Below by drawings and Examples the present invention is at length explained.
Description of drawings
The structural representation of the special-purpose net cage of Fig. 1-the present invention;
The vertical view of the special-purpose net cage of Fig. 2-the present invention.
Its body embodiment
With reference to figure 1, Fig. 2, interior net cage 2 can make 4 * 4m specification, outer net cage 3 makes 5 * 5m specification, do the bottom of outer net cage 3 tapered, ight soil outlet 5 is left in the centre, ight soil outlet 5 belows are provided with a collecting dung mesh bag 6, inside and outside net cage is fixed on the net cage frame 1, net cage frame 1 around tie up again the system several cursory 4.Select the 750 cubes of conduct tests in suitable sea area breeding water body, 10 groups of above-mentioned compound special-purpose net cages of layout are put 100g marine fish 16000 tails in a suitable place to breed in interior net cage 2, put 5000 of 2-3cm abalones outside in the net cage 3 in a suitable place to breed, 10000 of 4-5cm stichopus japonicus, 10000 of 1-2cm sea urchins, 10000 of 1cm Patinopecten yessoensis.During the breed, inwardly throw in bait in the net cage 2, the data such as macro, routine observation, record growing state, change of water quality, survival rate of outwards throwing something and feeding in the net cage 3.
Find in the test, the assorted algae that adheres on the etting is by the sea urchin removing of looking for food, algae residue and the remaining bait major part that spills from interior net cage are by sea cucumber, abalone ingests, have only a spot of ight soil to be pooled in the collecting dung mesh bag by the ight soil outlet of outer net cage bottom, the seabed is polluted and is obviously alleviated, scallop can be filtered the plankton in the drinking water, make the interior water quality of net cage pure and fresh, reduced and taken pathogene organic granular density, reduced the generation of disease, add that moving about of fish promotes the exchange of water body in the net cage, improved physical and chemical factor indexs such as dissolved oxygen, the seed growing state is very good.Compare with breeding production in the past, throwing in the bait number of times obviously reduces, especially reduced the bait throwing in operation in the external net cage, both reduced production cost, alleviated labour intensity, again easy damaged material culture not, cleaning work also only needs regularly the collecting dung mesh bag of net cage bottom to be cleaned out to get final product, the seawater ecotope does not almost pollute around the culture experiment district, and water quality is good, and any disease does not take place seed; Secondly, owing to effectively utilized the adherance of Intranet box outer wall as sea urchin, sea cucumber etc., the bond area enlarged proximal of precious marine product is more than one times, therefore can not gather in heaps between the seed, and the bait of the most effectively sharing, look for food, death rate obviously reduces, so can increase the injected volume of precious marine product seed in right amount, increases substantially the culture benefit of unit of water body.After following table is off-test in 2 years, every breed achievement data table:
