatures macro, to improve the fish culture environment; Described macro is an asparagus.
A kind of cultural method of asparagus is to culture 1 along net cage raft frame on every side every 1 meter to restrict, and takes to press from both sides seedling and hangs the method breed from above, and every rope clamp seedling partly is about 1 meter, 16～18 bunches of folder seedlings, every bunch of seedling is grown 13～15 centimetres, 0.1 kilogram of every rope clamp seedling, 1～2 meter of asparagus in the underwater, the tenesmus dropstone; The important cultural method that another kind is raised together with asparagus is a cultivated gardon asparagus near the shellfish culture raft frame the net cage, 0.8 meter of rope spacing; In China fish culture sea area, often also culture some filter-feeding bivalve shellfishs by the raft frame.
In the fish cage culture sea area of northern China routine, culture resistant to elevated temperatures macro---Gracilaria asparagus (Gracilaria lemaneiformis).Asparagus is extensively cultured in marine site, subtropics, China south, is a kind of important economic algae, has fast, high temperature resistant, the agar-agar content advantages of higher of growth.And as biofilter, the research in northern China fish culture sea area yet there are no report.
The invention has the beneficial effects as follows:
1. the ecological benefits characteristics that had.The present invention uses ecological principle, with macro---and the Gracilaria asparagus strengthens the self-purification capacity of breeding water body as biofilter.Be embodied in: 1. asparagus can effectively utilize a large amount of solubilised state NP nutriments that exist in the fish-farming in shallow marine water water body, help to realize culturing the recycling of " refuse ", and then alleviates environmental pollution; 2. fish besoin de respirer oxygen, and asparagus produces a large amount of oxygen by photosynthesis, so that useful to the fish and the environment of culturing; 3. asparagus utilizes the CO in the water body
2, thereby the pH value that can regulate seawater.In a word, the present invention has optimized the growing environment of fish, is a kind of effective ecologic breeding mode.
2. good in economic efficiency.Adopt the present invention can increase the breed variety kind, can not only cultured fishes, also increased the breed of asparagus, asparagus is China's a kind of important economic algae in south, edible, agar-agar content height is again the high-quality bait of abalone.Thereby cultivated gardon asparagus can be increased economic efficiency in the fish culture in net pen sea area.
3. adopt the present invention can utilize existing net cage and shellfish culture raft frame, without special installation, thereby cost is low, and the fish algae ecologic breeding that is in particular in the northern China coastal area provides a technology path.
Embodiment
Below in conjunction with embodiment the present invention is described in further detail.
Embodiment 1
Adopt the fish culture net cage that generally uses in the prior art, culture sea area (13.0～25.1 ℃ of sea area water temperatures) cultivated gardon asparagus naturally Qing Daogu Zhen Wan fish, cultural method is to culture 1 rope every 1 meter around net cage.Take to press from both sides seedling and hang the method breed from above, every rope clamp seedling partly is about 1 meter, 16～18 bunches of folder seedlings, and every bunch of seedling is grown 13～15 centimetres, 0.1 kilogram of every rope clamp seedling.Asparagus is dried up 1～2 meter, the tenesmus dropstone.In breeding process, asparagus can effectively utilize solubilised state NP nutriment in the breeding water body as macro, plays the effect that purifies water.Increase the mariculture product after asparagus grows up to, improved the culturing economic benefit.
Its result is: fish and asparagus growth are all fine.On May 15th, 1 to July 19, about 65 days, asparagus increased by 79 times, every rope output reaches 7.9 kilograms.The bright asparagus of every per mu yield surpasses 3000 kilograms, wherein contains 9.6 kilograms of N, contains 1.2 kilograms of P.
The present invention adopts the theory of " ecologic breeding " to plan the fish culture pattern, carries out " cleaner production ", can reduce the self-pollution of breed, optimizes breeding environment, thereby helps fundamentally to solve the pollution problem of shallow sea fish culture.Present embodiment is in the fish cage culture sea area of northern China routine, culture resistant to elevated temperatures macro---Gracilaria asparagus (Gracilaria lemaneiformis, the asparagus that present embodiment adopts is from ALONG COASTAL FUJIAN), utilize it to have characteristics such as growth is fast, high temperature resistant, agar-agar content height, use as biofilter, make fish ecologic breeding effect fine.
Embodiment 2
The difference of present embodiment and embodiment 1 is:
The asparagus of being adopted is from Guangdong Coastal (15.4～26.5 ℃ of sea area water temperatures).Asparagus is cultured near the shellfish culture raft frame the fish net cage, rope spacing 0.8m.
Its result is: fish and asparagus growth are all fine.On May 15th, 1 to July 19, about 65 days, asparagus increased by 76 times, every rope output reaches 7.6 kilograms.The bright asparagus of every per mu yield is same above 3000 kilograms.
Claims (2)
1. the ecological cultivation method of shallow sea fish in the cage culture sea area, in the time of cultured fishes, is also raised together with algae; It is characterized in that: 11～27 ℃ of described cage culture sea area water temperatures, described algae is adopted resistant to elevated temperatures macro, to improve the fish culture environment.
