Abstract
The invention discloses a method for catching bottom fish of large-size and medium-size aquaculture water areas, belonging to the field of freshwater fish catching. According to the method, a water area suitable for fishery is selected through investigation by using the activity habits of fish in inland lakes unavailable for fish catching by drying ponds up, or other large-size and medium-size culture (breeding) water surfaces, and is subjected to target location, and then underwater holes (namely fish nests) and grooves (namely fish pits for gathering fish), which are of a meshy structure, are excavated according to location sites, so that the bottom fish in the water surface can enter the fish pits and swim to be gathered to the fish nests nearby, and a worker can catch the fish easily like catching a turtle in the jar. The method is a brand-new fish catching method for directly catching fish from the fish nests and is especially capable of improving the catching efficiency of the bottom high-quality fish.
Description
Technical field
The present invention relates to a kind of method that big-and-middle-sized Cultivated water fish on bottom layer is fished for, belong to fresh-water fishes and fish for field.
Background technology
Since reform and opening-up, China's freshwater aquaculture industry is fast-developing, and freshwater fish total amount leaps to the first in the world the sixth of the twelve Earthly Branches.The whole nation should fish and water territory propagated artificially by enforcement, Releasing and enhancing or protection breed, substantially all obtain exploitation in various degree.But, except Green grass, nearly all large and medium-sized lake is supported (increasing) and is grown waters because doing the pool when fish of gathering is obtained, the multiple fish on bottom layer such as mandarin fish and catfish, snakeheaded fish, carp, crucian, yellow wood fish, bream produced in this waters is caused to rely on traditional fishing gear, the fishing method fishing efficiency such as (as throw the net, draw in the net, bamboo weir paper tinsel) very poor, this not only causes the huge wasting of resources, and directly hinders mandarin fish and support (increasing) and grow big-and-middle-sized and throw seedling in waters and raise together with.
Mandarin fish is a kind of of high grade, price good, the market demand is prosperous famous-brand and high-quality aquatic products of tradition.Mandarin fish can in the growth of any freshwater and procreation, but due to the open-mouthed bait of mandarin fish birth must be than its individual little juvenile fish, thus very rare.And the open-mouthed bait of other the most fresh-water fishes aquatic zooplankton that is cladocera, copepoda etc., in water, storage greatly easily obtains.Therefore, the planting percent that mandarin fish breeds in its natural state is extremely low, and adult fish quantum of output is also just quite few.
And mandarin fish and other multiple fish on bottom layers have the habit in " depth of field water, cave of dwelling ", mostly live in seclusion in water-bed mud is delayed in season in midwinter, in the past, under someone wears rainwear, cave fishing at the bottom of natural water is found in lake, effect is very good, but this kind of method will be eliminated by pottery because the physical demands of people is large and production efficiency is low.
The present invention aims to provide a kind of catching method growing the fish on bottom layer in waters for large and medium-sized lake foster (increasing), especially the ecological catching method of mandarin fish and other multiple fish on bottom layers, not only can increase substantially the rate of recapture and the fishing efficiency of these fish on bottom layers, and can promote that mandarin fish is thrown seedling in big-and-middle-sized waters and raises together with, thus improve operator's comprehensive benefit.
Summary of the invention
The object that the present invention will solve is to provide a kind of support (increasings) and grows to big-and-middle-sized the method that waters fish on bottom layer fishes for, be bottom excavation fish nest and or fish-pit, until fish on bottom layer live in seclusion in fish nest with or fish-pit in time harvesting.
Described big-and-middle-sized foster (increasing) grows waters, refers to the medium-sized waters of area thousand mu of levels and the large-scale waters of ten thousand mu of levels.
Described cultivation refers to throw in fingerling (or fry), bait carry out omnibearing management in waters; Described propagation refers to does not throw fingerling, bait, some fries of releasing on a small quantity in waters, carries out strict phase of banning catching and protection of resources measure.
Described fish on bottom layer comprises the fish being accustomed to living in seclusion in underwater mud is delayed the winters such as mandarin fish, snakeheaded fish, catfish, yellow wood fish, carp, crucian.
Described fish nest is artificial or the machinery cave of excavating at the bottom.
Described fish-pit is artificial or the groove that excavates at the bottom of machinery.
In one embodiment of the invention, described fish nest is area 5m
2the cave that above shape is not restricted to one pattern.The flat shape of fish nest can be circular, square, rectangle or other arbitrary shapes.
In one embodiment of the invention, described fish-pit is the groove of wide 60-80cm, dark 60-80cm.
The present invention uses the structural fish nest fishing of fish nest and fish-pit composition or is used alone fish nest (cave) fishing, or is used alone fish-pit (i.e. groove) fishing.
