The utility model is further illustrated below by one embodiment.
(1) time for most preferably moving pond operation determines
In the fish early stage seed rearing stage, constitution is more fragile, therefore, often carries out when seed size is larger
Transplanting seedlings, it is ideal to operate.But in the actual production process, more late shifting pond, although seed size is larger, bottom of pond is dirty
The accumulation of object is then even more serious, and the water quality deterioration risk as brought by bottom of pond dirt is bigger, therefore, basis is generally required in production
Seed physical condition and bottom of pond dirt accumulation situation, comprehensive analysis determine optimal shifting pond operation or soil pick-up operating time.
The use of silvery pomfret Juvenile fish linking breeding apparatus in the present embodiment, except consideration seed physical condition and bottom of pond dirt
It accumulates outside situation, it need to also the three-dimensional distribution situation that special consideration should be given to seeds in pond.In the production nursery stage, silvery pomfret is from larval stages
To between postlarva mid-term stage, most seeds are distributed in water body upper layer, and after the postlarva middle and later periods, the distribution of seed is gradually
Start to be layered, therefore, the use of the silvery pomfret Juvenile fish linking breeding apparatus in the present embodiment is only capable of before postlarva mid-term.Consider
When just switching to postlarva to silvery pomfret, constitution is still relatively fragile, for this purpose, devising following experiment content to determine the best shifting pond time:
First group, postlarva initial stage (after reaching postlarva stage 1 week) moves pond；Second group of postlarva mid-term (after reaching postlarva stage 2 weeks) moves pond,
Each group sets 3 repetitions.By the present apparatus, diving being opened certainly and is pumped up, seed is dead in 3 days behind detection seed shifting pond rate, shifting pond after 12h
Die rate.Experimental result is shown in Table 1, as can be seen from Table 1, moves between two groups of survival rate behind pond in 3 days and there was no significant difference, but move
But there were significant differences for pond rate, and postlarva initial stage group moves pond rate and is significantly higher than postlarva mid-term group (P < 0.05).Postlarva mid-term group moves pond rate
Low reason essentially consists in, and with the increase of seed size, autonomous swimming ability is enhanced, so as to cause due to water between pond
The passive transfer rate that potential difference is caused decreases.Therefore, comprehensive analysis thinks, at silvery pomfret postlarva initial stage between postlarva mid-term
(entering postlarva stage 1 week) transplant seedlings operating.
1 different time of table moves Chi Xiaoguo
| Postlarva initial stage | Postlarva mid-term | |
| Seed moves pond rate (%) | 96.82±2.15a | 89.11±2.98b |
| The death rate (%) in 3 days | 1.95±0.33 | 2.06±0.52 |
Note: significant difference (P < 0.05) is indicated with a line difference Superscript letters.
(2) actual production is tested
Experiment set three processing groups, respectively artificially move pond operational group, inhale bottom remove contamination processing group and linking cultivation processing
Group (the utility model), each processing set three repetitions.The purpose of experiment is to verify analysis under actual production conditions, uses
Which kind of mode is operated, and is more advantageous to and is improved final nursery success rate.It is artificial move pond operational group be connected cultivation processing group

Feed mode, move into pond toward seed and launch the food organisms such as chlorella concentrate and artemia nauplii, artificial pond of moving operates
It is using water ladle, submersible is transplanted seedlings, and linking terminates after cultivating processing group whole device operation (water pump unlatching) 12 hours.
Inhaling bottom processing group of removing contamination is method using siphon, and bottom of pond dirt is cleared up.Three processing groups at postlarva initial stage into
Row enters after postlarva stage 7 days.After experiment, the death rate of each processing group after operation in 7 days is tested and analyzed,
And the final survival rate until juvenile fish stage is counted since the postlarva.Experimental result is shown in Table 2.As can be seen from Table 2, by this reality
With novel, seed cumulative mortality in 7 days is minimum, substantially less than other two processing groups.Meanwhile the utility model makes
With obtaining the final survival rate of highest Juvenile fish.Inhale bottom remove contamination processing group effect it is least ideal, reason essentially consists in suction
While dirt operation, causing bottom of pond dirt, largely disperse seriously destroys pool inner water matter situation, in turn in water body
Cause the mortality of seed.It removes contamination processing group although artificially moving pond and operating its effect significantly better than bottom is inhaled, is giving birth on a large scale
In the case of delivery and feed infant seedling, manual operation is excessively cumbersome, and time-consuming and laborious.
2 different operation processing group experimental result of table
| It is artificial to move pond group | Bottom is inhaled to remove contamination group | It is connected cultivation group | |
| The death rate (%) in 7 days | 23.26±3.08b | 55.37±8.29a | 5.29±1.02c |
| The final survival rate of Juvenile fish (%) * | 28.21±2.97b | 17.42±3.05c | 54.17±7.91a |
Note: indicating significant difference (P < 0.05) with a line difference Superscript letters, * only count the Juvenile fish stage finally at
Motility rate, and non-final emergence rate.
