Abalone is a precious marine creature that is prized for its unique taste and nutritional value. Many people wonder if abalone can be farmed in captivity. The technical and environmental requirements for abalone farming are described in detail below.
1. Artificial breeding technology
1.Breeding facilities.
The artificial cultivation of abalone requires good breeding facilities, including breeding ponds, filtration equipment, oxygenation equipment, feed feeding machines, etc. The size and shape of the culture pond should be suitable for the growth and reproduction of abalone, with good drainage and aeration systems. Filtration equipment can remove impurities and harmful substances in the water and ensure clean water quality.
2.Breeding density.
The breeding density of abalone needs to be controlled according to the actual situation, and it is generally recommended to breed 5-10 abalone per square meter. Too high a culture density can lead to water quality deterioration and disease outbreaks, while too low a culture density can lead to a waste of resources.
3.Feed management.
The feed of abalone needs to choose a nutritious and reliable feed, and the ratio is based on the growth stage and needs of the abalone. It is recommended to feed at regular intervals, 2-3 times a day, and pay attention to the feeding situation and health status of abalone.
4.Water quality management.
The growth of abalone requires a good water quality environment, so it is necessary to regularly test the water quality, including pH, ammonia nitrogen, nitrite and other indicators. At the same time, it is necessary to keep the water quality stable and fresh to avoid the impact of sudden changes in water quality on abalone.
5.Disease prevention and control.
The disease prevention and control of abalone needs to adopt the principle of prevention first, maintain environmental hygiene, strengthen feeding management, and avoid the occurrence of diseases. If a disease is found, it is necessary to take ** measures in time, including medication**, isolation, etc.
2. Environmental requirements
1.Water temperature.
Abalone has high water temperature requirements, and the suitable water temperature range is 15 -25. In the process of breeding, it is necessary to keep the water temperature stable and suitable to avoid the impact of water temperature fluctuations on abalone.
2.Salinity.
Abalone needs to grow in a certain salinity environment, and the suitable salinity range is 25 -35. In the process of farming, it is necessary to control the change of salinity to avoid the impact of sudden changes in salinity on abalone.
3.Water quality.
Abalone growth requires clear water, adequate oxygen and suitable pH, among other things. In the process of breeding, it is necessary to regularly test the water quality and take corresponding measures to maintain the stability and suitability of the water quality. At the same time, the use of mariculture should be avoided as much as possible, because the high salinity in seawater will cause the abalone to lose water quickly, resulting in the death of the abalone. Freshwater aquaculture can make abalone survive better.
4.Illumination.
The growth of abalone needs sufficient light, so it is necessary to set up suitable lighting equipment in the breeding site to provide sufficient light conditions. At the same time, it is necessary to avoid the impact of too much or too little light on the abalone. Generally, the light time is maintained at 10-15 hours to meet its basic growth needs. Of course, different species of abalone may have slightly different light requirements. For example, some deep-sea species of abalone have a higher need for light;Some shallow-sea species of abalone have a lower need for light. Therefore, the specific situation also needs to be combined with the species of abalone and the actual situation to determine the most suitable light conditions.
