Abstract
The invention relates to a disease prevention and control method for offshore net-cage-cultured fishes. The method specifically comprises the following steps: (1) carrying out deinsectization before fry stocking: dipping fries transferred from other places with fresh water for 15-25 minutes before stocking, and controlling the temperature of water to be about 23 DEG C; (2) carrying out disease prevention and control during fry feeding, specifically including: (a) carrying out control on benedenia seriolae such as trachinotus ovatus and groupers, and dipping fish bodies with fresh water for 10-20 minutes once every 21 to 31 days; and (b) carrying out control on gill rot of fishes such as trachinotus ovatus and pagrosomus major, cleanly washing and changing net cages before high-temperature seasons, and continuously hanging bleaching powder bags at a neap tide period for 2 to 3 days, wherein the bleaching powder bag of 250g is hung for 3 to 4 square meters; and (3) carrying out disease prevention and control on adult fishes. According to the method, the prevention and control on diseases and insect pests of the offshore net-cage-cultured fishes can be carried out effectively, the breeding effect is improved, and the development of fish breeding and poultry raising is facilitated.
Description
Technical field
The present invention relates to a kind of coastal waters cage-farming pest control method, belong to cultural technique field.
Background technology
At present, China coastal seas cage culture progressively grows up. Superior inshore fishing environment combines with the cage culture technology of high yield, changes traditional simple fishing operation pattern, produces the aquatic products of high-quality, define the efficient market competitiveness, promotes coastal waters cage culture to develop rapidly. Cage culture has an a variety of mode, selects the floating platform that floating drum is built, and water-bed part uses fishing net stable breeding, forms the selection that natural fishing ground is present many people. Along with the high speed development of coastal waters cage culture industry, the disease of harm cage-farming also gets more and more.
Summary of the invention
It is an object of the invention to provide a kind of coastal waters cage-farming pest control method, in order to carry out the preventing and treating of pest and disease damage better for cultured fishes.
To achieve these goals, technical scheme is as follows.
A kind of coastal waters cage-farming pest control method, specifically includes:
(1) seed gives deinsectization before putting in a suitable place to breed: the fry called in from other places, must use fresh water dipping bath 15 minutes��25 minutes before putting in a suitable place to breed, and water temperature need not be on the rocks at about 23 DEG C, if water temperature is more than 23 DEG C, and must with ice block cooling to 23 DEG C. The water the sterilized bolting silk net filtration of 80 orders, collects and kills polypide, then water is poured into marine. If it find that the fry gill has the parasite of Vermes, 1%��3% saline solution dipping bath fish body can be adopted 10 minutes��20 minutes, or with concentration 1g/ cubic meter��2g/ cubic meter potassium permanganate solution dipping bath 10 minutes��20 minutes.
(2) seed carries out the preventing and treating of disease in raising, and specifically includes:
The prevention and controls of the Ben Nideng worms such as (a) avette silvery pomfret, cabrilla every 20 days��30 days with fresh water dipping bath fish body 10 minutes��20 minutes, the abridged edition Buddhist nun breeding in 7 days��10 days of stepping on worm of summer, autumn once, adopts corresponding measure every 10 days��12 days with fresh water dipping bath fish body 10 minutes��20 minutes; Or embathe fish body 3 minutes��5 minutes with formalin (formaldehyde) 100mL addition 400kg water (fresh water), kill polypide. After dipping bath, water is not directly poured into marine, polypide be collected by filtration through 80 mesh sieve tulles, it is to avoid polypide infects fish body again.
(2), before the preventing and treating high temperature season of the fish gill-rot diseases bacterium such as avette silvery pomfret, snapper arrives, net cage is changed clothes totally, during little tidewater, uses bleaching powder hanging bag, 3 square metres��4 square metres hanging bag 250g, it is used in conjunction 2 days��3 days. Finding fish body gill rot, in time looking into without parasite, available ClO 2 solution dipping bath fish body 5 minutes��10 minutes, concentration is 2g/ cubic meter��4g/ cubic meter. Noting oxygen supplement in water, water temperature controls at about 23 DEG C.
(3) preventing and treating that the fish skin such as avette silvery pomfret, Sciaenops ocellatus is sick was after fish body is injured, with the ClO 2 solution dipping bath that concentration is 2g/ cubic meter��4g/ cubic meter 5 minutes��10 minutes. Noting oxygen supplement in water, water temperature controls at about 23 DEG C.
(4) the preventing and treating 2g/ cubic meter��3g/ cubic meter copper-bath dipping bath 20 minutes��30 minutes of the balantidiasis such as avette silvery pomfret, snapper Fish Trichodina; Or with 2g/ cubic meter��3g/ cubic meter Schweinfurt green solution dipping bath 15 minutes��30 minutes. Noting oxygen supplement in water, water temperature controls at about 23 DEG C. Marine fish also can use fresh water dipping bath 15 minutes��25 minutes, and effect is more preferably.
(5) the preventing and treating Bulbus Allii preventing and treating bacterial enteritis that the fish enteritis such as avette silvery pomfret, snapper is sick, every kilogram of fish body body weight 10g��25g, it is used in conjunction 4 days��6 days; Allicin powder preventing and treating bacterial enteritis, every kilogram of fish body body weight 0.2g, it is used in conjunction 4 days��6 days. SANHUANGFEN (namely Radix Et Rhizoma Rhei, Radix Scutellariae, Cortex Phellodendri) prevent and treat bacterial enteritis, mix bait and throw something and feed, every kilogram of fish body body weight with 5g��10g, 2g��4g, 3g��6g, is used in conjunction 5 days��7 days respectively.
(6) Virus disease of fish prevention May��August is the virosis high-incidence season, the betagen solution dipping bath of available 1g/ cubic meter��2g/ cubic meter prevents for 15 minutes��20 minutes.
(3) prevent and treat for adult fish disease, specifically include:
Preventing and treating 3%��5% saline solution dipping bath 5 minutes of (a) sea dish worm;
The mastigophorous preventing and treating formalin dipping bath of (b) starch 15 minutes��20 minutes, concentration is 250mL/ cubic meter; Or with copper sulfate dipping bath 15 minutes��20 minutes, concentration was 1g/ cubic meter��2g/ cubic meter. If adding fresh water, effect is more preferably.
(3) China's limnotrachelobdellaiosis prevent and treat water temperature below 18 DEG C time China lake trematodiasis start parasitism, the China lake trematodiasis self falling when water temperature rises to more than 23 DEG C. Outdoor cage culture cannot artificially regulate water temperature, so only with Drug therapy, may select in little tidewater bleaching powder hanging bag or hang bottle with metrifonate.
This beneficial effect of the invention is in that: this cultural method can be prevented and treated pest and disease damage for coastal waters cage-farming effectively, improves culture efficiency, contributes to the development of aquaculture.
