Abstract

The invention relates to a method for net fishing, transporting and temporarily culturing coilia ectenes parent fish in a pool, belonging to the technical field of fish culture. The method is characterized by comprising the following process steps: (1) parent fish net fishing: carrying out net fishing by using a special net tool in the morning at 15-22 DEG C and transferring both water and fishesto a transport bucket by a basin; (2) parent fish transporting: fixing a layer of sponge on the inner wall of the transport bucket, treating transport water by precipitating and adding salt and maintaining transport time within 40 minutes; and (3) parent fish temporary culture: using a temporary pool which is an indoor cement pool and has an area of 20-40m<2> and the water depth of 0.8-1.0 m, andkeeping sufficient dissolved oxygen, proper light and certain flush water in the pool. The invention avoids desquamation and injury conditions of the coilia ectenes parent fish and effectively improves the transport and temporary culture survival rate of the coilia ectenesparent fish. Meanwhile, the invention also provides a feasible transport and temporary culture scheme for solving an artificial propagation technology of swimming fishes such as the coilia ectenes, and the like.

Description

A kind of pond support cutter long-tailed anchovy parent population draw in the net fish for, transportation and method for temporarily cultivating
Technical field
What the present invention relates to parent population in a kind of pond culture fish reproduction draws in the net to fish for, transport and support temporarily technology, specifically, be a kind of pond support cutter long-tailed anchovy parent population draw in the net fish for, transportation and method for temporarily cultivating, belong to the fish culture technical field.
Background technology
Cutter long-tailed anchovy (Coilia nasus) has another name called long jaw long-tailed anchovy, is commonly called as " hairtail ", is the famous and precious economic fish of enjoying one of " the Changjiang river three delicacies " good reputation.In recent years, because all multifactor influences such as the overfishing and the deterioration of the ecological environments, cutter long-tailed anchovy resource sharply failed, and the market demand is growing on and on, even to the awkward situation that has price but no buyers, pressed for and solve propagating artificially and propagation technique of cutter long-tailed anchovy.
The bottleneck that the pond cultivation technology that China Aquatic Science Research Academy Fresh Water Fishery Research Center and Jiangyin Shengang Sanxian Cultivation Co., Ltd. adopt the mode of irritating Jiang Namiao to solve the cutter long-tailed anchovy exists, and just succeeding aspect the artificial propagation techniques of cutter long-tailed anchovy.The cutter long-tailed anchovy belongs to the anadromous migration fish, ecological habit is comparatively special, very " tender and lovely ", stress reaction is strong, " promptly dried up dead ", and " just before giving birth " preceding parent population " fragility " especially, easy anoxic, easily injured, therefore, carry out artificial propagation at first to capture pond culture gonad maturity parent population draw in the net fish for, transport and support technical barrier temporarily, guarantee that the pond supports the survival rate of cutter long-tailed anchovy parent population.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, in conjunction with inherent physiological change of cutter long-tailed anchovy mating season and the synergistic principle of external environment, thereby provide a kind of pond support cutter long-tailed anchovy parent population draw in the net fish for, transportation and method for temporarily cultivating, reduce the damage of fish body, improve transportation survival rate and form motility rate temporarily.
According to technical scheme provided by the invention, a kind of pond of the present invention support cutter long-tailed anchovy parent population draw in the net fish for, transportation and method for temporarily cultivating, adopt the following processing step of supporting temporarily:
1, cutter long-tailed anchovy parent population draws in the net to fish for
1. water temperature: 15~22 ℃ early morning;
2. special netting gear: the netting gear bottom line of making at 10~16 order polythene net cloth is a long 1.0m every 0.5m, the chain stubble of heavy 1Kg;
3. draw in the net to fish for: keep the net sheet straight and upright when drawing in the net as far as possible, reduce the cutter long-tailed anchovy as far as possible and touch net, glue net; After parent population goes into the string bag, keep big water body, prevent cutter long-tailed anchovy parent population anoxic, and around the net sheet cutter long-tailed anchovy parent population relatively concentration zones begin, connect fish tape water and change in the transportation bucket with basin.
2, parent population transportation
1. transport bucket: bucket adopts plastics to make circle, and diameter 60~80cm, bucket inner wall be the thin sponge of one deck fixedly;
2. transport water: get clean pond water after precipitating 1~3 hour, handle with salt, salinity is 5~7 ‰ in the water of mixing back, brings moss when avoiding fish to change in the bucket into;
3. transportation: keep suitable traffic density, the water level in the carrying ladle is the high 4/7-6/7 of bucket, can take the micro-pore aeration oxygen-increasing device in the transportation, must guard against strong oxygenation, and haulage time remains in the 40min.Before the storage pond, holding pond, earlier the water temperature in the fishpond is adjusted under the fish, when going into the pond, carrying ladle is tilted to 90 ° gently, slowly after bucket end direction, take out carrying ladle, change fish over to storage pond, holding pond near transportation pond water temperature.
3, support temporarily
Storage pond, holding pond is indoor cement pit, and area is at 20~40m 2, the depth of water is at 0.8~1.0m.Storage pond, holding pond must keep sufficient dissolved oxygen, suitable light and certain bath flow velocity.
The density of cutter long-tailed anchovy parent population is 2~3 tails/10L water in carrying ladle during described the transportation;
The cutter long-tailed anchovy ripe fish density of supporting temporarily in the described storage pond, holding pond is: 1~3 tail/300L water;
Described storage pond, holding pond water is that underground phreatic water in cultivation base and cutter long-tailed anchovy parent population are cultured the pond pond water, and both proportions are 3: 4;
Described storage pond, holding pond bath flow velocity is at 0.1~0.3m/s.
The present invention compares with existing other similar techniques and has the following advantages:
1, the present invention provides truly feasible transportation, has supported the scheme thinking temporarily for the solution of the artificial propagation techniques of migration fishes such as cutter long-tailed anchovy;
2, the present invention can avoid the injured of cutter long-tailed anchovy parent population, effectively improve the transportation of cutter long-tailed anchovy parent population, form motility rate temporarily, and method is simple and convenient and easy to study.