In one embodiment of the invention, described method mainly comprises the following steps:
(1) fish for greatly winter early stage, comprehensive water-storage depth prospecting is carried out to Cultivated water, on this basis delimit account for certain limit profundal zone.
(2) fish nest location: select most deepwater field within the scope of the profundal zone determined, or near delivery port waters, or hard beach and mud in conjunction with waters by 3-10 hectares of fish nests of fixing a point, and number and establish mark.
(3) structure of fish nest
The first step: in selected fish nest position, the water-bed cave of not being restricted to one pattern by artificial or the above shape of mechanical means excavation area 5 square meter, this cave is fish nest.Described manual method draws earth with spade, or weight pressure Dang Ku; Described mechanical means uses slush pump or silt remover is taken out, soil of dredging, and the earth mechanically dug out must disperse placement beyond fish nest leeward and southwestward 20m, in case earth Rapid reset.
Second step: excavate the groove of a wide 50cm, deeply 50cm as fish-pit between adjacent two fish nests, fish nest and fish-pit carry out slitless connection, thus are combined as structural fish nest.
(4) fish is got: can fish with a net from nest after fish nest builds up three days.Operator can wear water jacket and directly enter that nest is free-hand to catch fish, or on fishing boat, holds long handle drag for and fish with a net from fish nest.
(5) fish nest is safeguarded: must once check at set intervals after structural fish nest comes into operation, and finds to silt up and must clear up recovery.
In one embodiment of the invention, when excessive the dividing some sections and number respectively of profundal zone area, and then selected fish nest position.
In one embodiment of the invention, the earth that excavation fish nest obtains disperses the waters be placed on beyond fish nest south orientation 20 meters, in case the earth Rapid reset dug out.
In one embodiment of the invention, during excavation fish-pit, the ship type groover (can be concrete prefabricated) of available long 80cm wide 50cm height 50cm weight 200kg puts into water, draws with motor vessel or winch and rolls along connecting two nest rectilinear directions.
In one embodiment of the invention, after fish nest, fish-pit build, also draw plane and satellite fix map immediately, so from the second year, only need do desilting finishing to fish nest system can reuse.As long as do permanent marker for the less water surface.
The present invention also provide a kind of fish on bottom layer especially mandarin fish raise together with catching method, at big-and-middle-sized Cultivated water, mandarin fish and surface fishes are carried out cover to support, the mandarin fish seed throwing in appropriate artificial propagation in summer is raised together with main breeding fish, fish for early stage winter at bottom excavation fish-pit and/or fish nest, treat that mandarin fish lives in seclusion in fish nest and/or fish-pit and supply dealer's harvesting.Although mandarin fish can natural propagation in river, river, lake, because its broken shell from ovum becomes the open-mouthed bait after fry must be fry, thus planting percent is extremely low, and the marketable fish by natural output is also just special few.Although support mandarin fish in cultivation or proliferation water nested domain can improve output, because harvesting is difficult, therefore very low from the efficiency of big-and-middle-sized Cultivated water recovery mandarin fish, the inventive method can improve mandarin fish capture rate more than 50%.
Fishery law of the present invention is suitable as inland big-and-middle-sized foster (increasing) and grows the complementary fishing method in waters, be mainly used in fishing for greatly the showdown of later stage to fish on bottom layer in autumn, winter to fish for, and the conventional fishing method to main breed fish (as four large Chinese carps) can not be replaced.The present invention utilizes mandarin fish and other several fish on bottom layer " depth of field water, to dwell cave " active behavior, big-and-middle-sizedly in the lake do not fished by the dry pool etc. support (increasings) and grow waters and should be positioned in fishing waters (profundal zone) by prospecting selection, press the anchor point cancellated cave under water of excavation (i.e. fish nest) and groove (i.e. fish-pit again, the ditch of poly-fish) make mandarin fish and other multiple fish on bottom layers in this waters enter fish-pit nearby and get together for fun in fish nest, operator can as the sure catch, just strech the hand and bring it back, one of fish brand-new fishing method convenient from fish nest.
The inventive method compares with other fishery law existing many advantages: (1) relievedly can throw in mandarin fish seed and raise together with main breeding fish in big-and-middle-sized waters, and more than increasing income two one-tenth thus; (2) cost of structural fish nest is built few, more cheap than purchasing netting gear; (3) catching rate and effect all can be enhanced about more than once than existing fishing gear, fishing method; (4) reserved resource, can go back water to heavy juvenile fish not up to standard and support; (5) production scale of famous and precious mandarin fish can be expanded, to enterprise's broaden sources of income and increasing income.
