Description

Fry marking device

Technical Field

The utility model relates to fry thickening equipment.

Background

The fry marking thick is the process from the egg yolk fry just hatched to the growth of the fry to the cun fry, and the fry marking thick is an important stage of the fry breeding process and is also the most serious stage of loss. Because the fry has higher requirement on water quality and is very delicate, the fry has more critical requirements on the aspects of initial feed and the like; therefore, the overall survival rate of the fry is greatly reduced in case of misoperation.

The existing method for marking the thickness of the fresh water fry is generally carried out in a pond by using a purse net, water can be exchanged with the water in the pond at any time during marking, and the water quality inside and outside the purse net is ensured to be the same, so that the stress phenomenon is not easy to generate when the fry is marked to be thick and successfully placed in the pond. However, this way of thickening has obvious disadvantages: 1. the water quality in the pond is easily influenced by factors such as external pollution, weather change and the like, so that the water quality is severely fluctuated, and the survival rate of the fry with thick mark is further influenced; 2. because the pond has a large water body and cannot be operated at constant temperature, the fry cannot be marked thick out of season, and the economic benefit of a farm is seriously influenced; 3. a large amount of organic matters are accumulated in the pond due to long-term culture, and the organic matters are easy to generate harmful chemical substances (such as ammonia nitrogen, nitrite, hydrogen sulfide and the like) and are also easy to breed various pathogenic microorganisms such as viruses, bacteria and the like; the chemical substances and microorganisms are easy to cause the newly hatched fry to be sick or dead, and the overall survival rate of the fry is reduced; 4. some particularly delicate water bloom (such as micropterus salmoides water bloom) can be injured and die when encountering the purse net; 5. in the early stage of thick water bloom of the fry, farmers generally put live plankton such as the newly hatched fairy bugs, rotifers and the like as fry initial feeding. However, the feeding amount is difficult to be accurately controlled, so that farmers often feed the fries excessively to ensure the normal growth of the fries. The overfeeding initial baits are deposited at the bottom of the coarse marking area and then die and decay; leading to the growth of large numbers of harmful microorganisms in the target areas. These harmful microorganisms easily infect the fry with viruses, bacteria, etc., thereby causing the fry to be ill or dead. Under the condition that the purse net or the cement pond is thickened in the pond, because the area of the purse net area or the cement pond is large, dead and decayed initial baits are difficult to clean and discharge in time at the bottom of the thickening area, the disease or death of the fry is more serious, and the survival rate of the fry is not high.

Therefore, a special fry marking and thickening system is urgently needed to provide a proper and sanitary marking and thickening environment for the coarse marking and thickening of the fry, and the survival rate of the fry in the marking and thickening stage is further improved.
