Abstract
The invention discloses a kind of method for removing epinephelus lanceolatus fish parasitism fish leech, the formaldehyde sea water solution of present invention 0.6%-0.7% concentration impregnates grouper 30-40 seconds, and fish leech can be caused to fall off death.Epinephelus lanceolatus fish is impregnated using the present invention, can achieve the purpose that the fish leech of parasitism with killing and any damage and harm are caused to fish itself.It is practiced and is detected, after method of the invention, the fish leech colonized in epinephelus lanceolatus fish all falls off to die of illness and die, and epinephelus lanceolatus fish has no adverse reaction.
Description
Technical field
The present invention relates to a kind of methods for removing epinephelus lanceolatus fish parasitism fish leech, belong to aquaculture field.
Background technique
Epinephelus lanceolatus fish (Epinephelus lanceolatus) it is commonly called as dragon wholesale, rough gentian grouper, belong to Perciformes
(Perciformes), fin section (Serranidae), Epinephelus (Epinephelus).Epinephelus lanceolatus fish has " king of grouper "
Title, be the maximum type of figure in ablen, the long 270cm of largest body, weight is up to 400kg or more.Epinephelus lanceolatus fish
Growth is rapid, and delicious meat, and nutritive value is high, has high economic development value.Have become southern littoral at present
One of the important species of area's ablen cultivation.But with the continuous increase of Grouper cultivating density, breeding environment is increasingly
Deteriorate, cause in recent years grouper piscicolasis take place frequently, and have spreading trend.
Fish leech is commonly called as seawater leech, eupolyphage sece steleophaga, black worm etc., is one of Grouper cultivating epizoa, and main parasitic exists
The pectoral fin and pectoral fin base portion of grouper fish body, next is colonized on the head of fish body, dorsal fin and tail fin, is also had in grouper eyes
A example of upper parasitism.Fish leech reproduction speed is fast, and it is serious to will cause the rotten body of grouper of cultivation, syntexis, malnutrition, the underproduction, more
It is the possibility fallen ill on a large scale as the medium initiation cultivation fish of the transmissions such as blood bacterium, virus, helminth, to grouper
Large-scale cultivation brings about great losses.
Fish leech is adsorbed on the body surface naked eyes of epinephelus lanceolatus fish as it can be seen that polypide elongate, is about 0.9-1.5cm, in dark brown
Color has link, flexible, and body body front and back respectively has a sucker, and anterior sucker is smaller, for being adsorbed in host to suck host's blood
Liquid, posterior sucker is larger, for adsorbing host, anterior sucker is assisted to creep or wriggle in sick fish body table, and polypide flexibility is good, be not easy by
It pulls out.
Summary of the invention
The problem to be solved by the invention is to provide a kind of methods for removing epinephelus lanceolatus fish parasitism fish leech, overcome and cultivate
In journey girth grouper easily by fish leech parasitism, cause epinephelus lanceolatus fish fall ill on a large scale in addition the underproduction harm.
To solve the above-mentioned problems, following technical proposals are used, a method of epinephelus lanceolatus fish parasitism fish leech is removed,
Mainly include the following steps: that concentration 37%-40% formalin is added filtering sea to be configured to the volume of 0.6%-0.7% containing formaldehyde by (1)
The medical fluid of concentration；(2) the epinephelus lanceolatus fish for being adsorbed with fish leech is pulled out, is put into the medical fluid of above-mentioned preparation and impregnates 30-40s；(3)
By epinephelus lanceolatus fish pull out to get.
The present invention using formaldehyde can disinfection the characteristics of, make the formaldehyde sea water solution of suitable concentration, and lead to
The Best Times that overtesting searches out this concentration of arranging in pairs or groups immerse the first of the concentration so that epinephelus lanceolatus fish is interior in this time frame
Aldehyde sea water solution can achieve the purpose that the fish leech of parasitism with killing and cause any damage and harm to fish itself.Through
It practices and detects, after method of the invention, the fish leech colonized in epinephelus lanceolatus fish all falls off to die of illness and die, girth stone
Spot fish has no adverse reaction.
Specific embodiment:
Further description of the technical solution of the present invention by the following examples.
Embodiment 1
Prepare a diameter 60cm, the plastic big basin of high 20cm contains filtering sea water 10L, and the formaldehyde that volumetric concentration 37% is added is molten
Liquid 60ml.The epinephelus lanceolatus fish for being adsorbed with the cultivation of a fish leech more than 20-30 is put into plastic big basin, is fished out rapidly after impregnating 40s
Go back to pond.
Embodiment 2
Prepare a diameter 60cm, the plastic big basin of high 20cm contains filtering sea water 10L, and 38% formalin of volumetric concentration is added
65ml.It pulls out and is adsorbed with the epinephelus lanceolatus fish of a fish leech more than 30-40 and is put into plastic big basin, fish out go back to pond rapidly after impregnating 35s.
Embodiment 3
Prepare a diameter 60cm, the plastic big basin of high 20cm contains filtering sea water 10L, and 40% formalin of volumetric concentration is added
70ml.It pulls out and is adsorbed with the epinephelus lanceolatus fish of a fish leech more than 10-20 and is put into plastic big basin, fish out go back to pond rapidly after impregnating 30s.
Method in -3 in accordance with the above-mentioned embodiment 1, the fish leech adsorbed on sick fish all fall off death, and grouper is without bad anti-
It answers.
Claims (1)
1. a kind of method for removing epinephelus lanceolatus fish parasitism fish leech, mainly includes the following steps: (1) by concentration 37%-40% formaldehyde
Solution adds filtering sea to be configured to the medical fluid of 0.6%-0.7% volumetric concentration；(2) the epinephelus lanceolatus fish for being adsorbed with fish leech is pulled out,
It is put into the medical fluid of above-mentioned preparation and impregnates 30-40s；(3) by epinephelus lanceolatus fish pull out to get.
