step three, daily management: the method is characterized in that the stable and good water quality and substrate environment are kept, attention must be paid constantly in management, medicines for improving water quality or substrates are thrown in 3-5 days every time, the substrates and the water quality are kept fresh, new and old water exchange is required to be carried out during each dosing, the ingestion condition and the satiety rate of the fry are observed, the amount of residual baits in the water body is mastered at any time so as to be adjusted in time, the bottom cleaning work is very important, the pollution absorption is carried out regularly every day, the pond is changed in time when the residual substances are found, the physiological and ecological reactions of the fry are closely watched, the fry generate individual differences due to different growth speeds, the obvious group differentiation can cause serious mutual cannibalism, and the screening cultivation is carried out as early as possible;
step four, disease prevention and control: the grouper fries are thick under the condition of high water temperature, water quality is easy to pollute along with secretion of metabolites, so diseases are easy to occur in the thick marking process, vibriosis and ichthyophthiriasis are the most frequently encountered, most of the vibriosis is caused by mildew and the like of pond residual substances and generally appears as ventral fin rot, the ichthyophthiriasis is probably occurred under any condition and mostly appears seasonally, and symptoms of the ichthyophthiriasis are shown as rot and ichthyophthiriasis of the head or all parts of the body, so that the work of fry disease prevention needs to be paid attention in the thick marking process of the grouper fries.
The method is characterized in that the method comprises the following steps of (1) selling a fry of the marine eel in No. 8 and No. 4, selling a fry in No. 9 and No. 16, and starting the preparation work from the bottom of 7 months after 50 days from the preparation work to the time when the fry is sold out:
1. the pond is cleaned, water starts to enter, a mesh bag for water inlet is 100 meshes, 4 mu and half of the pond takes 3 days for water inlet, and a bag of bleaching powder in 50 jin is used for water disinfection after water is added.
2. After the water body is disinfected for two days, sodium thiosulfate is used for water body detoxification, the bacteria and algae are supplemented the next day after detoxification, and after water culture, roe binding is started.
3. After the roes are determined, an incubation and spawning room is well prepared, water is pumped into an incubation bag of the spawning room in the morning of No. 8 month and No. 4, the water pumped into the incubation bag is filtered by a filter bag, the air pump is used for inflating and oxygenating after the water is pumped, oxygen is adjusted to the maximum, the water temperature in the incubation bag is measured in the first hour before the roes are prepared in the afternoon, ice is added for cooling when the water temperature is high, ice blocks are packed by the bag for cooling when the ice blocks are added, and the ice blocks are prevented from polluting incubation water after the ice blocks are melted.
4. When the fish eggs arrive, the fish egg bag is firstly placed in hatching water for several minutes to adapt to the temperature difference of the water once, then the fish eggs are placed in a hatching water body, the patrol is needed during the fish egg hatching period, the fish egg hatching progress is observed, and the oxygen is adjusted to be small after the fry flowers are hatched from the eggs.
5. Opening bait is cultured on the next day when roes are placed, the fish fries are placed into an outer pond from an incubation bag after opening the fish fries for three days, detoxification and stress medicine splashing are carried out on the water of the outer pond one hour before the incubation bag is opened, and the fish fries are fed with opening rotifers after the bag is opened, so that the fish fries are convenient to pass through the bait.
6. After seedlings are successfully fed, attention is paid to observing the number of rotifers in the pond, proper topdressing is carried out to keep the balance of the rotifers and algae, and the water color is kept. Feeding rotifers every day after opening the bag for one week, wherein the feeding amount is determined according to the rotifers in the pond, feeding frozen copepods after opening the bag for two weeks, and adding a little slow sinking feed (Tianma's Bao No. 0 feed) for domestication and feeding when feeding the frozen insects.
7. After one week of domestication, the feed is basically eaten, the floating water feed (No. Tianma ODA0 feed) needs to be fed, because the fry grows fast after the feed is fed, the feed is too fat after the fry is fed, the water quality and the pond bottom deteriorate, the fry needs to pass through the pond in time, the water in a new pond needs to be disinfected for the next day for detoxification before passing through the pond, the stomach opening of the fry is large after passing through the pond, the fry is different in size for a few days, and one pond of water needs to be prepared for use according to the size.
8. After the size is divided, the feeding can not be carried out immediately, the feeding can be carried out only in the next day, after the size is divided, the feeding is carried out according to three meals a day for the big, the feeding is carried out according to four meals a day for the small, and the small food is sold together.
9. Due to the fact that oxygen consumption of the seedlings of the sea eels is high, water needs to be added every day after the feeds are fed, water is added in the afternoon in the daytime, water is added all the time till the next morning in the evening, the pond is required to be on duty to observe the situation of dissolved oxygen in the evening, the water inflow needs to be increased when the dissolved oxygen is low, an oxygen increasing machine is added, and oxygen increasing preparation medicines are splashed.
10. Feeding is stopped one day before fry selling, oxygen consumption of the fry is low at night, the fry is convenient to drain at night and pull the net on the second day, preparation work of a net air pump is needed before the fry pulls the net, and due to the fact that oxygen consumption of the fry of the marine fishes is high, 8 and 9 points of water body dissolved oxygen rise, the fry is pulled down to be sold smoothly.
Through the operation, the grouper marking technology realizes the marking of the groupers through the establishment of marking conditions, bait feeding, daily management and disease prevention and control, ensures that small-sized grouper fries are placed in a pond or a fish pond with relatively good environment and are cultivated to a certain specification, improves the fry survival rate and shortens the cultivation time; meanwhile, the integral survival rate of the fry is relatively stable, the management and scientific bait casting of the fry are convenient, and the fry can be smoothly sold.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
