So if you want to breed guppies, when to put guppy fry? How many of them are put in an acre? The following one to understand.
When to put in the osmanthus fish fry?
Osmanthus fish fry put time in the spring, probably in mid-April, some areas stocking time in late May to early June, from the regular osmanthus fish fry nursery to buy early-bred osmanthus fish fry, suitable for stocking specifications for the body length of 1.5 cm, before the release of the fry with 10 ml/m3 povidone iodine soaked in fish fry 10-15 minutes.
How many guppy fry are released per mu?
The stocking density of guppy fry is related to their specifications, generally 3,000-8,000 guppy fry per mu of 8-10 centimeters.
Precautions for stocking guppies
1, preparation before stocking
Guppies should do all the preparations before stocking, check whether the water inlet and outlet are intact to prevent leakage.
If problems are found, they should be solved immediately; secondly, we should observe the stocking of the water body, especially to understand the condition of the pond escaping fish, in order to get a clear picture of the bottom of the details, in order to facilitate the determination of the stocking varieties and the amount of stocking; and finally, we have to carry out an improvement of the water body.
Because of the high temperature, the water is generally turbid, more dirt in the water, the water quality is very poor, germs are easy to reproduce, the application of quicklime or alum and other water splashing, clarification of the water body, purify the water quality.
If the water body is thin, but also slightly fertilizer, cultivate natural bait in the water.
2, stocking operation
In order to reduce the stocking deaths, to ensure that the stocking effect, should be replenished species selection.
Selected guppy fry require intact scales and fins, strong jumping, lively swimming, fat body, no disease or injury.
The fish that are thin, unresponsive, congested and mechanically damaged should be eliminated.
When stocking, the fish species must be sterilized by drugs before being put into the water body to prevent the fish from carrying diseases into the pool and causing the spread of fish diseases.
Generally available 2%~3% salt water or 1ppm~2ppm crystal trichlorfon and other medicinal solution soaked for 3 minutes~5 minutes.
3, post-stocking management
Laurel fry stocked, we must do a good job of baiting, fertilization, water quality regulation, fish disease prevention and other items of work.
Feed is generally concentrate-based to accelerate the growth of fish.
The daily feeding amount of 5% to 8% of the total weight of the fish is more suitable, specific to the extent that there is a slight surplus after feeding.
In 7~10 days after stocking, use strong chlorine essence (0.3ppm), bleach (1ppm) and other splashing to kill bacteria; at the same time can be used at intervals of crystalline trichlorfon (0.4ppm), copper sulfate (0.5ppm) and ferrous sulfate (0.2ppm) combination of splashing to kill parasites, effectively prevent the occurrence of fish disease.
The above is about the osmanthus fish fry stocking introduction, general acidic pool as well as turbid water quality of the pool is not suitable for cultivation of osmanthus fish, in the cultivation of the former to do a good job of disinfection, you can appropriate sprinkle some lime.
At the same time, we should also pay attention to the stocking density of guppies, and supplement the feed in time so that the guppy fry can grow better.
