Description
Technical field
The invention belongs to fishes fishing method field, more particularly to a kind of ecological catching method of mountain stream small fishes.
Background technology
Fishery be people develop natural resources a kind of mode while be also one kind that nearly water resident obtains income
Means.In the mountain stream of place deep in the mountains, many economic values of surviving and nutritive value very high small fishes, but due to mountain stream
Extreme terrain, manually fish for difficulty very big.Most of people are fished for by the illegal means such as malicious fish, electric fish, fried fish tartar souce,
This generates great destruction to natural environment and the stock of fish.By looking through a great amount of information mountain stream fish has been obtained with on-the-spot investigation
Class is very sensitive to water level and temperature, because mountain stream current SEA LEVEL VARIATION is fast, mountain stream fish are in order to avoid stranded danger, in water level
There is upstream habit when reduction.For these stocks of fish of reasonable development under conditions of not welding, it is necessary to
Develop a kind of catching method of relatively simple, environmentally friendly mountain stream small fishes.
The content of the invention
It is an object of the invention to provide a kind of ecological catching method of mountain stream small fishes, to solve in above-mentioned background technology
The problem of proposition.
The operating procedure that a kind of mountain stream small fishes ecology is fished for is as follows:
1)Prepare fishing net bag
Fishing net bag is by fishing net 11 and the telescoping structure of the suit of collection fishing net bag 12, and mesh is 10mm;
2 addressings
The river course 2 at the relatively slow place in selection mountain stream streams, which is used as, fishes for place, and river course 2 has transverse direction drop, the i.e. side of river course 2
Riverbed be higher than the opposite side of river course 2 riverbed;Big small stone interlocks in riverbed, and upper strata is cobblestone, and lower floor is silt;
3 build masonry dam
Masonry dam 3 is built by starting point end of the high side in riverbed, masonry dam 3 is located at river course 2 perpendicular to river course 2, the terminal of masonry dam 3
It is interior, and the position that current do not produce lateral flow is terminated in, the dam body upstream face of masonry dam 3 is smooth, and masonry dam 3 must be higher by water surface 10cm
More than;
4 laying plastic sheetings
Plastic sheeting is overlayed at the upstream face lower end riverbed 2 of masonry dam 3, the side of plastic sheeting is laid in riverbed 2
On silt face, and it is compacted with sandy soil;The opposite side of plastic sheeting is after the completion of traverse furrow 5 and longitudinal furrow 6, and expansion is laid on meeting for masonry dam 3
On the water surface;
5 draw traverse furrow and longitudinal furrow
Back side in masonry dam 3, the traverse furrow 5 for being arranged parallel to along the bottom of masonry dam 3 masonry dam, perpendicular to masonry dam 3
Back side direction sets the longitudinal furrow 6 of more than two, and the longitudinal furrow 6 of more than two is connected respectively in parallel shape, and equidirectional one end
Traverse furrow 5;
The scupper of an insertion masonry dam cross section is opened up on the masonry dam 3 adjacent with bank, allow upstream water through scupper
Enter traverse furrow 5 and longitudinal furrow 6 through masonry dam 3, water will ensure there are current in only traverse furrow 5 and longitudinal furrow 6, dry up elsewhere;
6 place fishing net
Two fishing net bags are placed in traverse furrow 5, a fishing net bag is located near scupper, and ensures scupper in fishing net bag
Net bottom rear, another fishing net bag is positioned over the other end of traverse furrow, and two network interfaces are relative;
Banished against the current in every longitudinal furrow 6 and put a fishing net bag, net bottom is respectively put towards masonry dam 3, and in net and at import
One block of stone, contacts network interface and riverbed, prevents from escaping fish;
7 receive net
Above-mentioned steps are completed, are waited on bank, substantial amounts of fish can be countercurrently poured into fishing net bag during this, when the He of longitudinal furrow 6
In traverse furrow 5 quantity of fish than it is sparser when, receive net, fish for end;
8 recover riverbed
Fish for after end, pack up plastic sheeting 4, be bulldozed masonry dam 3, recover original natural environment, be truly realized green, ring
Protect.
It is specific to be described as follows using instrument and operating condition:
The length of the fishing net 11 is 30cm, and in funnel-form, import large outlet is small;Collection fishing net bag 12 length be
60cm, one end is import, and the other end is blind end.Fishing net 11 is located in collection fishing net bag 12, and the import of the two passes through iron ring
Overlapping connection, realizes totally one import of two nets.
A diameter of 20cm of the import of fishing net 11, a diameter of 5cm of outlet.
The depth of water in the river course 2 is below 30cm.
The river course 2 includes branch type river course and wide water surface river course;
Branch type river course is divided into two strands of current from lateral middle by eyot, this two strands of current in downstream nearby again
Again one stream of water is pooled;Masonry dam 3 in branch type river course will block the high side river course in riverbed completely at bifurcation mouth, allow
The current side river course low from riverbed flows away;
Wide water surface river course is that the river course water surface is broad, without island, current not bifurcated, and the high one side water in riverbed is shallower relatively to be delayed,
The low one side water in riverbed is relatively deep more anxious, and the high side water surface in the riverbed side low higher than riverbed, and current have transverse direction in this place
Flowing;The length of masonry dam 3 in wide water surface river course will build the unconspicuous position of current lateral flow always.
The place of masonry dam 3 is built in step 3 in the high side in riverbed, a bar ditch are first drawn with hoe, the building stones come is drawn out and builds product
In the downstream of ditch as the dam foundation, larger cobblestone is then moved to take again and is built on the dam foundation;The dam foundation width of masonry dam 3 is 30cm,
Highly it is 20cm.Masonry dam total height is defined to be higher by water surface 10cm.
The width of plastic sheeting 4 described in step 4 is more than 0.8m, and length is more than 20m.
The depth of traverse furrow 5 and longitudinal furrow 6 is 9~11cm in step 5;A width of 30cm of traverse furrow 5, bottom of trench is less than riverbed
15cm;The width of longitudinal furrow 6 is 18~22cm.
The advantageous effects of the present invention embody in the following areas:
1. the present invention dexterously make use of mountain stream small fishes to avoid the stranded and upstream life when water level is reduced
Habit living;Fishing tool is cheap, simple, be easy to get, no mechanically actuated, and no material consumption and chemicals, the fast quick-recovery of energy are original certainly
Right environment, environmental protection.
2. fishing net is dexterously divided into two regions of fishing net and dress fishnet by the present invention, makes the fish of network access be difficult to escape, catch
Drag for excellent effect;And 10mm mesh size can filter the juvenile fish within an age, an adult fish more than age is only fished for, reasonable
On the basis of fishing for, the regeneration of the stock of fish is effectively protected.
